Palo Alto Networks NetSec-Analyst Practice Test 10

Question 90

A network security analyst needs exactly TWO case-specific control steps. A global DNS-based EDL contains duplicate and malformed entries; an analyst assumes every line is active despite import warnings. Which TWO actions directly belong to the safe diagnostic and remediation workflow? Select TWO answers.

  1. Alternative diagnostic: Inspect the URL list fetch time, URL format, profile action and matching URL-filtering events.
  2. Competing correction: Configure the external dynamic list with the proper domain list type and use it in the supported domain-based policy control.
  3. Alternative verification: A newly published test indicator appears after refresh and matches the expected block action.
  4. Collect evidence: Compare the raw feed entries with import and type-validation warnings and the current resolved list.
  5. Apply correction: Validate and normalize the published indicator format, review EDL import status, and correct the source before relying on matches.

Explanation

Correct Answer

D:

If confirmed, the narrowly scoped remedy is: Validate and normalize the published indicator format, review EDL import status, and correct the source before relying on matches. Success is demonstrated when: The sanitized feed loads without rejected entries and a controlled indicator matches the intended enforcement.

E:

The expected outcome is: The sanitized feed loads without rejected entries and a controlled indicator matches the intended enforcement. List import warnings and content validation directly affect which EDL indicators are usable.

Incorrect Answers

A:

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

B:

This corresponds to a different condition: A security team uses an external domain indicator feed, but configured it as an IP-list type and sees no intended domain matches. Competing correction: Configure the external dynamic list with the proper domain list type and use it in the supported domain-based policy control.

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. Alternative verification: A newly published test indicator appears after refresh and matches the expected block action.

Question 91

A research network needs to exempt a single approved medical repository URL path, but generic URL category rules are too broad. The team is considering the shortcut: Move the entire medical-information URL category to unrestricted allow for every user. Which policy or object change DIRECTLY addresses the case? Select ONE best answer.

  1. Create a narrowly scoped custom URL category containing the approved destination and reference it in the appropriate URL policy.
  2. Define a scoped custom data pattern, validate its expression with synthetic values, and incorporate it in the applicable filtering profile.
  3. Move the entire medical-information URL category to unrestricted allow for every user.
  4. Define a supported custom application signature after documenting its traffic pattern, then restrict a matching rule to that App-ID.

Explanation

Correct Answer

A:

The expected outcome is: Only the approved repository URL path gets the intended category action while other destinations retain controls.

Incorrect Answers

B:

This corresponds to a different condition: A health insurer wants to identify a unique internal patient reference number pattern within outgoing documents. The current report has a distinct control gap; Custom URL categories express site-specific policy exceptions without globally weakening a broad content category.

C:

Move the entire medical-information URL category to unrestricted allow for every user. This is the shortcut under scrutiny. In this case it fails because: Custom URL categories express site-specific policy exceptions without globally weakening a broad content category. A safe correction instead is: Create a narrowly scoped custom URL category containing the approved destination and reference it in the appropriate URL policy. Verify using: Inspect the custom category membership, URL profile match, and test URL filtering log detail.

D:

This corresponds to a different condition: An internal manufacturing protocol uses a distinctive payload signature not recognized by App-ID, while port-based rules overpermit unrelated traffic. The current report has a distinct control gap; Custom URL categories express site-specific policy exceptions without globally weakening a broad content category.

Question 92

In a Palo Alto Networks configuration review, the following condition is reported: A research network needs to exempt a single approved medical repository URL path, but generic URL category rules are too broad. The proposed correction is to create a narrowly scoped custom URL category containing the approved destination and reference it in the appropriate URL policy. Which technical principle BEST explains why this correction is appropriate? Select ONE best answer.

  1. Address groups reduce repeated object maintenance but still require correct rule scope and target-zone matching.
  2. Custom application identification can narrow access to a recognized proprietary protocol rather than trusting a port alone.
  3. Custom URL categories express site-specific policy exceptions without globally weakening a broad content category.
  4. A custom pattern identifies sensitive content; detection becomes effective only through a corresponding enforced profile and policy.

Explanation

Correct Answer

C:

The validation result should be: Only the approved repository URL path gets the intended category action while other destinations retain controls.

Incorrect Answers

A:

This corresponds to a different condition: A logistics company changes its private shipping-service subnet weekly and multiple rules repeat the same literal host addresses. The current report has a distinct control gap; Custom URL categories express site-specific policy exceptions without globally weakening a broad content category.

B:

This corresponds to a different condition: An internal manufacturing protocol uses a distinctive payload signature not recognized by App-ID, while port-based rules overpermit unrelated traffic. The directly relevant correction here is: Create a narrowly scoped custom URL category containing the approved destination and reference it in the appropriate URL policy.

D:

This corresponds to a different condition: A health insurer wants to identify a unique internal patient reference number pattern within outgoing documents. The directly relevant correction here is: Create a narrowly scoped custom URL category containing the approved destination and reference it in the appropriate URL policy.

Question 93

An analyst must collect precise technical evidence before changing configuration. A research network needs to exempt a single approved medical repository URL path, but generic URL category rules are too broad. Which investigation would BEST isolate this specific mismatch? Select ONE best answer.

