Oracle Solaris 11 Advanced System Administrator — Question 18

User jack logs in to host solaris and then attempts to log in to host oracle using ssh. He receives the following error message:
The authenticity of host oracle (192.168.1.22) can't be established. RSA key fingerprint is 3B:23:a5:6d:ad:a5:76:83:9c:c3:c4:55:a5:18:98:a6
Are you sure you want to continue connecting (yes/no)?
Which two are true?

Answer options

• A. The public host key supplied by solaria is not known to the host oracle.
• B. The error would not occur if the RSA key fingerprint shown in the error message was added to the /etc/ssh/known_hosts file on solaris.
• C. The private host key supplied by oracle is not known to solaris.
• D. If jack answers yes, the RSA public key for the host oracle will be added to the known_hosts file for the user jack.
• E. The public host key supplied by oracle is not known to the host solaris.

Correct answer: B, D

Explanation

Option B is correct because adding the RSA key fingerprint to the /etc/ssh/known_hosts file on solaris would prevent the authenticity warning. Option D is also correct as confirming the connection will save the RSA public key to jack's known_hosts file. The other options are incorrect because they either misstate the relationship between the hosts' keys or incorrectly describe the nature of the error message.
