- A
Use an internal certificate authority (CA) and distribute the CA certificate to all clients via Group Policy.
Standard best practice for enterprise environments.
- B
Use a self-signed certificate and manually install it on each client.
Why wrong: Not scalable for large enterprises.
- C
Use a wildcard certificate from a public CA to simplify deployment.
Why wrong: Wildcard certificates are not recommended for decryption due to security concerns.
- D
Use a certificate from a public CA that is already trusted by clients.
Why wrong: Firewall would need the private key, which is usually not available for public CAs.
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.
Which best practice should be followed for certificate management when deploying SSL Forward Proxy decryption in a large enterprise?

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
Use an internal certificate authority (CA) and distribute the CA certificate to all clients via Group Policy.
Using an internal CA and distributing its certificate via Group Policy ensures that all clients trust the decryption certificate used by the firewall to re-encrypt traffic. This avoids certificate warnings and allows seamless SSL Forward Proxy decryption. It also enables centralized management and revocation, which is critical for large enterprise deployments.
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
Palo Alto Networks often tests the misconception that a public CA certificate can be used directly for re-encryption, but the trap here is that the firewall must generate certificates on-the-fly, requiring an internal CA to sign them, not a public CA certificate that would expose the private key.
Detailed technical explanation
How to think about this question
In SSL Forward Proxy decryption, the firewall acts as a man-in-the-middle, terminating the client's SSL connection and initiating a new SSL connection to the server. For the client to trust the firewall's re-encrypted certificate, the firewall must present a certificate signed by a CA that the client trusts. Using an internal CA allows the firewall to dynamically generate and sign certificates for each destination, enabling granular policy control and certificate pinning bypass. The CA certificate is distributed via Group Policy to ensure all domain-joined clients trust it, avoiding 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 PCNSE 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.