  1. Inspect the custom category membership, URL profile match, and test URL filtering log detail.
  2. Check the address-group member set, source/destination fields of referencing rules, and hit logs.
  3. Review sample traffic, the custom application's signature match and the actual application shown in traffic logs.
  4. Review the data pattern expression, sample matches, exclusions and profile attachment on allowed file transfers.

Explanation

Correct Answer

A:

Success is demonstrated when: Only the approved repository URL path gets the intended category action while other destinations retain controls.

Incorrect Answers

B:

This corresponds to a different condition: A logistics company changes its private shipping-service subnet weekly and multiple rules repeat the same literal host addresses. The directly relevant correction here is: Create a narrowly scoped custom URL category containing the approved destination and reference it in the appropriate URL policy.

C:

This corresponds to a different condition: An internal manufacturing protocol uses a distinctive payload signature not recognized by App-ID, while port-based rules overpermit unrelated traffic. The discriminating evidence is: Inspect the custom category membership, URL profile match, and test URL filtering log detail.

D:

This corresponds to a different condition: A health insurer wants to identify a unique internal patient reference number pattern within outgoing documents. Review the data pattern expression, sample matches, exclusions and profile attachment on allowed file transfers.

Question 94

The approved controlled change was applied to this situation: A research network needs to exempt a single approved medical repository URL path, but generic URL category rules are too broad. The change was to create a narrowly scoped custom URL category containing the approved destination and reference it in the appropriate URL policy. Which verification result most directly demonstrates success? Select ONE best answer.

  1. Only the approved repository URL path gets the intended category action while other destinations retain controls.
  2. The proprietary session is classified and allowed while unrelated sessions on the same port are denied.
  3. Synthetic matching identifiers are detected, while look-alike but nonmatching values do not generate the same incident.
  4. Traffic from the approved shipping hosts matches the intended policies while an unlisted test host does not.

Explanation

Correct Answer

A:

Custom URL categories express site-specific policy exceptions without globally weakening a broad content category.

Incorrect Answers

B:

This corresponds to a different condition: An internal manufacturing protocol uses a distinctive payload signature not recognized by App-ID, while port-based rules overpermit unrelated traffic. The proprietary session is classified and allowed while unrelated sessions on the same port are denied.

C:

This corresponds to a different condition: A health insurer wants to identify a unique internal patient reference number pattern within outgoing documents. Synthetic matching identifiers are detected, while look-alike but nonmatching values do not generate the same incident.

D:

This corresponds to a different condition: A logistics company changes its private shipping-service subnet weekly and multiple rules repeat the same literal host addresses. Traffic from the approved shipping hosts matches the intended policies while an unlisted test host does not.

Question 95

A supervisor is assessing the risks of a rushed remediation. A research network needs to exempt a single approved medical repository URL path, but generic URL category rules are too broad. Which proposed shortcut should the analyst REJECT as unsafe or ineffective? Select ONE best answer.

  1. Create a narrowly scoped custom URL category containing the approved destination and reference it in the appropriate URL policy.
  2. Inspect the custom category membership, URL profile match, and test URL filtering log detail.
  3. Only the approved repository URL path gets the intended category action while other destinations retain controls.
  4. Move the entire medical-information URL category to unrestricted allow for every user.

Explanation

Correct Answer

D:

This is the unsafe proposal in the stated scenario because it bypasses the control boundary. The required principle is: Custom URL categories express site-specific policy exceptions without globally weakening a broad content category.

Incorrect Answers

A:

This is a controlled and useful step for the described condition, not the unsafe shortcut. Custom URL categories express site-specific policy exceptions without globally weakening a broad content category.

B:

This is a controlled and useful step for the described condition, not the unsafe shortcut. The shortcut to reject is: Move the entire medical-information URL category to unrestricted allow for every user.

C:

This is a controlled and useful step for the described condition, not the unsafe shortcut. Only the approved repository URL path gets the intended category action while other destinations retain controls.

Question 96

A branch operations team must document a cause-based remediation with a measurable outcome. A research network needs to exempt a single approved medical repository URL path, but generic URL category rules are too broad. What is the BEST complete investigation–change–verification plan? Select ONE best answer.

  1. Investigate: Review the data pattern expression, sample matches, exclusions and profile attachment on allowed file transfers. Correct: Define a scoped custom data pattern, validate its expression with synthetic values, and incorporate it in the applicable filtering profile. Verify: Synthetic matching identifiers are detected, while look-alike but nonmatching values do not generate the same incident.
  2. Investigate: Check the address-group member set, source/destination fields of referencing rules, and hit logs. Correct: Create a managed address-group object for the shipping hosts and reference it in the scoped security policies. Verify: Traffic from the approved shipping hosts matches the intended policies while an unlisted test host does not.
  3. Investigate: Inspect the custom category membership, URL profile match, and test URL filtering log detail. Correct: Create a narrowly scoped custom URL category containing the approved destination and reference it in the appropriate URL policy. Verify: Only the approved repository URL path gets the intended category action while other destinations retain controls.
  4. Investigate: Review sample traffic, the custom application's signature match and the actual application shown in traffic logs. Correct: Define a supported custom application signature after documenting its traffic pattern, then restrict a matching rule to that App-ID. Verify: The proprietary session is classified and allowed while unrelated sessions on the same port are denied.
