CCNA3 MODULE 1

True or False? In the router ospf process-id command, the process ID value, which can any number between 1 and 65,535, is locally significant. It must be the same on all routers in the OSPF area.

• T

• F

Which of the following applies to the router ID? (Choose two)

• The router ID cannot be defined by an administrator.

• The router ID is not used to determine the BDR.

• The router ID is used to determine the DR.

• The router ID uniquely identifies the router.

• router.

  The router ID is not required.

Which of the following is the order of precedence for choosing the router ID?

• 1. Router ID that is explicitly configured
  2. Lowest IPv4 loopback address
  3. Lowest active configured IPv4 address

• 1. Router ID that is explicitly configured
  2. Lowest active configured IPv4 address
  3. Lowest IPv4 loopback address

• 1. Router ID that is explicitly configured
  2. Highest IPv4 loopback address
  3. Highest active configured IPv4 address

• 1. Highest IPv4 loopback address
  2. Router ID that is explicitly configured
  3. Highest active configured IPv4 address

• 1. Highest IPv4 loopback address
  2. Highest active configured IPv4 address
  3. Router ID that is explicitly configured

Which criterion is preferred by the router to choose a router ID?

• The IP Address of the highest configured loopback on the router

• The IP address of the highest active interface on the router

• The router-id rid command

• The IP address of the highest activite OSPF-enabled interface

Which wildcard mask would be used to advertise the 192.168.5.96/27 network as part of an OSPF configuration?

• 255.255.255.253

• 255.255.255.224

• 0.0.0.32

• 0.0.0.31

The following three networks are directly connected to an OSPF router; 192.168.0.0/24, 192.168.1.0/24, and 192.168.2.0/24. Which OSPF network command would advertise only the 192.168.1.0 network to neighbors?

• Router(config-router)#network 192.168.1.0.0.0.0.255 area 0

• Router(config-router)#network 192.168.1.0.0.0.0.0 area 0

• Router(config-router)#network 192.168.1.0.0.0.15.255 area 0

• Router(config-router)#network 192.168.1.0. 255.255.255 area 0?

Which three parameters should match in order for a pair of routers to form an adjacency when running OSPFv2? (Choose three)

• interface priority

• Subnet mask

• Router ID

• Hello timer

• OSPF v2 type of network

What are two features of the OSPF routing protocol? (Choose two)

• Has an administrative distance of 100

• Uses Djkstra's Algorithm to build the SPF tree

• Calculate its metric using bandwidth

• Automatically summarizes networks at the classful boundaries

• Used primarily as an EGP

A router with two LAN interfaces, two WAN interfaces, and one configured loopback interface is operating with OSPF as its routing protocol. What does the router OSPF process use to assign the router ID?

• The loopback interface IP address

• The highest IP Address on the LAN interface

• The highest IP address that is configured on the WAN interfaces

• The OSPF area ID that is configured on the interface with the highest IP address

• The IP address of the interface that is configured with priority 0

Which verification command would identify the specific interfaces on a router that were configured with the passive-interface command? show ip route eigrp, show ip interface brief, show ip protocols or show ip eigrp neighbors?

• show ip route eigrp

• show ip interface brief

• show ip protocols

• show ip eigrp neighbors?
