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")

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:
- Data migration: important, but primarily a year-one activity focused on moving data, not validating the new functionality. - Sociability testing: (not a standard term here) generally would cover technical or integration aspects rather than end-user acceptance of new processes. - Initial user access provisioning: security setup; important but not the primary focus for validating updated business processes.
  • 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:
- Quality assurance (QA) testing: broad quality checks, not specifically focused on the data-transfer interfaces. - System change logs: show changes but not whether interfaces were tested or validated. - IT testing policies and procedures: provide governance guidance, not concrete evidence of past interface testing.
  • 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.

Why the others are less appropriate for this scenario:
  • 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.

Question 1811:
Correct answer: D
Reason:

  • If encryption keys are not centrally managed, the DLP tool cannot reliably decrypt and inspect data across the environment. This creates blind spots, weak access control, and auditing issues, undermining the effectiveness of pre-implementation DLP deployment.

Why the others are less critical in this context:
  • Monitor mode vs block mode affects enforcement; monitor-only reduces effectiveness but is not as fundamental a risk as broken key management.
  • Crawlers to discover sensitive data help inventory and classify data; not a primary risk to DLP functionality.
  • Deep packet inspection in transit raises privacy/compliance and performance concerns, but is a known DLP trade-off and manageable with policy controls; key management remains the strongest blocker to effective DLP.

Question 121:

  • Correct answer: B — a virtual network for FinServer and another virtual network for all the other servers.

  • Why:
- In Azure, network segmentation is done with VNets. Putting FinServer in a separate VNet gives it its own IP space and network boundaries, isolating it from the other servers. - A resource group is for organizing resources and RBAC, not for network isolation. - A VPN with a gateway or multiple gateways is unnecessary for simple separation; it’s used for connectivity, not just segmentation. - One resource group with a lock does not affect network isolation.
  • Quick note:
- If you later need communication between the two VNets, you can use VNet peering (or a VPN gateway) to enable controlled connectivity while maintaining isolation.

Question 86:

  • Correct answer: Vertical scaling

  • Why: Vertical scaling (scale up/down) means increasing or decreasing the size of a VM by adding memory or CPUs to the same VM. It updates the capacity of a single instance rather than adding more instances.

  • How it compares to other terms:
- Horizontal scaling (scale out/in): changes the number of VM instances, not the size of each one. - Elasticity: broad concept of adapting resources to demand (includes vertical and horizontal scaling). - Agility: general capability; not specific to VM capacity.
  • Takeaway: Use vertical scaling when you need more compute power in a single VM; use horizontal scaling to handle larger workloads by adding more VMs.
