CompTIA Security+ (SY0-701) — Question 243

A security administrator is working to find a cost-effective solution to implement certificates for a large number of domains and subdomains owned by the company. Which of the following types of certificates should the administrator implement?

Answer options

Correct answer: A

Explanation

The correct choice is a Wildcard certificate because it allows the administrator to secure a main domain and all its subdomains with a single certificate, making it a cost-effective solution. Client certificates are used for user authentication, self-signed certificates are not trusted by browsers and require manual distribution, and code signing certificates are intended for ensuring the integrity of software rather than securing domains.
