A. B. C. D.


DTLS stands for Datagram Transport Layer Security, and it is a protocol that provides secure communications for datagram protocols such as User Datagram Protocol (UDP). DTLS is very similar to TLS, but it is designed to work with datagram protocols, which are connectionless and have a higher degree of unreliability than TCP.

DTLS is used for delay-sensitive applications, such as voice or video, because it provides a faster handshake than TLS and because it supports retransmissions, which can help mitigate the effects of packet loss. When used for voice or video, DTLS can help reduce latency and improve the overall quality of the communication.

Option A is the correct answer, as delay-sensitive applications are the primary use case for DTLS.

Option B is not correct because DTLS is not designed for double encryption, and using double encryption can actually introduce additional latency and decrease the quality of the communication.

Option C is not correct because DTLS can be used with any topology, and it is not specific to point-to-multipoint.

Option D is not correct because applications that cannot use TLS will also be unable to use DTLS, as DTLS is a variant of TLS designed for datagram protocols.
