Service Provider Routing and Switching. Professional (JNCIP-SP) Questions and Answers

Question 1

Exhibit:

R1 assigns incoming voice traffic to the ef forwarding class. All other traffic is assigned to the best-effort forwarding class You have configured a CoS re-write rule on R1 to include the correct CoS bit values in packets sent towards R2 You want R2 to classify traffic using the CoS markings created by R1.

Which two configuration steps are necessary to accomplish this task? (Choose two.)

Options:

A.

Configure a CoS re-write rule on R2 and assign matching CoS values.

B.

Assign the CoS re-write rule to the ge-0/0/1.0 interface on R2.

C.

Assign the behavior aggregate classifier to the ge-0/0/1.0 interface on R2.

D.

Configure a behavior aggregate classifier on R2.

Question 2

Exhibit.

R2 has IS-IS adjacencies with R3 and R4 You want to ensure that R2 has both a level 1 and level 2 adjacency to both R3 and R4 but R2 only has one adjacency with R4.

Referring to the exhibit, which configuration change will solve this issue?

Options:

A.

Change the IS-IS area on R2 to match R4.

B.

Change the IS-IS area on R4 to match R2

C.

Remove the level 1 disable configuration from R4

D.

Remove the level 1 disable configuration from R2

Question 3

Click the Exhibit button.

A network administrator is investigating why traffic from R2 is not being forwarded to R1

Referring to the show isis database command output shown in the exhibit, what is causing this problem on the network?

Options:

A.

R1 and R2 are in different IS-IS areas.

B.

The preferred interface between R1 and R2 is experiencing errors

C.

R1 is configured to drop all incoming traffic.

D.

R2 is ignoring specific LSPs from R1 in its SPF calculations.

Question 4

Exhibit:

Referring to the ABR configuration shown in the exhibit, which three statements are correct? (Choose three.)

Options:

A.

The ABR advertises a default route to the NSSA using a Type 7 LSA.

B.

The ABR advertises a single Type 5 external LSA to the backbone area for all Type 7 LSAs in the NSSA.

C.

The ABR does not summarize any routes within the 192.168.16.0/20 range.

D.

The ABR advertises a Type 5 external LSA to the backbone area for each Type 7 LSA in the NSSA.

E.

The ABR advertises a single Type 3 summary LSA to the backbone area for all Type 1 and Type 2 LSAs in the 192.168.16 0/20 range.

Question 5

Exhibit:

You are troubleshooting an issue where R1 is no longer receiving the default IS-IS route from R3.

Referring to the exhibit, which action would you take to solve the problem?

Options:

A.

Delete the protocols isis ignore-attached-bit configuration statement on R3.

B.

Delete the protocols isis import configuration statement on R1.

C.

Delete the protocols isis level 2 disable configuration statement on R3.

D.

Delete the protocols isis ignore-attached-bit configuration statement on R1.

Question 6

You are creating a new LDP signaled Layer 2 circuit between three customer sites.

In this scenario, which two statements are correct? (Choose two.)

Options:

A.

LDP is used to exchange the virtual circuit labels with other PEs.

B.

You are allowed to tunnel your LDP sessions through RSVP LSPs.

C.

You are not allowed to use any RSVP-signaled LSPs in your core network.

D.

BGP is used to exchange the virtual circuit labels with other PEs.

Question 7

You are responsible for configuring CoS for your network Your network includes a video application with strict latency requirements, so that any packets delayed by more than 75 ms are effectively useless. You want to ensure that you do not waste buffer space.

When configuring the scheduler for this application, which feature would you use?

Options:

A.

exact

B.

remainder

C.

rate limit

D.

temporal

Question 8

Exhibit.

Referring to the exhibit, which statement is true?

Options:

B.

The BGP session between R1 and R2 will establish correctly and the met unicast and the met6 unicast NLRIs will pass routing information

C.

The BGP session between R1 and R2 will establish correctly and only the inet6 unicast NLRI will pass routing information

D.

The BGP session between R1 and R2 will establish correctly and only the met unicast NLRI will pass routing information

Question 9

The link between CE1 and PE1 has a history of flapping To avoid the impact that flapping causes to the network you decide to use route damping

Which statement is correct in this scenario?

Options:

A.

Dampened routes decay at a sliding rate known as half-life

B.

Routes become dampened when the configured max-suppress value is reached

C.

Dampening is enabled on interfaces

D.

Dampened routes become active when their figure of merit drops below the reuse value.

Question 10

Which two statements regarding ingress replication in EVPN are correct? (Choose two.)

Options:

B.

Ingress replication relies on PIM to build the multicast replication tree.

C.

Ingress replication labels are learned from remote PEs through the EVPN Type-3 route.

D.

Ingress replication is only supported in vrf-type routing instances.
