How many crypto fills can the AN/CYZ10 store?

The AN/CYZ-10, also known as the Data Transfer Device (DTD), is specifically designed to securely load and transfer cryptographic keying material and other data. One of its key features is its capability to store a significant number of cryptographic fills.

The correct answer indicates that the AN/CYZ-10 can store over 1,000 crypto fills, which aligns with its intended use in managing large amounts of encryption data for tactical operations. This high capacity is essential for military communications, allowing for a more versatile and robust operational capability in secure communications.

Considering the other options, while over 500, over 2,000, and over 3,000 may seem plausible, they do not accurately reflect the specific capabilities of the AN/CYZ-10 as established in military specifications. Hence, the fact that it is designed to securely manage over 1,000 crypto fills is a clear demonstration of its advanced functionality within the context of military communications infrastructure.
