Question No. 3

A static route is created using the command "static-route 2.3.4.0/24 next-hop 1.2.3.4". What is the correct traceroute command to test this static route on an Nokia 7750 SR?

Atraceroute 2.3.4.1

Btraceroute 2.3.4.0/24 next-hop 1.2.3.4

Ctraceroute next-hop 1.2.3.4

Dtraceroute does not work on the Nokia 7750 SR

What triggers convergence of the routing protocol when the link between switch 1 and switch 2 goes down?

AConvergence is triggered when the adjacency between routers R1 and R2 drops as a result of Hello timeouts. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

BConvergence is triggered when the physical interfaces between routers R1 and R2 go down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

CConvergence will not be triggered because switches cannot run routing protocols between them.

DConvergence is triggered when the switches notify the routers about the link state information. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged

EConvergence is triggered when an LSA is sent from router R1 to router R2 to indicate that the link is down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

Correct Answer: A

Question No. 5

Which of the following regarding BGP Path Identifier is FALSE?

APath-ID is a four-octet identifier pre-pended to the NLRI field of a BGP update.

BPath-ID is an optional transitive attribute used to advertise multiple paths.

CPath-ID uniquely identifies each path advertised to a neighbor.

DA BGP speaker that re-advertises a route must generate its own Path-ID.
