Palo Alto Networks NetSec-Analyst Practice Test 77
Question 760
A network security analyst needs exactly TWO case-specific control steps. An analyst investigates a data exfiltration alert but log-view filters mistakenly use local time for events stored in UTC, hiding the relevant window. Which TWO actions directly belong to the safe diagnostic and remediation workflow? Select TWO answers.
- Apply correction: Normalize the incident's timestamps and expand the Log Viewer query to the correct event time zone and device context.
- Alternative diagnostic: Review threat ID, source/destination, device, session identifiers and selected time zone.
- Alternative verification: The responder isolates the current cause and documents how new logs changed after remediation.
- Collect evidence: Compare alert time zone, source event timestamp, query interval and other correlated telemetry.
- Competing correction: Update the supported incident/alert routing and enrichment context and validate correlations in Log Viewer.
Explanation
Correct Answer
A:The expected outcome is: The relevant log records appear and their sequence aligns with the incident timeline. Incorrect time conversion can hide existing evidence even when logging and retention are healthy.
D:Success is demonstrated when: The relevant log records appear and their sequence aligns with the incident timeline. Incorrect time conversion can hide existing evidence even when logging and retention are healthy.
Incorrect Answers
B:This corresponds to a different condition: An intrusion alert appears for a specific branch, but a junior analyst searches all tenant logs and cannot isolate the relevant sessions. The discriminating evidence is: Compare alert time zone, source event timestamp, query interval and other correlated telemetry.
C:This corresponds to a different condition: A production firewall has a suspected forwarding problem but incident monitoring shows only old alerts unrelated to the current outage. Alternative verification: The responder isolates the current cause and documents how new logs changed after remediation.
E:This corresponds to a different condition: A newly created incident rule notifies the SOC but does not include the affected policy target or asset information in the case. Competing correction: Update the supported incident/alert routing and enrichment context and validate correlations in Log Viewer.
Question 761
A supervisor is assessing the risks of a rushed remediation. An analyst investigates a data exfiltration alert but log-view filters mistakenly use local time for events stored in UTC, hiding the relevant window. Which proposed shortcut should the analyst REJECT as unsafe or ineffective? Select ONE best answer.
- Normalize the incident's timestamps and expand the Log Viewer query to the correct event time zone and device context.
- Compare alert time zone, source event timestamp, query interval and other correlated telemetry.
- The relevant log records appear and their sequence aligns with the incident timeline.
- Assume no logs were generated because a misaligned fifteen-minute query returned zero rows.
Explanation
Correct Answer
D:This is the unsafe proposal in the stated scenario because it bypasses the control boundary. The required principle is: Incorrect time conversion can hide existing evidence even when logging and retention are healthy.
Incorrect Answers
A:This is a controlled and useful step for the described condition, not the unsafe shortcut. The shortcut to reject is: Assume no logs were generated because a misaligned fifteen-minute query returned zero rows.
B:This is a controlled and useful step for the described condition, not the unsafe shortcut. Incorrect time conversion can hide existing evidence even when logging and retention are healthy.
C:This is a controlled and useful step for the described condition, not the unsafe shortcut. The relevant log records appear and their sequence aligns with the incident timeline.
Question 762
A branch operations team must document a cause-based remediation with a measurable outcome. An analyst investigates a data exfiltration alert but log-view filters mistakenly use local time for events stored in UTC, hiding the relevant window. What is the BEST complete investigation–change–verification plan? Select ONE best answer.
- Investigate: Review threat ID, source/destination, device, session identifiers and selected time zone. Correct: Filter Log Viewer by device, time interval, log type and session identifiers, then correlate Threat and Traffic records. Verify: The identified branch's suspect sessions are found and unrelated device traffic is excluded from the case.
- Investigate: Inspect log timestamps, device association, session actions and the latest health events. Correct: Use current Log Viewer data, relevant device health records and Incidents timelines rather than relying on historical alert counts. Verify: The responder isolates the current cause and documents how new logs changed after remediation.
- Investigate: Compare alert time zone, source event timestamp, query interval and other correlated telemetry. Correct: Normalize the incident's timestamps and expand the Log Viewer query to the correct event time zone and device context. Verify: The relevant log records appear and their sequence aligns with the incident timeline.
- Investigate: Examine the originating log fields, incident grouping and notification payload for missing context. Correct: Update the supported incident/alert routing and enrichment context and validate correlations in Log Viewer. Verify: A controlled test alert contains the correct asset, matched policy and links to supporting logs.
Explanation
Correct Answer
C:It avoids the unsupported shortcut: Assume no logs were generated because a misaligned fifteen-minute query returned zero rows.
Incorrect Answers
A:Review threat ID, source/destination, device, session identifiers and selected time zone. Correct: Filter Log Viewer by device, time interval, log type and session identifiers, then correlate Threat and Traffic records. Verify: The identified branch's suspect sessions are found and unrelated device traffic is excluded from the case. This corresponds to a different condition: An intrusion alert appears for a specific branch, but a junior analyst searches all tenant logs and cannot isolate the relevant sessions. The current report has a distinct control gap; Incorrect time conversion can hide existing evidence even when logging and retention are healthy. The directly relevant correction here is: Normalize the incident's timestamps and expand the Log Viewer query to the correct event time zone and device context. The discriminating evidence is: Compare alert time zone, source event timestamp, query interval and other correlated telemetry.
B:Inspect log timestamps, device association, session actions and the latest health events. Correct: Use current Log Viewer data, relevant device health records and Incidents timelines rather than relying on historical alert counts. Verify: The responder isolates the current cause and documents how new logs changed after remediation. This corresponds to a different condition: A production firewall has a suspected forwarding problem but incident monitoring shows only old alerts unrelated to the current outage. The current report has a distinct control gap; Incorrect time conversion can hide existing evidence even when logging and retention are healthy. The directly relevant correction here is: Normalize the incident's timestamps and expand the Log Viewer query to the correct event time zone and device context. The discriminating evidence is: Compare alert time zone, source event timestamp, query interval and other correlated telemetry.
D:Examine the originating log fields, incident grouping and notification payload for missing context. Correct: Update the supported incident/alert routing and enrichment context and validate correlations in Log Viewer.

Question 763
A production firewall has a suspected forwarding problem but incident monitoring shows only old alerts unrelated to the current outage. The team is considering the shortcut: Restore last year's policy snapshot because an old alert card mentions the same interface. Which policy or object change DIRECTLY addresses the case? Select ONE best answer.
- Filter Log Viewer by device, time interval, log type and session identifiers, then correlate Threat and Traffic records.
- Restore last year's policy snapshot because an old alert card mentions the same interface.
- Update the supported incident/alert routing and enrichment context and validate correlations in Log Viewer.
- Use current Log Viewer data, relevant device health records and Incidents timelines rather than relying on historical alert counts.

A:This corresponds to a different condition: An intrusion alert appears for a specific branch, but a junior analyst searches all tenant logs and cannot isolate the relevant sessions. The directly relevant correction here is: Use current Log Viewer data, relevant device health records and Incidents timelines rather than relying on historical alert counts.
B:Restore last year's policy snapshot because an old alert card mentions the same interface. This is the shortcut under scrutiny. In this case it fails because: Current operational evidence and alert recency matter when diagnosing a live incident. A safe correction instead is: Use current Log Viewer data, relevant device health records and Incidents timelines rather than relying on historical alert counts. Verify using: Inspect log timestamps, device association, session actions and the latest health events.
C:This corresponds to a different condition: A newly created incident rule notifies the SOC but does not include the affected policy target or asset information in the case. The directly relevant correction here is: Use current Log Viewer data, relevant device health records and Incidents timelines rather than relying on historical alert counts.
Question 764
In a Palo Alto Networks configuration review, the following condition is reported: A production firewall has a suspected forwarding problem but incident monitoring shows only old alerts unrelated to the current outage. The proposed correction is to use current Log Viewer data, relevant device health records and Incidents timelines rather than relying on historical alert counts. Which technical principle BEST explains why this correction is appropriate? Select ONE best answer.
- Useful incident handling requires traceable asset, rule, event and severity evidence for remediation.
- An incident's grouped context and raw logs support a more accurate response than counting notification cards.
- Current operational evidence and alert recency matter when diagnosing a live incident.
- Precise filters allow incident evidence to be linked to affected flows and enforcement rules.
Explanation
Correct Answer
C:The validation result should be: The responder isolates the current cause and documents how new logs changed after remediation.
Incorrect Answers
A:This corresponds to a different condition: A newly created incident rule notifies the SOC but does not include the affected policy target or asset information in the case. The current report has a distinct control gap; Current operational evidence and alert recency matter when diagnosing a live incident.
B: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: Use current Log Viewer data, relevant device health records and Incidents timelines rather than relying on historical alert counts.
D:This corresponds to a different condition: An intrusion alert appears for a specific branch, but a junior analyst searches all tenant logs and cannot isolate the relevant sessions. The current report has a distinct control gap; Current operational evidence and alert recency matter when diagnosing a live incident.
