Which three protocols could an NSX administrator use to transfer log messages to a remote log server?

A network administrator can utilize the TLS protocol to securely transfer log messages to a remote log server when working with NSX. TLS, or Transport Layer Security, is a standard security protocol that ensures data privacy and integrity during transmission. It encrypts the log messages, providing protection against eavesdropping and data tampering, which is essential when sensitive information is involved.

While other options might be relevant in different contexts, they do not serve the same purpose as a secure logging protocol. For example, SSL is an older protocol that TLS has largely replaced due to known vulnerabilities. HTTPS is primarily an application-layer protocol, mainly used for secure web browsing, rather than directly applicable for log message transfer. UDP, on the other hand, is a transport-layer protocol that can be fast and lightweight, but it does not provide any built-in security features, making it unsuitable for securely transmitting log messages where data integrity and confidentiality are critical.

Using TLS for transferring log messages thus ensures the information is handled in a secure manner, aligning with best practices for logging and monitoring in a secure IT infrastructure.
