Cisco CCNA Static and Dynamic Routing 2

Question 1

A router has two routes to 192.168.10.0/24: one via OSPF with metric 20 and one via EIGRP with metric 100. Which route is installed in the routing table by default?

Accepted Answer

The EIGRP route because EIGRP has a lower administrative distance of 90

Answer

EIGRP has an administrative distance of 90, which is lower than OSPF's 110, so the EIGRP route is preferred regardless of metric.

Question 2

Which command configures a default static route on a Cisco router pointing to next-hop 10.0.0.1?

Accepted Answer

ip route 0.0.0.0 0.0.0.0 10.0.0.1

Answer

The correct syntax for a default static route uses network 0.0.0.0 with wildcard mask 0.0.0.0 followed by the next-hop address.

Question 3

What is the purpose of the EIGRP feasibility condition?

Accepted Answer

It guarantees a backup route is loop-free by requiring the feasible successor's RD to be less than the successor's FD

Answer

The feasibility condition confirms a feasible successor is loop-free by checking that its reported distance is less than the current successor's feasible distance.

Question 4

A floating static route is configured with administrative distance 200. Under what condition will this route appear in the routing table?

Accepted Answer

Only when the primary dynamic route from a protocol with AD less than 200 is lost

Answer

A floating static route with a higher AD than the dynamic protocol stays hidden until the dynamic route disappears, then it activates as a backup.

Question 5

Which OSPF network type sends Hello packets every 10 seconds and has a dead interval of 40 seconds by default?

Accepted Answer

Broadcast and point-to-point

Answer

OSPF broadcast and point-to-point network types use a 10-second Hello interval and 40-second dead interval by default.
