Question 70

A network security analyst needs exactly TWO case-specific control steps. A security team uses an external domain indicator feed, but configured it as an IP-list type and sees no intended domain matches. Which TWO actions directly belong to the safe diagnostic and remediation workflow? Select TWO answers.

  1. Competing correction: Correct the approved feed URL and trust or reachability prerequisites, then confirm a successful EDL refresh.
  2. Alternative verification: A newly added approved test URL receives the expected profile action after the EDL refresh interval.
  3. Alternative diagnostic: Compare the raw feed entries with import and type-validation warnings and the current resolved list.
  4. Apply correction: Configure the external dynamic list with the proper domain list type and use it in the supported domain-based policy control.
  5. Collect evidence: Review the list source's lines, configured EDL type, download errors and DNS/security matching evidence.

Explanation

Correct Answer

D:

The expected outcome is: A controlled listed domain is recognized after refresh while unrelated domains are unaffected. EDL entry type must match the indicator representation and the policy feature consuming it.

E:

Success is demonstrated when: A controlled listed domain is recognized after refresh while unrelated domains are unaffected. EDL entry type must match the indicator representation and the policy feature consuming it.

Incorrect Answers

A:

This corresponds to a different condition: A threat-intelligence vendor changes the EDL HTTPS endpoint and the firewall's last successful refresh is several days old. Competing correction: Correct the approved feed URL and trust or reachability prerequisites, then confirm a successful EDL refresh.

B:

This corresponds to a different condition: A managed phishing-URL feed updates hourly, but URL Filtering enforcement continues to use an old manually entered URL category. Alternative verification: A newly added approved test URL receives the expected profile action after the EDL refresh interval.

C:

This corresponds to a different condition: A global DNS-based EDL contains duplicate and malformed entries; an analyst assumes every line is active despite import warnings. The discriminating evidence is: Review the list source's lines, configured EDL type, download errors and DNS/security matching evidence.

Question 71

A supervisor is assessing the risks of a rushed remediation. A security team uses an external domain indicator feed, but configured it as an IP-list type and sees no intended domain matches. Which proposed shortcut should the analyst REJECT as unsafe or ineffective? Select ONE best answer.

  1. Review the list source's lines, configured EDL type, download errors and DNS/security matching evidence.
  2. Append domain names to an IP address object and expect them to be treated as IP literals.
  3. Configure the external dynamic list with the proper domain list type and use it in the supported domain-based policy control.
  4. A controlled listed domain is recognized after refresh while unrelated domains are unaffected.

Explanation

Correct Answer

B:

This is the unsafe proposal in the stated scenario because it bypasses the control boundary. The required principle is: EDL entry type must match the indicator representation and the policy feature consuming it.

Incorrect Answers

A:

This is a controlled and useful step for the described condition, not the unsafe shortcut. EDL entry type must match the indicator representation and the policy feature consuming it.

C:

This is a controlled and useful step for the described condition, not the unsafe shortcut. The shortcut to reject is: Append domain names to an IP address object and expect them to be treated as IP literals.

D:

This is a controlled and useful step for the described condition, not the unsafe shortcut. A controlled listed domain is recognized after refresh while unrelated domains are unaffected.

Question 72

A branch operations team must document a cause-based remediation with a measurable outcome. A security team uses an external domain indicator feed, but configured it as an IP-list type and sees no intended domain matches. What is the BEST complete investigation–change–verification plan? Select ONE best answer.

  1. Investigate: Review the list source's lines, configured EDL type, download errors and DNS/security matching evidence. Correct: Configure the external dynamic list with the proper domain list type and use it in the supported domain-based policy control. Verify: A controlled listed domain is recognized after refresh while unrelated domains are unaffected.
  2. Investigate: Compare the raw feed entries with import and type-validation warnings and the current resolved list. Correct: Validate and normalize the published indicator format, review EDL import status, and correct the source before relying on matches. Verify: The sanitized feed loads without rejected entries and a controlled indicator matches the intended enforcement.
  3. Investigate: Inspect the URL list fetch time, URL format, profile action and matching URL-filtering events. Correct: Define an external dynamic URL list, reference it in the appropriate URL Filtering policy/profile, and verify periodic retrieval. Verify: A newly added approved test URL receives the expected profile action after the EDL refresh interval.
  4. Investigate: Check HTTP retrieval errors, TLS or DNS reachability, and the EDL's last-update status. Correct: Correct the approved feed URL and trust or reachability prerequisites, then confirm a successful EDL refresh. Verify: The list downloads successfully and the latest indicator inventory becomes active for referenced policy.

