Exam 1: BICSI Registered Communications Distribution Designer - RCDD

Where backbone cabling exceeds cabling lengths for the same performance or design (for product used in horizontal cabling), there are three fundamental tests which should be considered when testing. They are:

In a telecommunications room (TR), the MINIMUM bottom edge height recommendation for mounting plywood on the wall is ________ above AFF.

What does ANSI/TIA 942 recommend as the MINIMUM height for overhead cable tray above finished floor within a data center?

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?

The recommended ratio of patch panels to horizontal cable management panels is ________ RU of patch panel to ________ rack unit (RU) of horizontal cable management panel.

Which wireless device should be used to support 3 computers and a printer?

What is the International Organization for Standardization/International Electrotechnical Commission ISO/IEC class rating for American National Standards Institute/Telecommunication Industry Association (ANSI/TIA) Category 5e cable?

You are designing a horizontal pathway system where you will provide 100 mm (4 in) conduit and pull boxes. The building architectural elements will only allow for a single layer of conduits (not stacked). The main horizontal pathway system consists of five 100 mm (4 in) conduits. Large single sheath copper cables are not expected to be placed. Which of the following is the MINIMUM width pull box that is to be provided?

What is at the "root" of a DAS (distributive antenna system)?

You are reviewing a building backbone design with a vertically aligned telecommunications room (TR). In the spec you note in a footnote with details that the slots at one end of the telecommunications room (TR) must be flush with the floor and the sleeves provide at the end of the telecommunications room (TR) must also be flush. In your meeting with the electrical engineering firm that has provided the spec, you make the comment that according to best practices, the MINIMUM that slots and sleeves must extend above the finished floor are:

When designing a campus distribution system involving small buildings with only one horizontal cross-connect (HC) [Floor distributor (FD)] per building, you can eliminate the need for a(n):

What is the MINIMUM ceiling height of a telecommunications room?

What is the MINIMUM vertical separation between the top rail of a railroad track and telecommunications facilities placed beneath the track?

Generating multiple message frames containing identical data being transferred to different individual devices is called:

Which of the following is an undesirable electromagnetic effect on a device(s)?

Exhibit: This diagram illustrates an example of a:

In the ceiling zone method of distribution, the usable floor area should be divided into zones each measuring:

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?

When installing underground entrances, no more than ________ 90-degree bends should be included between pulling points.

A fire ________ is a contained area that is completely enclosed by fire resistant walls, floors, and ceilings.
