Where must certificates be installed to encrypt all communication from the Recording Server(s)?

The correct choice emphasizes the necessity of installing certificates on both the Management Server and all Recording Servers to ensure encryption for all communication effectively. This is crucial because the Management Server acts as a central hub that oversees and manages all the Recording Servers. Without having the certificates installed on both types of servers, the secure communication channels established during data transmission could be compromised.

Installing certificates solely on the Recording Servers would not suffice because any communication involving the Management Server would remain unencrypted, potentially exposing sensitive data and communication paths. Similarly, having certificates only on client machines does not address the core need for encryption between servers, while storing them on external storage devices does not facilitate direct encryption of communications.

By placing the certificates appropriately as indicated in the correct choice, you ensure comprehensive security across the entire system, maintaining confidentiality and integrity in communication between all server components involved. This setup is essential in environments where sensitive data is transmitted, such as in systems that record and manage surveillance footage.
