    What is the default administrative distance of EIGRP internal routes?

    • 70

    • 90

    • 110

    • 120

    • 255

    Correct Answer
    A. 90
    Explanation
    The default administrative distance of EIGRP internal routes is 90. Administrative distance is a metric used by routers to determine the trustworthiness of routing information received from different routing protocols. A lower administrative distance value indicates a higher priority for the routing protocol. In the case of EIGRP, the default administrative distance for internal routes is set to 90, which means that EIGRP routes are given higher priority compared to routes from other routing protocols with higher administrative distances.

    Which of the following router commands is recommended only for troubleshooting specific types of network problems, not for monitoring normal network operation?  

    • Show

    • List

    • Debug

    • Terminal monitor

    Correct Answer
    A. Debug
    Explanation
    The "debug" command is recommended only for troubleshooting specific types of network problems, not for monitoring normal network operation. This command enables the router to display detailed information about the internal operations and processes, which can be useful for diagnosing issues but can also generate a large amount of output and potentially impact the performance of the router. Therefore, it is not recommended for continuous monitoring of the network.

    Which Layer 4 protocol does EIGRP use to provide reliability for the transmission of routing information?

    • DUAL

    • IP

    • RTP

    • TCP

    • UDP

    Correct Answer
    A. RTP
    Explanation
    EIGRP uses the Real-Time Transport Protocol (RTP) to provide reliability for the transmission of routing information. RTP is a Layer 4 protocol that is commonly used for real-time multimedia applications, but in the case of EIGRP, it is utilized to ensure the reliable delivery of routing updates between EIGRP routers. RTP provides features such as sequence numbering, time-stamping, and error detection, which help to ensure the accurate and timely delivery of routing information.

    Which command will display only the current EIGRP routing table entries?

    • Router# show ip route

    • Router# show ip route eigrp

    • Router# show eigrp route

    • Router# show eigrp protocol

    Correct Answer
    A. Router# show ip route eigrp
    Explanation
    The correct answer is "Router# show ip route eigrp". This command specifically displays only the current EIGRP routing table entries. The "show ip route" command displays the entire IP routing table, while the "show eigrp route" command does not exist and the "show eigrp protocol" command displays information about the EIGRP protocol.

    Host 192.168.1.66 in the network illustrated is unable to ping host 192.168.1.130. How must EIGRP be configured to enable connectivity between the two hosts? (Choose two.) - ProProfs

    Host 192.168.1.66 in the network illustrated is unable to ping host 192.168.1.130. How must EIGRP be configured to enable connectivity between the two hosts? (Choose two.)

    • R1(config-router)# network 192.168.1.128

    • R1(config-router)# auto-summary

    • R1(config-router)# no auto-summary

    • R2(config-router)# no auto-summary

    • R2(config-router)# auto-summary

    Correct Answer(s)
    A. R1(config-router)# no auto-summary
    A. R2(config-router)# no auto-summary
    Explanation
    The correct answer is R1(config-router)# no auto-summary, R2(config-router)# no auto-summary. The "no auto-summary" command is used to disable automatic summarization in EIGRP. By default, EIGRP automatically summarizes routes at network boundaries, which can cause connectivity issues between hosts in the same network. Disabling auto-summary ensures that EIGRP advertises the specific subnets, allowing for proper routing and connectivity between the two hosts.

    Rate this question:

  • 7. 

    What tables does EIGRP maintain for each routed protocol it supports? (Choose three.)

    • Adjacency table

    • Topology table

    • Neighbor table

    • Routing table

    • ARP table

    Correct Answer(s)
    A. Topology table
    A. Neighbor table
    A. Routing table
    Explanation
    EIGRP maintains three tables for each routed protocol it supports. The topology table stores information about all the routes learned from neighboring routers. The neighbor table keeps track of all the neighboring routers with which EIGRP has formed an adjacency. The routing table contains the best routes selected from the topology table and is used for forwarding packets. The ARP table, which is not maintained by EIGRP, is used to map IP addresses to MAC addresses in order to communicate on a local network.

    Rate this question:

  • 8. 

    Which EIGRP command is used to view all routes that are known by the router?

    • Show ip eigrp interfaces detail

    • Show ip eigrp traffic

    • Show ip eigrp neighbors

    • Show ip eigrp topology all-links

    Correct Answer
    A. Show ip eigrp topology all-links
    Explanation
    The command "show ip eigrp topology all-links" is used to view all routes that are known by the router. This command displays detailed information about the EIGRP topology table, including all the routes and their associated metrics. It provides a comprehensive view of the network's routing table, allowing administrators to analyze and troubleshoot the EIGRP routing protocol.

    Rate this question:

  • 9. 

    Which of the following statements describes the bounded updates used by EIGRP?

    • Bounded updates are sent to all routers within an autonomous system.

    • Partial updates are sent only to routers that need the information.

    • The updates are sent to all routers in the routing table.

    • Updates are bounded by the routers in the topology table.

