Teststarter 300-101 Dumps Virtual Routing and Forwarding-Lite

In this 300-101 article I’m sharing the basics of VRF Lite with two practical labs. I’ve received a couple of requests about this some time ago so, here it is. Note that the second lab is one I found on the internet and made a few changes.

Service providers often need to allow their customers’ traffic to pass through their cloud
without one customer’s traffic (and corresponding routes) be exposed to another customer.

VRF configuration isn’t at all dependent on MPLS but often the two components are chosen to run together. In Cisco terminology, deployment of VRFs without MPLS is known as VRF Lite.

Similarly, enterprise networks might need to segregate various teststarter 300-101 dumps application types, such as keeping voice and video traffic separate from data. These are just a couple of scenarios that could benefit from the Cisco Virtual Routing and Forwarding (VRF) feature.

VRF allows a single physical router to host multiple virtual routers, with those virtual routers logically isolated from one another, each with its own IP routing table. Simply put it, VRF’s are VLANs for layer 3, and is the basics to understanding MPLS.

Question Set 1
QUESTION 1
Refer to the exhibit.
300-101

Based on this FIB table, which statement is correct?
A. There is no default gateway.
B. The IP address of the router on FastEthernet is 209.168.201.1.
C. The gateway of last resort is 192.168.201.1.
D. The router will listen for all multicast traffic.
Correct Answer: C
Explanation
Explanation/Reference:
Explanation:
The 0.0.0.0/0 route is the default route and is listed as the first CEF entry. Here we see the next hop for this default route lists 192.168.201.1 as the default router
(gateway of last resort).

 

 


QUESTION 2
Refer to the exhibit
300-101

A network administrator checks this adjacency table on a router. What is a possible cause for the incomplete marking?
A. incomplete ARP information
B. incorrect ACL
C. dynamic routing protocol failure
D. serial link congestion
Correct Answer: A
Explanation
Explanation/Reference:
Explanation:
To display information about the Cisco Express Forwarding adjacency table or the hardware Layer 3-switching adjacency table, use the show adjacency
command.
Reasons for Incomplete Adjacencies
There are two known reasons for an incomplete adjacency:
The router cannot use ARP successfully for the next-hop interface.
After a clear ip arp or a clear adjacency command, the router marks the adjacency as incomplete. Then it fails to clear the entry.
In an MPLS environment, IP CEF should be enabeled for Label Switching. Interface level command ip route-cache cef
No ARP Entry
When CEF cannot locate a valid adjacency for a destination prefix, it punts the packets to the CPU for ARP resolution and, in turn, for completion of the adjacency.

 

 

QUESTION 3
A network engineer notices that transmission rates of senders of TCP traffic sharply increase and decrease simultaneously during periods of congestion. Which
condition causes this?
A. global synchronization
B. tail drop
C. random early detection
D. queue management algorithm
Correct Answer: A
Explanation
Explanation:
TCP global synchronization in computer networks can happen to TCP/IP flows during periods of congestion because each sender will reduce their transmission
rate at the same time when packet loss occurs.
Routers on the Internet normally have packet queues, to allow them to hold packets when the network is busy, rather than discarding them.
Because routers have limited resources, the size of these queues is also limited. The simplest technique to limit queue size is known as tail drop. The queue is
allowed to fill to its maximum size, and then any new packets are simply discarded, until there is space in the queue again. This causes problems when used on
TCP/IP routers handling multiple TCP streams, especially when bursty traffic is present. While the network is stable, the queue is constantly full, and there are no
problems except that the full queue results in high latency. However, the introduction of a sudden burst of traffic may cause large numbers of established, steady
streams to lose packets simultaneously.

