Exam AZ-303: Microsoft Azure Architect Technologies Practice Test
AZ-303 practice addresses Azure architecture and implementation decisions across compute, networking, storage, databases, identity, and application monitoring. The available questions use scenarios involving fixed outbound IP addresses, managed container hosting, globally distributed data, secure resource changes, and application telemetry. They focus on selecting and configuring Azure services to meet operational and security needs.
Exam overview
About the Exam AZ-303: Microsoft Azure Architect Technologies Exam
Architects working with Azure must match service capabilities to workload requirements, then account for availability, security, performance, and operational effort. Relevant decisions include routing outbound traffic through a stable public IP, choosing managed compute for containers or timer-triggered scripts, and selecting a database based on distribution, latency, data model, and consistency. Network health probes affect whether a load balancer continues directing traffic to an instance. Identity and deployment practices also matter: managed identities can avoid embedded storage credentials, while approval controls can reduce unauthorized changes. Infrastructure-as-code workflows may use reusable Bicep modules, and private container registries support consistent image distribution. Application Insights-style telemetry helps teams investigate exceptions, failed requests, and dependency performance. Practice scenarios can help build service-selection judgment and clarify how design choices address specific constraints.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A service running in Azure must send outbound Internet traffic through a fixed public IP address so a partner can allowlist it. Which option is a suitable design for a virtual machine subnet?
Show answer
Correct answer: AA NAT Gateway provides outbound connectivity for resources in an associated subnet and uses its configured public IP address or prefix for translated outbound traffic, giving the partner a stable address to allowlist.
An Azure application must run a containerized web service without requiring the team to manage virtual machines or a Kubernetes control plane. Which service is a suitable option?
Show answer
Correct answer: AAzure Container Instances can run containers without requiring the customer to provision or administer virtual machines or a Kubernetes cluster.
An Azure solution must provide a globally distributed, multi-model database with low-latency reads and a choice of consistency levels. Which service is the most suitable fit?
Show answer
Correct answer: AAzure Cosmos DB is a globally distributed database service that supports multiple data models and APIs, along with configurable consistency levels and replication options.
An organization wants to reduce the risk that a compromised administrator account can make unauthorized changes to sensitive Azure resources. Which practice adds a requirement for an approved change before deployment?
Show answer
Correct answer: CAzure Policy can audit or deny resource configurations that do not comply with defined rules. A deny policy can block noncompliant changes, although policy is not a substitute for identity protection or carefully scoped access controls.
A web application runs on multiple Azure virtual machines behind an Azure Load Balancer. Which health probe behavior helps the load balancer stop sending new traffic to an unhealthy instance?
Show answer
Correct answer: AAzure Load Balancer health probes determine whether backend instances are available to receive new flows. Instances that fail the configured probe criteria are taken out of rotation until they become healthy again.
An architect needs a central place to store, version, and securely share reusable infrastructure deployment modules across teams. Which Azure service is intended for storing and distributing Bicep modules?
Show answer
Correct answer: AAzure Container Registry can host Bicep modules in a registry, allowing teams to version and reuse modules through registry references. Azure Artifacts is primarily for package feeds, while the other services serve different purposes.
A team wants to deploy an application image consistently across environments and needs a managed private registry for storing and distributing container images. Which Azure service is appropriate?
Show answer
Correct answer: AAzure Container Registry is a managed registry for storing and distributing container images, including private images used by deployment pipelines and Azure container services. Container Instances runs containers rather than serving as their image registry.
How to use this practice test
The free US Practice Tests bank contains 50 published questions. A practice session presents up to 20 random questions and shows results afterward. Use each scenario to explain why a service or configuration fits the stated requirement, then revisit missed items by comparing the relevant Azure capabilities and tradeoffs.
Preparation tips
- For fixed outbound IP scenarios, compare subnet-level routing options and trace how outbound traffic reaches the Internet.
- Distinguish managed container hosting from virtual-machine and Kubernetes-based approaches by identifying which infrastructure the team must operate.
- For distributed database scenarios, relate multi-model support, read latency, and consistency choices to application requirements.
- Trace how managed identities provide access to Storage without secrets in configuration, and how approval controls constrain sensitive deployments.
- Review the role of load-balancer health probes, private image registries, reusable Bicep modules, and application performance telemetry in operational designs.
