B.
Cable tested by an automated tester
C.
Cable tested to both Cat 3 and Cat 5 specifications
D.
Cable tested to "enhanced Cat 5”  or “augmented Cat 6” specifications
 

 2. 

Every UTP link must be first tested for correct connections or "wiremap." What else must be tested?
A.
Attenuation and crosstalk
B.
Attenuation and ACR

Length and ACR

C.
Time domain reflectometer (TDR)
D.
All of the above
 

 4. 

Why is "Powersum NEXT" important in new cable plants?
A.
Higher speed networks need less crosstalk
B.
New networks will have signals on all the pairs in the cable
C.
Cat 5e and Cat 6 cable are more sensitive to crosstalk
D.
It's a marketing issue, not a technical issue
