    Name and surname: ________________________________

    1. Which two statements are true regarding link-state routing protocols? (Choose two.)

    a. They do not work well in networks that require special hierarchical designs.

    b. They are aware of the complete network topology.c. They pass their entire routing tables to their directly connected neighbors only.d. They offer rapid convergence times in large networks.e. They rely on decreasing hop counts to determine the best path.f. They do not include subnet masks in their routing updates.

    2. Which three statements about routing protocols are true? (Choose three.)

    a. OSPF elects designated routers on multiaccess links.b. RIP does not support classless routing.c. EIGRP supports unequal cost load balancing.

    d. EIGRP uses broadcast traffic to establish adjacencies with its neighbors.e. RIP does not advertise a route beyond a hop count of 15.f. OSPF can convergence more quickly because it can find a feasible successor in its topology tablewhen a successor route goes down.

    3. What does RIP use to reduce convergence time in a larger network?

    a. It reduces the update timer to 15 seconds if there are more then 10 routes.b. It uses triggered updates to announce network changes if they happen in between the periodicupdates.c. It uses random pings to detect if a pathway is down and therefore is preemptive on finding

    networks that are down.d. It uses multicast instead of broadcast to send routing updates.

    4.Refer to the exhibit. The network administrator issues the command no ip classless on Router1.What forwarding action will take place on a packet that is received by Router1 and is destined for host192.168.0.26?

    a. The packet will be dropped.

    b. The packet will be forwarded to the gateway of last resort.c. The packet will match the 192.168.0.0 network and be forwarded out Serial 0/0.d. The packet will most closely match the 192.168.0.8 subnet and be forwarded out Serial 0/1

    5. Refer to the exhibit. Router R1 is configured as shown in the exhibit. PC1 on 172.16.1.0/24network can reach the default gateway on R1. The rest of the routers are configured with the correct
