Question

A variable length net mask is a subnet mask with a variable prefix so that the same network may have different subnet masks with prefixes of different lengths. True False A routing loop occurs when two routers a packet back and forth WITHOUT it ever reaching its destination. True False Which two of the following will prevent a broadcast storm? a Forward/Filter decisions b Address learning C Bridges d Router layer 3 switch You need to troubleshoot an adjacency between two GRP configured routers? What should you look (Choose four) a Verify the AS numbers b Verify that you have the proper interfaces enabled for EIGRP.

Answer 1

Answer:

First question is true.

Second question is true.

Third question is incomplete there are four options:

a. Forward/Filter decisions

b. Address learning

c. Bridges

d. Router

e. layer 3 switch

The correct answer is d and e.

Fourth question is:

c. Make sure there are no mismatched K values.

d. Check your passive interface settings.

Explanation:

The first question is true because Variable-Length Subnet Masking (VLSM) use different masks.

The second question is true because the routing loop is when never reaching the destination and only two routers send a packet between them.

The third question is router and layer 3 switch because we must disconnect the routers and switches physically.

Fourth question

Make sure there are no mismatched K values, we must to looking for any mismatched value.

Check your passive interface settings, we must check the settings for this command.
