QuestionQ29

Networking

Which of the following is related to the creation of a secured communication channel between workstations in different locations and is supported by credentials for authentication?

Explanation

A VPN (Virtual Private Network) creates a secured, encrypted communication channel between remote workstations in different geographic locations and authenticates users via credentials. DHCP assigns IP addresses, CNAME is a DNS record type, and VLAN segments a local network—none provide remote secure tunneling with credential-based authentication.
