A VPN establishes an encrypted channel that keeps a user's identity and access credentials, as well as any data transferred, inaccessible to hackers.
What is a connectionless protocol that offers speed and low overhead?Explanation. User Datagram Protocol (UDP) is a connectionless protocol that is built for speed. It has low overhead and often sends data in small blocks, such as 512 bytes, and its header 8 bytes long.
What benefits does the Domain Name System DNS provide check all that apply?The benefits of DNS are that domain names: can map to a new IP address if the host's IP address changes. are easier to remember than an IP address. allow organizations to use a domain name hierarchy that is independent of any IP address assignment.
