Question 57:
In question 57, after a new feature release users experience latency at login. The first action should be to rollback the recent release to the previous stable version.
Why:

• Rolling back quickly restores service and user experience, minimizing impact (blast radius) while you investigate the root cause.
• It buys time to diagnose whether the regression was introduced by the new release.

• Review Stackdriver monitoring is important for diagnosis, but it doesn’t immediately restore service to normal. Do it after rollback or in parallel to triage.
• Upsize the VMs may help temporarily but does not address the underlying issue and isn’t a guaranteed fix.
• Deploy a new release could reintroduce the problem or delay stabilization.

Hi, when I click on Practice online it sends me to the free test is this right? is there a Mac OS of Xengine Thanks Mark

Question 2:

• Correct option: C — the models are PA-3260, PA-5410, PA-850, and PA-460.
• Why: ARE requires PAN-OS 11.0+ and hardware that supports the feature. ARE is available on the PA-3200 Series, PA-5400 Series, PA-800 Series, and PA-400 Series. That includes:

• What to do in practice:

• Why other choices are incorrect: those models fall outside the ARE-supported families or are VM/CN-Series not listed for ARE in this context.

Question 2:

• Correct answer: Set-MsolCompanySettings

• Why:

Question 0:
You’re right to question it, but in this exam context the correct option is A: create_resource("res1", "ComputerVision", "F0", "westus").
Why:

• The task is to generate captions of images, which uses the Computer Vision resource, not Custom Vision.
• The requirement specifies a free Azure resource, so you should use the free tier F0 in the West US region.
• The other options either use the wrong service (CustomVision.Prediction) or a paid tier (S0).

Question 17:

• Correct answer: A

• Why: To generate captions of images, you need a ComputerVision resource, not CustomVision.Prediction. The task specifies a free Azure resource, so use the free tier F0 and set the location to westus. The other options either use the wrong service (Custom Vision) or use a paid tier (S0). The function call should be:

Question 46:

• The correct completion is: collection of information concepts and their relationships to one another.

• In TOGAF/Enterprise Architecture, an information map is a visual representation of the information landscape. It shows what information assets exist, where they reside, and how they relate and flow between systems. It helps identify key data concepts, their locations, and the dependencies between them.

Question 1810:

• Correct answer: C — User acceptance testing (UAT)

• Why: In year two, business processes are updated to implement new functionality. UAT verifies that the new functionality meets business requirements, is usable by end users, and supports necessary controls and reporting. It provides the final confirmation before go-live.

• Why the others are weaker:

• Practical tip: base UAT on real business scenarios, ensure the UAT environment mirrors production, require business owner sign-off, and maintain traceability between requirements and test cases.

Question 1807:

• Correct answer: D — Previous system interface testing records

• Why: since the two business-critical systems haven’t been tested since implementation, the most relevant evidence for planning an audit is what was previously tested on the interfaces between those systems. These records show the actual interface test scope, data mappings, validation rules, error handling, and reconciliation checks, and help identify gaps to address during the audit.

• Why others are weaker:

• Practical tip: use the records to define test objectives, identify missing interface controls, and plan targeted re-testing or validation of data integrity across the interfaces.

Question 1813:
Correct answer: C

• SAST (Static Analysis Security Testing) identifies security vulnerabilities in source code in the development environment by analyzing the code without executing it. It’s typically integrated into the SDLC (e.g., during coding or CI/CD) to catch issues early.

• DAST (Dynamic Analysis Security Testing) tests a running application from an external perspective to find runtime vulnerabilities, not the source code.
• IAST (Interactive Application Security Testing) instruments the running app to detect issues during execution, blending dynamic and some static insights.
• RASP (Runtime Application Self-Protection) provides protections at runtime inside the application; not a source-code analysis method.
