A system administrator is setting up a web server for an internal development and testing environment. The administrator needs to enable HTTPS to simulate the production environment, but wants to avoid the cost and validation process of a public Certificate Authority (CA). Which of the following certificate types is the most suitable choice for this scenario?
A self-signed certificate is the most appropriate choice for this scenario. Since the server is for internal testing only, public trust from a third-party CA is not required. A self-signed certificate provides the necessary encryption for HTTPS traffic within this closed environment without incurring costs or requiring an external validation process. Wildcard, Extended Validation (EV), and Domain Validation (DV) certificates are all types issued by a trusted third-party CA and are intended for use on public-facing servers where establishing trust for external users is essential.
