Which two configuration items are required when the NGFW needs to act as a decryption...

When configuring the NGFW to act as a decryption broker for multiple transparent bridge security chains, the following items are required:

A unique Transparent Bridge Decryption Forwarding Profile to a single Decryption policy rule (B): Each decryption policy rule must be associated with a unique Transparent Bridge Decryption Forwarding Profile. This ensures that decrypted traffic is forwarded appropriately to the specific security chain.

A unique Decryption policy rule is required per security chain (C): You need to create a separate decryption policy rule for each security chain. This allows you to distribute the decrypted traffic among multiple security chains based on policy criteria.

These configurations enable the firewall to effectively manage and distribute the load across multiple security chains, ensuring optimal performance and security​ (Palo Alto Networks)​​ (Palo Alto Networks)
