QUESTION 41

Refer to the exhibit. You are developing a migration plan to enable IPv6 in your IPv4 network. Starting at R3 and assuming default IS-IS operations, what is likely to happen when you enable IPv6 routing on the link from R3 to R2?

 

clip_image002

 

A.

Only R3 and R2 have IPv4 and IPv6 reachability.

B.

R2 receives an IPv6 default route from R3.

C.

Loopback reachability between all routers for IPv4 is lost.

D.

All routers except R2 are reachable through IPv4.

E.

R3 advertises the link from R3-R2 to R1, R4 and R5 only.

 

Correct Answer: C

 

 

QUESTION 42

A network designer is redesigning an enterprise campus network to ensure that Ethernet switches proactively attempt to reconnect after a fiber cut. In the design, they will have to address areas where fiber cuts exist on campus from past troubleshooting, where a single fiber is disconnected in the fiber pair, leading to looping. Which feature could be implemented in the design to allow the Spanning Tree Protocol on the switches to be protected?

 

A.

loop guard

B.

UniDirectional Link Detection

C.

UniDirectional Link Detection aggressive mode

D.

root guard

 

Correct Answer: C

 

 

 

QUESTION 43

In order to meet your service level agreement, your network designer created a design solution that includes interface dampening. In which two ways will interface dampening benefit your overall networ

k design? (Choose two.)

 

A.

Interface dampening uses an exponential backoff algorithm to suppress event reporting to the upper-level protocols.

B.

When the interface is dampened, further link events are not reported to the upper protocol modules.

C.

When the interface is dampened, further link events are reported to the upper protocol module.

D.

Periodic interface flapping that affects the routing system as a whole should have a period shorter than the system convergence time.

 

Correct Answer: AB

 

 

QUESTION 44

A planned EBGP network will use OSPF to reach the EBGP peer addresses. Which of these conditions should be avoided in the design that could otherwise cause the peers to flap continuously?

 

A.

An ACL blocks TCP port 179 in one direction.

B.

IP addresses used to peer are also being sent via EBGP.

C.

The OSPF area used for peering is nonbackbone (not area 0).

D.

The routers are peered by using a default route sent by OSPF.

 

Correct Answer: B

 

 

QUESTION 45

Refer to the exhibit. Your junior design engineer presents this configuration design. What is the next-hop router for CE3, and why?

 

clip_image004

 

A.

CE1. BGP weight is higher than CE2.

B.

CE2. EBGP administrative distance is lower than RIP.

C.

CE2. The link between CE2 and PE1 has more bandwidth than CE1-to-PE1.

D.

CE1. HSRP on CE1 is in active state.

 

Correct Answer: D

 

 

QUESTION 46

You are designing a Group Encrypted Transport Virtual Private Network solution consisting of 30 group members. Which measure helps protect encrypted user traffic from replay attacks?

 

A.

counter-based anti-replay

B.

time-based anti-replay

C.

nonce payload

D.

RSA-encrypted nonce

E.

digital certificates

 

Correct Answer: B

 

 

QUESTION 47

Refer to the exhibit. In this network design, where should summarization occur to provide the best summarization and optimal paths during a single-failure incident as well as during normal operation?

 

clip_image005

A.

a single identical summary for all the branch offices placed on routers 1A, 1B, 2A, and 2B

B.

two summaries on 1A and 1B, and two summaries on 2A and 2B

C.

a single identical summary on 3A and 3B

D.

a single summary on each aggregation device for the branches connected to them

 

Correct Answer: C

 

 

QUESTION 48

Refer to the exhibit. This diagram depicts the design of a small network that will run EIGRP on R1 and R2, and EIGRP Stub on R3. In which two ways will this network be impacted if there is link instability between R1 and R2? (Choose two.)

 

clip_image007

 

A.

R1 will have routes in its routing table that originate from R2 and R3.

B.

R3 will have routes in its routing table that originate from R1 and R2.

C.

R2 will have routes in its routing table that originate from R1 and R3.

D.

R3 will be transit for traffic between R1 and R2.

E.

R3 will not be transit for traffic between R1 and R2.

 

Correct Answer: BE

 

 

QUESTION 49

What is a design aspect regarding multicast transport for MPLS Layer 3 VPNs using the Rosen Draft implementation?

 

A.

LDP is the multicast control plane protocol.

B.

Multicast traffic is forwarded over GRE tunnels.

C.

Multicast traffic is forwarded over LDP or RSVP signaled LSPs.

D.

Using the MDT SAFI in BGP ensures that PIM can be disabled in the core.

 

Correct Answer: B

 

QUESTION 50

You are the lead network designer for an enterprise company called ABC, and you are leading design discussions regarding IPv6 implementation into their existing network. A question is raised regarding older Layer 2 switches that exist in the network, and if any changes are required to these Layer 2 switches for successful IPv6 implementation. Which two responses should you give? (Choose two.)

 

A.

IPv6 is transparent on Layer 2 switches, so there is no need to make any changes to the Layer 2 switches.

B.

If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support ICMPv6 snooping at Layer 2 switches.

C.

If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support DHCPv6 snooping at Layer 2 switches.

D.

If IPv6 multicast deployment is planned, then make sure that Layer 2 switches support MLD snooping at Layer 2 switches.

E.

If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support ND snooping at Layer 2 switches.

 

Correct Answer: AD
