Worked practice questions

Which infrastructure-as-code (IaC) tool is widely adopted across all major clouds for declarative resource provisioning?

  1. tar
  2. Microsoft Word
  3. rsync
  4. Terraform
Show answer and solution

Correct answer: D. Terraform

Terraform is the multi-cloud IaC standard with providers for AWS, Azure, GCP, and many SaaS APIs. The others are document editors, file-sync, and archive tools.

Which IaC concept describes ensuring that applying the same configuration twice yields the same result without unintended side effects?

  1. Idempotency
  2. Polymorphism
  3. Backpressure
  4. Eventual consistency
Show answer and solution

Correct answer: A. Idempotency

Idempotent operations can be reapplied safely. Eventual consistency, polymorphism, and backpressure are distributed-systems / OOP / streaming concepts — not IaC's apply-twice property.

Which open-source standard defines vendor-neutral APIs and SDKs for emitting metrics, logs, and traces from applications?

  1. Markdown
  2. JSON Schema
  3. OpenTelemetry
  4. OAuth 2.0
Show answer and solution

Correct answer: C. OpenTelemetry

OpenTelemetry (OTel) is the CNCF standard for instrumentation across all three signal types. JSON Schema describes data shapes, OAuth handles authorization, Markdown is for documentation.
