Q3 Single choice

A technician discovers that an Ethernet Routing Switch (ERS) 8300 cat5e copper link is intermittent. The link connects a distant workstation to 8348GTX port 6/2. The cable path is undetermined at this point and it is suspected to traverse many patch panels.

How can the ERS 8300 Time Domain reflectometer tool be of help in this situation?

A
The Virtual Circuit Test command config ethernet 6/2 vct test can detect opens, shorts, bad terminations.
B
The virtual circuit Repair command config ethernet 6/2 vct repair can detect the bad cable pairs and repair the cable by moving data to the good cable pairs.
C
The Virtual Circuit Echo command config ethernet 6/2 vct echo can detect the bad cable pairs only when connected to another ERS 8300.
D
The Virtual Circuit Detect command config ethernet 6/2 vct detect can detect how many patch panels are used between the device and switch and provide a percentage of dropped packets.
