CompTIA Security+ (SY0-501) — Question 578

A systems administrator needs to install the same X.509 certificate on multiple servers. Which of the following should the administrator use?

Answer options

• A. Key escrow
• B. A self-signed certificate
• C. Certificate chaining
• D. An extended validation certificate

Correct answer: D

Explanation

The correct answer is D, an extended validation certificate, as it is designed for use across multiple servers while providing a higher level of trust. Options A, B, and C are not suitable for this scenario; key escrow is related to key management, a self-signed certificate typically lacks the trust needed for public-facing servers, and certificate chaining is a method of linking certificates rather than a certificate type for installation.
