PCNSA Decryption and Monitoring Practice Question
Which TWO logs are most useful for troubleshooting SSL decryption issues? (Select exactly two.)
⚠ Common exam trap
Watch out — candidates often confuse the Threat log (which shows post-decryption threats) with logs that diagnose the decryption process itself, or mistakenly think GlobalProtect logs are relevant because SSL decryption is sometimes used in VPN environments.

Correct answer & explanation
✓
System log
The System log (B) records decryption-related events, such as certificate validation failures, handshake errors, and unsupported cipher suites, which are critical for diagnosing SSL decryption issues. The Traffic log (D) shows whether traffic was decrypted or bypassed, including the 'Decrypted' flag and details about the SSL/TLS handshake, allowing you to verify decryption policy application.
