A Chief Information Security Officer (CISO) for a school district wants to enable SSL to protect all of the public-facing servers in the domain. Which of the following is a secure solution that is the MOST cost effective?

Answer options

• A. Create and install a self-signed certificate on each of the servers in the domain.
• B. Purchase a load balancer and install a single certificate on the load balancer.
• C. Purchase a wildcard certificate and implement it on every server.
• D. Purchase individual certificates and apply them to the individual servers.

Correct answer: A

Explanation

The correct answer is A because using self-signed certificates is the most cost-efficient method for securing multiple servers without incurring expenses for purchasing certificates. Options B, C, and D involve additional costs either for hardware or for multiple certificates, making them less economical.
