What must be done to allow remote access to a device via SSH?

To allow remote access to a device via SSH, it is essential to ensure that SSH is enabled and configured properly. SSH, or Secure Shell, is a network protocol that provides a secure method for accessing a device over an unsecured network.

Enabling SSH on a device typically involves configuring the SSH server settings, which may include specifying authentication methods (like password or key-based authentication), assigning port numbers, and ensuring the device is set to accept incoming SSH connections. Proper configuration also often requires setting firewall rules to allow traffic on the designated SSH port, typically port 22.

Other options do not directly pertain to SSH and remote access. For instance, configuring static routing is concerned with directing packets efficiently through a network but does not specifically address SSH access. Broadcasting refers to sending data packets to all devices on a network segment, which is unrelated to secure remote access protocols like SSH. Setting up a VPN connection is a separate method of securing remote access but does not necessarily involve SSH unless you are tunneling SSH traffic through the VPN. Thus, proper setup and configuration of SSH is the key requirement for enabling remote access via this protocol.
