1. Correct Answer: B


802.11b is the most widely deployed wireless standard and operates in the 2.4GHz band with
a data rate of up to 11Mbps.

2. Correct Answer: A

802.11a operates in the 5GHz band with a data rate of up to 54Mbps and is immune to
interference from other devices operating in the 2.4GHz spectrum.

3. Correct Answer: C


Here in the question the A is administrative distance 110 for OSPF, B is 1 for Static
Route, D is 90 for Internal EIGRP, E is 100 for IGRP so the last C is 120 for RIP. Here You
must be carefull for Internal and External EIGRP's administrative distance and Internal and
xternal BGP. 

4. Correct Answer: A


192.168.10.0 is a class C address.  The subnet mask 255.255.255.192 implies 2 bits are
borrowed. 22 = 4 subnets

5.Correct Answer: D

no cdp run - When disabling a command you use "no" form of the command
