Question 129

Refer to the exhibit. An engineer is trying to connect to a device with SSH but cannot connect. The engineer connects by using the console and finds the displayed output when troubleshooting.

Which command must be used in configuration mode to enable SSH on the device?

    Correct Answer: D

    The device output clearly indicates that SSH is disabled because no RSA keys are present. The message '%Please create RSA keys to enable SSH' confirms that generating RSA keys is necessary to enable SSH. Therefore, the correct command to use in configuration mode to enable SSH is 'crypto key generate rsa'.

D, you have to generate the key before enabling ssh

KoumeOption: D

The log states that ssh is disabled because lacks of rsa key pairs. So this is the only answer here.

Mystic13Option: D

You need to generate the rsa keys before you enable sshv2. D is correct

Please read this from ENARSI book where it clearly says SSH enabled so how come our answer is D. It should be C.

Well i will cite the ENARSI book "To check the version of SSH that is running, use the show ip ssh command, as shown in Example 23-5. If it states version 1.99, it means versions 1 and 2 are running. If it states version 1, then SSHv1 is running, and if it states version 2, then SSHv2 is running."
