Question 9: Certkiller .com has reported that some local calls are NOT going through (the caller hears
no ringing, etc.). Which two tools can the technician use to determine which trunk is
responsible? (Choose two.)
A. Use LD 80, to trace the DN of the telephone with the problem call. While the problem is
occurring, the output will identify the TN of the trunk for further testing.
B. Use LD 36, to list threshold overflows for the local route. Look for trunks with excessive
short holds and conduct further testing on those trunks using the TRK command in Load 36.
C. Use LD 80, to initiate a Malicious Call Trace (MCT) on the DN reporting the problem for the
date and time indicated in the problem report. This will identify the TN of the trunk involved.
D. Use LD 40, Call Detail Recording Diagnostic, to trace call history for the DN of the user
reporting the problem. From the CDR records output, correlate the call record time with the time
of the users problem call. The matching CDR record will identify the TN of the trunk that should
be tested.
