Which of the following statements is true regarding Deep Security Relays?

Deep Security Relays are specialized agents that distribute security updates (such as anti-malware patterns, rules, and engine updates) to other agents within the network. Regular Deep Security Agents connect to Relays to receive these updates, reducing the load on the Deep Security Manager and external bandwidth usage.

From the official documentation:

"Relays are agents that download security updates from the Trend Micro Update Server or the Deep Security Manager and then distribute these updates to other agents on the network."

Option D is correct: Agents communicate with relays to obtain security updates.

Option A is incorrect: Only 64-bit agents can be promoted to relays in recent versions.

Option B is incorrect: Relays retain all protection module functions after being promoted.

Option C is partially correct but not as precise as D; relays distribute, but do not "process" requests in the sense of approving/handling agent-side logic.
