SSCP Network and Communications Security Practice Question
Which of the following is a primary advantage of using TLS 1.3 over earlier versions?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Mandatory forward secrecy
TLS 1.3 requires forward secrecy for all cipher suites, meaning that session keys are not derived from the server's private key, protecting past sessions if the private key is compromised.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Mandatory forward secrecy
Why this is correct
All TLS 1.3 cipher suites use ephemeral Diffie-Hellman, providing forward secrecy.
- ✗
Reduced handshake latency with 0-RTT
Why it's wrong here
0-RTT is a feature but not the primary advantage; forward secrecy is a key security improvement.
- ✗
Support for RC4 cipher suites
Why it's wrong here
TLS 1.3 removes all weak ciphers, including RC4.
- ✗
Backward compatibility with SSL 3.0
Why it's wrong here
TLS 1.3 is not backward compatible with SSL.

Same concept, more angles
1 more way this is tested on SSCP
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A security analyst is reviewing a TLS 1.3 deployment. Which THREE of the following are features of TLS 1.3?
hard- A.Use of static RSA key exchange
- ✓ B.Mandatory forward secrecy
- ✓ C.Support for 0-RTT handshake
- ✓ D.Removal of cipher suites like RC4 and DES
- E.Support for SSL 3.0 compatibility
Why B: TLS 1.3 removed vulnerable cipher suites, mandates forward secrecy, and supports 0-RTT for faster handshakes.
