When horizontal cabling must be adapted to accommodate specific user needs make the adaptions inside the telecommunications outlet/connector or MUTOA.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement is false because when horizontal cabling needs to be adapted to accommodate specific user needs, the adaptations should be made outside of the telecommunications outlet/connector or MUTOA. This is because the telecommunications outlet/connector or MUTOA should remain standardized and not be modified. Any adaptations or changes should be made in the patch panel or patch cords, which are easily replaceable and can be customized to meet specific user needs.

The maximum size pathway must not force the cable bend radius to be less than ___ in under conditions of maximum cable fill?
- A.
  
  2 in
- B.
  
  1 in
- C.
  
  3 in
- D.
  
  1.5 in
Correct Answer
B. 1 in

Explanation
The maximum size pathway must not force the cable bend radius to be less than 1 in under conditions of maximum cable fill. This means that when the pathway is filled with the maximum number of cables, the bend radius of the cables should not be less than 1 inch. This is important to ensure that the cables are not bent too tightly, which can cause damage to the cables and affect their performance.
