When should an order for new modern keys be submitted?

• A. At least 15 days prior to expiration
• B. Within 30 days prior to expiration
• C. At the time of key request
• D. Only after the expiration

Answer: (B)

Submitting an order for new modern keys within 30 days prior to expiration is critical for maintaining continuous communication security. This time frame allows adequate lead time for processing, delivery, and any contingencies that may arise during the transition from old keys to new ones. It ensures that there is no lapse in key availability and helps prevent operational interruptions.

This proactive approach also ensures that personnel can perform necessary updates and testing of new keys without the pressure of impending expiration. Maintaining a routine of ordering keys well in advance contributes to a more secure communications environment and helps mitigate risks associated with key management.
