Chapter 5

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Which two statements describe the purpose of the EIGRP network command? (Choose two.)

Determines which networks are advertised within an EIGRP update across the network. *
Determines the type of network connection utilized across an interface.
Determines which networks belong to the EIGRP AS on the local router. *
Determines which EIGRP AS the local router is a member of.
Determines which metrics will be utilized to determine the best path.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
When would a router have a feasible successor identified in the topology table?

when a neighboring router that is currently being used for packet forwarding fails
when the feasible distance for the next hop router is less than the advertised distance to a router

when there is no successor listed or identified in the topology table
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Observe the configuration. RTA has two serial links and an Ethernet stub network of 3.1.0.0/16. Which command must the network administrator use to have EIGRP summarize the stub network at the classful boundary?

RTA(config-router)# no auto-summary
The network administrator does not have to issue a command. *
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
A network administrator wants to summarize the 192.168.64.0/19 network. Which of the following commands can be used to accomplish this?

Router(config)#router eigrp 101

Router(config)#interface s0/0
Router(config-if)# ip summary-address 192.168.64.0 255.255.224.0
Router(config)# router eigrp 101
Router(config-router)# ip summary-address eigrp 101 192.168.64.0 255.255.224.0

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Assuming that EIGRP is enabled on both routers, what must be configured to ensure that Router A will be able to reach the 2.2.2.0/24 network?

Use the command ip address-summary to ensure that Router A recognizes the 2.2.2.0 network.
EIGRP supports VLSM and will automatically recognize the 2.2.2.0 network.
EIGRP does not support VLSM, therefore cannot be used with discontiguous networks.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
What action does an EIGRP router take to find a feasible successor for a network?

It examines the routing and topology tables for a feasible successor.
It transitions from passive to active state for that network and queries its neighbors. *
It examines the routing and neighbor tables for a feasible successor.
It transitions from active to passive state for that network and queries its neighbors.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
What is the purpose of the eigrp log-neighbor-changes command?

Enables the logging of all EIGRP neighbor changes.
Enables the logging of EIGRP neighbor warning messages.
Enables the logging of EIGPR neighbor adjacency changes. *
Enables the logging of all EIGRP messages to the console.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Hello packets are used by EIGRP routers to perform which two tasks? (Choose two.)

rediscover routers that were previously unreachable *
maintain a topology table for each configured network protocol
choose the best route to a destination and place the route in the routing table
identify routers that have become either unreachable or inoperable *
send EIGRP packets that contain route tables
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