 

 


QUESTION 4
Which three problems result from application mixing of UDP and TCP streams within a network with no QoS? (Choose three.)
A. starvation
B. jitter
C. latency
D. windowing
E. lower throughput
Correct Answer: ACE
Explanation
Explanation/Reference:
Explanation:
It is a general best practice not to mix TCP-based traffic with UDP-based traffic (especially streaming video) within a single service provider class due to the
behaviors of these protocols during periods of congestion. Specifically, TCP transmitters will throttle-back flows when drops have been detected. Although some
UDP applications have application-level windowing, flow control, and retransmission capabilities, most UDP transmitters are completely oblivious to drops and thus
never lower transmission rates due to dropping. When TCP flows are combined with UDP flows in a single service provider class and the class experiences
congestion, then TCP flows will continually lower their rates, potentially giving up their bandwidth to drop-oblivious UDP flows. This effect is called TCP-starvation/
UDP-dominance. This can increase latency and lower the overall throughput.
TCP-starvation/UDP-dominance likely occurs if (TCP-based) mission-critical data is assigned to the same service provider class as (UDP-based) streaming video
and the class experiences sustained congestion. Even if WRED is enabled on the service provider class, the same behavior would be observed, as WRED (for the
most part) only affects TCP-based flows. Granted, it is not always possible to separate TCP-based flows from UDP-based flows, but it is beneficial to be aware of
this behavior when making such application-mixing decisions. Reference: 

 

 


QUESTION 5
Which method allows IPv4 and IPv6 to work together without requiring both to be used for a single connection during the migration process?
A. dual-stack method
B. 6to4 tunneling
C. GRE tunneling
D. NAT-PT
Correct Answer: A
Explanation
Explanation/Reference:
Explanation:
Dual stack means that devices are able to run IPv4 and IPv6 in parallel. It allows hosts to simultaneously reach IPv4 and IPv6 content, so it offers a very flexible
coexistence strategy. For sessions that support IPv6, IPv6 is used on a dual stack endpoint. If both endpoints support IPv4 only, then IPv4 is used.
Benefits:
Native dual stack does not require any tunneling mechanisms on internal networks
Both IPv4 and IPv6 run independent of each other
Dual stack supports gradual migration of endpoints, networks, and applications.

 

 


QUESTION 6
Which statement about the use of tunneling to migrate to IPv6 is true?
A. Tunneling is less secure than dual stack or translation.
B. Tunneling is more difficult to configure than dual stack or translation.
C. Tunneling does not enable users of the new protocol to communicate with users of the old protocol without dual-stack hosts.
D. Tunneling destinations are manually determined by the IPv4 address in the low-order 32 bits of IPv4-compatible IPv6 addresses.
Correct Answer: C
Explanation
Explanation/Reference:
Explanation:
Using the tunneling option, organizations build an overlay network that tunnels one protocol over the other by encapsulating IPv6 packets within IPv4 packets and
IPv4 packets within IPv6 packets. The advantage of this approach is that the new protocol can work without disturbing the old protocol, thus providing connectivity
between users of the new protocol. Tunneling has two disadvantages, as discussed in RFC 6144:
Users of the new architecture cannot use the services of the underlying infrastructure.
Tunneling does not enable users of the new protocol to communicate with users of the old protocol without dual-stack hosts, which negates interoperability.

 

 


QUESTION 7
A network administrator executes the command clear ip route. Which two tables does this command clear and rebuild? (Choose two.)
A. IP routing
B. FIB
C. ARP cache
D. MAC address table
E. Cisco Express Forwarding table
F. topology table

Correct Answer: AB
Explanation
Explanation/Reference:
Explanation:
To clear one or more entries in the IP routing table, use the following commands in any mode:
Command Purpose
clear ip route {* |
Clears one or more routes from both the
{route |
unicast RIB and all the module FIBs. The
prefix/length}[next-hop route options are as follows:
interface]}
· *–All routes.
[vrf vrf-name]
Example:
· route–An individual IP route.
switch(config)# clear ip
· prefix/length–Any IP prefix.
route
10.2.2.2
· next-hop–The next-hop address
· interface–The interface to reach the
next-hop address.
The vrf-name can be any case-sensitive, al
phanumeric string up to 32 characters.
Reference:

 

 


QUESTION 8
Which switching method is used when entries are present in the output of the command show ip cache?
A. fast switching
B. process switching
C. Cisco Express Forwarding switching
D. cut-through packet switching
Correct Answer: A
Explanation
Explanation/Reference:
Explanation:
Fast switching allows higher throughput by switching a packet using a cache created by the initial packet sent to a particular destination. Destination addresses
are stored in the high-speed cache to expedite forwarding. Routers offer better packet-transfer performance when fast switching is enabled. Fast switching is
enabled by default on all interfaces that support fast switching.
To display the routing table cache used to fast switch IP traffic, use the “show ip cache” EXEC command.
Reference:

