Which of the following would allow remote users to access a corporate server? (Choose two.)

A VPN server allows remote users to establish an encrypted tunnel into the corporate network, granting access to internal resources as though the user were physically on-site.

SMTP is the Simple Mail Transfer Protocol used for routing email between mail servers; it does not provide interactive remote access to a corporate server.

NTP (Network Time Protocol) synchronizes clocks across networked devices and has no capability to provide remote login or access to a server.

An SSH server provides encrypted, authenticated remote shell and command-line access, allowing users to securely log in and manage a server across any network.

DHCP dynamically assigns IP addresses and network configuration to clients; it provides no mechanism for authenticating or granting remote access to a server.

A file server provides shared storage access but does not inherently provide remote shell or administrative access to the underlying server operating system.
