PCNSA Policy Evaluation and Management Practice Question
Match each security rule type to its purpose.
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
✓
Security rule: Controls traffic based on source, destination, application, and service.
Correct matches: Security rule controls traffic based on source/destination/app/service; NAT rule translates IP addresses/ports; Decryption rule decrypts SSL/TLS traffic. Common confusions: QoS rules are for marking and prioritizing traffic, not access control; Application Override rules bypass App-ID, not decrypt traffic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Security rule: Controls traffic based on source, destination, application, and service.
Why this is correct
Security rules are used to permit or deny traffic based on source, destination, application, and service.
- ✓
NAT rule: Translates source and/or destination IP addresses and ports.
Why this is correct
NAT rules perform network address translation to modify IP addresses and ports.
- ✓
Decryption rule: Decrypts SSL/TLS traffic for inspection.
Why this is correct
Decryption rules allow the firewall to decrypt SSL/TLS encrypted traffic to inspect it for threats.
- ✗
QoS rule: Controls traffic based on source, destination, and application.
Why it's wrong here
Incorrect — this describes a Security rule, not a QoS rule. QoS rules set traffic priorities and bandwidth limits.
- ✗
Application Override rule: Decrypts traffic for inspection.
Why it's wrong here
Incorrect — this describes a Decryption rule. Application Override rules bypass App-ID and force a specific application.
