Question 720

A network security analyst needs exactly TWO case-specific control steps. A SOC alert recommends changing service any to application-default, but some sessions use an approved nonstandard port. Which TWO actions directly belong to the safe diagnostic and remediation workflow? Select TWO answers.

  1. Competing correction: Use Activity Insights and Log Viewer to correlate observed application activity with users and network sources.
  2. Collect evidence: Inspect traffic log service ports, app identity, current rule and proposed optimizer change.
  3. Alternative verification: The team produces a short evidence-backed list of affected branches and specific follow-up actions.
  4. Apply correction: Validate each observed application/port pattern and use narrowly scoped explicit services where application-default would disrupt an approved custom deployment.
  5. Alternative diagnostic: Inspect observed App-IDs, dependencies, suggested service scope and recent rule hit data.

Explanation

Correct Answer

B:

Application-default reduces unnecessary ports only when observed service use aligns to the application's documented defaults. If confirmed, the narrowly scoped remedy is: Validate each observed application/port pattern and use narrowly scoped explicit services where application-default would disrupt an approved custom deployment.

D:

Application-default reduces unnecessary ports only when observed service use aligns to the application's documented defaults. The expected outcome is: Normal apps use application-default while the documented custom-port service receives its own narrow exception.

Incorrect Answers

A:

This corresponds to a different condition: An analyst sees a surge in unapproved collaboration applications and wants to determine which user groups and destinations drive it. Competing correction: Use Activity Insights and Log Viewer to correlate observed application activity with users and network sources.

C:

This corresponds to a different condition: A security manager wants a high-level view of deteriorating firewall posture across branches before choosing where to investigate. Alternative verification: The team produces a short evidence-backed list of affected branches and specific follow-up actions.

E:

This corresponds to a different condition: A legacy allow rule uses service any and application any, and security leadership wants a safer application-specific replacement. Alternative diagnostic: Inspect observed App-IDs, dependencies, suggested service scope and recent rule hit data.

Question 721

An intrusion alert appears for a specific branch, but a junior analyst searches all tenant logs and cannot isolate the relevant sessions. The team is considering the shortcut: Treat the first globally matching threat log entry as the incident without checking its device. Which policy or object change DIRECTLY addresses the case? Select ONE best answer.

  1. Use incident context and correlated alerts, then pivot to Log Viewer for supporting traffic and threat evidence.
  2. Pivot to applicable DLP or data-filtering incidents with user, filename, pattern and action details as permitted.
  3. Filter Log Viewer by device, time interval, log type and session identifiers, then correlate Threat and Traffic records.
  4. Treat the first globally matching threat log entry as the incident without checking its device.

Explanation

Correct Answer

C:

Confirm its effect by checking: Review threat ID, source/destination, device, session identifiers and selected time zone.

Incorrect Answers

A:

This corresponds to a different condition: A multi-site incident appears in SCM Incidents and Alerts and the responder wants to distinguish duplicate notifications from one underlying cause. The directly relevant correction here is: Filter Log Viewer by device, time interval, log type and session identifiers, then correlate Threat and Traffic records.

B:

This corresponds to a different condition: A data-protection alert suggests a sensitive file upload but the analyst sees no DLP evidence in a generic Traffic log search. The directly relevant correction here is: Filter Log Viewer by device, time interval, log type and session identifiers, then correlate Threat and Traffic records.

D:

Treat the first globally matching threat log entry as the incident without checking its device. This is the shortcut under scrutiny. In this case it fails because: Precise filters allow incident evidence to be linked to affected flows and enforcement rules. A safe correction instead is: Filter Log Viewer by device, time interval, log type and session identifiers, then correlate Threat and Traffic records. Verify using: Review threat ID, source/destination, device, session identifiers and selected time zone.

Question 722

In a Palo Alto Networks configuration review, the following condition is reported: An intrusion alert appears for a specific branch, but a junior analyst searches all tenant logs and cannot isolate the relevant sessions. The proposed correction is to filter Log Viewer by device, time interval, log type and session identifiers, then correlate Threat and Traffic records. Which technical principle BEST explains why this correction is appropriate? Select ONE best answer.

  1. Artifact verdicts and network sessions are separate evidence types that must be correlated for reliable incident analysis.
  2. DLP incident records provide content-match context that ordinary session logs may omit.
  3. An incident's grouped context and raw logs support a more accurate response than counting notification cards.
  4. Precise filters allow incident evidence to be linked to affected flows and enforcement rules.

Explanation

Correct Answer

D:

The validation result should be: The identified branch's suspect sessions are found and unrelated device traffic is excluded from the case.

Incorrect Answers

A:

This corresponds to a different condition: A newly detected malware file is submitted for analysis and an analyst needs to link the verdict back to a blocked application session. The directly relevant correction here is: Filter Log Viewer by device, time interval, log type and session identifiers, then correlate Threat and Traffic records.

B:

This corresponds to a different condition: A data-protection alert suggests a sensitive file upload but the analyst sees no DLP evidence in a generic Traffic log search. The current report has a distinct control gap; Precise filters allow incident evidence to be linked to affected flows and enforcement rules.

C:

This corresponds to a different condition: A multi-site incident appears in SCM Incidents and Alerts and the responder wants to distinguish duplicate notifications from one underlying cause. The current report has a distinct control gap; Precise filters allow incident evidence to be linked to affected flows and enforcement rules.

Question 723

An analyst must collect precise technical evidence before changing configuration. An intrusion alert appears for a specific branch, but a junior analyst searches all tenant logs and cannot isolate the relevant sessions. Which investigation would BEST isolate this specific mismatch? Select ONE best answer.

  1. Inspect file hash, verdict, source endpoint, submission time and matching network event details.
  2. Review threat ID, source/destination, device, session identifiers and selected time zone.
  3. Review DLP profile match, log category, source user, destination and configured enforcement action.
  4. Examine incident timeline, affected assets and correlated events before selecting remediation.

Explanation

Correct Answer

B:

If confirmed, the narrowly scoped remedy is: Filter Log Viewer by device, time interval, log type and session identifiers, then correlate Threat and Traffic records.

Incorrect Answers

A:

This corresponds to a different condition: A newly detected malware file is submitted for analysis and an analyst needs to link the verdict back to a blocked application session. The current report has a distinct control gap; Precise filters allow incident evidence to be linked to affected flows and enforcement rules.

C:

This corresponds to a different condition: A data-protection alert suggests a sensitive file upload but the analyst sees no DLP evidence in a generic Traffic log search. The discriminating evidence is: Review threat ID, source/destination, device, session identifiers and selected time zone.

D:

This corresponds to a different condition: A multi-site incident appears in SCM Incidents and Alerts and the responder wants to distinguish duplicate notifications from one underlying cause. The discriminating evidence is: Review threat ID, source/destination, device, session identifiers and selected time zone.

Question 724

The approved controlled change was applied to this situation: An intrusion alert appears for a specific branch, but a junior analyst searches all tenant logs and cannot isolate the relevant sessions. The change was to filter Log Viewer by device, time interval, log type and session identifiers, then correlate Threat and Traffic records. Which verification result most directly demonstrates success? Select ONE best answer.

  1. The identified branch's suspect sessions are found and unrelated device traffic is excluded from the case.
  2. The synthetic test upload generates the expected sensitive-data incident with correct contextual fields.
  3. A documented single case links all relevant alerts and shows the controlled remediation effect.
  4. The incident record cites the correct sample and affected session, with the enforcement outcome verified.

Explanation

Correct Answer

A:

This is the observable acceptance result for the exact reported problem. Precise filters allow incident evidence to be linked to affected flows and enforcement rules.

Incorrect Answers

B:

This corresponds to a different condition: A data-protection alert suggests a sensitive file upload but the analyst sees no DLP evidence in a generic Traffic log search. The synthetic test upload generates the expected sensitive-data incident with correct contextual fields.

C:

This corresponds to a different condition: A multi-site incident appears in SCM Incidents and Alerts and the responder wants to distinguish duplicate notifications from one underlying cause. A documented single case links all relevant alerts and shows the controlled remediation effect.

D:

This corresponds to a different condition: A newly detected malware file is submitted for analysis and an analyst needs to link the verdict back to a blocked application session. The discriminating evidence is: Review threat ID, source/destination, device, session identifiers and selected time zone.

Question 725

A supervisor is assessing the risks of a rushed remediation. An intrusion alert appears for a specific branch, but a junior analyst searches all tenant logs and cannot isolate the relevant sessions. Which proposed shortcut should the analyst REJECT as unsafe or ineffective? Select ONE best answer.

  1. Review threat ID, source/destination, device, session identifiers and selected time zone.
  2. The identified branch's suspect sessions are found and unrelated device traffic is excluded from the case.
  3. Filter Log Viewer by device, time interval, log type and session identifiers, then correlate Threat and Traffic records.
  4. Treat the first globally matching threat log entry as the incident without checking its device.

Explanation

Correct Answer

D:

This is the unsafe proposal in the stated scenario because it bypasses the control boundary. The appropriate controlled change is: Filter Log Viewer by device, time interval, log type and session identifiers, then correlate Threat and Traffic records.

Incorrect Answers

A:

This is a controlled and useful step for the described condition, not the unsafe shortcut. The shortcut to reject is: Treat the first globally matching threat log entry as the incident without checking its device.

B:

This is a controlled and useful step for the described condition, not the unsafe shortcut. Precise filters allow incident evidence to be linked to affected flows and enforcement rules.

C:

This is a controlled and useful step for the described condition, not the unsafe shortcut. Filter Log Viewer by device, time interval, log type and session identifiers, then correlate Threat and Traffic records.
