Digital certificates are typically used to secure communications with which type of entity?

• A. Email clients
• B. Web servers
• C. Wireless access points
• D. Printers

Answer: (B)

Digital certificates enable authentication and encryption over networks using TLS. The most common scenario is when you connect to a website: the web server presents its certificate, your client verifies it against trusted authorities, and a secure, encrypted channel is established for the communication. That widespread, everyday use makes web servers the typical target for digital certificates.

Other options exist in specialized contexts—email clients can use certificates for securing messages or TLS connections, wireless access points can use certificates for 802.1X authentication, and printers may use certificates for secure management—but these are not as universal as securing standard web traffic.
