CCNA 3 v6.0 (Scaling Networks v6) Chapter 6: EIGRP: Check Your Understanding Questions Answers
1. What is the purpose of using protocol-dependent modules in EIGRP?
- To accommodate routing of different network layer protocols
- To describe different routing processes
- To identify different application layer protocols
- To use different transport protocols for different packets
2. If all router Ethernet interfaces in an EIGRP network are configured with the default EIGRP timers, how long will a router wait by default to receive an EIGRP packet from its neighbor before declaring the neighbor unreachable?
- 5 seconds
- 10 seconds
- 15 seconds
- 30 seconds
3. Which two EIGRP packet types are sent with unreliable delivery? (Choose two.)
- Acknowledgment packet
- Hello packet
- Query packet
- Reply packet
- Update packet
4. Which destination MAC address is used when a multicast EIGRP packet is encapsulated into an Ethernet frame?
5. What is identified within the opcode of an EIGRP packet header?
- The EIGRP autonomous system metrics
- The EIGRP hold timer agreed upon with a neighbor
- The EIGRP message type that is being sent to or received from a neighbor
- The EIGRP sum of delays from source to destination
6. Why would a network administrator use a wildcard mask in the network command when configuring a router to use EIGRP?
- To exclude some interfaces from the EIGRP process
- To reduce the router overhead
- To send a manual summarization
- To subnet at the time of the configuration
7. An administrator issues the router eigrp 100 command on a router. What is the number 100 used for?
- As the autonomous system number
- As the length of time this router will wait to hear Hello packets from a neighbor
- As the maximum bandwidth of the fastest interface on the router
- As the number of neighbors supported by this router
8. What information does EIGRP maintain within the routing table?
- Adjacent neighbors
- All routes known to the router
- Both successors and feasible successors
- Only feasible successors
- Only successors
9. Which table does EIGRP use to store all routes that are learned from EIGRP neighbors?
- The adjacency table
- The neighbor table
- The routing table
- The topology table
10. Which command is used to display the bandwidth of an interface on an EIGRP-enabled router?
- show ip route
- show interfaces
- show ip interface brief
- show ip protocols
11. A new network administrator has been asked to verify the metrics that are used by EIGRP on a Cisco device. Which two EIGRP metrics are measured by using static values on a Cisco device? (Choose two.)
12. How do EIGRP routers establish and maintain neighbor adjacencies?
- By comparing known routes to information received in updates
- By dynamically learning new routes from neighbors
- By exchanging Hello packets with neighboring routers
- By exchanging neighbor tables with directly attached routers
- By exchanging routing tables with directly attached routers
13. What is indicated when an EIGRP route is in the passive state?
- The route has the highest path cost of all routes to that destination network.
- The route is a feasible successor and will be used if the active route fails.
- The route is viable and can be used to forward traffic.
- The route must be confirmed by neighboring routers before it is put in the active state.
- There is no activity on the route to that network.
14. What is the multicast address used by an EIGRP-enabled router operating with IPv6?
15. Which configuration is necessary to ensure successful operation of EIGRP for IPv6?
- The eigrp router-id command requires an IPv6 address in the router configuration mode.
- The network command is required in the router configuration mode.
- The no shutdown command is required in the router configuration mode.
- The router eigrp autonomous-system command is required in the router configuration mode.
