Palo Alto Networks NetSec-Analyst Practice Test 75
Question 740
A network security analyst needs exactly TWO case-specific control steps. A newly detected malware file is submitted for analysis and an analyst needs to link the verdict back to a blocked application session. Which TWO actions directly belong to the safe diagnostic and remediation workflow? Select TWO answers.
- Collect evidence: Inspect file hash, verdict, source endpoint, submission time and matching network event details.
- Alternative verification: The confirmed incident is escalated promptly while duplicate noise is reduced and raw evidence stays searchable.
- Alternative diagnostic: Compare alert time zone, source event timestamp, query interval and other correlated telemetry.
- Apply correction: Correlate WildFire submission/verdict records with threat or traffic events using timestamps and file/session details.
- Competing correction: Pivot from the incident to Traffic and Threat logs, identify the matched rule and destination, then enforce a narrow policy correction.
Explanation
Correct Answer
A:Artifact verdicts and network sessions are separate evidence types that must be correlated for reliable incident analysis. These checks distinguish the actual cause before changes are attempted.
D:Artifact verdicts and network sessions are separate evidence types that must be correlated for reliable incident analysis. Confirm its effect by checking: Inspect file hash, verdict, source endpoint, submission time and matching network event details.
Incorrect Answers
B:This corresponds to a different condition: A firewall produces dozens of low-severity policy-violation alerts each minute, obscuring a confirmed exploitation incident. The directly relevant correction here is: Correlate WildFire submission/verdict records with threat or traffic events using timestamps and file/session details.
C:This corresponds to a different condition: An analyst investigates a data exfiltration alert but log-view filters mistakenly use local time for events stored in UTC, hiding the relevant window. The current report has a distinct control gap; Artifact verdicts and network sessions are separate evidence types that must be correlated for reliable incident analysis.
E:This corresponds to a different condition: A security team receives an alert for outbound contact with a newly malicious destination but cannot identify which allow rule enabled it. The directly relevant correction here is: Correlate WildFire submission/verdict records with threat or traffic events using timestamps and file/session details.
Question 741
An analyst must collect precise technical evidence before changing configuration. A newly detected malware file is submitted for analysis and an analyst needs to link the verdict back to a blocked application session. Which investigation would BEST isolate this specific mismatch? Select ONE best answer.
- Review alert severity, correlation keys, false-positive examples and escalation workflow.
- Inspect file hash, verdict, source endpoint, submission time and matching network event details.
- Compare alert time zone, source event timestamp, query interval and other correlated telemetry.
- Inspect session source/destination, app, threat match and rule name on the same firewall and time window.
Explanation
Correct Answer
B:Artifact verdicts and network sessions are separate evidence types that must be correlated for reliable incident analysis. If confirmed, the narrowly scoped remedy is: Correlate WildFire submission/verdict records with threat or traffic events using timestamps and file/session details.

Question 745
A firewall produces dozens of low-severity policy-violation alerts each minute, obscuring a confirmed exploitation incident. The team is considering the shortcut: Disable all threat notifications and logging because the alert dashboard is crowded. Which policy or object change DIRECTLY addresses the case? Select ONE best answer.
- Normalize the incident's timestamps and expand the Log Viewer query to the correct event time zone and device context.
- Pivot from the incident to Traffic and Threat logs, identify the matched rule and destination, then enforce a narrow policy correction.
- Prioritize the evidence-backed severe incident, then tune alert rules or suppressions narrowly without suppressing required logs.
- Disable all threat notifications and logging because the alert dashboard is crowded.
Explanation
Correct Answer
C:Noise reduction must retain event evidence and make high-impact alerts actionable rather than erase detection coverage. This correction targets the observed gap rather than a neighboring symptom.
Incorrect Answers
A:This corresponds to a different condition: An analyst investigates a data exfiltration alert but log-view filters mistakenly use local time for events stored in UTC, hiding the relevant window. The current report has a distinct control gap; Noise reduction must retain event evidence and make high-impact alerts actionable rather than erase detection coverage.
B:This corresponds to a different condition: A security team receives an alert for outbound contact with a newly malicious destination but cannot identify which allow rule enabled it. The current report has a distinct control gap; Noise reduction must retain event evidence and make high-impact alerts actionable rather than erase detection coverage.
D:Disable all threat notifications and logging because the alert dashboard is crowded. This is the shortcut under scrutiny. In this case it fails because: Noise reduction must retain event evidence and make high-impact alerts actionable rather than erase detection coverage. A safe correction instead is: Prioritize the evidence-backed severe incident, then tune alert rules or suppressions narrowly without suppressing required logs. Verify using: Review alert severity, correlation keys, false-positive examples and escalation workflow.
Question 746
In a Palo Alto Networks configuration review, the following condition is reported: A firewall produces dozens of low-severity policy-violation alerts each minute, obscuring a confirmed exploitation incident. The proposed correction is to prioritize the evidence-backed severe incident, then tune alert rules or suppressions narrowly without suppressing required logs. Which technical principle BEST explains why this correction is appropriate? Select ONE best answer.
- Linking threat evidence to the rule that permitted a flow supports causal remediation and auditability.
- Noise reduction must retain event evidence and make high-impact alerts actionable rather than erase detection coverage.
- Current operational evidence and alert recency matter when diagnosing a live incident.
- Incorrect time conversion can hide existing evidence even when logging and retention are healthy.
Explanation
Correct Answer
B:The validation result should be: The confirmed incident is escalated promptly while duplicate noise is reduced and raw evidence stays searchable.
Incorrect Answers
A:This corresponds to a different condition: A security team receives an alert for outbound contact with a newly malicious destination but cannot identify which allow rule enabled it. The directly relevant correction here is: Prioritize the evidence-backed severe incident, then tune alert rules or suppressions narrowly without suppressing required logs.