    Correct Answer
    A. Partial updates are sent only to routers that need the information.
    Explanation
    Bounded updates in EIGRP refer to the process of sending updates only to routers that require the specific information being updated. This approach helps to minimize unnecessary network traffic by avoiding the transmission of updates to routers that do not need them. Instead, EIGRP selectively sends partial updates to the routers that require the updated information, ensuring efficient and targeted communication within the network.

    Rate this question:

  • 10. 

    In which of the following tables does the EIGRP DUAL algorithm store the primary route to a destination? (Choose two.)

    • Routing

    • Topology

    • Neighbor

    • Path

    • Shortest path

    Correct Answer(s)
    A. Routing
    A. Topology
    Explanation
    The EIGRP DUAL algorithm stores the primary route to a destination in the routing and topology tables. The routing table contains the best routes to reach different destinations, while the topology table maintains information about all routes learned from neighboring routers. By storing the primary route in both tables, EIGRP ensures redundancy and allows for quick convergence in case of network changes or failures.

  • 11. 

    What is the advantage of routers forming adjacencies when using EIGRP? (Choose three.)  

    • Neighbor routers can quickly take over for a router that is in passive mode.

    • New routers and their routes can quickly be discovered by neighbor routers.

    • A router can share routing loads with neighbor routers.

    • A router can quickly discover when a neighbor router is no longer available.

    • Changes in network topology can quickly be shared with neighbor routers.

    Correct Answer(s)
    A. New routers and their routes can quickly be discovered by neighbor routers.
    A. A router can quickly discover when a neighbor router is no longer available.
    A. Changes in network topology can quickly be shared with neighbor routers.
    Explanation
    The advantage of routers forming adjacencies when using EIGRP is that new routers and their routes can quickly be discovered by neighbor routers. This allows for efficient and timely updates to the routing tables, ensuring that the network is aware of any new routers and their available routes. Additionally, a router can quickly discover when a neighbor router is no longer available, allowing for immediate rerouting and ensuring network reliability. Lastly, changes in network topology can quickly be shared with neighbor routers, allowing for dynamic adaptation to any changes in the network.

  • 12. 

    Why would it be necessary to configure the bandwidth setting on an EIGRP interface rather than leaving it at the default setting? (Choose two.)

    • A suboptimal route may be chosen as the best path to a destination if the bandwidth setting is higher than the actual bandwidth of the link.

    • The network may be unable to converge if the bandwidth setting does not match the actual bandwidth of the link.

    • Routing updates might arrive too fast for the interface to handle and be discarded because of buffer overflow.

    • The configured bandwidth must match the actual speed of the link so the link will operate properly.

    • Setting the bandwidth to a higher rate will optimize the effective throughput of the link.

    Correct Answer(s)
    A. A suboptimal route may be chosen as the best path to a destination if the bandwidth setting is higher than the actual bandwidth of the link.
    A. The network may be unable to converge if the bandwidth setting does not match the actual bandwidth of the link.
    Explanation
    The first reason for configuring the bandwidth setting on an EIGRP interface is that if the bandwidth setting is higher than the actual bandwidth of the link, a suboptimal route may be chosen as the best path to a destination. This can result in inefficient routing and slower network performance. The second reason is that if the bandwidth setting does not match the actual bandwidth of the link, the network may be unable to converge. This means that the routing tables may not be properly updated, leading to potential routing issues and network instability.

    Rate this question:

  • 13. 

    Which of the following are found in the EIGRP neighbor table? (Choose two.)

    • Routes installed by DUAL

    • Lowest calculated metric to each destination

    • Network layer address of the neighbor routers

    • Number of EIGRP packets waiting to be sent

    • Feasible distance to each neighbor

    Correct Answer(s)
    A. Network layer address of the neighbor routers
    A. Number of EIGRP packets waiting to be sent
    Explanation
    The EIGRP neighbor table contains the network layer address of the neighbor routers, which is important for establishing and maintaining neighbor relationships. It also includes the number of EIGRP packets waiting to be sent, which helps in monitoring the status and congestion of the network. The other options mentioned, such as routes installed by DUAL, lowest calculated metric to each destination, and feasible distance to each neighbor, are not part of the EIGRP neighbor table.

    Rate this question:

  • 14. 

    What information is maintained in the EIGRP topology database for a destination route? (Choose three.)

    • The routing protocol

    • The feasible distance of the route

    • The highest cost of the route

    • The route cost as advertised by the neighboring router

    • The physical address of the gateway interface

    Correct Answer(s)
    A. The feasible distance of the route
    A. The route cost as advertised by the neighboring router
    Explanation
    The EIGRP topology database maintains information about the feasible distance of the route, which is the total metric calculated by EIGRP for a particular route. It also keeps track of the route cost as advertised by the neighboring router, which is the metric value advertised by the router that is directly connected to the destination network. The physical address of the gateway interface is not maintained in the EIGRP topology database.