 

 


QUESTION 9
Which two actions must you perform to enable and use window scaling on a router? (Choose two.)
A. Execute the command ip tcp window-size 65536.
B. Set window scaling to be used on the remote host.
C. Execute the command ip tcp queuemax.
D. Set TCP options to “enabled” on the remote host.
E. Execute the command ip tcp adjust-mss.
Correct Answer: AB
Explanation
Explanation/Reference:
Explanation:
The TCP Window Scaling feature adds support for the Window Scaling option in RFC 1323, TCP Extensions for High Performance . A larger window size is
recommended to improve TCP performance in network paths with large bandwidth-delay product characteristics that are called Long Fat Networks (LFNs). The
TCP Window Scaling enhancement provides that support. The window scaling extension in Cisco IOS software expands the definition of the TCP window to 32
bits and then uses a scale factor to carry this 32-bit value in the 16-bit window field of the TCP header. The window size can increase to a scale factor of 14.
Typical applications use a scale factor of 3 when deployed in LFNs.
The TCP Window Scaling feature complies with RFC 1323. The larger scalable window size will allow TCP to perform better over LFNs. Use the ip tcp window
size command in global configuration mode to configure the TCP window size. In order for this to work, the remote host must also support this feature and its
window size must be increased. 

The worldwide network landscape is continually changing with new technologies being introduced continually. The new revision of the Cisco ROUTE 300-101 exam is the most information packed addition to the CCNP Routing and Switching curriculum experienced to date! By the time you’re done watching, you’ll be ready to configure routing protocols at a master level; grasp the big-picture of worldwide Cisco CCNP network design; fill in plenty of “knowledge gaps” left by the CCNA on routing protocols; and confidently sit for the teststarter 300-101 dumps.

70-411 exam Question No : 32 – (Topic 0)  Your network contains an Active Directory domain named contoso.com. The domain
contains a file server named Server1 that runs Windows Server 2012 R2. Server1 has a
share named Share1.
When users without permission to Share1 attempt to access the share, they receive the
Access Denied message as shown in the exhibit. (Click the Exhibit button.)
70-411 exam

You deploy a new file server named Server2 that runs Windows Server 2012 R2.
You need to configure Server2 to display the same custom Access Denied message as
Server1.
What should you install on Server2?
A. The Remote Assistance feature
B. The Storage Services server role
C. The File Server Resource Manager role service
D. The Enhanced Storage feature
Answer: C
Explanation:
Access-Denied Assistance is a new role service of the File Server role in Windows Server
2012.

70-411 exam

We need to install the prerequisites for Access-Denied Assistance.
Because Access-Denied Assistance relies up on e-mail notifications, we also need to
configure each relevant file server with a Simple Mail Transfer Protocol (SMTP) server
address. Let’s do that quickly with Windows PowerShell:
Set-FSRMSetting -SMTPServer mailserver. nuggetlab.com -AdminEmailAddress
[email protected] -FromEmailAddress [email protected]
You can enable Access-Denied Assistance either on a per-server basis or centrally via
Group Policy. To my mind, the latter approach is infinitely preferable from an administration
standpoint.
Create a new GPO and make sure to target the GPO at your file servers’ Active Directory
computer accounts as well as those of your AD client computers. In the Group Policy
Object Editor, we are looking for the following path to configure Access-Denied Assistance:
\Computer Configuration\Policies\Administrative Templates\System\Access-Denied
Assistance

70-411 exam

The Customize message for Access Denied errors policy, shown in the screenshot below,
enables us to create the actual message box shown to users when they access a shared
file to which their user account has no access.

