Data coms midterm reviewer 3

Question 1

Two routers, R1 and R2, have established an EIGRP neighbor relationship, but there is still a connectivity problem. Which issue could be causing this problem??

Answer 1

an access list that is blocking advertisements from other networks

Question 2

A router is running an EIGRP process and obtaining updates from other routers. What is an indication within the routing table that a route is a candidate for a default route?

Answer 2

*

Question 3

What is a disadvantage of using EIGRP automatic summarization?

Answer 3

It creates inconsistent routing when the network has discontiguous networks

Question 4

The OSPF hello timer has been set to 15 seconds on a router in a point-to-point network. By default, what is the dead interval on this router?

Answer 4

60 seconds

Question 4

When would the network administrator use the ip bandwidth-percent eigrp as-number percent command?

Answer 4

when there is a low bandwidth connection

Question 5

Which OPSF packet contains the different types of link-state advertisements?

Answer 5

LSU

Question 6

Which statement is correct about multiarea OSPF?

Answer 6

Arranging routers into areas partitions a large autonomous system in order to lighten the load on routers.

Question 7

A network administrator configures a loopback interface as the OSPF router ID with the IP address of 192.168.1.1/30. What could be the consequence of using this 30-bit mask for the loopback interface?

Answer 7

This loopback interface may be advertised as a reachable network.

Question 7

A network technician issues the following commands when configuring a router:

R1(config)# router ospf 11

R1(config-router)# network 10.10.10.0 0.0.0.255 area 0

What does the number 11 represent?

Answer 7

the OSPF process ID on R1

Question 8

A network administrator is analyzing the differences between an EIGRP hold timer and EIGRP hello interval. What statement is valid about EIGRP hello and hold timers?

Answer 8

EIGRP hello intervals should be less than or equal to EIGRP hold timers

Question 9

Which EIGRP parameter must match between all routers forming an EIGRP adjacency?

Answer 9

autonomous system number

Question 10

What is the default maximum amount of bandwidth that EIGRP uses for EIGRP control information considering an interface configured for 128 kbps?

Answer 10

64 kbps

Question 11

What is the purpose of the EIGRP Null0 summary route?

Answer 11

to prevent routing loops for destination networks which do not actually exist but are included in a summary route
