More questions
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.
Correct Answer: 5GHz
Explanation:
The IEEE 802.11a standard runs in the 5GHz RF range.
Correct Answer: 3
Explanation:
The IEEE 802.11b standard provides 3 non-overlapping channels.
