Question # 17

A router is configured with the command "configure router ecmp 4". There are two best paths to a given destination with an equal cost in the IGP. Which of the following best describes the handling of traffic to this destination?

The router installs two routes for the destination with two different next hops. A hashing algorithm is used to distribute traffic over the two paths.

The router installs two routes for the destination with two different next hops. Traffic is evenly distributed over the two paths.

The router installs four routes for the destination with four different next hops. A hashing algorithm is used to distribute traffic over the four paths.

The router installs four routes for the destination with four different next hops. Traffic is evenly distributed over the four paths.

The router installs one route for the destination. Traffic is evenly distributed over the two paths.

Question # 22

Link-state PDUs include an age field. Which of the following is FALSE?

When link-state information reaches the maximum age on a router, the router will flood that information to its neighbors.

When a router detects that any of its link-state information has reached the maximum age, it will request a new update from the source router.

Aging helps ensure that links, which are no longer part of the topology, will eventually get removed from the LSDB.

The age value is updated as the information is flooded throughout the network and when it is in the LSDB.

Router R5 is advertising the three loopbacks prefixes shown in OSPFv3. The following command is executed on router R1: R1# configure router ospf3 area 0 area-range FD00:11:11:5000:764.

Which of the following is TRUE regarding the OSPFv3 LSDB on R6?

Router R6 will have a single Router LSA that describes the summary prefix.

Router R6 will have three Router LSAs - one to describe each loopback prefix.

Router R6 will have a single Inter-Area Prefix LSA to describe the summary prefix.

Router R6 will have three Inter-Area Prefix LSAs - one to describe each loopback prefix.

Router R6 will not have any LSAs to describe the loopback prefix or the summarized prefix.
