Final answer:
To enable SSH on a Cisco device, the device must be running a K9 IOS image, which provides cryptographic functionality.
Step-by-step explanation:
To enable SSH on a Cisco device, the device must be running a K9 IOS image, which provides cryptographic functionality. This image includes the necessary Secure Shell (SSH) protocols for secure remote access to the device. SSH encrypts the data being transmitted, ensuring confidentiality and integrity.
The K9 designation in the IOS image indicates the presence of cryptography features, including SSH support. Other options mentioned in the question, such as Universal, Security, Enterprise, and Services, are not specifically related to enabling SSH.
Enabling SSH involves configuring the device with a hostname, generating RSA key pairs for encryption, and enabling the SSH server. Once SSH is enabled, authorized users can securely access the Cisco device remotely over a network.
