Quick Answer
The answer is App-ID and Content-ID. These two features work together to enforce approved applications on a network: App-ID identifies and controls the application itself, while Content-ID controls the specific file transfers and data patterns within that application, such as blocking file uploads or scanning for sensitive data patterns. On the Palo Alto Networks PCNSA exam, this question tests your understanding of how the single-pass architecture combines these technologies—a common trap is confusing Content-ID with URL filtering or User-ID, which manage web categories and user access respectively, not application-level content control. To remember, think of App-ID as the gatekeeper for which apps are allowed, and Content-ID as the inspector that checks what passes through that gate. A useful memory tip: “App decides the party, Content checks the gifts.”
This PCNSA practice question tests your understanding of securing traffic. 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.
An administrator wants to enforce that only certain approved applications can be used on the network. Which TWO features should be configured?
WildFire
Why wrong: WildFire is for malware analysis, not application control.
User-ID
Why wrong: User-ID identifies users, not applications.
Application-ID
Allows identification and enforcement based on application signatures.
URL Filtering
Why wrong: URL filtering controls web categories, not application usage.
Content-ID
Content-ID controls file types and data patterns within applications.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Application-ID
Options A and C are correct. Application-ID identifies and controls applications, while Content-ID controls file transfers and data patterns. User-ID controls user access, URL filtering controls web categories, WildFire analyzes unknown files.
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
For each option: why learners choose it and why it is or isn't the right answer here.
WildFire
Why it's wrong here
WildFire is for malware analysis, not application control.
User-ID
Why it's wrong here
User-ID identifies users, not applications.
Application-ID
Why this is correct
Allows identification and enforcement based on application signatures.
Related concept
Static NAT maps one inside address to one outside address.
URL Filtering
Why it's wrong here
URL filtering controls web categories, not application usage.
Content-ID
Why this is correct
Content-ID controls file types and data patterns within applications.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
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
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.
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
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
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 PCNSA NAT questions on configuration and troubleshooting.
