All routers are using RIPv2. At what stage will this network converge, after the routers start up?

A. Initial network discoveryB. First exchange of routing informationC. Second exchange of routing informationD. Third exchange of routing informationE. Later than that

Which feature is most important when selecting a routing protocol for a large network?

A. Convergence TimeB. ScalabilityC. VLSM supportD. Resource usageE. Administrator knowledge requirements

Which feature determines the duration of routing loops?

A. Convergence TimeB. ScalabilityC. VLSM supportD. Resource usageE. Administrator knowledge requirements

Which of these is not a distance-vector routing protocol?

A. OSPFB. EIGRPC. RIPD. IGRPE. More than one of the above

Which timer determines when an old route is removed from the routing table?

A. Update timerB. Invalid timerC. Flush timerD. Holddown timerE. None of the above

Which routing protocol does not send periodic updates?

A. RIPB. RIPv2C. EIGRPD. IGRPE. None of the above

How many of these items are used by RIP? Invalid timerFlush timerHolddown timerTriggered updates

A. 0B. 1C. 2D. 3E. 4

S3 goes down. After that, R2 and R3 exchange many updates changing the metric for the route to PC3. Which term describes this problem?

S3 goes down. Which technique will most rapidly stop all routers sending packets to S3?

A. Count to infinityB. Split horizonC. Route poisoningD. Periodic updatesE. The question cannot be answered from the
