- Question
You copy a configuration from a network host to a router's RAM. The configuration looks correct, yet it is not working at all. What could the problem be?
Options- A. You copied the wrong configuration into RAM.
- B. You copied the configuration into flash memory instead.
- C. The copy did not override the shutdown command in running-config.
- D. The IOS became corrupted after the copy command was initiated.
- Correct Answer
- The copy did not override the shutdown command in running-config.
ExplanationSince the configuration looks correct, you probably didn't screw up the copy job. However, when you perform a copy from a network host to a router, the interfaces are automatically shut down and need to be manually enabled with the no shutdown command. - 1. What is the purpose of flow control?
Options- A. To ensure that data is retransmitted if an acknowledgment is not received.
- B. To reassemble segments in the correct order at the destination device.
- C. To provide a means for the receiver to govern the amount of data sent by the sender.
- D. To regulate the size of each segment. Discuss

- If your design is hierarchical, then you don't need multiple areas.
- All areas must connect to area 0.

Correct Answer: To provide a means for the receiver to govern the amount of data sent by the sender.
Explanation:
Flow control allows the receiving device to control the transmitter so the receiving device's buffer does not overflow.
Correct Answer: 1 ,2 and 4
Explanation:
The
tracert command is a Windows command and will not work on a router! A router uses the
traceroute command.
Correct Answer: Switch(config-if)# switchport trunk encapsulation dot1q
Explanation:
If you are on a 2950 switch, then the interface command is just
switchport mode trunk, since the 2950 can only run the IEEE 802.1Q version. However, a 3550 can run both ISL and 802.1Q, so you must use the encapsulation command. The argument to choose 802.1Q for a trunking protocol is
dot1q.
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.
