NCIDQ IDFX EXAM/47 Q’S AND A’SThe principal consideration in acoustic control in large spaces is the sound
absorptive quality of the ________. - -Ceiling
[Noise reduction within a space: In larger rooms, ceiling treatment is most
effective, while in smaller rooms, wall treatment is more effective.]
-These are part of the HVAC system used for return air and generally have
no movable parts or slats for adjustment. - -Vents

Systems
-Diffusers have direction fins at different angles (sometimes adjustable) to
distribute the air throughout the space.
-Registers (in the floor or wall) can be open, closed, or adjusted somewhere
in-between.
-Grilles often used for return air have no movable parts or slats for
adjustment.]
-In a new lifestyle hotel, the spa suites will have 4 poster canopy beds. How
far away from the sprinkler heads should the beds and panels be? - -20
inches
[The canopy would be considered an obstruction to discharge as defined in
NFPA 13, 8.5.5 Obstructions to Sprinkler Discharge, which restricts
continuous or noncontinuous obstructions less than or equal to 18in
(450mm) below the sprinkler deflector.]
-What are the variables of noise reduction between two rooms? - -The three
most important variables are the wall's stiffness, the transmission loss, and
the common area between rooms.
-A client has requested that special security protection be provided for
critical paper files containing corporate trade secrets, but at a reasonable
cost.
In designing the file room, the interior designer should suggest: - -Card
readers at the doors leading to the file room
[Source: Interior Construction Detailing for Designers, Hardware, Electronic
Hardware
Card readers would be the most cost-effective solution because they could
provide access control as well as notification if there was an attempt at
unauthorized entry.]
-An air handler access panel should measure a minimum of: - -2' x 2' (600
mm x 600 mm)
[Source: Interior Construction Detailing for Designers, Ceilings
, -Building codes require that access panels be provided to certain
components of the mechanical and electrical systems for anything that has
to be inspected, adjusted or repaired. Access doors are typically small steel
doors with frames that are opened by using a thumb turn or a key.
-Per the NCIDQ instructions in a typical commercial reflected ceiling plan
demonstrating integration of building systems, the candidate is to place a
minimum 2' x 2' (600 mm x 600 mm) access panel for the air handling unit
where required.]

-All buildings move to some extent, what type of joint is used accommodate
large movements and are typically part of the building design? - -expansion
joints
[All buildings move to some extent. Interior construction must take into
account the possible movement of the building structure. Slip joints and
relief joints should be used whenever minor building movement is expected.
Large movements are accommodated by building expansion joints, but these
are usually already in place as part of the design of the building.]
-Which type of door typically used in commercial construction contains one
or more glass lights? - -sash
[Metal doors and frames (often referred to as hollow metal) are seldom used
for residential construction. They are, however, frequently used in
commercial construction because of their durability, security, and fire-
resistive qualities.
The three most common types of metal doors are flush, sash and louvered.
Flush doors have a single smooth surface on both sides. Sash doors contain
one or more glass lights. Louvered doors have an opening with metal slats to
provide ventilation.]
-Which of the following would be the correct way to number a fire protection
plan in a set of construction drawings for a high rise office space? - -5FP4.1
