What are two characteristics of SSH? (Choose two.)

While SSH is a very common remote-access method, stating it is 'the most common' is subjective and may vary by environment (e.g., RDP for Windows); its security and port are more definitive characteristics.

SSH stands for Secure Shell and is specifically designed to be secured through encryption, making 'unsecured' an incorrect characteristic.

SSH encrypts all traffic exchanged between the client and server, protecting sensitive information like usernames, passwords, and data from eavesdropping.

By default, SSH uses TCP port 22 for establishing secure connections, making it a well-known service port for secure remote access.

SSH operates primarily at the application layer, using TCP (a transport layer protocol) to establish its secure communication channel, rather than operating at the transport layer itself.
