Exam-Day Strategies

On the day of the exam, it's crucial to approach it with a focused mindset and a clear strategy. Here are some tips to help you perform your best:

  1. Read and Understand the Questions: Carefully read each question and its options. Understand what is being asked before selecting your answer. Be cautious of keywords or phrases that may change the context or scope of the question.
  2. Manage Your Time: Pace yourself throughout the exam to ensure you have sufficient time to answer all the questions. If you encounter a difficult question, consider flagging it and revisiting it later to avoid spending too much time on a single item.
  3. Eliminate Incorrect Options: If you're unsure about the correct answer, eliminate the options that you know are incorrect. This increases your chances of selecting the right answer even if you're unsure.
  4. Answer Every Question: There are no penalties for incorrect answers, so make sure to provide a response for every question. Even if you're uncertain, it's better to make an educated guess than to leave a question unanswered.
  5. Review Your Answers: If time permits, review your answers before submitting the exam. Look for any errors or inconsistencies that you might have missed during the initial attempt.

By following these strategies and investing ample time in thorough preparation, you can increase your chances of passing the PEGAPCDS80V1_2020 exam and earning the valuable Pega Certified Data Scientist certification.

Remember, success comes with persistence and a growth mindset. Believe in yourself, stay focused, and embrace the learning journey.

Best of luck on your PEGAPCDS80V1_2020 exam!

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")
