, Section 1: Cabling Standards, Codes & Safety (Questions 1–10)
Q1: Which standard series provides the core requirements for commercial building
telecommunications cabling in North America?
A. ANSI/TIA-569
B. ANSI/TIA-607
C. ANSI/TIA-606
D. ANSI/TIA-568 **[CORRECT]**
Correct Answer: D
Rationale: The ANSI/TIA-568 series (including 568.0 through 568.4) defines the cabling
system requirements for commercial buildings. TIA-569 covers pathways and spaces,
TIA-606 covers administration, and TIA-607 covers grounding and bonding.
Q2: A project manager needs to confirm which standard governs the labeling and records for
a new cabling system. Which standard applies?
A. ANSI/TIA-526
B. ANSI/TIA-568
C. ANSI/TIA-598
D. ANSI/TIA-606 **[CORRECT]**
Correct Answer: D
Rationale: Administration, including labeling and record keeping, is covered by the
ANSI/TIA-606 series. TIA-568 addresses cabling performance, TIA-598 addresses fiber
color coding, and TIA-526 addresses test procedures.
Q3: Which document should an installer consult for requirements covering the bonding and
grounding of a telecommunications system?
A. ANSI/TIA-569
B. ANSI/TIA-598
C. ANSI/TIA-606
D. ANSI/TIA-607 **[CORRECT]**
Correct Answer: D
Rationale: ANSI/TIA-607 establishes telecommunications grounding and bonding
requirements, including busbars and bonding conductors. The other standards address
pathways and spaces, fiber color codes, and administration.
