Which of the following statements describe the network shown in the graphic? (Choose two.)
A.
There are two broadcast domains in the network.
B.
There are four broadcast domains in the network.
C.
There are six broadcast domains in the network.
D.
There are four collision domains in the network.
E.
There are five collision domains in the network.
F.
There are seven collision domains in the network.
Explanation:
Only router can break up broadcast domains so in the exhibit there are 2 broadcast domains: from
e0 interface to the left is a broadcast domain and from e1 interface to the right is another
broadcast domain ->.
Both router and switch can break up collision domains so there is only 1 collision domain on the
left of the router (because hub doesn’t break up collision domain) and there are 6 collision
domains on the right of the router (1 collision domain from e1 interface to the switch + 5 collision
domains for 5 PCs in Production) ->
Each of routers running link-state routing protocol learns paths to all the destinations in its “area” so we can say A is correct although it is a bit unclear.
Link-state routing protocols generate routing updates only (not the whole routing table) when a change occurs in the network topology so B is not correct.
Link-state routing protocol like OSPF uses Dijkstra algorithm to calculate the shortest path -> C is correct.
Unlike Distance vector routing protocol (which utilizes frequent periodic updates), link-state routing protocol utilizes event-triggered updates (only sends update when a change occurs) -> D is correct but E is not correct.
