- Question
You want to create a standard access list that denies the subnet of the following host: 172.16.198.94/19. Which of the following would you start your list with?
Options- A. access-list 10 deny 172.16.192.0 0.0.31.255
- B. access-list 10 deny 172.16.0.0 0.0.255.255
- C. access-list 10 deny 172.16.172.0 0.0.31.255
- D. access-list 10 deny 172.16.188.0 0.0.15.255
- Correct Answer
- access-list 10 deny 172.16.192.0 0.0.31.255
ExplanationFirst, you must know that a /19 is 255.255.224.0, which is a block size of 32 in the third octet. Counting by 32, this makes our subnet 192 in the third octet, and the wildcard for the third octet would be 31 since the wildcard is always one less than the block size. - 1.

Correct Answer: 127.0.0.1
Explanation:
To test the local stack on your host, ping the loopback interface of 127.0.0.1.
Correct Answer: show ip interface
Explanation:
The
show ip interface command will show you if any outbound or inbound interfaces have an access list set.
Correct Answer: ip access-group 101 in
Explanation:
To apply an access list, the proper command is
ip access-group 101 in.
Correct Answer: 3, 4 and 5
Explanation:
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.
Correct Answer: debug ip rip
Explanation:
The
debug ip rip command is used to show the Internet Protocol (IP) Routing Information Protocol (RIP) updates being sent and received on the router.
Correct Answer: 200.10.5.64
Explanation:
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.
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.
Correct Answer: 2, 3 and 5
Explanation:
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.
Correct Answer: About 65-75 feet
Explanation:
The IEEE 802.11a standard provides a maximum data rate of up to 54Mbps, but you need to be close to the access point, somewhere around 65 to 75 feet.
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.
