Question 1

A properly designed distributed paging system will provide a sound pressure level (SPL) for audio paging that is between ________ above ambient noise level.

Accepted Answer

The answer of A properly designed distributed paging system will...

Question 2

Exhibit:  The following diagram indicates what type of CATV distribution system?

Accepted Answer

The diagram shows a CATV distribution system where there is a main trunk line splitting into multiple smaller branches (taps) to distribute the signal to individual households. This is known as the trunk and tap approach, making option A the correct answer. The other options (video over balanced twisted-pair, video over optical fiber, and home run) do not accurately match the distribution method shown in the diagram.

Question 3

What is the appropriate impedance of coaxial cable for use with broadband distribution?

Accepted Answer

The appropriate impedance of coaxial cable for use with broadband distribution is 75 ohms. This is because the standard impedance used for transmitting and receiving signals in cable television and other broadband applications is 75 ohms. Using a cable with a different impedance can cause signal loss and interference, which can affect the quality of the transmission. Therefore, choice B (75) is the best choice.

Question 4

Exhibit: The figure below represents what type of chart?

Accepted Answer

The answer of Exhibit: The figure below represents what type...

Question 5

Which area of project management covers the blending of various subteams into a project organization with a cohesive plan?

Accepted Answer

Integration management covers the integration of all project components, including subteams, into a cohesive project plan. Human resources management deals with staffing and team development. Risk management deals with identifying and mitigating potential project risks. Communications management deals with managing project communications.

Question 6

A building has six floors plus a basement. Each floor is 929 sq m (10,000 sq ft) and has approximately 50 CATV outlets respectively. There is a single hardline trunk cable installed from the basement headend passing through the telecommunications room (TR) on each floor. In order to maintain the LEAST signal loss passing through each telecommunications room (TR) to the next telecommunications room (TR), what device should you specify for use within each telecommunications room (TR)?

Accepted Answer

A directional coupler is the best choice to maintain the least signal loss passing through each TR to the next TR. Directional couplers allow one signal to pass through in one direction while coupling a small portion of that signal in a different direction. This allows for minimal signal loss while distributing the signal to multiple outlets. Splitter, multiport tap, and combiner all introduce more signal loss compared to a directional coupler.

Question 7

What element is typically NOT part of a paging system?

Accepted Answer

A strobe is typically not part of a paging system, which usually includes distribution, amplification, and loudspeakers for audio transmission.

Question 8

A building has six floors plus a basement. Each floor is 10,000 square feet and has approximately 50 CATV outlets respectively. There is a single hardline trunk cable installed from the basement headend passing through a directional coupler in each floor's telecommunications room (TR). Which leg of the coupler will have the LEAST signal loss?

Accepted Answer

The through leg of the directional coupler will have the least signal loss because it allows the signal to pass through without branching off to other legs. The tap leg will have some signal loss because it diverts some of the signal to a connected device. The splitter leg will also have some signal loss because it splits the signal into two or more outputs. The port leg is not a relevant term in this scenario.

Question 9

You are designing a building with a combination of Class A commercial office spaces and residences. The design program requires having unlimited cable channels available at all outlet locations. What distribution system topology will NOT provide adequate channel distribution to each location?

Accepted Answer

Video over balanced twisted-pair is not suitable for distributing unlimited cable channels because it has limited bandwidth and can only support a limited number of channels.

Question 10

All of the following are true about the post construction phase EXCEPT:

Accepted Answer

The contractor, not the owner, is typically responsible for updating the record copy drawings to reflect "as-built" conditions.

Question 11

At the end of the third week of a project, the actual cost of work performed is $7000 USd and the budgeted cost of work performed is $8000 USd. Which of the following is true?

Accepted Answer

The actual cost of work performed ($7000) is less than the budgeted cost of work performed ($8000), indicating that the project is under budget.

Question 12

The headend has several audio-video playback devices within it. What piece of equipment is required to assign their output signals to specific RF carriers on the CATV system?

Accepted Answer

A modulator is required to assign the output signals from the audio-video playback devices to specific RF carriers on the CATV system. The modulator converts the baseband signals from the playback devices into RF signals that can be combined with other RF signals in the system. Combiners, splitters, and multiport taps are used for other purposes in the CATV system.

Question 13

Exhibit: The following diagram represents what type of CATV distribution system?

Accepted Answer

The answer of Exhibit: The following diagram represents what type...

Question 14

Exhibit: If a work breakdown structure (WBS) shows the tasks below, what is C, the successor task? A) Install OSP pathways B) Install fiber C) ________.

Accepted Answer

The answer of Exhibit: If a work breakdown structure (WBS)...

Question 15

Active video converters are required for what type of CATV distribution system?

Accepted Answer

Active video converters are required for video over balanced twisted-pair systems to convert the video signals for transmission over the twisted-pair cables.

Question 16

An active video converter is used in what type of CATV cable distribution system?

Accepted Answer

The answer of An active video converter is used in...

Question 17

Which of the following is NOT an element of a cable system?

Accepted Answer

Television is not an element of a cable system, as it is the device used by the subscriber to receive the cable signal. The other three choices, Headend, Distribution system, and Subscriber drop, are all elements of a cable system. The headend is the central location where the cable signal is received and processed for distribution. The distribution system is the network of cables that delivers the signal from the headend to the subscriber drop, which is the individual connection point for each subscriber's home or business.

Question 18

A building has a series of CATV outlets each with cables installed back to a telecommunications room (TR), and each telecommunications room (TR) is connected to the headend. What is this type of topology called?

Accepted Answer

The described topology is a Star.

Question 19

You are designing a restaurant located within a retail mall. The ambient noise level of the restaurant is 70 dB. The ambient noise level of the mall common space is 75 dB. What is the MINIMUM sound pressure level (SPL) that should be used when designing the paging system within the restaurant?

Accepted Answer

The minimum SPL for the paging system should be 5 dB higher than the ambient noise level in the restaurant (70 dB). However, it should also be able to overcome the ambient noise level in the mall common space (75 dB). Therefore, the minimum SPL should be 80 dB.

Question 20

Which is NOT a type of contract?

Accepted Answer

There is no such type of contract where mediation panel assigns a fair price based on work completed. The other options are all types of contracts - fixed price, cost-plus fee, and unit price.
