Which of the following will provide the ability to access these devices?

Answer options

Correct answer: B

Explanation

The correct answer is B, SSH, as it provides secure encrypted communications for accessing network devices over an unsecured network.

RDP (C) and VNC (D) are primarily used for remote desktop access rather than direct device management, making them less suitable for this purpose.
