SSH Version 2 is recommended for secure remote access due to its enhanced security features and improvements over its predecessor, SSH Version 1. SSH Version 2 provides stronger authentication, better integrity, and encryption algorithms, thus ensuring a more secure connection.

This version introduces support for more advanced authentication methods, such as public key authentication and the Diffie-Hellman key exchange algorithm, which helps in establishing a shared secret securely. Additionally, SSH Version 2 includes mechanisms to prevent "man-in-the-middle" attacks and has improved protections against replay attacks.

SSH Version 1, while functional, is considered less secure as it has known vulnerabilities and lacks many of the features that make Version 2 robust. Telnet does not provide any encryption for data in transit and transmits sensitive information, such as usernames and passwords, in plaintext, making it unsuitable for secure remote administration. There is currently no widely recognized SSH Version 3, which does not exist as a standard, meaning that that answer is not relevant in this context. Thus, SSH Version 2 stands as the best choice for secure remote access.
