- A
Disable App-ID on port 8443.
Why wrong: Disabling App-ID prevents identification.
- B
Use an application override with port 8443.
Why wrong: Override bypasses App-ID.
- C
Add a custom URL category for the domain.
Why wrong: URL categories do not influence App-ID.
- D
Create a custom application with a hostname condition.
Hostname condition matches the SNI to identify the application.
- E
Enable SSL forward proxy and import the internal CA certificate.
Decryption is needed to access SNI for hostname-based identification.
Question 198 of 516
Improving Custom Application Identification for SSL/TLS Traffic
This PCNSE practice question tests your understanding of securing traffic and app-id. 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.
Which TWO actions can help App-ID correctly identify a custom application that communicates over TCP port 8443 using SSL/TLS with a known internal hostname?
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 custom application with a hostname condition.
Option D is correct because a custom application can be defined with a hostname condition to match traffic based on the SNI field in the TLS handshake, which allows App-ID to identify the application even when it uses a non-standard port like 8443. Option E is correct because enabling SSL forward proxy with the internal CA certificate allows the firewall to decrypt the SSL/TLS traffic and inspect the application payload, which is necessary for App-ID to accurately identify the custom application.
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
The trap here is that candidates often confuse application override with custom application creation, thinking that an override helps identify the application, when in fact it bypasses App-ID entirely and only assigns a static label.
Detailed technical explanation
How to think about this question
App-ID uses multiple mechanisms to identify applications, including protocol decoders, signatures, and hostname-based conditions. For SSL/TLS traffic, the firewall can inspect the Server Name Indication (SNI) field in the ClientHello message to match against a hostname condition in a custom application, even without decryption. However, if the traffic is encrypted and the SNI is not sufficient, SSL forward proxy decryption is required to inspect the application layer payload, which is why importing the internal CA certificate is necessary for the firewall to act as a trusted intermediary.
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.

Same concept, more angles
1 more ways this is tested on PCNSE
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. An organization uses a SaaS application that runs on a dynamic set of IP addresses. The application traffic is currently identified as ssl and not as the specific application. How can the administrator improve application identification for this SaaS application?
medium- A.Disable App-ID for that traffic to reduce overhead.
- ✓ B.Create a custom application with hostname conditions.
- C.Use a port-based application override.
- D.Configure a URL filtering category for the application.
Why B: Option B is correct because App-ID can identify SaaS applications by hostname conditions when the application uses a dynamic set of IP addresses. By creating a custom application with hostname conditions (e.g., matching the FQDN of the SaaS service), the firewall can accurately identify the traffic as that specific application rather than generic SSL, even as the backend IPs change. This leverages the firewall's ability to inspect the Server Name Indication (SNI) field in the TLS handshake or the HTTP Host header.
