Correct Answer: About 350 feet
Explanation:
The IEEE 802.11b standard provides the lowest data rate at 1Mbps, but it also has the longest distance, which is about 350 feet.
Correct Answer: show ip eigrp neighbors
Explanation:
The
show ip eigrp neighbors command allows you to check the IP addresses as well as the retransmit interval and queue counts for the neighbors that have established an adjacency.
Correct Answer: So different networks could communicate.
Explanation:
The primary reason the OSI model was created was so that different networks could inter-operate.
Correct Answer: show version
Explanation:
The
show version command provides you with the current configuration register setting.
Correct Answer: copy running-config startup-config
Explanation:
The command to back up the configuration on a router is
copy running-config startup-config.
Correct Answer: 128 bits
Explanation:
An IPv6 address is 128 bits long.
Correct Answer: 110
Explanation:
The administrative distance (AD) is a very important parameter in a routing protocol. The lower the AD, the more trusted the route. If you have IGRP and OSPF running, by default IGRP routes would be placed in the routing table because IGRP has a lower AD of 100. OSPF has an AD of 110. RIPv1 and RIPv2 both have an AD of 120, and EIGRP is the lowest, at 90.
Correct Answer: RouterA(config-if)#clock rate 64000
Explanation:
The
clock rate command is two words, and the speed of the line is in bps.
Correct Answer: 1 and 4
Explanation:
Successor routes are the routes picked from the topology table as the best route to a remote network, so these are the routes that IP uses in the routing table to forward traffic to a remote destination. The topology table contains any route that is not as good as the successor route and is considered a feasible successor, or backup route. Remember that all routes are in the topology table, even successor routes.
Correct Answer: 1, 2 and 4
Explanation:
The most popular use of NAT is if you want to connect to the Internet and you don't want hosts to have global (real) IP addresses, but option B and D are correct as well.
