DCI Standards & Codes Compliance 2 — Questions and Answers
Question 1: Which ANSI/TIA standard specifically addresses cabling infrastructure for healthcare facilities?
- ANSI/TIA-1179 (Correct answer)
- ANSI/TIA-568.2-D
- ANSI/TIA-862-B
- ANSI/TIA-942-B
Correct answer: ANSI/TIA-1179
ANSI/TIA-1179 covers telecommunications infrastructure for healthcare facilities including hospitals and clinics.
Question 2: Under NEC Article 800, communications cables installed in a plenum space must be rated as:
- CMR (Riser)
- CM (Communications Multipurpose)
- CMP (Plenum) (Correct answer)
- CMX (Limited Use)
Correct answer: CMP (Plenum)
NEC Article 800 requires CMP-rated cables in plenum air-handling spaces due to their low smoke and flame-spread properties.
Question 3: The minimum bend radius for a 4-pair UTP horizontal cable during installation (under tension) is typically:
- 4 times the cable diameter
- 8 times the cable diameter (Correct answer)
- 10 times the cable diameter
- 2 times the cable diameter
Correct answer: 8 times the cable diameter
TIA-568 specifies a minimum bend radius of 8 times the cable outer diameter when pulling force is applied during installation.
Question 4: BICSI TDMM is best described as:
- A mandatory federal cabling law
- An industry best-practice reference manual for telecommunications distribution (Correct answer)
- A fire code for data centers
- A UL listing requirement for cable trays
Correct answer: An industry best-practice reference manual for telecommunications distribution
BICSI's Telecommunications Distribution Methods Manual (TDMM) is an industry reference guide, not a mandatory code.
Question 5: Which standard defines the structured cabling requirements specifically for data centers?
- ANSI/TIA-568.3-D
- ANSI/TIA-942-B (Correct answer)
- ANSI/TIA-862-B
- ANSI/TIA-1005-A
Correct answer: ANSI/TIA-942-B
ANSI/TIA-942-B establishes telecommunications infrastructure standards for data centers.
Question 6: Per OSHA regulations, a ladder must extend at least how far above the top landing when used for roof or elevated access?
- 1 foot
- 2 feet
- 3 feet (Correct answer)
- 4 feet
Correct answer: 3 feet
OSHA 29 CFR 1926.1053 requires portable ladders to extend at least 3 feet above the upper landing surface.
Question 7: The TIA-568 standard classifies channel performance categories. Category 6A supports a bandwidth of up to:
- 100 MHz
- 250 MHz
- 500 MHz (Correct answer)
- 750 MHz
Correct answer: 500 MHz
Category 6A (Augmented) supports frequencies up to 500 MHz, enabling 10GBASE-T over 100 meters.
