Question 1

Which OSPF packet type is used to discover and maintain neighbor relationships?

Accepted Answer

Hello

Answer

OSPF Hello packets are sent periodically to discover neighbors and verify adjacency is maintained.

Question 2

A router has two routes to 192.168.10.0/24: one via OSPF with metric 20 and one via RIP with metric 5. Which route is installed in the routing table by default?

Accepted Answer

OSPF route, because OSPF has a lower AD of 110

Answer

Administrative Distance is compared before metric; OSPF AD 110 is lower than RIP AD 120, so the OSPF route wins.

Question 3

What is the default OSPF hello interval on a broadcast multi-access network?

Accepted Answer

10 seconds

Answer

The default OSPF Hello interval on broadcast and point-to-point links is 10 seconds.

Question 4

Which command enables OSPF process 1 and places interface 192.168.1.0/24 into area 0?

Accepted Answer

router ospf 1 / network 192.168.1.0 0.0.0.255 area 0

Answer

The network command under OSPF uses a wildcard mask, not a subnet mask, followed by the area number.

Question 5

What does the EIGRP term 'feasible successor' refer to?

Accepted Answer

A backup route that meets the feasibility condition

Answer

A feasible successor is a backup path whose reported distance is less than the successor's feasible distance, stored in the topology table.
