Which of the following is a feature of TLS v1.3?

TLS v1.3 introduces several improvements over its predecessor, TLS v1.2, one of which is indeed increased connection speed. This enhancement is primarily due to the reduction in the number of round trips required to establish a secure connection. TLS v1.3 streamlines the handshake process, allowing clients and servers to communicate securely with less latency. By eliminating certain legacy features and options, it simplifies the handshake, resulting in a quicker connection establishment.

The design of TLS v1.3 also focuses on enhancing security by dropping outdated encryption methods and protocols that were considered vulnerable. This focus on modern cryptographic practices means that legacy support or older encryption methods are not applicable within TLS v1.3, which is another reason why the other choices are not accurate.

Through this modernization and efficiency, TLS v1.3 not only achieves faster connections but also aims to provide robust security in today’s evolving threat landscape.
