Question 1

What component of the backbone runs between a building's floors and can be used to connect an MDF and IDF or multiple IDFs?
A)horizontal cross connect
B)patch cable
C)vertical cross connect
D)diagonal cabling

Accepted Answer

The vertical cross connect runs between the floors of a building and is used to connect the MDF and IDF or multiple IDFs. The horizontal cross connect is used to connect end devices to the IDF and the patch cable is a type of cable used to connect equipment within the IDF. Diagonal cabling is not a commonly used term in networking.

Question 2

Select the component of enterprise level structured cabling that serves as the location where an incoming network interface enters a building and connects with the building's backbone cabling:
A)network interface device
B)main distribution frame
C)intermediate distribution frame
D)entrance facility

Accepted Answer

The entrance facility is the component of enterprise level structured cabling that serves as the location where an incoming network interface enters a building and connects with the building's backbone cabling. The network interface device is generally located in the customer premises and not at the entrance facility. The main distribution frame and intermediate distribution frame are used to connect horizontal cabling to the backbone cabling once it has entered the building through the entrance facility.

Question 6

When selecting a punch down block,what block type is more suitable for data connections?
A)10 block
B)22 block
C)66 block
D)110 block

Accepted Answer

The 110 block is considered more suitable for data connections as it allows for higher density and faster termination than other options, such as the 66 block. It is commonly used in Ethernet networks and can handle high-speed data transmissions.

Question 7

Select the two terms below that are used to describe a UPS that provides continuous voltage to a device by switching virtually instantaneously to the battery when it detects a loss of power:
A)offline UPS
B)standby UPS
C)standby power supply
D)failover power supply

Accepted Answer

A standby UPS switches to battery power when it detects a loss of power, providing continuous voltage to a device. A failover power supply is also used to provide continuous voltage to a device by switching to a backup power source when it detects a loss of power.

Question 8

During termination of twisted pair cabling,what should be done to ensure minimal cross talk is introduced?
A)No more than 1 inch of the cable should be exposed.
B)No less than 1 inch of the cable should be exposed.
C)Each pair should be stripped of insulation so that it doesn't get caught in the jack.
D)Each pair should be twisted around another pair to reduce cross talk.

Accepted Answer

Exposing no more than 1 inch of the cable helps to maintain the twists in the pairs as close to the termination point as possible, which reduces the potential for crosstalk with other pairs. If more than 1 inch is exposed, the twists can start to unravel, increasing the likelihood of interference.

Question 9

To ensure that any _____________ are detected,frames are made large enough to fill the entire cable during transmission.

Accepted Answer

The answer of To ensure that any _____________ are detected,frames...

Question 10

Select the two Transport Layer protocols that are used by SANs:
A)Fibre Channel
B)iSCSI
C)SAS
D)SATA

Accepted Answer

Fibre Channel and iSCSI are both transport layer protocols used in Storage Area Networks (SANs) for transmitting data. Fibre Channel is a high-speed network technology primarily used for storage networking, while iSCSI allows SCSI commands to be sent over IP networks, enabling the use of existing network infrastructure for storage. SAS (Serial Attached SCSI) and SATA (Serial ATA) are interfaces used for connecting storage devices like hard drives and SSDs, not transport layer protocols for SANs.

Question 11

_______ are highly scalable and have a very high fault tolerance,massive storage capabilities,and fast data access.

Question 12

In order to simplify console access to computers in a rack,what device is typically used to provide a central portal for all devices on the rack?
A)KVM switch
B)AVR switch
C)terminal server
D)multi-monitor breakout cable

Accepted Answer

A KVM (keyboard, video, mouse) switch is typically used to provide a central portal for all devices on a rack. It allows multiple devices to be controlled using a single set of input devices, including a keyboard, monitor, and mouse. This simplifies console access and makes it easier to manage multiple devices in a rack. Option B) AVR switch is used to control power to devices in a rack. Option C) Terminal Server is used to provide remote access to network devices using a terminal emulator. Option D) Multi-monitor breakout cable is used to connect multiple displays to a single computer or video source.

Question 16

If the use of a pre-existing Ethernet infrastructure is desired for a SAN,what Transport Layer protocol should be utilized?
A)Fibre Channel
B)iSCSI
C)SAS
D)PATA

Accepted Answer

iSCSI is the best choice for utilizing a pre-existing Ethernet infrastructure for a SAN. It allows for block-level storage access over Ethernet networks, avoiding the need for specialized Fibre Channel hardware. SAS and PATA are not used for SAN, and Fibre Channel requires specialized hardware.

Question 17

What cable type comes in two different modes,single mode and multimode?
A)UTP
B)STP
C)Fiber optic
D)Coaxial

Accepted Answer

Fiber optic cables come in both single mode and multimode options. Single mode fiber optic cables have a smaller core diameter and allow for higher speeds over longer distances, while multimode fiber optic cables have a larger core diameter and are typically used for shorter distances.
