Eigrp And Ospf

A network administrator needs to configure a router with a distance-vector protocol that allows classless routing. Which of the following satisfies those requirements?

A:

IGRP

B:

OSPF

C:

RIPv1

D:

EIGRP

Answer: D

In this question, we're calling EIGRP just plain old distance vector. EIGRP is an "advanced" distance-vector routing protocol, sometimes called a hybrid routing protocol because it uses the characteristics of both distance-vector and link-state routing protocols.

Which of the following describe the process identifier that is used to run OSPF on a router?

It is locally significant.
It is globally significant.
It is needed to identify a unique instance of an OSPF database.
It is an optional parameter required only if multiple OSPF processes are running on the router.

A:

1, 2 and 4

B:

1 and 3

C:

3 and 5

D:

All of the above

Answer: B

The Process ID for OSPF on a router is only locally significant and you can use the same number on each router, or each router can have a different number-it just doesn't matter. The numbers you can use are from 1 to 65,535. Don't get this confused with area numbers, which can be from 0 to 4.2 billion.

With which network type will OSPF establish router adjacencies but not perform the DR/BDR election process?

A:

Point-to-point

B:

Backbone area 0

C:

Broadcast multi-access

D:

Non-broadcast multi-access

Answer: A

No DR is assigned on any type of point-to-point link. No DR/BDR is assigned on the NBMA point-to-multipoint due to the hub/spoke topology. DR and BDR are elected on broadcast and non-broadcast multi-access networks. Frame Relay is a non-broadcast multi-access (NBMA) network by default.