Explanation

Correct Answer

A:

It avoids the unsupported shortcut: Append domain names to an IP address object and expect them to be treated as IP literals.

Incorrect Answers

B:

Compare the raw feed entries with import and type-validation warnings and the current resolved list. Correct: Validate and normalize the published indicator format, review EDL import status, and correct the source before relying on matches. Verify: The sanitized feed loads without rejected entries and a controlled indicator matches the intended enforcement. This corresponds to a different condition: A global DNS-based EDL contains duplicate and malformed entries; an analyst assumes every line is active despite import warnings. The current report has a distinct control gap; EDL entry type must match the indicator representation and the policy feature consuming it. The directly relevant correction here is: Configure the external dynamic list with the proper domain list type and use it in the supported domain-based policy control. The discriminating evidence is: Review the list source's lines, configured EDL type, download errors and DNS/security matching evidence.

C:

Inspect the URL list fetch time, URL format, profile action and matching URL-filtering events. Correct: Define an external dynamic URL list, reference it in the appropriate URL Filtering policy/profile, and verify periodic retrieval. Verify: A newly added approved test URL receives the expected profile action after the EDL refresh interval. This corresponds to a different condition: A managed phishing-URL feed updates hourly, but URL Filtering enforcement continues to use an old manually entered URL category. The current report has a distinct control gap; EDL entry type must match the indicator representation and the policy feature consuming it. The directly relevant correction here is: Configure the external dynamic list with the proper domain list type and use it in the supported domain-based policy control. The discriminating evidence is: Review the list source's lines, configured EDL type, download errors and DNS/security matching evidence.

D:

Check HTTP retrieval errors, TLS or DNS reachability, and the EDL's last-update status. Correct: Correct the approved feed URL and trust or reachability prerequisites, then confirm a successful EDL refresh. Verify: The list downloads successfully and the latest indicator inventory becomes active for referenced policy. This corresponds to a different condition: A threat-intelligence vendor changes the EDL HTTPS endpoint and the firewall's last successful refresh is several days old. The current report has a distinct control gap; EDL entry type must match the indicator representation and the policy feature consuming it. The directly relevant correction here is: Configure the external dynamic list with the proper domain list type and use it in the supported domain-based policy control. The discriminating evidence is: Review the list source's lines, configured EDL type, download errors and DNS/security matching evidence.

Question 73

A managed phishing-URL feed updates hourly, but URL Filtering enforcement continues to use an old manually entered URL category. The team is considering the shortcut: Treat the feed as a domain-only list and drop URL path information required for matching. Which policy or object change DIRECTLY addresses the case? Select ONE best answer.

  1. Define an external dynamic URL list, reference it in the appropriate URL Filtering policy/profile, and verify periodic retrieval.
  2. Treat the feed as a domain-only list and drop URL path information required for matching.
  3. Correct the approved feed URL and trust or reachability prerequisites, then confirm a successful EDL refresh.
  4. Validate and normalize the published indicator format, review EDL import status, and correct the source before relying on matches.

Explanation

Correct Answer

A:

URL-type EDLs can supply URLs for dynamic enforcement rather than requiring static URL category edits. This correction targets the observed gap rather than a neighboring symptom.

Incorrect Answers

B:

That option would treat the feed as a domain-only list and drop URL path information required for matching, but it addresses a different concern. This correction targets the observed gap rather than a neighboring symptom.

C:

This corresponds to a different condition: A threat-intelligence vendor changes the EDL HTTPS endpoint and the firewall's last successful refresh is several days old. The current report has a distinct control gap; URL-type EDLs can supply URLs for dynamic enforcement rather than requiring static URL category edits.

D:

This corresponds to a different condition: A global DNS-based EDL contains duplicate and malformed entries; an analyst assumes every line is active despite import warnings. The current report has a distinct control gap; URL-type EDLs can supply URLs for dynamic enforcement rather than requiring static URL category edits.

Question 74

In a Palo Alto Networks configuration review, the following condition is reported: A managed phishing-URL feed updates hourly, but URL Filtering enforcement continues to use an old manually entered URL category. The proposed correction is to define an external dynamic URL list, reference it in the appropriate URL Filtering policy/profile, and verify periodic retrieval. Which technical principle BEST explains why this correction is appropriate? Select ONE best answer.

  1. A referenced EDL cannot supply fresh indicators if its remote source is unreachable or not correctly formatted.
  2. URL-type EDLs can supply URLs for dynamic enforcement rather than requiring static URL category edits.
  3. An external dynamic list allows matching rules to consume periodically updated indicators without hand-editing every IP.
  4. List import warnings and content validation directly affect which EDL indicators are usable.

