Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) Questions and Answers

Question 21

A network operator working for a telecommunication company with an employee Id: 4065 96080 it trying to implement BFD configuration on an existing network of Cisco devices Which task must the engineer perform to enable BFD on the interfaces?

Options:

A.

Disable Cisco Express Forwarding on the interfaces

B.

Disable SSO on the interfaces

C.

Remove any static routes that point to the interfaces

D.

Remove the log option from any ACLs on the interfaces.

Question 22

A network engineer is configuring a newly installed PE router at the regional gateway location. The new PE router must use MPLS core routing protocols with the existing P router, and LDP sessions between the two routers must be protected to provide faster MPLS convergence. Which configuration must the engineer perform on the network so that LDP sessions are established?

Options:

A.

Enable communication over TCP port 646 for T-LDP hello messages.

B.

Enable RSVP-TE FRR on the LDP interface to protect the LDP session between routers.

C.

Enable LDP session protection on either one of the routers, which allows them to autonegotiate.

D.

Set the LDP session protection timer on each router to the same value.

Question 23

Refer to the exhibit. An engineer working for a private telecommunication company with an employee id: 3414:81:713 is implementing this network, in which:

Routers R1A and R1B are eBGP neighbors.

iBGP is configured within AS 65515 and AS 65516.

Network 192.168.2.0/24 is shared with AS 65516.

Router R3A has an iBGP relationship with router R2A only.

Router R2A has an iBGP relationship with routers R1A and R3A.

Which additional task must the engineer perform to complete the configuration?

Options:

A.

Configure router R2A to use the next-hop-self attribute when advertising the learned route to router R1A.

B.

Configure router R3A to redistribute route 192.168.2.0/24 into the configured IGP to advertise the prefix to router R1A.

C.

Configure router R2A as a route reflector to advertise the iBGP learned prefix from router R3A to R1A.

D.

Configure router R1A with a static route to 192.168.2.0/24 that is redistributed into BGP.

Question 24

An engineer must implement QoS to prioritize traffic that requires better service throughout the network. The engineer started by configuring a class map to identify the high-priority traffic. Which additional tasks must the engineer perform to implement the new QoS policy?

Options:

A.

Attach the class map to a policy map that sets the minimum bandwidth allocated to the classified traffic and designates the action to be taken on the traffic.

B.

Attach the class map to a policy map that designates the action to be taken on the classified traffic and then attach the policy map to an interface using a service policy.

C.

Attach the class map to a policy map within a VRF to segregate the high-priority traffic and then attach the policy map to an interface in another VRF.

D.

Create a route map to manipulate the routes that are entered into the routing table and then attach the route map to an interface using a service policy.
