A company wants to provide internal identity verification services for networked devices. Which of the following servers should be installed?

An SSH (Secure Shell) server provides secure remote access and file transfer, but it is not a general-purpose service for broad internal device identity verification.

A VPN (Virtual Private Network) server creates secure, encrypted tunnels over public networks, primarily for remote access, and does not serve as the core service for internal device identity verification.

A Certification Authority (CA) server is essential for internal identity verification as it issues, signs, and manages digital certificates. These certificates allow networked devices to prove their identities to other systems and services within the organization's network, establishing a chain of trust.

A DHCP (Dynamic Host Configuration Protocol) server automatically assigns IP addresses and network configuration, which is unrelated to device identity verification.

A DNS (Domain Name System) server translates domain names to IP addresses, facilitating network communication, but it does not provide identity verification services.
