Questions and Answers
  • 1. 

    What are two characteristics of OSPF? (Choose two.) (Source: Implementing OSPF)

    • A.

      OSPF uses a two layer hierarchy.

    • B.

      OSPF is a proprietary routing protocol.

    • C.

      OSPF is an open standard.

    • D.

      OSPF is similar to the RIP routing protocol.

    • E.

      OSPF is a distance vector routing protocol.

    Correct Answer(s)
    A. OSPF uses a two layer hierarchy.
    C. OSPF is an open standard.
  • 2. 

    OSPF routes packets within a single _____. (Source: Implementing OSPF)

    • A.

      Area

    • B.

      Network

    • C.

      Segment

    • D.

      Autonomous system

    Correct Answer
    D. Autonomous system
    Explanation
    OSPF routes packets within a single autonomous system. An autonomous system (AS) is a collection of networks under a single administrative domain. OSPF is an interior gateway protocol (IGP) commonly used within an AS to exchange routing information and determine the best paths for packet forwarding. It enables routers within the same AS to communicate and exchange routing updates, allowing for efficient and reliable routing of packets within the network. Therefore, the correct answer is autonomous system.

    With OSPF, each router builds its SPF tree using the same link-state information, but each will have a separate _____ of the topology. (Source: Implementing OSPF)

    • A.

      State

    • B.

      View

    • C.

      Version

    • D.

      Configuration

    Correct Answer
    B. View
    Explanation
    In OSPF, each router builds its SPF tree using the same link-state information, but each router will have a separate view of the topology. This means that even though all routers have the same information about the network, they may have different perspectives or views of the network based on their own routing tables and calculations. Each router will create its own view of the network topology based on its own perspective and its own routing decisions.

  • 4. 

    Which component of the SPF algorithm is inversely proportional to bandwidth? (Source: Implementing OSPF)

    • A.

      Link cost

    • B.

      Root cost

    • C.

      Link state

    • D.

      Hop count

    Correct Answer
    A. Link cost
    Explanation
    The link cost in the SPF algorithm is inversely proportional to bandwidth. This means that as the bandwidth decreases, the link cost increases. The link cost is used to determine the best path for routing packets in OSPF, and a higher link cost indicates a less desirable path. Therefore, a lower bandwidth would result in a higher link cost, making it less likely for packets to be routed through that particular link.

  • 5. 

    Which command correctly starts an OSPF routing process using process ID 191? (Source: Implementing OSPF)

    • A.

      Router(config)#router ospf 191

    • B.

      Router(config)#network ospf 191

    • C.

      Router(config-router)#network ospf 191

    • D.

      Router(config-router)#router ospf process-id 191

    Correct Answer
    A. Router(config)#router ospf 191
    Explanation
    The correct answer is "Router(config)#router ospf 191". This command correctly starts an OSPF routing process using process ID 191. The "router ospf" command is used to enable OSPF routing on a router, and the process ID is specified after the command. In this case, the process ID is 191.

  • 6. 

    Q6) What is the purpose of the show ip ospf interface command? (Source: Implementing OSPF)

    • A.

      To display OSPF-related interface information

    • B.

      To display general information about OSPF routing processes

    • C.

      To display OSPF neighbor information on a per-interface basis

    • D.

      To display OSPF neighbor information on a per-interface type basis

    Correct Answer
    A. To display OSPF-related interface information
    Explanation
    The purpose of the "show ip ospf interface" command is to display OSPF-related interface information. This command provides details about the OSPF configuration and status on each interface, such as the interface IP address, OSPF area, network type, hello and dead intervals, and other relevant parameters. It helps administrators troubleshoot OSPF issues, verify interface settings, and ensure proper OSPF operation on each interface.

    Rate this question:

  • 7. 

    Which command output includes information about the length of the OSPF packet? (Source: Troubleshooting OSPF)

    • A.

      Debug ip ospf events

    • B.

      Debug ip ospf packet

    • C.

      Debug ip ospf packet size

    • D.

      Debug ip ospf mpls traffic-eng advertisements

    Correct Answer
    B. Debug ip ospf packet
    Explanation
    The command "debug ip ospf packet" includes information about the length of the OSPF packet. By enabling this debug command, the router will display detailed information about OSPF packets, including their size. This can be helpful for troubleshooting purposes, as it allows network administrators to analyze the size of OSPF packets and identify any potential issues related to packet size.

    Rate this question:

  • 8. 

    Which OSPF neighbor state indicates that two neighbors have exchanged routes?(Source: Troubleshooting OSPF)

    • A.

      Init

    • B.

      Two-way

    • C.

      Loading

    • D.

      Full

    Correct Answer
    D. Full
    Explanation
    The OSPF neighbor state "full" indicates that two neighbors have exchanged routes. In this state, the routers have established a fully adjacent relationship and are able to exchange routing information. This means that both routers have synchronized their link-state databases and are aware of each other's routes. This state is the final stage in the OSPF neighbor relationship, indicating a successful and complete exchange of routing information between the two routers.
