DCI Copper Cable Termination 5

Question 1

When installing a Cat 6 cable through a conduit shared with other Cat 6 cables, which practice reduces crosstalk?

Accepted Answer

Maintaining the cable's twist ratio and not over-bending inside the conduit

Answer

Grounding the conduit at both ends

Answer

Untwisting all pairs before pulling to reduce friction

Answer

Using T568A on all cables in the same conduit

Question 2

A field technician is terminating a high-density Cat 6A panel with 48 ports. Which practice BEST prevents pair damage?

Accepted Answer

Work in small sections and re-dress cables after each block of 12 terminations

Answer

Terminate all cables and then test all ports at once

Answer

Use a Cat 5e punch-down tool to avoid over-compression

Answer

Remove all jacket from the last 100 mm for easier access

Question 3

What is the purpose of maintaining pair twist all the way into the IDC slot on a 110-style block?

Accepted Answer

Minimize near-end crosstalk at the termination point

Answer

Increase pulling tension capacity

Answer

Ensure the correct color is visible for inspection

Answer

Comply with fire-rating requirements

Question 4

Which of the following conditions would cause a 'short' fault reading between pins 3 and 6 on a cable tester?

Accepted Answer

Two conductors touching inside the connector or jack slot

Answer

Incorrect NVP entered on the tester

Answer

Pair 2 terminated as a split pair

Answer

Exceeding the 90 m horizontal cable limit

Question 5

After completing terminations on a 24-port Cat 6 patch panel, the technician should perform which test FIRST?

Accepted Answer

Wire map test on each port

Answer

Full channel certification test

Answer

OTDR sweep

Answer

Insertion loss test only

Question 6

A Cat 6 keystone jack uses a 110-style IDC. A technician forces a conductor into the wrong slot and attempts to reseat it in the correct slot. What is the recommended action?

Accepted Answer

Replace the jack, as re-seating a mis-punched conductor can damage the IDC contacts

Answer

Re-punch the conductor into the correct slot and retest

Answer

Swap the color assignments to match where the conductor was punched

Answer

Apply conductive paste to improve the contact after reseating

Question 7

Which bonding method is required when terminating screened Cat 6A (F/UTP) cable at a patch panel?

Accepted Answer

Connect the foil drain wire to the panel's grounding bar or bonding point

Answer

Tape the foil back against the cable jacket

Answer

Cut the drain wire flush with the jacket

Answer

Leave the drain wire floating and rely on capacitive coupling
