Module 13 Exam

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.

2. Before forwarding a frame the TTL field must then be incremented and a new header checksum calculated.

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.

4. Put the routes in order of preference for IP address 10.1.1.1

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:

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.

7. Which route will be preferred for host 100.1.1.1?

 

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.

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?

 

 

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?

11. The _______ command is used on routers that have IP routing enabled and works best alongside routing protocols.

12. Put the administrative distances with the correct protocols.

13. Match the correct class to the routing protocol.

14. Distance vector protocols are also referred to as ________ algorithms.

15. Besides the fast convergence upside, distance vector protocols are also bandwidth efficient.

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.

17. Features of Distance Vector protocols include? (choose all that apply)

18. Which command will create a passive interface for EIGRP?

19. 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).