70-411 exam

What’s cool about this policy is that we can “personalize” the e-mail notifications to give us
administrators (and, optionally, file owners) the details they need to resolve the permissions
issue quickly and easily.
For instance, we can insert pre-defined macros to swap in the full path to the target file, the
administrator e-mail address, and so forth. See this example:
Whoops! It looks like you’re having trouble accessing [Original File Path]. Please click
Request Assistance to send [Admin Email] a help request e-mail message. Thanks!
You should find that your users prefer these human-readable, informative error messages
to the cryptic, non-descript error dialogs they are accustomed to dealing with.
The Enable access-denied assistance on client for all file types policy should be enabled to
force client computers to participate in Access-Denied Assistance. Again, you must make
sure to target your GPO scope accordingly to “hit” your domain workstations as well as
your Windows Server 2012 file servers.
Testing the configuration
This should come as no surprise to you, but Access-Denied Assistance works only with
Windows Server 2012 and Windows 8 computers. More specifically, you must enable the
Desktop Experience feature on your servers to see Access-Denied Assistance messages
on server computers.
When a Windows 8 client computer attempts to open a file to which the user has no
access, the custom Access-Denied Assistance message should appear:

70-411 exam

If the user clicks Request Assistance in the Network Access dialog box, they see a
secondary message:

70-411 exam

At the end of this process, the administrator(s) will receive an e-mail message that contains
the key information they need in order to resolve the access problem:
The user’s Active Directory identity
The full path to the problematic file
A user-generated explanation of the problem
So that’s it, friends! Access-Denied Assistance presents Windows systems administrators
with an easy-to-manage method for more efficiently resolving user access problems on
shared file system resources. Of course, the key caveat is that your file servers must run
Windows Server 2012 and your client devices must run Windows 8, but other than that, this
is a great technology that should save admins extra work and end-users extra headaches.

 

 

70-411 exam Question No : 33 – (Topic 0)  You have a server named Server1 that runs Windows Server 2012 R2. Server1 has the
File Server Resource Manager role service installed.
Each time a user receives an access-denied message after attempting to access a folder
✑ ✑ ✑ ✑ ✑ ✑ ✑
on Server1, an email notification is sent to a distribution list named DL1.
You create a folder named Folder1 on Server1, and then you configure custom NTFS
permissions for Folder1.
You need to ensure that when a user receives an access-denied message while attempting
to access Folder1, an email notification is sent to a distribution list named DL2. The
solution must not prevent DL1 from receiving notifications about other access-denied
messages.
What should you do?
A. From Server Manager, run the New Share Wizard to create a share for Folder1 by
selecting the SMB Share – Advanced option.
B. From the File Server Resource Manager console, modify the Access-Denied Assistance
settings.
C. From the File Server Resource Manager console, modify the Email Notifications
settings.
D. From Server Manager, run the New Share Wizard to create a share for Folder1 by
selecting the SMB Share -Applications option.
Answer: C
Explanation:
Configure the email notification settings
You must configure the email notification settings on each file server that will send the
access-denied assistance messages.
Open File Server Resource Manager. In Server Manager, click Tools, and then
click File Server Resource Manager.
Right-click File Server Resource Manager (Local), and then click Configure
Options.
Click the Email Notifications tab.
Configure the following settings:
In the SMTP server name or IP address box, type the name of IP address of the
SMTP server in your organization.
In the Default administrator recipients and Default “From” e-mail address boxes,
type the email address of the file server administrator.
Click Send Test E-mail to ensure that the email notifications are configured
correctly.
Click OK.

70-411 exam Question No : 34 HOTSPOT – (Topic 0) Your network contains an Active Directory domain named contoso.com. The domain
contains a server named Server1 that runs Windows Server 2012 R2. Server1 has the File
Server Resource Manager role service installed.
You need to configure Server1 to meet the following requirements:
Ensure that old files in a folder named Folder1 are archived automatically to a
folder named Archive1.
Ensure that all storage reports are saved to a network share.
Which two nodes should you configure?
To answer, select the appropriate two nodes in the answer area.

70-411 exam Question No : 35 DRAG DROP – (Topic 0)  You are a network administrator of an Active Directory domain named contoso.com.
You have a server named Server1 that runs Windows Server 2012 R2. Server1 has the
Web Server (IIS) server role installed.
Server1 will host a web site at URL The application pool
identity account of the web site will be set to a domain user account named AppPool1.
You need to identify the setspn.exe command that you must run to configure the
appropriate Service Principal Name (SPN) for the web site.
What should you run?
To answer, drag the appropriate objects to the correct location. Each object may be used
once, more than once, or not at all. You may need to drag the split bar between panes or
scroll to view content.
70-411 exam

