Which document contains a list and description of records along with their retention periodicity?

• A. Annex T of EKMS 1B
• B. OPNAVINST 2221.3
• C. SECNAV M5510.30
• D. COMDTINST 5510.3

Answer: (A)

The correct answer is found in Annex T of EKMS 1B, which specifically addresses the management of COMSEC keying material and includes a detailed list and description of records along with their retention periodicity. This document is crucial for ensuring compliance with established guidelines for maintaining the security and integrity of communication materials. It provides clear directives on how long records should be retained, which is essential for both operational effectiveness and legal compliance.

The other options do not focus specifically on the retention of records related to COMSEC and do not provide the same level of detail as Annex T of EKMS 1B. OPNAVINST 2221.3 is more focused on Navy operational policies, while SECNAV M5510.30 deals with the handling of classified information in general. COMDTINST 5510.3 pertains to the Coast Guard's policies on safeguarding and handling classified information but does not specifically address the retention periodicity of COMSEC records.
