Why each option
A VPN creates an encrypted tunnel over a public network, allowing users to securely access remote resources as if they were on the local network.
A VPN (Virtual Private Network) uses encryption protocols such as IPsec, SSL/TLS, or OpenVPN to create a secure, authenticated tunnel between the client and the remote network. This protects data in transit from eavesdropping and provides authenticated access to remote resources.
FTP (File Transfer Protocol) is used for transferring files and transmits credentials and data in plaintext, providing no security for remote access.
POP3 (Post Office Protocol 3) is an email retrieval protocol and has no function related to granting general remote network access.
DNS (Domain Name System) resolves hostnames to IP addresses and is a name resolution service, not an access or security protocol.
