29. You router has the following routes: 10.1.4.0/24, 10.1.5.0/24, 10.1.6.0/24, 10.1.7.0/24. You want to summarize these via BGP so that only the summary route is advertised. What command will accomplish this?
30. Which of the following correctly describes an OSPF Area Border Router?
a. It is used to connect various OSPF Areas
b. It is used only at the outside edge of an OSPF network for protocol translation
c. It is used only internally for OSPF to EIGRP redistribution
d. It is used for routing protocol redistribution
31. What will the command ‘debug ip ospf adj’ help to accomplish?
a. LSA type 1
b. Elections
c. LSA type 3 and 4
d. OSPF neighbor relationships
32. What OSPF command on the Area Border Router will summarize all routes going into area 9 with a 0.0.0.0 default route?
33. What command will make OSPF area 9 a Stub Area?
34. When BGP routers with the same AS number exchange information, this is known as ____?
a. BGP
b. EBGP
c. IGRP
d. IBGP
35. Which of the following are characteristics of the BGP routing protocol?
a. Link-state protocol
b. Interior gateway protocol
c. Exterior gateway protocol
d. Distance-Vector protocol
36. Which of the following is untrue of routers running internal BGP?
a. Routers are running IBGP when two BGP speaking routers are in different AS’s
b. They must form a TCP port 179 connection with each other
c. They do not have to be directly connected
d. Routers are running IBGP when two BGP speaking routers are in the same AS
37. Which of the following are true of a network design with a high number of OSPF routers in a single area?
a. Increased problems with routing table ‘black holes’
b. Increased SPF algorithm re-calculation times
c. Decreased OSPF update traffic overhead
d. Increased OSPF update traffic overhead
38. What is included in an OSPF DBD/DDP?
a. SPF entries from the OSPF routing table
b. STP entries from the OSPF spanning tree
c. LSA entries from the OSPF master router’s link-state database
d. Database Description Packets
39. What command would be most useful for determining if there is an access-list applied to an interface?
40. Which of these values is required by EIGRP as a Seed Metric when performing Route Redistribution?
a. Bandwidth, Delay, Reliability, Load, MTU
b. Cost, Delay, Reliability
c. Route-Tag
d. Cost
41. By default OSPF will not allow the network address ‘0.0.0.0’ to be generated into the routing table in normal Areas. The ‘ip classless’ command tells Distance Vector routing protocols like RIP and IGRP to ignore the Class A/B/C rules and allow the default route ‘0.0.0.0’ network entry to be propagated. What corresponding OSPF command on the ASBR for a normal area will accomplish the same goal?
42. Which of the following are true regarding an OSPF internal router?
a. Internal routers are in more than one area
b. At least one interface is in Area 0
c. All interfaces are in the same Area
d. Internal routers redistribute routing information with routers in other areas
43. What is the inverted wildcard mask of /26?
a. 63.255.255.255
b. 0.0.0.63
c. 192.255.255.255
d. 0.0.0.192
44. You attempt to start an OSPF process on your router and receive: ‘Unable to allocate router ID.’ What could be the problem?
a. The OSPF area is Stubby
b. No IP address assigned to any interface
c. Router ID is used by another router
d. All interfaces are shut down
45. Which route types are passed by an OSPF ABR into a Totally Stubby Area?
a. Generate Type 3-4
b. Generate Type 5
c. Generate 0.0.0.0
d. Generate Type 1-2
46. Which of the following are true of Route Reflectors?
a. The reduce the size of the BGP table
b. They enable the use of Route Summarization

b. Use the network command with the ‘mask’ option
c. Redistribute BGP into the IGP
d. Use the network command without the ‘mask’ option
48. Which of the following are reasons a network administrator would choose to run multiple routing protocols at the same time on the same network?
a. Reduce routing protocol overhead on the network
b. Optimize the route redistribution between areas
c. Convert from an older routing protocol to a more modern one
d. Acquisition of a company running a different routing protocol than your own
49. When would you not use BGP?
a. Routing policy and route selection are not important for your AS
b. A single connection to the Internet
c. When you need to perform load-sharing to multiple ISP’s simultaneously
d. Low bandwidth between your AS and the other AS
50. What are some advantages of tunneling IPX through IP?
a. Saves IPX network address space
