- A
Create an application override for the custom application.
An application override forces the firewall to classify the traffic as the specified application, ensuring correct identification.
- B
Enable SSL decryption on the traffic.
Why wrong: The traffic is HTTP, not HTTPS, so SSL decryption is not relevant.
- C
Set the application to 'any' in the security policy.
Why wrong: Setting application to any bypasses application matching, but does not help identify the custom application.
- D
Configure a security policy rule to allow the application.
Why wrong: A security rule allows or blocks traffic but does not affect identification.
- E
Create a custom App-ID signature for the application.
A custom signature enables App-ID to detect the application based on traffic patterns.
PCNSE Securing Traffic and App-ID Practice Question
This PCNSE practice question tests your understanding of securing traffic and app-id. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
A security administrator is configuring App-ID to identify custom applications over TCP port 8080. The traffic is HTTP-based but the firewall is classifying it as 'web-browsing'. Which two steps should the administrator take to ensure the traffic is correctly identified as the custom application? (Choose two.)
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 an application override for the custom application.
Option A (create an application override) forces the firewall to classify the traffic as the custom application regardless of detection. Option B (create a custom App-ID signature) allows the firewall to properly identify the application via pattern matching. Option C is about allowing, not identifying. Option D is irrelevant for HTTP traffic. Option E sets application to any, which prevents identification.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create an application override for the custom application.
- ✗
Enable SSL decryption on the traffic.
- ✗
Set the application to 'any' in the security policy.
Why it's wrong here
Setting application to any bypasses application matching, but does not help identify the custom application.
- ✗
Configure a security policy rule to allow the application.
Why it's wrong here
A security rule allows or blocks traffic but does not affect identification.
- ✓
Create a custom App-ID signature for the application.
Why this is correct
A custom signature enables App-ID to detect the application based on traffic patterns.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PCNSE NAT questions on configuration and troubleshooting.
