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.
Correct Answer: 2, 3 and 6
Explanation:
VLANs break up broadcast domains in a switched layer 2 network, which means smaller broadcast domains. They allow configuration by logical function instead of physical location and can create some security if configured correctly.
Correct Answer: 5
Explanation:
A 240 mask is 4 subnet bits and provides 16 subnets, each with 14 hosts. We need more subnets, so let's add subnet bits. One more subnet bit would be a 248 mask. This provides 5 subnet bits (32 subnets) with 3 host bits (6 hosts per subnet). This is the best answer.
Correct Answer: 3, 4 and 5
Explanation:
Telnet, File Transfer Protocol (FTP), and Trivial FTP (TFTP) are all Application layer protocols. IP is a Network layer protocol. Transmission Control Protocol (TCP) is a Transport layer protocol.
Correct Answer: The switch port the host is connected to is not configured to the correct VLAN membership.
Explanation:
This question is a little vague, but the best answer is that the VLAN membership for the port is not configured.
