Palo Alto Networks NetSec-Analyst Practice Test 3
Question 20
A network security analyst needs exactly TWO case-specific control steps. A university accepts encrypted web browsing but must enforce categories for known phishing destinations; the existing security profile group omits URL filtering. Which TWO actions directly belong to the safe diagnostic and remediation workflow? Select TWO answers.
- Alternative diagnostic: Check DNS and threat logs for the workstation, the anti-spyware profile group, and the specific spyware signature action.
- Competing correction: Add a suitable antivirus profile to a security profile group, attach that group to the matching allow rule, and deploy the change.
- Collect evidence: Review URL filtering profile actions, URL logs, and actual policy rule hits for the tested browser session.
- Apply correction: Configure an appropriate URL Filtering profile and attach it through the profile group on the relevant allow rule.
- Alternative verification: A supported safe test sample follows the submission workflow and the resulting verdict is visible without disrupting allowed content.
Explanation
Correct Answer
C:A URL category can be permitted or blocked by a URL Filtering profile, subject to visibility and encrypted-traffic constraints. These checks distinguish the actual cause before changes are attempted.
D:A URL category can be permitted or blocked by a URL Filtering profile, subject to visibility and encrypted-traffic constraints. The expected outcome is: Known phishing-category destinations receive the intended category response while normal academic browsing continues.
Incorrect Answers
A:This corresponds to a different condition: A regional retailer receives repeated spyware callbacks to suspicious domains from an infected store workstation, while its allow rule has no anti-spyware controls. The current report has a distinct control gap; A URL category can be permitted or blocked by a URL Filtering profile, subject to visibility and encrypted-traffic constraints.
B:This corresponds to a different condition: A hospital permits web access through an outbound allow rule, but malware downloads traverse without antivirus signatures being applied. The directly relevant correction here is: Configure an appropriate URL Filtering profile and attach it through the profile group on the relevant allow rule.
E:This corresponds to a different condition: A design studio permits approved cloud file transfers but has no WildFire-related analysis configured for newly seen executable samples. The directly relevant correction here is: Configure an appropriate URL Filtering profile and attach it through the profile group on the relevant allow rule.
Question 21
An analyst must collect precise technical evidence before changing configuration. A university accepts encrypted web browsing but must enforce categories for known phishing destinations; the existing security profile group omits URL filtering. Which investigation would BEST isolate this specific mismatch? Select ONE best answer.
- Review URL filtering profile actions, URL logs, and actual policy rule hits for the tested browser session.
- Check file-submission settings, license status, the rule's profile group, and WildFire submission and verdict logs.
- Check DNS and threat logs for the workstation, the anti-spyware profile group, and the specific spyware signature action.
- Compare the allow rule's profile-group attachment with antivirus verdicts and threat-log records for controlled test traffic.
Explanation
Correct Answer
A:A URL category can be permitted or blocked by a URL Filtering profile, subject to visibility and encrypted-traffic constraints. Success is demonstrated when: Known phishing-category destinations receive the intended category response while normal academic browsing continues.

Question 22
The approved controlled change was applied to this situation: A university accepts encrypted web browsing but must enforce categories for known phishing destinations; the existing security profile group omits URL filtering. The change was to configure an appropriate URL Filtering profile and attach it through the profile group on the relevant allow rule. Which verification result most directly demonstrates success? Select ONE best answer.
- Known phishing-category destinations receive the intended category response while normal academic browsing continues.
- A supported safe test sample follows the submission workflow and the resulting verdict is visible without disrupting allowed content.
- Controlled known-bad DNS requests trigger the selected alert, block, or sinkhole response without blanket DNS failure.
- Benign test file transfers remain permitted while known test malware is detected according to the profile action.
Explanation