 

70-411 exam Question No : 36 – (Topic 0)  Your network contains an Active Directory domain named contoso.com. The domain
contains a domain controller named DC1 that runs Windows Server 2012 R2. DC1 is
backed up daily.
The domain has the Active Directory Recycle Bin enabled.
During routine maintenance, you delete 500 inactive user accounts and 100 inactive
groups. One of the deleted groups is named Group1. Some of the deleted user accounts
are members of some of the deleted groups.
For documentation purposes, you must provide a list of the members of Group1 before the
group was deleted.
You need to identify the names of the users who were members of Group1 prior to its
deletion.
You want to achieve this goal by using the minimum amount of administrative effort. What should you do first?
A. Mount the most recent Active Directory backup.
B. Reactivate the tombstone of Group1.
C. Perform an authoritative restore of Group1.
D. Use the Recycle Bin to restore Group1.
Answer: A
Explanation:
The Active Directory Recycle Bin does not have the ability to track simple changes to
objects.
If the object itself is not deleted, no element is moved to the Recycle Bin for possible
recovery in the future. In other words, there is no rollback capacity for changes to object
properties, or, in other words, to the values of these properties.

QUESTION 21
What is a cause for unicast flooding?
A. Unicast flooding occurs when multicast traffic arrives on a Layer 2 switch that has directly connected multicast receivers.
B. When PIM snooping is not enabled, unicast flooding occurs on the switch that interconnects the PIM-enabled routers.
C. A man-in-the-middle attack can cause the ARP cache of an end host to have the wrong MAC address. Instead of having the MAC address of the default gateway, it has a MAC address of the man-in-the-middle. This causes all traffic to be unicast flooded through the man-in-the-middle, which can then sniff all packets.
D. Forwarding table overflow prevents new MAC addresses from being learned, and packets destined to those MAC addresses are flooded until space becomes available in the forwarding table.

Correct Answer: D Explanation
Explanation/Reference:
Causes of Flooding The very cause of flooding is that destination MAC address of the packet is not in the L2 forwarding table of the switch. In this case the packet will be flooded out of all forwarding ports in its VLAN (except the port it was received on). Below case studies display most common reasons for destination MAC address not being known to the switch. Cause 1: Asymmetric Routing Large amounts of flooded traffic might saturate low-bandwidth links causing network performance issues or complete connectivity outage to devices connected across such low-bandwidth links Cause 2: Spanning-Tree Protocol Topology Changes Another common issue caused by flooding is Spanning-Tree Protocol (STP) Topology Change Notification (TCN). TCN is designed to correct forwarding tables after the forwarding topology has changed. This is necessary to avoid a connectivity outage, as after a topology change some destinations previously accessible via particular ports might become accessible via different ports. TCN operates by shortening the forwarding table aging time, such that if the address is not relearned, it will age out and flooding will occur Cause 3: Forwarding Table Overflow Another possible cause of flooding can be overflow of the switch forwarding table. In this case, new addresses cannot be learned and packets destined to such addresses are flooded until some space becomes available in the forwarding table. New addresses will then be learned. This is possible but rare, since most modern switches have large enough forwarding tables to accommodate MAC addresses for most designs.

QUESTION 22
Refer to the exhibit.

Video Source S is sending interactive video traffic to Video Receiver R. Router R1 has multiple routing table entries for destination R. Which load-balancing mechanism on R1 can cause out-of-order video traffic to be received by destination R?
A. per-flow load balancing on R1 for destination R
B. per-source-destination pair load balancing on R1 for destination R
C. CEF load balancing on R1 for destination R
D. per-packet load balancing on R1 for destination R

Correct Answer: D Explanation
Explanation/Reference:
Per-packet load balancing guarantees equal load across all links, however potentially the packets may arrive out-of-order at the destination as differential delay may exist within the network.

QUESTION 23
What is Nagle’s algorithm used for?
A. To increase the latency
B. To calculate the best path in distance vector routing protocols
C. To calculate the best path in link state routing protocols
D. To resolve issues caused by poorly implemented TCP flow control.

