- A
Create a decryption policy rule with a condition matching the client certificate.
Why wrong: Decryption policies do not support matching on client certificates.
- B
Create a decryption policy rule that excludes the financial application based on URL category.
Why wrong: URL categories are broader and may not precisely match the financial application. The application-based approach is more accurate.
- C
Use an SSL Forward Proxy decryption profile with 'Exclude Certificate' list.
Why wrong: The 'Exclude Certificate' list is for server certificates, not client certificates.
- D
Use a decryption policy rule with 'No Decrypt' action for the financial application.
Correct: This directly excludes traffic identified as the financial application from decryption.
Question 484 of 516
Best Approach to Exclude Financial Transactions from SSL Decryption
This PCNSE practice question tests your understanding of securing traffic and app-id. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A security team is deploying SSL Decryption for inbound traffic to protect against threats hidden in encrypted traffic. However, they want to exclude financial transactions that use client certificates for authentication. What is the best approach?

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
✓
Use a decryption policy rule with 'No Decrypt' action for the financial application.
Option D is correct because the security team needs to exclude specific traffic from SSL decryption without blocking it. A 'No Decrypt' action in a decryption policy rule allows the firewall to bypass decryption for matched traffic while still permitting it to pass through. This is the standard method for excluding sensitive traffic like financial transactions that use client certificates for authentication, as it avoids breaking mutual authentication or violating compliance requirements.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the 'Exclude Certificate' list (which excludes specific server certificates from decryption) with the need to exclude traffic based on client certificate authentication, leading them to incorrectly choose Option C.
Detailed technical explanation
How to think about this question
SSL decryption in Palo Alto Networks firewalls uses decryption policy rules to determine which traffic to decrypt, with actions like 'Decrypt' (forward proxy or inbound inspection) or 'No Decrypt'. For inbound traffic (server-side decryption), the firewall acts as a reverse proxy, terminating the client's SSL connection and re-encrypting to the server. When client certificates are required for mutual TLS (mTLS), decrypting the traffic would break the authentication handshake because the firewall cannot present the client's certificate to the server; thus, a 'No Decrypt' rule is essential to preserve the end-to-end TLS session and client certificate exchange.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
