| Which action will NOT reduce the bandwidth used by routing updates?
A. Creating a summary route
B. Configuring a passive interface
C. Applying an outbound filter
D. Applying an inbound filter
The answer is B.
--------------------------------------------
You have configured route redistribution between separate routing domains and have included route filters to prevent route feedback. Which command should you use on a non-boundary router to verify that redistribution is working correctly?
A. show ip route
B. show ip access-lists
C. debug distribute-lists
D. ping
The answer is A.
---------------------------------------------
Routers running classless routing protocols use ______ ______ prefix match when selecting a route from the routing table:
A. the shortest
B. a summarized
C. an even number
D. the longest
The answer is A.
---------------------------------------------
When trying to determine a match for a destination network, a classless routing protocol looks for the ____________ match in the routing table?
A. first
B. longest
C. leading octet
D. closest
The answer is A.
---------------------------------------------
When configuring EIGRP for WAN interfaces, the BANDWIDTH statement is _____.
A. Required for Frame Relay only
B. Required for subinterfaces only
C. Not required
D. Only used for
The answer is B.
---------------------------------------------
When using Enhanced IGRP in large scalable networks, why is additional EIGRP configuration required?
A. to be hierarchical
B. to adjust only WAN bandwidth because EIGRP is preconfigured (Plug and Play)
C. to be monitored by the administrator
D. to create manually entered summary routes
The answer is D

| As a rule, you'll be better off starting a few threads, each with only a couple of questions, instead of one thread with a lot of questions. Many people don't even bother reading posts that don't fit in one screen.
This said, here's my shot at some of your questions:
Which action will NOT reduce the bandwidth used by routing updates?
A. Creating a summary route
B. Configuring a passive interface
C. Applying an outbound filter
D. Applying an inbound filter
The answer is B.
(my answer was wrong; listen to Terje)
Routers running classless routing protocols use ______ ______ prefix match when selecting a route from the routing table:
A. the shortest
B. a summarized
C. an even number
D. the longest
The answer is A.
D. When you have overlapping routes in the routing table, the more specific (i.e., longest prefix) is preferred. (I hope I understand correctly what the question asks.)
When trying to determine a match for a destination network, a classless routing protocol looks for the ____________ match in the routing table?
A. first
B. longest
C. leading octet
D. closest
The answer is A.
B. As before.

The answer is B.
Creating a summary route will reduce bandwith usage because one routing update is sent in place of many.
Configuring a passive interface will reduce bandwith usage because this interface will not send routing updates. I think the meaning of passive interface varies a bit between routing protocols.
Applying an outbound filter will reduce bandwith usage because some updates that would be sent without the filter will not be sent with it.
Applying an inbound filter will not help. The filter will discard some updates, but only after they have allready consumed bandwith.

The answer is A.
Or D? The most specific route will be chosen. That's the one with the longest prefix match. Reread this part of your book before you go to the next question.

I do not think it is ever required. It is usefull when there are multiple routes to a destination. EIGRP and some other routing protocols use it for selecting the best route.
