PCNSE Decryption and SSL Inspection Practice Question
This PCNSE practice question tests your understanding of decryption and ssl inspection. 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.
Exhibit
Refer to the exhibit.
```
Decryption Policy Rule 1:
Name: Decrypt_HR_Traffic
Source: 10.0.1.0/24
Destination: any
Service: any
URL Category: Human-Resources
Action: decrypt
Decryption Policy Rule 2:
Name: Decrypt_All
Source: any
Destination: any
Service: any
URL Category: any
Action: decrypt
Decryption Policy Rule 3:
Name: No_Decrypt_Finance
Source: any
Destination: any
Service: any
URL Category: Finance
Action: no-decrypt
Ordering: Rule 1, Rule 2, Rule 3
```
A user from subnet 10.0.1.0/24 accesses a website categorized as 'Finance'. Based on the exhibit, what will be the result?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The traffic will be decrypted by Rule 2.
Option B is correct because Rule 2 matches traffic from subnet 10.0.1.0/24 to the 'Finance' category and has an action of 'decrypt'. The exhibit shows Rule 2 with source 10.0.1.0/24, destination category 'Finance', and action 'decrypt'. Since the user's traffic matches all criteria in Rule 2, it will be decrypted. Rule 3 is not evaluated because Rule 2 matches first and has a higher priority (lower rule number).
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The traffic will not be decrypted because Rule 3 matches.
Why it's wrong here
Rule 3 is after Rule 2, so Rule 2 applies first.
✓
The traffic will be decrypted by Rule 2.
Why this is correct
Rule 2 is a catch-all that will match and decrypt.
Related concept
Read the scenario before looking for a memorised answer.
✗
The traffic will be blocked because no matching rule exists.
Why it's wrong here
A decryption policy does not block; it only decides to decrypt or not.
✗
The traffic will be decrypted by Rule 1.
Why it's wrong here
Rule 1 only matches HR category, not Finance.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Palo Alto Networks often tests the rule evaluation order in decryption policies, where candidates mistakenly think a later rule (like Rule 3) overrides an earlier matching rule (Rule 2) due to a more specific category or action, but in reality, the first match wins regardless of specificity.
Detailed technical explanation
How to think about this question
In Palo Alto Networks decryption policies, rules are evaluated in order from top to bottom (lowest rule number first). The first matching rule determines the action, and subsequent rules are ignored. The 'no-decrypt' action in Rule 1 explicitly bypasses decryption for that source, but it does not apply here because the source is 10.0.1.0/24. Decryption policies can also include SSL Forward Proxy or SSH Proxy settings, and the 'decrypt' action typically involves re-signing the server certificate with a trusted CA certificate installed on clients.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
