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.

Exhibit

Refer to the exhibit.

{
  "decryption_rules": [
    {
      "name": "rule1",
      "source_zone": ["trust"],
      "destination_zone": ["untrust"],
      "source_address": ["any"],
      "destination_address": ["any"],
      "category": ["financial-services"],
      "action": "no-decrypt",
      "description": "Skip decryption for finance sites"
    },

      "action": "decrypt",
      "description": "Decrypt all other traffic"
    }
  ]
}

Refer to the exhibit. A user in the trust zone accesses a banking site (category: financial-services). What action will the firewall take on this HTTPS session?

A
Error due to rule conflict
Why wrong: No conflict; first match applies.
B
Block
Why wrong: No block action in decryption rules.
C
No Decrypt (bypass decryption)
Rule1 matches financial-services and action is no-decrypt.
D
Decrypt
Why wrong: Rule2 would decrypt if rule1 did not match, but rule1 matches.

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

✓

No Decrypt (bypass decryption)

The firewall is configured with a decryption policy that matches the banking site (financial-services category) and has the action set to 'No Decrypt'. This action explicitly bypasses SSL/TLS decryption for the session, allowing the HTTPS traffic to pass through without inspection. The user in the trust zone accessing the site will therefore have the session proceed without decryption.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Rule2 would decrypt if rule1 did not match, but rule1 matches.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often assume any HTTPS session must be decrypted for inspection, but the 'No Decrypt' action explicitly bypasses decryption while still allowing the session through, which is a common configuration for regulated or sensitive traffic categories.

Detailed technical explanation

How to think about this question

In Palo Alto Networks firewalls, decryption policies are evaluated before security policies, and the 'No Decrypt' action instructs the firewall to forward the HTTPS session without intercepting or re-encrypting the traffic. This is commonly used for sensitive categories like financial services to avoid breaking certificate pinning or violating compliance requirements. The firewall still applies security policy rules to the session, but without decrypting the payload, it can only inspect metadata such as SNI and IP addresses.

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.
