    1. IS-IS stands for:

    Interconnection System to Interconnection System
    Interconnection System to Intermediate System
    Intermediate System to Interconnection System
    Intermediate System to Intermediate System

    2. Which of the following are features common to both OSPF and IS-IS? )Choose two)

    They both use areas
    They are both classful protocols
    They both use the DUAL algorithm
    They both have authentication capabilities
    They both use Area Border Routers (ABRs) on borders between areas

    3. Which of the following are analogous or comparable to OSPF Area Border Routers (ABRs)?

    L1
    L2
    L1/L2
    L0

    4. Which of the following statements are true? (Choose two)

    Level 1 intermediate systems (routers) connect areas
    Level 2 intermediate systems (routers) connect areas
    An intermediate system can either be a Level 1 router (L1) or a Level 2 router (L2), but not both (L1/L2)
    An intermediate system can be a Level 1 router (L1), a Level 2 router (L2), or both (L1/L2)

    5. What is true regarding physical and logical interfaces?

    Logical interfaces are only up when interesting traffic is present
    Logical interfaces better handle split horizon issues over NBMA
    Logical interfaces can be split into multiple physical interfaces
    Logical interfaces are more reliable because they are always up

    6. What is true regarding communities?

    It specifies the autonomous system and the router that has generated an aggregate
    A degree of preference is given to a route to compare it with other routes for the same destination
    It gives a hint to external neighbors about the preferred path into an AS that has multiple entry points
    It can be configured at the AS level

    7. What are three characteristics of a BGP community?

    It is not restricted to an AS or network
    It specifies the autonomous system and the router that has generated an aggregate
    It filters traffic in and out
    A degree of preference given to a route to compare it with other routes for the same destination
    It gives a hint to external neighbors about the preferred path into an AS that has multiple entry points
    It is used in redistribution

    8. What are three EIGRP reliable packets?

    Query
    Update
    Hello
    Reply
    SYN Access
    Broadcast
    ACK

    9. What does EIGRP use to find other routers?

    Unicasts
    Multicasts
    Broadcasts
    All-nodes unicast
    Summary Broadcasts

    10. Which of the following will NOT allow EIGRP to form neighbor/peer relationships? (Choose three)

    Secondary addresses
    Mismatched hello intervals
    Different autonomous systems
    Mismatched hold time values
    Misaligned K-values
