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.
Correct Answer: Breaks up broadcast domains in a layer 2 switch internetwork.
Explanation:
VLANs break up broadcast domains at layer 2.
Correct Answer: In the routing table and the topology table
Explanation:
Successor routes are going to be in the routing table since they are the best path to a remote network. However, the topology table has a link to each and every network, so the best answer is topology table and routing table. Any secondary route to a remote network is considered a feasible successor, and those routes are only found in the topology table and used as backup routes in case of primary route failure.
Correct Answer: 1, 2 and 3
Explanation:
OSPF is created in a hierarchical design, not a flat design like RIP. This decreases routing overhead, speeds up convergence, and confines network instability to a single area of the network.
Correct Answer: 192.168.168.129-190
Explanation:
256 - 192 = 64. 64 + 64 = 128. 128 + 64 = 192. The subnet is 128, the broadcast address is 191, and the valid host range is the numbers in between, or 129-190.
