After installing a Linux server and activating SSH on it, you try to authenticate, but are rejected
due to an “authentication failure.” You have properly transferred host and public keys, and all of
your servers use the same flavor of SSH (Open SSH). What is a likely cause for your failure to

connect to this newly configured server?

A.
You must first disable Telnet and rlogin for SSH to work properly.

B.
You must first conduct a Telnet session with the server.

C.
The version of SSH you are using is incompatible with your Linux system.

D.
Your name resolution is incorrectly configured.
