Metric is based on hop count.

B.

Slow convergence after link failures.

C.

Support hierarchy through the use of areas.

D.

Questions # 133:

If OSPF is used in a multi-area OSPF network, which of the following statements regarding route summarization is true?

Options:
A.

Manual route summarization can only be done on autonomous system border routers.

B.

Manual route summarization must be done on all the backbone routers to be effective. Manual route summarization is optional on the routers in non-backbone areas.

C.

Manual route summarization is done on the ABRs. By default, automatic summarization is done; however, it may not be optimal for all networks.

D.

Manual route summarization is done on the ABRs. By default, no route summarization is done and all routes are advertised to all areas.

D.

A value of 15.

Questions # 135:

From the list below select the statements that describe the behavior of link state information aging. (Choose 2)

A.

The age for newly created link state information is set to 0 for OSPF and 1200 for IS-IS

B.

The age for newly created link state information is set to 1200 for OSPF and 0 for IS-IS

C.

The age is incremented or decremented as it is flooded from router to router and as it is held in the topological database.

D.

The age is incremented or decremented only as it is held in the topological database and not as it is flooded router to router.

Standard Area

Questions # 139:

If two routers running IS-IS protocols are exchanging Hello packets with different authentication types, which of the following statements regarding the adjacency state established between them is true?

B.

An adjacency will not be formed

C.

The two routers negotiate the authentication type and then reach the up state.

B.

In multi-access networks, a DR and BDR are elected only if the subnet masks on the router interfaces are less than /30

C.

In multi-access networks, a DR and BDR are elected. To ensure resiliency, both the DR and BDR send link-state advertisements describing the network.

D.

In multi-access networks, a DR and BDR are elected. The DR sends link-state advertisements describing the network.
