  Which of the following is FALSE?

  A. The router can reach prefix 192.10.1.2/32 through a RSVP-TE tunnel.
  B. The router can reach prefix 192.10.1.2/32 through an LDP tunnel.
  C. The router 10.10.10.2 is the egress router of the prefix 192.10.1.2/32.
  D. The Isp-ping tool is used to perform a unidirectional LSP test.

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

  A. Convergence 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.
  B. Convergence 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.
  C. Convergence will not be triggered because switches cannot run routing protocols between them.
  D. Convergence 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
  E. Convergence 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.

• Question 178:

  B. config>router>bgp= confederation 65200 members 65202
  C. config>router= confederation 65202 members 65200
  D. config>router>bgp= confederation 65202 members 65200
  A. config>router- confederation 65200 members 65202

• Question 179:

  Which of the following regarding per-platform label space is TRUE?

  B. A single label is assigned to a FEC for all interfaces on the same router,
  C. It is typically used when the device has ATM or Frame Relay interfaces.
  D. It uses more label resources than a per-interface label space.
  B. A single label is assigned to a FEC for all interfaces on the same router,
