A virtual (71) network, or VPN, is an encrypted connection over the Internet from a device to a network. The encrypted connection helps ensure that sensitive data is safely (72). It prevents (73) people fromeavesdropping on the traffic and allows the user to conduct work remotely. Traffic on the virtual network is sent securely by establishing an encrypted connection across the Internet known as a (74).A remote access VPN securely connects a device outside the corporate office. A site-to-site VPN connects the corporate office to branch offices over the Internet. Site-to-site VPNs are used when distance makes it impractical to have direct network connections between these offices. Think of site-to-site access as (75) to network.
A.encodedB.encryptedC.storedD.transmitted
