- Question
IGRP uses which of the following as default parameters for finding the best path to a remote network?
- Hop count
- MTU
- Cumulative interface delay
- STP
- Path bandwidth value
Options- A. 1 and 3
- B. 3 and 5
- C. 2, 3 and 5
- D. All of the above
- Correct Answer
- 3 and 5
ExplanationIGRP uses bandwidth and delay of the line, by default, to determine the best path to a remote network. Delay of the line can sometimes be called the cumulative interface delay. - 1. What is the frequency range of the IEEE 802.11b standard?
Options- A. 2.4Gbps
- B. 5Gbps
- C. 2.4GHz
- D. 5GHz Discuss
- 2. You are troubleshooting a connectivity problem in your corporate network and want to isolate the problem. You suspect that a router on the route to an unreachable network is at fault. What IOS user exec command should you issue?
Options- A. Router> ping
- B. Router> trace
- C. Router> show ip route
- D. Router> show interface Discuss
- 3. Your switch has a port status LED that is alternating between green and amber. What could this indicate?
Options- A. The port is experiencing errors.
- B. The port is shut down.
- C. The port is in STP blocking mode.
- D. Nothing; this is normal. Discuss
- 4. A network administrator needs to configure a router with a distance-vector protocol that allows classless routing. Which of the following satisfies those requirements?
Options- A. IGRP
- B. OSPF
- C. RIPv1
- D. EIGRP
- E. IS-IS Discuss
- 5. What command is used to stop RIP routing updates from exiting out an interface but still allow the interface to receive RIP route updates?
Options- A. Router(config-if)# no routing
- B. Router(config-if)# passive-interface
- C. Router(config-router)# passive-interface s0
- D. Router(config-router)# no routing updates Discuss
- 6. Which of the following services use TCP?
- DHCP
- SMTP
- HTTP
- TFTP
- FTP
Options- A. 1 and 2
- B. 2, 3 and 5
- C. 1, 2 and 4
- D. 1, 3 and 4 Discuss

- B. 3 only
- C. 2 and 4 only
- D. All of the above Discuss
- 8. Acknowledgments, sequencing, and flow control are characteristics of which OSI layer?
Options- A. Layer 2
- B. Layer 3
- C. Layer 4

Options- A. 3
- B. 12
- C. 23
- D. 40 Discuss
- 10. You need to gather the IP address of a remote switch that is located in Hawaii. What can you do to find the address?
Options- A. Issue the show ip arp command on the router connected to the switch.
- B. Issue the show ip route command on the router connected to the switch.
- C. Issue the show cdp neighbor command on the router connected to the switch.
- D. Issue the show cdp neighbors detail command on the router connected to the switch. Discuss

Correct Answer: 2.4GHz
Explanation:
The IEEE 802.11b and IEEE 802.11g standards both run in the 2.4GHz RF range.
Correct Answer: Router> trace
Explanation:
The command
traceroute (trace for short), which can be issued from user mode or privileged mode, is used to find the path a packet takes through an internetwork and will also show you where the packet stops because of an error on a router.
Correct Answer: The port is experiencing errors.
Explanation:
When you connect to a switch port, at first the link lights are orange/amber, and then they turn green, indicating normal operation. If the link light is blinking, you have a problem.
Correct Answer: EIGRP
Explanation:
In this question, we're calling EIGRP just plain old distance vector. EIGRP is an "advanced" distance-vector routing protocol, sometimes called a hybrid routing protocol because it uses the characteristics of both distance-vector and link-state routing protocols.
Correct Answer: Router(config-router)# passive-interface s0
Explanation:
The
(config-router)#passive-interface command stops updates from being sent out an interface, but route updates are still received.
Correct Answer: 2, 3 and 5
Explanation:
SMTP, HTTP and FTP use TCP.
Correct Answer: 2 and 4 only
Explanation:
The best answers, the ones you need to remember, are that either an access control list is filtering the Telnet session or the VTY password is not set on the remote device.
Correct Answer: Layer 4
Explanation:
A reliable Transport layer connection uses acknowledgments to make sure all data is transmitted and received reliably. A reliable connection is defined by a virtual circuit that uses acknowledgments, sequencing, and flow control, which are characteristics of the Transport layer (layer 4).
Correct Answer: 3
Explanation:
The IEEE 802.11g standard provides 3 non-overlapping channels.
Correct Answer: Issue the show cdp neighbors detail command on the router connected to the switch.
Explanation:
Although 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.
