Router R2 has two IS-IS adjacencies and two LSPs

B.

Router R2 has two IS-IS adjacencies and three LSPs

C.

Router R2 has two IS-IS adjacencies and four LSPs

D.

Router R2 has three IS-IS adjacencies and three LSPs

E.

Router R2 has three IS-IS adjacencies and four LSPs

F.

Router R2 has three IS-IS adjacencies and six LSPs

Which of the following is FALSE regarding link-state protocols?

A.

B.

When a router performs an SPF computation, it sends the results to its neighbors.

C.

An SPF computation is done by each router to determine the best path to destination prefixes

Type 1 Router LSA

B.

Type 2 Network LS A

Why would the neighbor do this?

A.

The neighbor's link-state database has newer information than what it received in the update.

B.

The neighbor sends the update as an acknowledgement.

C.

The neighbor's update indicates that it has run out of space in its LSDB.

D.

The neighbor's update indicates that the sequence number received is the same as the one already in its link-state database.

B.

An IS-IS router belongs to one or more areas.

C.

All Level 2 routers belong to the same area.

D.
