  1. Question 1Develop Azure compute solutions

    What is the difference between Azure Container Instances (ACI) and Azure Container Apps (ACA)?

    AThey are identical services
    BACI is for isolated, short-running containers (no autoscaling, basic networking); ACA is for microservices with autoscaling, revisions, Dapr, KEDA, and built-in ingress
    CACI is for Kubernetes workloads; ACA is for serverless functions
    DACA requires Docker Compose; ACI does not

  2. Question 2Develop Azure compute solutions

    A developer uses Azure Container Registry with geo-replication. What is the primary benefit of ACR geo-replication for Container Apps?

    AAutomatic container image vulnerability scanning
    BContainer images are served from the nearest replica region, reducing pull latency and cross-region data transfer costs
    CImages are automatically updated when the base image changes
    DRole-based access control is replicated across regions

AZ-204 Container Apps Exam Tips

Azure Container Apps & ACI questions in AZ-204 are typically scenario-based. Focus on Azure application development, integration services, authentication, and runtime reliability. Priority concepts: container apps, aci, container instances, acr, container registry, docker.

What AZ-204 Expects

  • Anchor your answer in choose managed developer services that simplify secure integration and deployment.
  • Container Apps scenarios for AZ-204 are frequently mapped to Domain 1 (25-30%), so read the objective carefully before picking controls or architecture.
  • Expect multi-topic scenarios where Container Apps interacts with identity, networking, governance, or monitoring patterns rather than appearing as an isolated question.
  • When two options are both technically valid, prefer the choice that best aligns with the exam's operational scope (Associate) and vendor best practices.

High-Value Container Apps Concepts

  • Know the core Container Apps building blocks cold: container apps, aci, container instances, acr.
  • Review the edge-case features and limits for container registry, docker; these details are commonly used to differentiate answer choices.
  • Practice service-integration reasoning: how Container Apps pairs with App Service, Azure Functions in real deployment patterns.
  • For AZ-204, explain why the chosen Container Apps design meets reliability, security, and cost expectations better than the alternatives.

Common AZ-204 Traps

  • Watch for using infrastructure-heavy answers for app-level requirements.
  • Questions in Develop Azure Compute Solutions often include distractors that look correct for Container Apps but violate least-privilege, compliance, or availability requirements.
  • Avoid picking options purely by feature name; validate data path, failure handling, and governance impact before answering.
  • If the prompt hints at automation or repeatability, eliminate manual-only operational answers first.

Fast Review Checklist

  • Can you compare at least two Container Apps implementation paths and justify which one best fits the scenario?
  • Can you map the chosen answer back to Develop Azure Compute Solutions (25-30%) outcomes for AZ-204?
  • Can you explain security and access boundaries for Container Apps without relying on default-open assumptions?
  • Can you describe how Container Apps integrates with App Service and Azure Functions during failure, scaling, and monitoring events?
