CompTIA Linux+ XK0-006 (V8) Practice Question

A Linux administrator must secure an Apache knowledge-base server running on CentOS. Management insists that the site be reachable over HTTPS without browser trust warnings, incur no recurring certificate fees, and demand minimal ongoing manual work from the IT staff.

Which solution BEST satisfies all of these requirements?

  • Request a domain-validated certificate from a no-cost publicly trusted CA (for example, Let's Encrypt) using an ACME client and enable automatic renewal.

  • Sign the server certificate with the organization's internal PKI root and instruct every device owner to install the root certificate.

  • Create a self-signed certificate with OpenSSL and email the CA certificate to all users so they can import it manually.

  • Purchase a multi-year wildcard certificate from a commercial certificate authority and install it on the server.
