Question 1

Color codes for cross-connection fields have been used for many years. Which color is used to identify network connections?

Accepted Answer

Green is used to identify network connections.

Question 2

All of the following are used to control static discharge EXCEPT:

Accepted Answer

All of the other options listed (ion generator, discharge plates and bracelets, and maintenance of humidity) are methods commonly used to control static discharge. Installing isolated grounds does not necessarily control static discharge and may serve other purposes such as reducing electrical interference.

Question 3

Which of the following electrical devices is used to convert AC to DC?

Accepted Answer

A rectifier is used to convert AC to DC by allowing current flow in only one direction. Inverters, transformers, and line filters do not convert AC to DC.

Question 4

You have been asked to provide a UPS that is always serving the load from its batteries and the electrical supply is used only to recharge the batteries. Which one of the following types of UPS will meet this requirement?

Accepted Answer

An online double conversion UPS is the best choice for this requirement as it provides continuous power supply to the load from its batteries and the electrical supply is only used to recharge the batteries. In an online double conversion UPS, the incoming AC power is first rectified to DC, then inverted back to AC to supply power to the load, and then rectified and inverted again to charge the batteries. This process ensures that the load is always powered by the batteries, providing stable and uninterrupted power supply.

Question 5

A large telecommunications facility, by most codes, must be designed with an EPO switch located at:

Accepted Answer

The EPO (Emergency Power Off) switch is typically required to be located at the facility entrance or exit to allow for quick and easy access in case of an emergency, ensuring the safety of personnel and equipment.

Question 6

Assume the following: - An equipment room (ER) consists of 16 racks arranged in 4 equal rows - The first 4 racks are numbered R1-1 though R1-4 - The second 4 racks are numbered R2-1 through R2-4 - A new equipment shelf with 12 slots is to be installed in the bottom of the third rack in the second row - Each slot has 2 ports What would be the identifier of the two ports on the eighth slot of the new equipment shelf?

Accepted Answer

The identifier for the new equipment shelf would be R2-3-1 (third rack in the second row). The eighth slot on this shelf would be numbered 8. Therefore, the identifier for the two ports on the eighth slot would be R2-3-1-8-1 and R2-3-1-8-2.

Question 7

Which one of the following is part of the security metric to consider in selecting the appropriate labels for an administrative system?

Accepted Answer

Tamper resistance is a crucial security metric to consider when selecting labels for an administrative system. It ensures that the label cannot be removed or tampered with easily, preventing unauthorized access or alteration to the system. The other options listed are not relevant security metrics for labels used in an administrative system.

Question 8

For the telecommunications industry, the nominal operating voltage is ________ volts DC.

Accepted Answer

The telecommunications industry typically uses a nominal operating voltage of -48 volts DC to power equipment, which helps prevent corrosion and provides a stable power supply.

Question 9

DC loads are generally expressed in:

Accepted Answer

The answer of DC loads are generally expressed in:
...

Question 10

Which class of the system applies when the premise only has a single equipment room (ER), and it is the only telecommunications space administered?

Accepted Answer

Class 1 applies when the premise has a single ER as the only telecommunications space administered.

Question 11

You have been asked to provide a N+1 level of power redundancy in the new equipment room (ER) being designed with a Tier-II power supply. What should you do?

Accepted Answer

The answer of You have been asked to provide a...

Question 12

Class ________ administration provides for the telecommunications infrastructure administration needs of a single building, or of a tenant served by a single or multiple. It also includes administration for backbone cabling, systems, and.

Accepted Answer

The answer of Class ________ administration provides for the telecommunications...

Question 13

In an industry where a high level of humidity is measured, which type of label should be used?

Accepted Answer

A label that is moisture-induced decay and degradation resistant would be best suited for an industry where a high level of humidity is measured, as this type of label is designed to withstand exposure to moisture and prevent decay or degradation over time.

Question 14

You are designing a large equipment room (ER) that will house many servers, switches, backup storage drives, and other communications equipment including peripheral devices. To prevent problems from harmonic currents that can be created by switching power supplies, you should arrange for:

Accepted Answer

Harmonic currents can cause overheating in neutral conductors. Oversizing neutral and grounding conductors helps manage these currents effectively.

Question 15

When labeling pathways, which one of the following guidelines should be met?

Accepted Answer

Labeling should be affixed at the ends of each pathway to clearly indicate the start and end points of the pathway. This helps in identifying the pathway in case of any future changes or issues.

Question 16

Which class of the system was created to secure a single equipment room (ER)?

Accepted Answer

Class 1 is the class of the system that was created to secure a single equipment room (ER).

Question 17

An isolated ground is used to:

Accepted Answer

An isolated ground is designed to reduce electromagnetic interference (EMI) and radio frequency interference (RFI) in electrical circuits. It establishes a separate ground path for sensitive equipment, which can reduce the amount of interference that enters the system. It is not designed to reduce transients, prevent interruptions, or reduce swells and sags.

Question 18

Multiples of the basic frequency of an electrical waveform are called:

Accepted Answer

Multiples of the basic frequency are called harmonics. Transients are brief bursts of energy, noise inductions are disturbances caused by external factors, and random frequency variations refer to non-coherent frequency fluctuations.

Question 19

Color codes for cross-connections fields have been used for many years. Which color is used to identify campus backbone?

Accepted Answer

The answer of Color codes for cross-connections fields have been...

Question 20

If a telecommunications grounding busbar is installed in the telecommunications room (TR) with the identifier of 310, located on the third floor, then the telecommunications grounding busbar should be labeled as:

Accepted Answer

It is important to label the telecommunications grounding busbar with a unique identifier to accurately identify it for maintenance, troubleshooting, and safety purposes. The identifier should be clear and straightforward, incorporating the room number and the purpose of the busbar. In this case, the identifier of 310 should be incorporated into the label, and the purpose of the busbar as the telecommunications grounding busbar should also be included. Therefore, the best choice would be option A, which labels the busbar as TGB-310.
