ICND1 Routing Technologies & Protocols 3

Question 1

Which EIGRP metric components are used by default?

Accepted Answer

Bandwidth and delay

Answer

By default, EIGRP uses only bandwidth and delay (K1 and K3) in its composite metric calculation.

Question 2

What is the maximum hop count supported by RIPv2?

Accepted Answer

15

Answer

RIPv2 supports a maximum hop count of 15; a hop count of 16 is considered unreachable.

Question 3

Which command verifies the OSPF neighbor state on a Cisco router?

Accepted Answer

show ip ospf neighbor

Answer

The 'show ip ospf neighbor' command displays OSPF neighbor relationships and their current state.

Question 4

In OSPF, which router is elected as the Designated Router (DR) on a multi-access segment?

Accepted Answer

The router with the highest router-ID and priority greater than 0

Answer

The DR is elected based on the highest OSPF priority, with the router-ID as a tiebreaker; a priority of 0 disqualifies a router.

Question 5

A network administrator adds 'passive-interface GigabitEthernet0/1' under RIP. What is the effect?

Accepted Answer

RIP updates are received but not sent on Gi0/1

Answer

A passive interface suppresses RIP update transmission but still processes received updates and advertises the connected network.
