- A
A root CA certificate installed in the trusted root store on client devices.
Clients must trust the CA that signs the decrypted sessions.
- B
The private key of each destination server.
Why wrong: Private keys are not required for forward proxy.
- C
The server certificate for each destination server.
Why wrong: Server certificates are not needed on clients; the firewall creates on-the-fly.
- D
A decryption policy rule that matches the traffic to be decrypted.
The decryption policy defines which traffic to decrypt.
- E
A decryption profile that specifies the forward proxy certificate (CA certificate).
The profile contains the certificate used to generate certs for decrypted sessions.

PCNSA Securing Traffic Practice Question
This PCNSA practice question tests your understanding of securing traffic. 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.

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
✓
A root CA certificate installed in the trusted root store on client devices.
Options A, D, and E are correct. A root CA certificate installed on client devices is required so clients trust the firewall's generated certificates. A decryption policy rule defines which traffic to decrypt. A decryption profile specifies the forward proxy certificate (CA certificate) used by the firewall. Option B is incorrect because the firewall does not need the private key of each destination server; it generates its own certificate for the session. Option C is incorrect because the server certificate is not required on clients for forward proxy decryption.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
