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:
- Content Moderator is for content safety/moderation, not tagging. - Image Moderation endpoints focus on inappropriate content. - Custom Translator translates text, not image tags.
In short, use the Image Analysis endpoint to get language-localized tags with minimal effort.

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:
- Bot Framework Composer is a design/authoring tool, not a local validation tool for a running bot. - Registering the bot with Azure Bot Service is for cloud deployment, not for initial local validation. - Windows Terminal is just a shell; it doesn’t provide bot testing capabilities.
  • Quick steps (before connecting to channels):
- Install and run the bot locally (e.g., dotnet run or npm start). - Start the Bot Framework Emulator and connect to your bot’s local endpoint (typically http://localhost:3978/api/messages with any app credentials as needed). - Validate conversations, dialogs, and state to ensure correct behavior prior to deployment.

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.

Why not the other options as the first step:
  • 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.

Best practice tip: use feature flags or canary deployments so you can rollback a feature with minimal impact, and have a defined rollback playbook for fast incident response.

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:
- PA-3260 (PA-3200 family) - PA-5410 (PA-5400 family) - PA-850 and PA-460 (PA-800/PA-400 families)
  • What to do in practice:
- Ensure PAN-OS 11.0+ is running. - Apply the ARE license. - Enable ARE on the relevant logical router to use advanced routing features (e.g., enhanced BGP/OSPF).
  • 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:
- Self-service sign-up (SSS) is a tenant-wide setting in Azure AD/MSOL. To prevent external users from creating new accounts in your contoso.com tenant via SSS, you modify the MSOL company settings. - The cmdlet to configure these tenant-wide settings is Set-MsolCompanySettings. - The other options operate on federation settings or domain-level configurations (e.g., Set-MsolDomainFederationSettings, Update-MsolfederatedDomain, Set-MsolDomain) and do not control self-service sign-up behavior.

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).

If you’ve seen F0 not available for Computer Vision in your actual Azure portal, that’s a portal/region nuance, but for the exam scenario the expected choice is A.

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:
create_resource("res1", "ComputerVision", "F0", "westus")
