How does Call Detail Record Agent running on a Cisco Unified Communications Manager node determine if a CDR flat file is ready to be transferred to a designated CDR Repository node?
A. The CDR Agent transfers all new CDR flat files upon receiving notification from the CDR Repository node on the name of last file successfully received
B. The CDR Agent transfers all new CDR flat files generated after the last successful transfer
C. The CDR Agent transfers any CDR flat file before its deletion
D. The CDR Agent transfers all CDR flat files at a specific configurable time of day
E. The CDR Agent knows transfer eligibility from the name of a CDR flat file name
I think the correct answer is C

Likely E
I Think E is the correct answer. According to : https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/service/12_5_1/cdrdef/cucm_b_cdr-admin-guide-1251/cucm_b_cdr-admin-guide-1251_chapter_01.html
As part of the CDRM feature, a resident component on the server or node within a Unified Communications Manager installation acts as the CDR Agent. On the server or node where both Unified Communications Manager and the CDR Agent are running, Unified Communications Manager writes the CDRs into CDR flat files in comma separated value (CSV) format. A special control character (“_”) that is prefixed to the filename by the call processing module that indicates that the file is not available for transfer. If this control character is not present, the system assumes that the file is available for transfer, and the CDR Agent then SFTPs those files to the designated CDR repository node. Upon successful transfer, the system deletes the local copy of the file.
I believe answer is C according to https://community.cisco.com/t5/collaboration-voice-and-video/understanding-cdr-call-detail-records/ta-p/3112476
