- D. Issue the show cdp neighbors detail command on the router connected to the switch.
- Correct Answer
- Issue the show cdp neighbors detail command on the router connected to the switch.
ExplanationAlthough option A is certainly the "best" answer, unfortunately option D will work just fine and your boss would probably prefer you to use the show cdp neighbors detail command. - 1. What does the command o/r 0x2142 provide?
Options- A. It is used to restart the router.
- B. It is used to bypass the configuration in NVRAM.

- 2. The configuration register setting of 0x2102 provides what function to a router?
Options- A. Tells the router to boot into ROM monitor mode
- B. Provides password recovery
- C. Tells the router to look in NVRAM for the boot sequence
- D. Boots the IOS from a TFTP server Discuss
- 3. 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

More questions
Correct Answer: It is used to bypass the configuration in NVRAM.
Explanation:
The default configuration setting is
0x2102, which tells the router to load the IOS from flash and the configuration from NVRAM.
0x2142 tells the router to bypass the configuration in NVRAM so that you can perform password recovery.
Correct Answer: Tells the router to look in NVRAM for the boot sequence
Explanation:
The default configuration setting of 0x2102 tells the router to look in NVRAM for the boot sequence.
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.