Correct Answer: D Explanation
Explanation/Reference:
Silly window syndrome is a problem in computer networking caused by poorly implemented TCP flow control. A serious problem can arise in the sliding window operation when the sending application program creates data slowly, the receiving application program consumes data slowly, or both. If a server with this problem is unable to process all incoming data, it requests that its clients reduce the amount of data they send at a time (the window setting on a TCP packet). If the server continues to be unable to process all incoming data, the window becomes smaller and smaller, sometimes to the point that the data transmitted is smaller than the packet header, making data transmission extremely inefficient. The name of this problem is due to the window size shrinking to a “silly” value. When there is no synchronization between the sender and receiver regarding capacity of the flow of data or the size of the packet, the window syndrome problem is created. When the silly window syndrome is created by the sender, Nagle’s algorithm is used. Nagle’s solution requires that the sender sends the first segment even if it is a small one, then that it waits until an ACK is received or a maximum sized segment (MSS) is accumulated.

QUESTION 24
Which statement is true regarding the UDP checksum?
A. It is used for congestion control.
B. It cannot be all zeros.
C. It is used by some Internet worms to hide their propagation.
D. It is computed based on the IP pseudo-header.

Correct Answer: D Explanation
Explanation/Reference:
The method used to compute the checksum is defined in RFC 768:
“Checksum is the 16-bit one’s complement of the one’s complement sum of a pseudo header of information from the IP header, the UDP header, and the data,
padded with zero octets at the end (if necessary) to make a multiple of two octets.”
In other words, all 16-bit words are summed using one’s complement arithmetic. Add the 16-bit values up. Each time a carry-out (17th bit) is produced, swing that
bit around and add it back into the least significant bit. The sum is then one’s complemented to yield the value of the UDP checksum field. If the checksum
calculation results in the value zero (all 16 bits 0) it should be sent as the one’s complement (all 1s).

QUESTION 25
Which statement describes the purpose of the Payload Type field in the RTP header?
A. It identifies the signaling protocol.
B. It identifies the codec.
C. It identifies the port numbers for RTP.
D. It identifies the port numbers for RTCP.

Correct Answer: B Explanation
Explanation/Reference:
PT, Payload Type. 7 bits: Identifies the format of the RTP payload and determines its interpretation by the application. A profile specifies a default static mapping of payload type codes to payload formats. Additional payload type codes may be defined dynamically through non-RTP means. An RTP sender emits a single RTP payload type at any given time; this field is not intended for multiplexing separate media streams. A full list of codecs and their payload type values can be found at the link below:

QUESTION 27
Which circumstance can cause packet loss due to a microburst?
A. slow convergence
B. a blocked spanning-tree port
C. process switching
D. insufficient buffers

Correct Answer: D Explanation Explanation/Reference:
Micro-bursting is a phenomenon where rapid bursts of data packets are sent in quick succession, leading to periods of full line-rate transmission that can overflow packet buffers of the network stack, both in network endpoints and routers and switches inside the network. Symptoms of micro bursts will manifest in the form of ignores and/ or overruns (also shown as accumulated in “input error” counter within show interface output). This is indicative of receive ring and corresponding packet buffer being overwhelmed due to data bursts coming in over extremely short period of time (microseconds).
Reference: http://ccieordie.com/?tag=micro-burst
QUESTION 28
Which two statements about proxy ARP are true? (Choose two.)
A. It is supported on networks without ARP.
B. It allows machines to spoof packets.
C. It must be used on a network with the host on a different subnet.
D. It requires larger ARP tables.
E. It reduces the amount of ARP traffic.

Correct Answer: BD Explanation
Explanation/Reference:
Disadvantages of Proxy ARP
Hosts have no idea of the physical details of their network and assume it to be a flat network in which they can reach any destination simply by sending an ARP
request. But using ARP for everything has disadvantages. These are some of the disadvantages:
It increases the amount of ARP traffic on your segment.
Hosts need larger ARP tables in order to handle IP-to-MAC address mappings.

Security can be undermined. A machine can claim to be another in order to intercept packets, an act called “spoofing.”

It does not work for networks that do not use ARP for address resolution.

It does not generalize to all network topologies. For example, more than one router that connects two physical networks.

