Question 1

The RJ-45 is now known as the 8P8C style connector, per the Telecommunications Industry Association (TIA) standard. What does the P and C stand for?

Accepted Answer

The P stands for position and the C stands for contact.

Question 2

When installing outlet boxes in ten private offices in an area which may prove to be difficult to install future additional telecommunications outlets, the MINIMUM quantity of outlet boxes that should be installed is:

Accepted Answer

Installing at least two outlet boxes per office will allow for future flexibility and reduce the need for costly and disruptive retrofits if additional telecommunications outlets are needed. Therefore, a minimum of 20 outlet boxes should be installed for the ten private offices.

Question 3

An open office design is made up of three furniture clusters and contains a total of nine. How many multiuser telecommunications outlet assemblies (MUTOA) should be in the design?

Accepted Answer

Each furniture cluster should have at least one MUTOA, so with three clusters, three MUTOAs are needed.

Question 4

Which of the following is NOT an example of a perimeter pathway?

Accepted Answer

Furniture pathways are not perimeter pathways as they are not located along the perimeter of a room or space. Perimeter pathways are typically installed along the walls or baseboards and are used to route cabling and wiring around a room. Examples of perimeter pathways include surface raceways, multi-channel raceways, under carpet cabling, and raceways integrated within walls.

Question 5

The MINIMUM separation distance between grounded metal telecommunications pathway and unshielded power lines is:

Accepted Answer

According to the National Electrical Safety Code (NESC), the minimum separation distance between grounded metal telecommunications pathway and unshielded power lines is 300 mm (12 in) to prevent electrical interference and ensure safety.

Question 6

What type of fiber optic cable is manufactured to protect individual glass strands and is primarily designed for use inside buildings?

Accepted Answer

Tight buffered fiber optic cable is primarily designed for indoor use, as it has a protective coating surrounding each glass strand. This makes it more durable and easier to handle during installation compared to loose tube or ribbon fiber optic cable. Air blown fiber optic cable, on the other hand, is used for long distance outdoor installations as it allows for easy upgrades or modifications in the future without the need for additional cable installation.

Question 7

Which of the following is NOT true about consolidation points?

Accepted Answer

The answer of Which of the following is NOT true...

Question 8

Which of the following is NOT a type of connector for optical fiber?

Accepted Answer

S/FTP is not a type of connector for optical fiber. It refers to a type of shielded twisted pair cabling used in Ethernet networks. The other choices (LC, ST, SFF, and SC) are all valid types of connectors for optical fiber.

Question 9

The ability of a conductors insulation to transmit an electric field is called:

Accepted Answer

The ability of a conductor's insulation to transmit an electric field is called permittivity. Conductivity refers to the ability of a material to conduct electricity, and transmitability is not a term commonly used in electrical engineering. Capacitance is the ability of a material to store an electric charge, and reactance is the resistance of a circuit to changes in voltage or current.

Question 10

This type of cable is an unbalanced system:

Accepted Answer

Coaxial cable uses a single conductor surrounded by a shield, making it an unbalanced system. UTP, STP, and ScTP are all examples of balanced systems.

Question 11

A telecommunications outlet/connector may be provided using all listed below EXCEPT:

Accepted Answer

The 4p4c connector is typically used for telephone handsets, not for telecommunications outlets/connectors in structured cabling systems.

Question 12

If looking to specify an optical fiber backbone within a building going 275 m (902 ft) between the equipment room (ER) and the telecommunications room (TR), what type of fiber should be specified to support a 10 GB ethernet application?

Accepted Answer

For a 10 GB Ethernet application, the minimum recommended fiber type is 50 micron laser optimized multimode (OM3 or OM4). OM1 and 62.5 micron multimode fibers are not suitable for 10 GB Ethernet applications. Therefore, the best choice for this scenario is 50 micron laser optimized multimode.

Question 13

Which of the following is true about screened twisted pair cable assemblies?

Accepted Answer

The drain wire and screen foil in a screened twisted pair cable must be bonded at every connection to ensure proper grounding and shielding effectiveness.

Question 14

On a project with three small conference rooms, a break room, and twelve private offices, what is the MINIMUM number of telecommunications outlet boxes required?

Accepted Answer

The answer of On a project with three small conference...

Question 15

In a run requiring 15 m (50 ft) of cable between the floor distributor and the consolidation point, the MAXIMUM length of cable allowed between the CP and the telecommunications outlet is:

Accepted Answer

The answer of In a run requiring 15 m (50...

Question 16

Important considerations when designing telecommunications distribution within modular furniture include all of the following EXCEPT:

Accepted Answer

The maximum initial fill ratio of 40 percent when derated because of corners is not a standard consideration for telecommunications distribution in modular furniture.

Question 17

You are extending 1000 MHz video service from your existing headend to a new equipment room (ER). Your existing incoming video signal is plus (+) 15 dBmV. You have three two-way splitters with a total of minus (-) 15 dB. You are adding 122 m (400 ft) of series 11 (RG 11) cable with a minus (-) 18 dB with eight single end F-connectors with a total of minus (-) 1.2 dB. From the selections below, what is the MINIMUM gain amplifier required in the headend room?

Accepted Answer

The answer of You are extending 1000 MHz video service...

Question 18

Assuming the total fill capacity of a pathway is 100 cables (all of the same cable type and size), the MAXIMUM number of cables to be installed during the initial installation, without exceeding the fill ratio is:

Accepted Answer

The answer of Assuming the total fill capacity of a...

Question 19

When specifying telecommunications outlet boxes, all of the following should be considered EXCEPT:

Accepted Answer

The size of the outlet box is not a standard requirement and can vary based on specific needs and installations.

Question 20

A furniture cluster with 26 requires a MINIMUM of how many multiuser telecommunications outlet assembly (MUTOA)?

Accepted Answer

According to TIA/EIA Standards, a furniture cluster with 26 requires a minimum of three multiuser telecommunications outlet assembly (MUTOA).
