Palo Alto Networks NetSec-Analyst Practice Test 21
Question 200
A controlled network security change requires exactly THREE documented actions. A warehouse analyst receives Device Security policy suggestions for low-confidence industrial sensors and wants to enforce them without validation. Which THREE elements are the necessary diagnosis, correction and proof of success? Select THREE answers.
- Diagnose: Check classification confidence, representative communications and proposed policy destinations and actions.
- Alternative diagnostic: Review device classification confidence, observed destinations, rule hits and device-security telemetry.
- Alternative verification: Cameras continue streaming to their approved NVR while anomalous internet destinations are denied and logged.
- Competing correction: Combine device-aware policy with permitted broker destinations and investigate the unexpected SMB sessions using device and threat evidence.
- Prove: Approved sensor services remain reachable and the deployed policy matches only confirmed device functions.
- Correct: Validate device classification and observed behaviors before accepting high-confidence policy recommendations for the correct sensor profile.
Explanation
Correct Answer
A:Success is demonstrated when: Approved sensor services remain reachable and the deployed policy matches only confirmed device functions. These checks distinguish the actual cause before changes are attempted.
E:Automatically generated IoT policy recommendations depend on reliable device identity and representative traffic history. This is the observable acceptance result for the exact reported problem.
F:The expected outcome is: Approved sensor services remain reachable and the deployed policy matches only confirmed device functions. Automatically generated IoT policy recommendations depend on reliable device identity and representative traffic history.
Incorrect Answers
B:This corresponds to a different condition: A hospital's smart infusion pumps should communicate only with a device management service, but they contact unknown internet hosts. The directly relevant correction here is: Validate device classification and observed behaviors before accepting high-confidence policy recommendations for the correct sensor profile.
C:This corresponds to a different condition: An office's IP cameras begin sending outbound DNS and HTTP traffic to unfamiliar countries outside their normal NVR workflow. The current report has a distinct control gap; Automatically generated IoT policy recommendations depend on reliable device identity and representative traffic history.
D:This corresponds to a different condition: A manufacturing plant's OT temperature probes need to reach one telemetry broker, but unexpected SMB scanning is observed from one probe. The directly relevant correction here is: Validate device classification and observed behaviors before accepting high-confidence policy recommendations for the correct sensor profile.

Question 205
A manufacturing plant's OT temperature probes need to reach one telemetry broker, but unexpected SMB scanning is observed from one probe. The team is considering the shortcut: Create a zone-wide SMB allow rule because one sensor's management tool uses TCP networking. Which policy or object change DIRECTLY addresses the case?

Explanation
Correct Answer
C:The expected outcome is: The probes continue approved telemetry while SMB scans are denied and visible to the incident team. This correction targets the observed gap rather than a neighboring symptom.
Incorrect Answers
A:This corresponds to a different condition: A hospital's smart infusion pumps should communicate only with a device management service, but they contact unknown internet hosts. The current report has a distinct control gap; Purpose-built IoT and OT endpoints should not inherit lateral access to unrelated enterprise services.
B:This corresponds to a different condition: An office's IP cameras begin sending outbound DNS and HTTP traffic to unfamiliar countries outside their normal NVR workflow. The current report has a distinct control gap; Purpose-built IoT and OT endpoints should not inherit lateral access to unrelated enterprise services.
D:That option would create a zone-wide SMB allow rule because one sensor's management tool uses TCP networking, but it addresses a different concern. This correction targets the observed gap rather than a neighboring symptom.
Question 206
In a Palo Alto Networks configuration review, the following condition is reported: A manufacturing plant's OT temperature probes need to reach one telemetry broker, but unexpected SMB scanning is observed from one probe. The proposed correction is to combine device-aware policy with permitted broker destinations and investigate the unexpected SMB sessions using device and threat evidence. Which technical principle BEST explains why this correction is appropriate? Select ONE best answer.
- Device profiles and observed communication baselines help separate permitted camera operations from anomalous sessions.
- Purpose-built IoT and OT endpoints should not inherit lateral access to unrelated enterprise services.
- IoT profile enforcement should reflect task-specific communications rather than general workforce privileges.
- Device-aware segmentation reduces exposure for specialized IoT assets without granting broad internet access.
