Load (LD) mode is used to load COMSEC and TRANSEC variables from an external Type-1 fill device.

• A. Reset device
• B. Load COMSEC and TRANSEC variables from an external Type-1 fill device
• C. Power on
• D. Transmit data

Answer: (B)

LD mode is the designated state for bringing in new cryptographic material. It’s the mode used to import COMSEC and TRANSEC variables from an external Type-1 fill device into the secure crypto device, so it has current keys and settings needed to protect communications. This is what the load operation is for—to load key material from a trusted device. The other options don’t perform this function. Resetting would return the device to a baseline state without loading new key material. Powering on initializes hardware but doesn’t import keys. Transmitting data would send information, not load or update the cryptographic variables.
