Question 28:
Answer: C — Computer Vision image analysis
Explanation:

• To generate image tags in multiple languages with minimal development, use the Image Analysis endpoint of the Computer Vision service.
• Call the API (Analyze Image) with visualFeatures=Tags and specify the language parameter (e.g., language=en, language=fr, language=es). The response returns tags with names localized to the requested language.
• This approach requires no custom model training, unlike Custom Vision image classification, which would require building and tagging a dataset.
• Other options:

Question 61:

• Correct answer: A. Run the Bot Framework Emulator.

• Why: The Bot Framework Emulator lets you test and validate a locally running bot before connecting to any channels. It lets you simulate conversations, inspect requests/responses, view state, and debug dialog flows in real time.

• Why the other options are not correct for pre-connection validation:

• Quick steps (before connecting to channels):

Question 10:
Correct answer: B. A new query key was generated.
Explanation:

• The REST call uses POST to .../regenerateKey with body {"keyName": "Key2"}. This regenerates only the specified key (Key2) for the given Cognitive Services account.
• The value of Key2 changes to a new secret; Key1 remains unchanged. It does not rotate both keys, nor does it involve Azure Key Vault.
• After regenerating, update your client applications to use the new Key2 value to continue authenticating.

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:
