Palo Alto Networks NetSec-Analyst Practice Test 20
Question 190
A network security analyst needs exactly TWO case-specific control steps. An office's IP cameras begin sending outbound DNS and HTTP traffic to unfamiliar countries outside their normal NVR workflow. Which TWO actions directly belong to the safe diagnostic and remediation workflow? Select TWO answers.
- Collect evidence: Inspect identified camera profile, permitted NVR endpoints and current DNS/HTTP traffic by device identity.
- Apply correction: Correlate IoT profile behavior with threat and traffic logs and enforce an appropriate camera-destination policy exception or block.
- Alternative verification: Printers receive authorized jobs and updates while off-baseline connections are denied or investigated.
- Competing correction: Validate device classification and observed behaviors before accepting high-confidence policy recommendations for the correct sensor profile.
- Alternative diagnostic: Inspect device type confidence, broker connection logs, unexpected SMB traffic and matching rules.
Explanation
Correct Answer
A:Success is demonstrated when: Cameras continue streaming to their approved NVR while anomalous internet destinations are denied and logged. Device profiles and observed communication baselines help separate permitted camera operations from anomalous sessions.
B:The expected outcome is: Cameras continue streaming to their approved NVR while anomalous internet destinations are denied and logged. Device profiles and observed communication baselines help separate permitted camera operations from anomalous sessions.
Incorrect Answers
C:This corresponds to a different condition: A print services team treats every printer as a general-purpose laptop and applies a broad user internet policy, exposing the embedded devices. Alternative verification: Printers receive authorized jobs and updates while off-baseline connections are denied or investigated.
D:This corresponds to a different condition: A warehouse analyst receives Device Security policy suggestions for low-confidence industrial sensors and wants to enforce them without validation. Competing correction: Validate device classification and observed behaviors before accepting high-confidence policy recommendations for the correct sensor profile.
E: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 discriminating evidence is: Inspect identified camera profile, permitted NVR endpoints and current DNS/HTTP traffic by device identity.
Question 191
A supervisor is assessing the risks of a rushed remediation. An office's IP cameras begin sending outbound DNS and HTTP traffic to unfamiliar countries outside their normal NVR workflow. Which proposed shortcut should the analyst REJECT as unsafe or ineffective? Select ONE best answer.
- Disable the entire camera VLAN to avoid investigating which endpoints are compromised.
- Correlate IoT profile behavior with threat and traffic logs and enforce an appropriate camera-destination policy exception or block.
- Inspect identified camera profile, permitted NVR endpoints and current DNS/HTTP traffic by device identity.
- Cameras continue streaming to their approved NVR while anomalous internet destinations are denied and logged.
Explanation
Correct Answer
A:This is the unsafe proposal in the stated scenario because it bypasses the control boundary. The required principle is: Device profiles and observed communication baselines help separate permitted camera operations from anomalous sessions.
Incorrect Answers
B:This is a controlled and useful step for the described condition, not the unsafe shortcut. The shortcut to reject is: Disable the entire camera VLAN to avoid investigating which endpoints are compromised.
C:This is a controlled and useful step for the described condition, not the unsafe shortcut. Device profiles and observed communication baselines help separate permitted camera operations from anomalous sessions.
D:This is a controlled and useful step for the described condition, not the unsafe shortcut. Cameras continue streaming to their approved NVR while anomalous internet destinations are denied and logged.
Question 192
A branch operations team must document a cause-based remediation with a measurable outcome. An office's IP cameras begin sending outbound DNS and HTTP traffic to unfamiliar countries outside their normal NVR workflow. What is the BEST complete investigation–change–verification plan? Select ONE best answer.
- Investigate: Verify identified printer identities, destination traffic baseline and matches against the scoped IoT policy. Correct: Assign a high-confidence IoT printer profile and a minimum-required destination rule for print and management services. Verify: Printers receive authorized jobs and updates while off-baseline connections are denied or investigated.
- Investigate: Inspect device type confidence, broker connection logs, unexpected SMB traffic and matching rules. Correct: Combine device-aware policy with permitted broker destinations and investigate the unexpected SMB sessions using device and threat evidence. Verify: The probes continue approved telemetry while SMB scans are denied and visible to the incident team.
- Investigate: Inspect identified camera profile, permitted NVR endpoints and current DNS/HTTP traffic by device identity. Correct: Correlate IoT profile behavior with threat and traffic logs and enforce an appropriate camera-destination policy exception or block. Verify: Cameras continue streaming to their approved NVR while anomalous internet destinations are denied and logged.
- Investigate: Check classification confidence, representative communications and proposed policy destinations and actions. Correct: Validate device classification and observed behaviors before accepting high-confidence policy recommendations for the correct sensor profile. Verify: Approved sensor services remain reachable and the deployed policy matches only confirmed device functions.
