- A
Create a decryption policy and use the 'exclude cache' option for financial sites.
Why wrong: The 'exclude cache' option is not related to bypassing decryption.
- B
Create a security policy that allows financial sites without decryption; then create a decryption policy with action 'no-decrypt' for those sites.
Why wrong: Security policies do not control decryption actions.
- C
Create a decryption policy with action 'decrypt' and a source zone of internal; then create a decryption exemption for financial URLs.
Why wrong: Decryption exemption is for certificate authentication, not for bypassing decryption.
- D
Create a decryption policy with action 'no-decrypt' for traffic to financial sites, and a catch-all decryption policy with action 'decrypt' for all other traffic.
This ensures financial traffic is not decrypted while all other traffic is decrypted.
PCNSA Decryption and Monitoring Practice Question
This PCNSA practice question tests your understanding of decryption and monitoring. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 company wants to decrypt all SSL/TLS traffic from internal users except traffic to financial sites. The firewall is placed as a forward proxy. Which policy configuration ensures that traffic to financial sites is not decrypted?
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
Create a decryption policy with action 'no-decrypt' for traffic to financial sites, and a catch-all decryption policy with action 'decrypt' for all other traffic.
Option D is correct because it uses a specific 'no-decrypt' action in a decryption policy for financial sites, which explicitly excludes them from SSL/TLS decryption. A catch-all policy with 'decrypt' then ensures all other internal user traffic is decrypted. This approach directly aligns with the forward proxy requirement to decrypt all traffic except the specified financial sites.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Create a decryption policy and use the 'exclude cache' option for financial sites.
Why it's wrong here
The 'exclude cache' option is not related to bypassing decryption.
- ✗

Why this is correct
This ensures financial traffic is not decrypted while all other traffic is decrypted.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse security policies with decryption policies, or mistakenly think that a 'decrypt' action with an exemption list is equivalent to a 'no-decrypt' policy, when in fact Palo Alto Networks requires a separate decryption policy with the 'no-decrypt' action for explicit exclusion.
Detailed technical explanation
How to think about this question
In Palo Alto Networks firewalls, decryption policies are evaluated in order, and the first matching policy determines the action. The 'no-decrypt' action explicitly bypasses SSL/TLS decryption for matching traffic, while a catch-all 'decrypt' policy ensures all other traffic is decrypted. This is critical for forward proxy deployments where the firewall acts as a man-in-the-middle, requiring careful policy ordering to avoid unintended decryption of sensitive traffic like financial sites, which may violate compliance or cause certificate errors.
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 practitioner preparing for the PCNSA exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
