Which choice below most accurately describes SSL?

A.
It’s a widely used standard of securing e-mail at the Application level.

B.
It gives a user remote access to a command prompt across a secure, encrypted session.

C.
It uses two protocols, the Authentication Header and the Encapsulating Security Payload.

D.
It allows an application to have authenticated, encrypted communications across a network.

Explanation:
The Secure Socket Layer (SSL) sits between higher-level
application functions and the TCP/IP stack and provides security to
applications. It includes a variety of encryption algorithms to secure
transmitted data, but the functionality must be integrated into the
application.
Answer “It’s a widely used standard of securing e-mail at the Application level.” refers to the
Secure/Multipurpose Internet Mail Extension (S/MIME). Most major e-mail clients support S/MIME
today.
Answer “It gives a user remote access to a command prompt across a secure, encrypted session.”
describes Secure Shell (SSH).
Answer “It uses two protocols, the Authentication Header and the Encapsulating Security
Payload.” refers to IPSec. IPSec enables security to be built directly into the
TCP/IP stack, without requiring application modification. Source:
