RCDD (RCDD): Mastering Telecommunications Standards 3

Question 1

Under ANSI/TIA-607, what color is designated for grounding conductors in telecommunications grounding and bonding systems?

Accepted Answer

Green

Answer

ANSI/TIA-607 designates green as the color for grounding conductors in telecommunications bonding and grounding infrastructure.

Question 2

Which standard governs the administration of telecommunications infrastructure, including labeling and record-keeping?

Accepted Answer

ANSI/TIA-606

Answer

ANSI/TIA-606 defines the administration standard for telecommunications infrastructure, covering labeling, records, and reports.

Question 3

What maximum pulling tension is specified by TIA-568 for 4-pair UTP horizontal cable during installation?

Accepted Answer

110 N (25 lbf)

Answer

TIA-568 specifies a maximum pulling tension of 110 N (25 lbf) for 4-pair UTP horizontal cable to prevent stretching and performance degradation.

Question 4

In a TIA-942 data center design, what tier level requires fully redundant subsystems with no single points of failure and 99.995% availability?

Accepted Answer

Tier IV

Answer

Tier IV (per TIA-942) requires fully redundant and fault-tolerant subsystems, delivering 99.995% uptime with no single point of failure.

Question 5

According to ANSI/TIA-568, what is the minimum number of optical fiber strands required in a backbone cable serving a single telecommunications room?

Accepted Answer

6 strands

Answer

TIA-568 requires a minimum of 6 strands of optical fiber in a backbone cable serving a single telecommunications room.
