VPN Concentrator Protocol for Encryption over UDP

A network technician is configuring user access to a VPN concentrator and has been advised to use a protocol that supports encryption over UDP.

Which of the following protocols has the technician MOST likely configured for client use?

A.

TFTP

B.

DTLS

C.

DNS

D.

SNMP.

B.

The protocol that the network technician has most likely configured for client use is DTLS (Datagram Transport Layer Security).

DTLS is a protocol that supports encryption over UDP (User Datagram Protocol). UDP is a protocol that provides a lightweight way to send packets of data over a network, but it doesn't have any built-in security features. By using DTLS with UDP, the network technician can provide encryption and secure communication between the VPN concentrator and the client devices.

TFTP (Trivial File Transfer Protocol) is a protocol that is used to transfer files between network devices, but it doesn't provide any encryption or security features. It is not a suitable protocol for secure VPN communication.

DNS (Domain Name System) is a protocol that is used to translate domain names into IP addresses. It is not used for VPN communication or encryption.

SNMP (Simple Network Management Protocol) is a protocol that is used to monitor and manage network devices. It is not used for VPN communication or encryption.

In summary, the network technician is most likely using DTLS as the protocol to provide encryption over UDP for secure VPN communication.
