Which three statements correctly describe Session 380280? (Choose three.)

The correct answer is A. The application was initially identified as "ssl." D. The application shifted to "web-browsing." E. The session went through SSL decryption processing.. The session was initially identified as SSL traffic, then underwent decryption, which allowed the firewall to re-identify the underlying application as web-browsing.

Why each option

The session was initially identified as SSL traffic, then underwent decryption, which allowed the firewall to re-identify the underlying application as web-browsing.

AThe application was initially identified as "ssl."Correct

Palo Alto Networks firewalls initially identify encrypted traffic as 'ssl' before decryption can occur to reveal the actual application.

BThe session has ended with the end-reason "unknown."

An 'unknown' end reason typically indicates an issue or abnormal session termination, which is not described as a characteristic of this correctly processed session.

CThe session cid not go through SSL decryption processing.

If the application shifted from 'ssl' to 'web-browsing' after initial identification, it means decryption occurred, making this statement false.

DThe application shifted to "web-browsing."Correct

After successful SSL decryption, the firewall can accurately identify the underlying application, such as 'web-browsing', demonstrating an application shift.

EThe session went through SSL decryption processing.Correct

SSL decryption processing is required for the firewall to inspect the encrypted traffic, perform advanced application identification, and thus allow the application to shift from 'ssl' to 'web-browsing'.
