C. 24.0 dB

D. 10.0 dB

2.After network cabling runs are installed, which of the following tasks needs to be completed?

A. The cable needs to be color-coded and labeled.

B. The cable runs need to be tested.

C. The client needs to sign off on the installation.

D. Service loops need to be installed.

3. What's the minimum cable test required for twisted-pair cable used in voice applications?

B. Delay skew

C. Attenuation

D. NEXT

4.Which of the following tools is used with an amplifier probe to find a specific copper cable in a large bundle of cables?

A. Continuity tester

B. Voltage meter

C. Tone generator

D. Fish tape

5. How many days prior to an installation should cutover preparation begin?

A. 3 to 5 days

B. 1 to 3 days

C. 15 to 30 days

D. 5 to 15 days

Answer 1

1.)Sol. The maximum insertion loss is 18.6dB according to the given standard condition. This is te default standardization of this cable. Therefore, option (B) satisfies here.

2.)Sol. After the installation is completed, then for safety measures the cable runs need to be tested once again & then the client needs to sign off on installation after full inspection. Therefore, option (B) & option (C) both satisfies here.

3.)Sol. The minimum cable test required is check on attenuation as it is the most important factor for voice applications. It provides power to the signal and without it the signal strength would be veey less. Therefore, option (C) satisfies here.

4.)Sol. The tool which is used with an Amplifier probe to find specific copper cable in a large bundle of cables is Fish tape as it allows to pull specific targeted wires very easily. Therefore, option (D) satisfies here.

5.)Sol. The cuttover testing plan should be implemented 5-15 days prior to the cable installation since it is required for the safety purpose and various other kinds of quality check of the cables. Therefore, option (D) satisfies here.
