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

Question 53

Refer to the exhibit. Routers R1 through R5 are being deployed within the core of a service provider running BGP The core supports distribution of VPNv4 routes using MPLS. R3 currently has multiple paths to reach R4. A network engineer must implement BGP attributes so that R3 can reach R4 via R1. Which action must the engineer take to meet the requirement?

Options:

A.

Configure R3 so the route to R4 through R1 will have a higher weight than the route from R2 or R5.

B.

Configure R2 to send the route from R4 to R1 using a higher metric than what is advertised to R3.

C.

Configure R5 to send the route from R4 to R1 using a longer AS path than the AS path that it receives from R1 or R2.

D.

Configure R3 so the route to R4 through R1 will have a lower local preference than the route from R2 or R5

Question 54

Which task must be performed first to Implement BFD in an IS-IS environment?

Options:

A.

Disable Cisco Express Forward.ng on all interfaces running routing protocols other than IS-IS

B.

Configure BFD under the IS-IS process

C.

Configure all ISIS routers as Level 2 devices

D.

Configure BFD in an interface configuration mode

Question 55

An engineer Is implementing NSR with OSPF on a large campus that requires high availability. Which task must an engineer perform to complete the process with minimal disruption to traffic?

Options:

A.

Reset OSPF neighbor sessions to maintain state Information during router switchover

B.

Configure the device to repopulate state information using routing updates received from the BDR

C.

increase the keepalive interval on the OSPF neighbors so that traffic continues to pass during the switchover.

D.

Ensure that the dual RP has synchronized their state information before performing the switchover operation.

Question 56

FRR is configured on a network. What occurs when the headend router on the path is alerted to a link failure over IGP?

Options:

A.

LSP attempts fast switching on the backup path until the primary path returns to the active state.

B.

The headend router uses a presignaled LSP to bypass the failure point.

C.

A new backup tunnel is established past the PLR to pass through the protected nodes

D.
