Question 1

At Woodgrove Bank, the network security team needs to upgrade PAN-OS on a production firewall with minimal avoidable risk. Which approach best meets the requirement?

• Coordinate firewall software/content maintenance with the hosting or orchestration platform and confirm traffic-path resiliency
• Use change control, validate the match criteria and dependencies, commit in a controlled window, and verify logs and application behavior
• Maintain the appropriate dynamic content updates and verify update jobs complete successfully
• Use security profile groups or equivalent policy constructs and verify they are attached to the intended allow rules
• Review release guidance and prerequisites, back up configuration/state as appropriate, follow the supported upgrade path, and validate service after the change

Correct answer: E

Explanation

1. Software and cloud-native firewalls depend on both PAN-OS behavior and the platform that provides compute, networking, or orchestration. This can be valid in another context, but it does not directly satisfy the stated requirement(s): upgrade PAN-OS on a production firewall with minimal avoidable risk.
2. Policy changes should be reviewed and tested with observable post-change evidence. This can be valid in another context, but it does not directly satisfy the stated requirement(s): upgrade PAN-OS on a production firewall with minimal avoidable risk.
3. Current content enables the firewall to recognize new applications and threats and is a core maintenance responsibility. This can be valid in another context, but it does not directly satisfy the stated requirement(s): upgrade PAN-OS on a production firewall with minimal avoidable risk.
4. Profiles only protect traffic when the matching rule invokes them, so attachment and validation matter as much as profile creation. This can be valid in another context, but it does not directly satisfy the stated requirement(s): upgrade PAN-OS on a production firewall with minimal avoidable risk.
5. Controlled upgrades require prerequisites, backups, supported sequencing, and post-change validation rather than installing a version blindly. This directly satisfies one of the stated requirement(s).

Learning point: NETSEC-T15-Q001: Review release guidance and prerequisites, back up configuration/state as appropriate, follow the supported upgrade path, and validate service after the change.

Question 19

During a design review for Woodgrove Bank, the requirement is to avoid running unsupported software indefinitely because it appears stable. Which choice is most appropriate?

• Review release guidance and prerequisites, back up configuration/state as appropriate, follow the supported upgrade path, and validate service after the change
• Maintain the appropriate dynamic content updates and verify update jobs complete successfully
• Use change control, validate the match criteria and dependencies, commit in a controlled window, and verify logs and application behavior
• Track software lifecycle, security advisories, and supported release guidance and plan upgrades before support or exposure becomes critical
• Use security profile groups or equivalent policy constructs and verify they are attached to the intended allow rules

Correct answer: D

Explanation

1. Controlled upgrades require prerequisites, backups, supported sequencing, and post-change validation rather than installing a version blindly. This can be valid in another context, but it does not directly satisfy the stated requirement(s): avoid running unsupported software indefinitely because it appears stable.
2. Current content enables the firewall to recognize new applications and threats and is a core maintenance responsibility. This can be valid in another context, but it does not directly satisfy the stated requirement(s): avoid running unsupported software indefinitely because it appears stable.
3. Policy changes should be reviewed and tested with observable post-change evidence. This can be valid in another context, but it does not directly satisfy the stated requirement(s): avoid running unsupported software indefinitely because it appears stable.
4. Maintenance includes lifecycle and vulnerability management, not just reacting after an outage occurs. This directly satisfies one of the stated requirement(s).
