Question 670
A production state file is stored locally on a developer laptop without backup or access control. Which risk is directly created by the described failure?
- State corruption can trigger destructive infrastructure changes or leak sensitive attributes.
- Unreviewed IaC effects can interrupt services or delete data despite a green pipeline parse.
- Configuration drift can disable monitoring or create inconsistent vulnerability exposure across servers.
- Template duplication and hardcoded scopes can introduce policy drift or unintended resource replacement.
Explanation
Correct Answer
A:State corruption can trigger destructive infrastructure changes or leak sensitive attributes. This is the directly relevant business or security consequence of terraform state lock and controlled backend for azure. Root cause: Terraform state represents actual managed resources and needs concurrency and confidentiality controls.
Incorrect Answers
B:Unreviewed IaC effects can interrupt services or delete data despite a green pipeline parse. That risk is relevant to arm template what-if detecting unintended replacements, but the specific unresolved condition here concerns terraform state lock and controlled backend for azure and has a different direct consequence.
C:Configuration drift can disable monitoring or create inconsistent vulnerability exposure across servers. That risk is relevant to azure machine configuration desired state assurance, but the specific unresolved condition here concerns terraform state lock and controlled backend for azure and has a different direct consequence.
D:Template duplication and hardcoded scopes can introduce policy drift or unintended resource replacement. That risk is relevant to bicep reusable modules with environment-specific parameters, but the specific unresolved condition here concerns terraform state lock and controlled backend for azure and has a different direct consequence.
Question 671
A deployment modifies a storage account configuration but operators execute ARM without reviewing unexpected deletions. What change should the DevOps engineer implement FIRST for the stated Azure DevOps requirement?
- Use Azure Resource Manager or Bicep what-if and scope-aware approvals to review intended resource changes.
- Define reusable Bicep modules with parameter files and explicit resource scopes and dependencies.
- Apply supported Azure Machine Configuration or desired-state controls with compliance monitoring and remediation procedures.
- Pin reusable IaC module versions and review changes using integration plans for all important consumers.
Explanation
Correct Answer
A:Use Azure Resource Manager or Bicep what-if and scope-aware approvals to review intended resource changes. Declarative infrastructure deployment can be syntactically valid while proposing harmful state transitions. Unreviewed IaC effects can interrupt services or delete data despite a green pipeline parse.
Incorrect Answers
B:Define reusable Bicep modules with parameter files and explicit resource scopes and dependencies.
C:Apply supported Azure Machine Configuration or desired-state controls with compliance monitoring and remediation procedures. That applies to azure machine configuration desired state assurance, not arm template what-if detecting unintended replacements.
D:Pin reusable IaC module versions and review changes using integration plans for all important consumers. That applies to versioned infrastructure modules and breaking upgrade control, not arm template what-if detecting unintended replacements.
Question 672
A deployment modifies a storage account configuration but operators execute ARM without reviewing unexpected deletions. What check would most directly verify this Microsoft DevOps control?
- Run deployment what-if and deploy to an isolated subscription to confirm idempotence and environment boundaries.
- Compare what-if changes and deployed resource IDs against approved design and verify protected assets survive.
- Run representative deployment plans for previous and candidate module versions and compare stateful resource effects.
- Attempt concurrent test operations and verify one waits for the lock while state history remains recoverable.
Explanation
Correct Answer
B:Compare what-if changes and deployed resource IDs against approved design and verify protected assets survive. Declarative infrastructure deployment can be syntactically valid while proposing harmful state transitions.
Incorrect Answers
A:Run deployment what-if and deploy to an isolated subscription to confirm idempotence and environment boundaries.
C:Run representative deployment plans for previous and candidate module versions and compare stateful resource effects. That applies to versioned infrastructure modules and breaking upgrade control, not arm template what-if detecting unintended replacements.
D:Attempt concurrent test operations and verify one waits for the lock while state history remains recoverable.
Question 673
A deployment modifies a storage account configuration but operators execute ARM without reviewing unexpected deletions. What is the underlying reason the existing approach fails?
- Declarative IaC must define intended state, scope, and dependencies rather than rely on mutable manual steps.
- Declarative infrastructure deployment can be syntactically valid while proposing harmful state transitions.
- Governed self-service can speed delivery only when available templates and permissions preserve the enterprise baseline.
- Terraform state represents actual managed resources and needs concurrency and confidentiality controls.
Explanation
Correct Answer
B:Declarative infrastructure deployment can be syntactically valid while proposing harmful state transitions. Unreviewed IaC effects can interrupt services or delete data despite a green pipeline parse.
Incorrect Answers
A:Declarative IaC must define intended state, scope, and dependencies rather than rely on mutable manual steps. That applies to bicep reusable modules with environment-specific parameters, not controlling principle for arm template what-if detecting unintended replacements.
C:Governed self-service can speed delivery only when available templates and permissions preserve the enterprise baseline. That applies to azure deployment environments for governed self-service, not controlling principle for arm template what-if detecting unintended replacements.
D:Terraform state represents actual managed resources and needs concurrency and confidentiality controls. That applies to terraform state lock and controlled backend for azure, not controlling principle for arm template what-if detecting unintended replacements.
Question 674
A deployment modifies a storage account configuration but operators execute ARM without reviewing unexpected deletions. Which recurring control most directly sustains the required behavior?
- Review policy versions and exemption expiry after organizational hierarchy or compliance changes.
- Version environment definitions and routinely clean up expired resources and exceptional permissions.
- Review module versioning and parameter validation for every supported environment.
- Require additional approval for stateful resource replacement and environment scope changes.
Explanation
Correct Answer
D:Require additional approval for stateful resource replacement and environment scope changes. Unreviewed IaC effects can interrupt services or delete data despite a green pipeline parse.
Incorrect Answers
A:Review policy versions and exemption expiry after organizational hierarchy or compliance changes. This helps sustain a control for azure policy-as-code guardrails in deployment pipelines; it does not directly stop recurrence of arm template what-if detecting unintended replacements described in this case.
B:Version environment definitions and routinely clean up expired resources and exceptional permissions. This helps sustain a control for azure deployment environments for governed self-service; it does not directly stop recurrence of arm template what-if detecting unintended replacements described in this case.
C:Review module versioning and parameter validation for every supported environment.
Question 675
A deployment modifies a storage account configuration but operators execute ARM without reviewing unexpected deletions. What is the MOST important consequence if this issue remains unresolved?
- Configuration drift can disable monitoring or create inconsistent vulnerability exposure across servers.
- Template duplication and hardcoded scopes can introduce policy drift or unintended resource replacement.
- Unreviewed IaC effects can interrupt services or delete data despite a green pipeline parse.
- State corruption can trigger destructive infrastructure changes or leak sensitive attributes.
Explanation
Correct Answer
C:Unreviewed IaC effects can interrupt services or delete data despite a green pipeline parse. This is the directly relevant business or security consequence of arm template what-if detecting unintended replacements. Root cause: Declarative infrastructure deployment can be syntactically valid while proposing harmful state transitions.
