1. To test the IP stack on your local host, which IP address would you ping?
Loopback interfaces are created on a router, and the highest IP address on a loopback (logical) interface becomes the RID of the router but has nothing to do with areas and is optional, so (1) is wrong. The numbers you can create an area with are from 0 to 4,294,967,295 option (2) is wrong. The backbone area is called area 0, so option (3) is correct. All areas must connect to area 0, so option (5) is correct. If you have only one area, it must be called area 0. This leaves option (4), which must be correct; it doesn't make much sense, but it is the best answer.
This is a pretty simple question. A /28 is 255.255.255.240, which means that our block size is 16 in the fourth octet. 0, 16, 32, 48, 64, 80, etc. The host is in the 64 subnet.
7. What does a switch do when a frame is received on an interface and the destination hardware address is unknown or not in the filter table?
Options
A. Forwards the switch to the first available link
B. Drops the frame
C. Floods the network with the frame looking for the device
D. Sends back a message to the originating station asking for a name resolution
Correct Answer: Floods the network with the frame looking for the device
Explanation:
Switches flood all frames that have an unknown destination address. If a device answers the frame, the switch will update the MAC address table to reflect the location of the device.
8. Which of the following types of connections can use full duplex?
Hubs cannot run full-duplex Ethernet. Full duplex must be used on a point-to-point connection between two devices capable of running full duplex. Switches and hosts can run full duplex between each other, but a hub can never run full duplex.
9. What is the maximum distance with maximum data rate for 802.11a?
Correct Answer: ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.224
Explanation:
The command
ip nat pool <name> creates the pool that hosts can use to get onto the global Internet. What makes option B correct is that the range 171.16.10.65 through 171.16.10.94 includes 30 hosts, but the mask has to match 30 hosts as well, and that mask is 255.255.255.224. Option C is wrong because the pool name has a lower case "T" in the pool name. Pool name's are case sensitive.