Question 23
A supervisor is assessing the risks of a rushed remediation. A university accepts encrypted web browsing but must enforce categories for known phishing destinations; the existing security profile group omits URL filtering. Which proposed shortcut should the analyst REJECT as unsafe or ineffective? Select ONE best answer.
- Use a broad block of all HTTPS traffic instead of category-aware enforcement.
- Review URL filtering profile actions, URL logs, and actual policy rule hits for the tested browser session.
- Configure an appropriate URL Filtering profile and attach it through the profile group on the relevant allow rule.
- Known phishing-category destinations receive the intended category response while normal academic browsing continues.
Explanation
Correct Answer
A:This is the unsafe proposal in the stated scenario because it bypasses the control boundary. The required principle is: A URL category can be permitted or blocked by a URL Filtering profile, subject to visibility and encrypted-traffic constraints.
Incorrect Answers
B:This is a controlled and useful step for the described condition, not the unsafe shortcut. The shortcut to reject is: Use a broad block of all HTTPS traffic instead of category-aware enforcement.
C:This is a controlled and useful step for the described condition, not the unsafe shortcut. A URL category can be permitted or blocked by a URL Filtering profile, subject to visibility and encrypted-traffic constraints.
D:This is a controlled and useful step for the described condition, not the unsafe shortcut. Known phishing-category destinations receive the intended category response while normal academic browsing continues.

Question 25
A design studio permits approved cloud file transfers but has no WildFire-related analysis configured for newly seen executable samples. The team is considering the shortcut: Treat a new file's absence from a static antivirus signature as proof that it is harmless. Which policy or object change DIRECTLY addresses the case? Select ONE best answer.
- Include the required WildFire analysis profile in the allowed file-transfer rule's security profile group and confirm subscription readiness.
- Assign an anti-spyware profile with appropriate DNS-security or sinkholing behavior through the Security rule's profile group.
- Treat a new file's absence from a static antivirus signature as proof that it is harmless.
- Add a suitable antivirus profile to a security profile group, attach that group to the matching allow rule, and deploy the change.
Explanation
Correct Answer
A:WildFire analysis can submit supported unknown samples for verdicting; a profile must be applied to the relevant allowed traffic. This correction targets the observed gap rather than a neighboring symptom.
Incorrect Answers
B:This corresponds to a different condition: A regional retailer receives repeated spyware callbacks to suspicious domains from an infected store workstation, while its allow rule has no anti-spyware controls. The current report has a distinct control gap; WildFire analysis can submit supported unknown samples for verdicting; a profile must be applied to the relevant allowed traffic.
C:That option would treat a new file's absence from a static antivirus signature as proof that it is harmless, but it addresses a different concern. This correction targets the observed gap rather than a neighboring symptom.
D:This corresponds to a different condition: A hospital permits web access through an outbound allow rule, but malware downloads traverse without antivirus signatures being applied. The current report has a distinct control gap; WildFire analysis can submit supported unknown samples for verdicting; a profile must be applied to the relevant allowed traffic.
Question 26
In a Palo Alto Networks configuration review, the following condition is reported: A design studio permits approved cloud file transfers but has no WildFire-related analysis configured for newly seen executable samples. The proposed correction is to include the required WildFire analysis profile in the allowed file-transfer rule's security profile group and confirm subscription readiness. Which technical principle BEST explains why this correction is appropriate? Select ONE best answer.
- Vulnerability profiles are content-inspection controls, not substitutes for the rule's permit decision.
- Security profiles inspect traffic only after an allow rule matches; defining a profile alone is not enforcement.
- WildFire analysis can submit supported unknown samples for verdicting; a profile must be applied to the relevant allowed traffic.
- Anti-spyware detection and DNS controls apply to allowed sessions only when the relevant profile is enforced by matching policy.
Explanation
Correct Answer
C:The validation result should be: A supported safe test sample follows the submission workflow and the resulting verdict is visible without disrupting allowed content.
Incorrect Answers
A:This corresponds to a different condition: An engineering portal is reachable through an inbound allow rule, but exploit signatures are not evaluated on HTTP requests to the exposed server.
