A.

The correct answer is option B: Set CDR Enabled Flag and CDR Log Calls with Zero Duration Flag to True.

Explanation: Call Detail Records (CDRs) are a feature of Cisco Unified Communications Manager (CUCM) that captures details about calls, including call start and end times, call duration, call direction, and other call-related information. CDRs are generated for every call that passes through CUCM, regardless of whether the call was successful or not.

To ensure compliance with the company's policy of logging all unsuccessful calls that resulted in a reorder tone, the CDR Enabled Flag must be set to True. This enables the generation of CDRs for all calls, including unsuccessful calls that resulted in a reorder tone.

However, in addition to setting the CDR Enabled Flag to True, the CDR Log Calls with Zero Duration Flag must also be set to True. This flag enables the logging of unsuccessful calls that resulted in a reorder tone but had a zero call duration. By default, CUCM does not log calls with zero duration in CDRs, so this flag must be explicitly set to True to ensure compliance with the policy.

Option A (Set CDR Enabled Flag to True) would enable the generation of CDRs for all calls, but it would not log unsuccessful calls that resulted in a reorder tone but had a zero call duration.

Option C (Set CDR Enabled Flag to True and set Call Diagnostics Enabled to Enable Only When CDR Enabled Flag is True) and Option D (Set CDR Enabled Flag to True and set Call Diagnostics Enabled to Enable Regardless of CDR Enabled Flag) are not relevant to the policy requirement of logging unsuccessful calls that resulted in a reorder tone.

Option E (Leave CDR Enabled Flag and Call Diagnostics Enabled to their default settings) would not enable the logging of unsuccessful calls that resulted in a reorder tone but had a zero call duration.
