A. Router R4 will have a default route with router R3 as the next-hop.

B. Router R4 will have a route to router R6's system IP address with router R2 as the next-hop.

C. Router R4 will not have a matching entry in its routing table for router R6's system IP address.

D. Router R4 will have a default route with router R2 as the next-hop.

문제3

Which of the following definitions best describes route redistribution?

A. It is the process of redirecting packets to be processed by an intermediate network function before allowing them to be forwarded to their intended final destination.

B. It is the process of controlling which route advertisements received from routing peers are accepted and/or deciding which locally known prefixes are advertised to routing peers.

C. It is the process of passing routing information from one routing domain to another, which usually means from one routing protocol to another.

D. It is the process of deciding at line-rate speed which packets will be dropped and which ones will be forwarded.

문제5

A router running a link-state routing protocol detects that one of its neighbors is no longer connected to it. The router generates a new link-state advertisement to inform other routers of the topology change. Which of the following is NOT an action that is triggered by this event?

A. If a router receives the new link-state advertisement, it acknowledges it, stores it, and forwards it to its own neighbors.

B. Every router that receives the new link-state advertisement updates its age field before forwarding it.

C. If a router receives multiple copies of the new link-state advertisement, it will simply ignore all copies received after the first one.

D. Every router that receives the new link-state advertisement runs the SPF algorithm to recalculate its shortest-path tree and its forwarding database.
