Module 13 Exam Back to Main Page 1. When a router receives a frame, it first checks the ___ field. If there is an error found there is no point in moving to the next step, so the packet is discarded.FCSdestinationsourceCRCQuestion 1 of 19 2. Before forwarding a frame the TTL field must then be incremented and a new header checksum calculated.TrueFalseQuestion 2 of 19 3. The routing table should include the exit interface as well as the next-hop IP address. This information is required to correctly encapsulate the frame. Layer 2 and 3 addresses are also required.TrueFalseQuestion 3 of 19 4. Put the routes in order of preference for IP address 10.1.1.1 0.0.0.0/0 10.1.1.1/32 10.0.0.0/8 10.1.1.0/24 10.1.0.0/16 Question 4 of 19 5. Put the routing table entry steps into the correct order: If the route entry is the same as an existing one and is received from the same protocol then: If the metric for both routes is the same, use both routes for load balancing Replace the existing route if the metric of the new route is lower Discard the new route if the metric is higher than the existing route Question 5 of 19 6. Once routes have been placed into the routing table, by default the most specific or longest match prefix will always be preferred over less specific routes.TrueFalseQuestion 6 of 19 7. Which route will be preferred for host 100.1.1.1? R 100.1.1.0/24 [120/1] via 10.1.1.2, 00:00:04, Ethernet0/0D 100.0.0.0/8 [90/281600] via 10.1.1.2, 00:02:02, Ethernet0/0O E2 100.1.0.0/16 [110/20] via 10.1.1.2, 00:00:14, Ethernet0/0The router will automatically load balance across all threeThe packet will be droppedQuestion 7 of 19 8. The advantage of using static routes is that an administrator doesn't need to update the route when there is a change to any routes in the network.TrueFalseQuestion 8 of 19 9. Your IT manager asks you to write a static route configuration for network 172.16.1.0/24 to go via next hop address 192.168.1.2 with an administrative distance of 110. What do you write? ip route 172.16.1.0 255.255.255.0 192.168.1.2 110ip route 192.168.1.2 172.16.1.0 255.255.255.0 110ip route 172.16.1.0 255.255.255.0 110 192.168.1.2ip route 172.16.1.0 255.255.255.0 192.168.1.2 eq 110Question 9 of 19 10. Your IT manager calls you to complain that there are a large number of ARP broadcasts for your static routes. What do you tell him the solution is?You can also specify an exit interface along with a next-hop address.You can add a low administrative distance to the end of the static route.You can swap static routes for dynamic routing.You can use internal NAT.Question 10 of 19 11. The _______ command is used on routers that have IP routing enabled and works best alongside routing protocols.ip default-networkip default-gatewayip route 0.0.0.0ip neighbor router 0.0.0.0Question 11 of 19 12.

Distance vector protocols are also referred to as ________ algorithms.Bellman-FordDijkstra'sCloakedHashedQuestion 14 of 19 15. Besides the fast convergence upside, distance vector protocols are also bandwidth efficient.TrueFalseQuestion 15 of 19 16. The ______ rule prevents any information or route learned on an interface from a router will not be advertised back on the same interface to the same router.split horizondual routingsplit routingcouting to infinityQuestion 16 of 19 17.

Link state protocols reflood their entire routing information every __ minutes in order to ensure that the network is properly converged (this is the case for OSPF at least).30605120Question 19 of 19 Loading...
