What are reasons for creating OSPF in a hierarchical design?
1. To decrease routing overhead
2. To speed up convergence
3. To confine network instability to single areas of the network
4. To make configuring OSPF easier -
Which two of the following commands will place network 10.2.3.0/24 into area 0?
1. router eigrp 10
2. router ospf 10
3. network 10.0.0.0
4. network 10.2.3.0 0.0.0.255 area0
5. network 10.2.3.0 0.0.0.255 area 0 - If routers in a single area are configured with the same priority value, what value does a router use for the OSPF Router ID in the absence of a loopback interface?
-
Which of the following protocols support VLSM, summarization, and discontiguous networking?
1. RIPv1
2. IGRP
3. EIGRP
4. OSPF
5. BGP
6. RIPv2 -
You get a call from a network administrator who tells you that he typed the following into his router:
Router (config) #router ospf 1
Router (config-router) #network 10.0.0.0 255.0.0.0 area 0
He tells you he still can't see any routes in the routing table. What configuration error did the administrator make?

Which of the following network types have a designated router and a backup designated router assigned?
1. Broadcast
2. Point-to-point
3. NBMA
4. NBMA point-to-point -
Which type of OSPF network will elect a backup designated router?
1. Broadcast multi-access
2. Non-broadcast multi-access
3. Point-to-point
4. Broadcast multipoint - You need the IP address of the devices with which the router has established an adjacency. Also, the retransmit interval and the queue counts for the adjacent routers need to be checked. What command will display the required information?
