VDV Testing and Certification 5

Question 1

Which organization awards the BICSI RCDD (Registered Communications Distribution Designer) credential that is closely associated with VDV system design standards?

Accepted Answer

BICSI

Answer

BICSI (Building Industry Consulting Service International) administers the RCDD credential, which validates expertise in ICT systems design and distribution.

Question 2

A technician measures an ACR-F (Attenuation to Crosstalk Ratio — Far End) of 5 dB on a Cat 6 link. What does this indicate?

Accepted Answer

Poor performance; the crosstalk at the far end is only 5 dB below the signal level

Answer

ACR-F of only 5 dB means the far-end crosstalk is nearly as strong as the attenuated signal, leaving very little headroom and indicating poor link performance.

Question 3

When testing a structured cabling system, what does the autotest feature of a certified cable analyzer do?

Accepted Answer

Runs all required tests for the selected standard and compares results to pass/fail limits automatically

Answer

The autotest feature runs the complete suite of measurements required by the selected standard (e.g., TIA-568-C.2 Cat 6) and automatically evaluates each result against the defined pass/fail limits.

Question 4

What is the purpose of an optical light source calibration reference measurement (reference method) before conducting fiber insertion loss tests?

Accepted Answer

To establish a baseline 0 dB reference so link losses are measured relative to a known starting point

Answer

The reference measurement establishes the starting power level (0 dB reference) so all subsequent loss measurements represent actual attenuation relative to a known input.

Question 5

A VDV technician documents test results and stores them in a certification report. Which information is typically NOT required in a cable certification report?

Accepted Answer

Installer's personal home address

Answer

Certification reports require test data, equipment identification, calibration dates, and cable IDs, but personal contact details like home addresses are not part of the standard documentation.
