D. CCDPSTNFailOverDurationTimeOut
E. CCDLearnedPatternLimitReached
Which alarm string purges all learned patterns from the Cisco Unified Communications Manager?
CCDPSTNFailOverDurationTimeOut
Error Alarm
When learned patterns are not reachable through IP, Cisco Unified Communications Manager routes calls through the PSTN. When this alarm occurs, the PSTN failover duration has expired, and calls to learned patterns cannot be routed. All learned patterns get purged from Cisco Unified Communications Manager.
Troubleshoot your network to get IP connectivity restored. After IP connectivity is restored, Cisco Unified Communications Manager automatically relearns patterns and calls to learned patterns automatically proceed through IP.
CCDLearnedPatternLimitReached
Warning Alarm
This alarm indicates that the CCD requesting service has met the maximum number of allowed learned patterns.
This alarm displays the value that is configured for the parameter, CCD Maximum Numbers of Learned Patterns, as well as the maximum number of learned patterns that are allowed by the system (20,000). Consider whether the specified maximum number of learned patterns is correct for your deployment. If the value is too low, compare it with the number that displays in the SystemLimitCCDLearnedPatterns in this alarm. If the maximum number is below the system limit, which is 20,000 learned patterns, increase the value for the CCD Maximum Numbers of Learned Patterns parameter.
I would choose D
CCDPSTNFailOverDurationTimeOut
When learned patterns are not reachable through IP, Cisco Unified Communications Manager routes calls through the PSTN. When this alarm occurs, the PSTN failover duration has expired, and calls to learned patterns cannot be routed. All learned patterns get purged from Cisco Unified Communications Manager.

CCDPSTNFailOverDurationTimeOut
The internal limit on PSTN failover has expired.
When learned patterns are not reachable through IP, Unified CM routes calls through the PSTN instead. Calls
can be routed through PSTN for an internally-controlled duration. When this alarm occurs, the PSTN failover
duration has exp
