Question 1

Which statement correctly describes the difference between a routing protocol and a routed protocol?

Accepted Answer

A routed protocol carries user data while a routing protocol builds and maintains the routing table

Answer

Routed protocols like IP carry user traffic, while routing protocols like OSPF or EIGRP exchange routing information to populate the routing table.

Question 2

An OSPF router is in the 'Exstart' state. What is occurring at this stage?

Accepted Answer

Routers are electing the master/slave relationship and establishing the initial DBD sequence number

Answer

In the Exstart state, OSPF neighbors determine master/slave roles and agree on the initial Database Description sequence number before exchanging LSAs.

Question 3

What happens to EIGRP routes when the variance command is set to 2?

Accepted Answer

Routes with a metric up to twice the successor's FD are eligible for unequal-cost load balancing

Answer

Setting variance to 2 allows EIGRP to install feasible successor routes whose FD is up to 2x the successor's FD for unequal-cost load balancing.

Question 4

Which command would you use to verify the OSPF neighbor state on a Cisco router?

Accepted Answer

show ip ospf neighbor

Answer

The 'show ip ospf neighbor' command displays the neighbor ID, priority, state, dead time, address, and interface for all OSPF adjacencies.

Question 5

A router running RIPv2 receives an update with a hop count of 16 for a destination network. What does the router do with this route?

Accepted Answer

Considers the route unreachable and does not install it

Answer

In RIP, a hop count of 16 means infinity (unreachable), so the router treats the route as invalid and removes or ignores it.