Explanation

Correct Answer

B:

Relevant evidence: Inspect the URL list fetch time, URL format, profile action and matching URL-filtering events.

Incorrect Answers

A:

This corresponds to a different condition: A threat-intelligence vendor changes the EDL HTTPS endpoint and the firewall's last successful refresh is several days old. The directly relevant correction here is: Define an external dynamic URL list, reference it in the appropriate URL Filtering policy/profile, and verify periodic retrieval.

C:

This corresponds to a different condition: An incident team supplies a regularly updated IP block feed, but security policy still lists yesterday's addresses manually. The current report has a distinct control gap; URL-type EDLs can supply URLs for dynamic enforcement rather than requiring static URL category edits.

D:

This corresponds to a different condition: A global DNS-based EDL contains duplicate and malformed entries; an analyst assumes every line is active despite import warnings. The directly relevant correction here is: Define an external dynamic URL list, reference it in the appropriate URL Filtering policy/profile, and verify periodic retrieval.

Question 75

An analyst must collect precise technical evidence before changing configuration. A managed phishing-URL feed updates hourly, but URL Filtering enforcement continues to use an old manually entered URL category. Which investigation would BEST isolate this specific mismatch? Select ONE best answer.

  1. Inspect the URL list fetch time, URL format, profile action and matching URL-filtering events.
  2. Check HTTP retrieval errors, TLS or DNS reachability, and the EDL's last-update status.
  3. Check feed retrieval state, list contents, match type and security rule references.
  4. Compare the raw feed entries with import and type-validation warnings and the current resolved list.

Explanation

Correct Answer

A:

URL-type EDLs can supply URLs for dynamic enforcement rather than requiring static URL category edits. These checks distinguish the actual cause before changes are attempted.

Incorrect Answers

B:

This corresponds to a different condition: A threat-intelligence vendor changes the EDL HTTPS endpoint and the firewall's last successful refresh is several days old. The discriminating evidence is: Inspect the URL list fetch time, URL format, profile action and matching URL-filtering events.

C:

This corresponds to a different condition: An incident team supplies a regularly updated IP block feed, but security policy still lists yesterday's addresses manually. The directly relevant correction here is: Define an external dynamic URL list, reference it in the appropriate URL Filtering policy/profile, and verify periodic retrieval.

D:

The discriminating evidence is: Inspect the URL list fetch time, URL format, profile action and matching URL-filtering events.

Question 76

The approved controlled change was applied to this situation: A managed phishing-URL feed updates hourly, but URL Filtering enforcement continues to use an old manually entered URL category. The change was to define an external dynamic URL list, reference it in the appropriate URL Filtering policy/profile, and verify periodic retrieval. Which verification result most directly demonstrates success? Select ONE best answer.

  1. The list downloads successfully and the latest indicator inventory becomes active for referenced policy.
  2. A newly added approved test URL receives the expected profile action after the EDL refresh interval.
  3. A newly published test indicator appears after refresh and matches the expected block action.
  4. The sanitized feed loads without rejected entries and a controlled indicator matches the intended enforcement.

Explanation

Correct Answer

B:

URL-type EDLs can supply URLs for dynamic enforcement rather than requiring static URL category edits. This is the observable acceptance result for the exact reported problem.

Incorrect Answers

A:

This corresponds to a different condition: A threat-intelligence vendor changes the EDL HTTPS endpoint and the firewall's last successful refresh is several days old. The list downloads successfully and the latest indicator inventory becomes active for referenced policy.

C:

This corresponds to a different condition: An incident team supplies a regularly updated IP block feed, but security policy still lists yesterday's addresses manually. A newly published test indicator appears after refresh and matches the expected block action.

Question 79

A threat-intelligence vendor changes the EDL HTTPS endpoint and the firewall's last successful refresh is several days old. The team is considering the shortcut: Disable all indicator-based blocking permanently because the feed briefly failed. Which policy or object change DIRECTLY addresses the case? Select ONE best answer.

  1. Create an external dynamic IP list sourced from the approved feed, reference it in the relevant block policy, and monitor refresh.
  2. Validate and normalize the published indicator format, review EDL import status, and correct the source before relying on matches.
  3. Disable all indicator-based blocking permanently because the feed briefly failed.
  4. Correct the approved feed URL and trust or reachability prerequisites, then confirm a successful EDL refresh.

Explanation

Correct Answer

D:

A referenced EDL cannot supply fresh indicators if its remote source is unreachable or not correctly formatted. This correction targets the observed gap rather than a neighboring symptom.

Incorrect Answers

A:
