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
✓
TLS 1.2 or higher
TLS (Transport Layer Security) is the standard protocol for encrypting data in transit over networks, such as between a web browser and a server. PCI DSS requires strong encryption for cardholder data in transit.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AES-256
Why it's wrong here
AES-256 is a symmetric key algorithm used for encryption at rest, not typically for transit.
- ✓
TLS 1.2 or higher
Why this is correct
TLS 1.2+ provides secure encryption in transit and is required by PCI DSS.
- ✗
SHA-256
Why it's wrong here
SHA-256 is a hashing algorithm, not for encryption.
- ✗
IPsec VPN
Why it's wrong here
IPsec VPN secures site-to-site connections but is not the standard for web application traffic.
