For enabling SSH with cryptographic functionality on a Cisco device, the device must run which IOS image?

• A. K9
• B. K5
• C. L9
• D. K7

Answer: (A)

To run SSH with cryptographic functionality, the device needs an IOS image that includes the cryptographic libraries used by SSH. In Cisco naming, that means the K9 image, which provides the strong, built-in crypto features required for SSH and other encrypted services. Without the K9 crypto image, the device lacks the necessary cryptographic support, so SSH cannot be enabled. The other image options either offer only weaker export-grade crypto or are not configured to include the crypto libraries needed for SSH, so they won’t meet this requirement.
