Registered Communications Distribution Designer (RCDD-001) — Question 8

You have determined that the equipment room (ER) you are designing will be the minimum size of 15 sq m (160 sq ft) and is servicing 80 but architectural changes will add 175 , which will require you to add a horizontal cross-connect (HC). What size should the equipment room (ER) be?

Answer options

• A. 18 sq m (193 sq ft)
• B. 23 sq m (250 sq ft)
• C. 31 sq m (330 sq ft)
• D. 37 sq m (400 sq ft)
• E. 47 sq m (500 sq ft)

Correct answer: A

Explanation

The correct answer is A, which provides a minimum size of 18 sq m (193 sq ft) to accommodate the new capacity requirements after the architectural changes. The other options (B, C, D, E) represent sizes that exceed the additional needs based on the calculation of space required for 255 total connections, making them unnecessarily large.
