CompTIA Linux+ (XK0-004) — Question 101

A security administrator wants to display a warning banner before a user logs in. Which of the following files must be edited to make this happen?

Answer options

• A. /etc/services
• B. /etc/issue
• C. /etc/hosts
• D. /etc/motd

Correct answer: B

Explanation

The correct answer is B, as the /etc/issue file is specifically used to display a message before the login prompt. The other options do not serve this purpose: /etc/services is for network services, /etc/hosts is for mapping hostnames to IP addresses, and /etc/motd is displayed after a user logs in, not before.
