Which of the following cable types is required to run through an air duct?

 

A.

UTP

B.

Fiber

C.

PVC

D.

Plenum

 

Correct Answer: D

Explanation:

Plenum rated cable has a special insulation that has low smoke and low flame characteris
tics. Plenum cable is mandated to be installed in any “air handling” space. For example, most large office buildings use the ceiling to return air to the AC unit. This qualifies this ceiling as a plenum ceiling, and all the cables that go through that ceiling must be plenum rated.

 

 

QUESTION 144

Which of the following would be used to connect a singlemode fiber cable to a CAT6 connection?

 

A.

Media converter

B.

T1-crossover

C.

Multimode cable

D.

Coaxial

 

Correct Answer: A

Explanation:

< span lang="EN-US" style="font-family: ; mso-font-kerning: 0pt; mso-no-proof: yes">Media converters support many different data communication protocols including Ethernet, Fast Ethernet, Gigabit Ethernet, T1/E1/J1, DS3/E3, as well as multiple cabling types such as coax, twisted pair, multi-mode and single-mode fiber optics.

A.

SSID

B.

Scope

C.

Reservation

D.

Lease

 

Correct Answer: C

QUESTION 148

A technician needs multiple networks, high speeds, and redundancy on a system. Which of the following configurations should be considered for these requirements? (Select TWO).

 

A.

Routing table

B.

Next hop

C.

Port mirroring

D.

Port monitoring

E.

VLANs

 

Correct Answer: CE

Explanation:

Port mirroring is used on a network switch to send a copy of network packets seen on one switch port (or an entire VLAN) to a network monitoring connection on another switch port. This is commonly used for network appliances that require monitoring of network traffic, such as an intrusion detection system, passive probe or real user monitoring (RUM) technology that is used to support application performance management (APM).

 

In computer networking, a single layer-2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them via one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN or VLAN.

 

 

QUESTION 149

After a network technician has added a new workstation and cabling to the network, users report the network is very slow. The activity lights on all switches are blinking rapidly, showing large amounts of traffic. Which of the following is the BEST explanation for the traffic?

 

A.

The new user is downloading large files.

B.

The router failed, flooding the network with bea
cons.

C.

The new user’s IP address is a duplicate.

D.

A switching loop was created.

 

Correct Answer: D

Explanation:

A Switching loop or Bridge loop occurs in computer networks when there is more than one Layer 2 (OSI model) path between two endpoints (e.g. multiple connections between two network switches or two ports on the same switch connected to each other). The loop creates broadcast radiation as broadcasts and multicasts are forwarded by switches out every port, the switch or switches will repeatedly rebroadcast the broadcast messages flooding the network.