A. the forwarding information base
B. the label forwarding information base
C. the IP routing table
D. the label information table
E. the adjacency table

Correct Answer: AB Explanation
Explanation/Reference:
The control plane runs protocols such as OSPF, BGP, STP, LDP. These protocols are needed so that routers and switches know how to forward packets and
frames.
The data plane is where the actual forwarding takes place. The data plane is populated based on the protocols running in the control plane. The Forwarding
Information Base (FIB) is used for IP traffic and the Label FIB is used for MPLS.

QUESTION 32
Which option is the most effective action to avoid packet loss due to microbursts?
A. Implement larger buffers.
B. Install a faster CPU.
C. Install a faster network interface.
D. Configure a larger tx-ring size.

QUESTION 34
You are backing up a server with a 1 Gbps link and a latency of 2 ms. Which two statements about the backup are true? (Choose two.)
A. The bandwidth delay product is 2 Mb.
B. The default TCP send window size is the limiting factor.
C. The default TCP receive window size is the limiting factor.
D. The bandwidth delay product is 500 Mb.
E. The bandwidth delay product is 50 Mb.

Correct Answer: AC Explanation Explanation/Reference:
1 Gbps is the same as 1000 Mbps, and 1000Mb x .0002 = 2 Mbps. With TCP based data transfers, the receive window is always the limiting factor, as the sender is generally able to send traffic at line rate, but then must wait for the acknowledgements to send more data.
QUESTION 35

A. the transmitted octet
B. the lost packet count
C. session control function provisioning information
D. the CNAME for session participants
E. the authentication method
F. MTU size changes in the path of the flow Correct Answer: AB

Explanation Explanation/Reference:
RTCP transports statistics for a media connection and information such as transmitted octet and packet counts, packet loss, packet delay variation, and round-trip delay time. An application may use this information to control quality of service parameters, perhaps by limiting flow, or using a different codec.

QUESTION 36
How many hash buckets does Cisco Express Forwarding use for load balancing?
A. 8
B. 16
C. 24
D. 32

Correct Answer: B Explanation Explanation/Reference:
In order to understand how the load balance takes place, you must first see how the tables relate. The Cisco Express Forwarding table points to 16 hash buckets (load share table), which point to the adjacency table for parallel paths. Each packet to be switched is broken up into the source and destination address pair and checked against the loadshare table.
Reference: http://www.cisco.com/c/en/us/support/docs/ip/express-forwarding-cef/18285-loadbal-cef.html
QUESTION 37
Which three features require Cisco Express Forwarding? (Choose three.)
A. NBAR
B. AutoQoS
C. fragmentation
D. MPLS
E. UplinkFast
F. BackboneFast

Correct Answer: ABD Explanation Explanation/Reference:
QoS Features That Require CEF These class-based QoS features are supported only on routers that run CEF. Network Based Application Recognition (NBAR) provides intelligent network classification. For more information, refer to Network Based Application

Recognition.
The AutoQoS -VoIP feature simplifies and speeds up the implementation and provisioning of QoS for VoIP traffic. This feature is enabled with the help of the
auto qos voip command. CEF must be enabled at the interface or ATM PVC before the auto qos command can be used. For more information about this feature and its prerequisites, refer to AutoQoS – VoIP.
From MPLS Fundamentals – Luc De Ghein Why Is CEF Needed in MPLS Networks? Concerning MPLS, CEF is special for a certain reason; otherwise, this book would not explicitly cover it. Labeled packets that enter the router are switched according to the label forwarding information base (LFIB) on the router. IP packets that enter the router are switched according to the CEF table on the router. Regardless of whether the packet is switched according to the LFIB or the CEF table, the outgoing packet can be a labeled packet or an IP packet

QUESTION 38
Which two options are interface requirements for turbo flooding? (Choose two.)
A. The interface is Ethernet.
B. The interface is configured for ARPA encapsulation.
C. The interface is PPP.
D. The interface is configured for GRE encapsulation.
E. The interface is configured for 802.1Q encapsulation.

Correct Answer: AB Explanation Explanation/Reference:
In the switch, the majority of packets are forwarded in hardware; most packets do not go through the switch CPU. For those packets that do go to the CPU, you can speed up spanning tree-based UDP flooding by a factor of about four to five times by using turbo-flooding. This feature is supported over Ethernet interfaces configured for ARPA encapsulation.
