Architecting Microsoft Azure Solutions Free Practice Test — 30 Questions

Question 1

A critical real-time analytics solution deployed on Azure, processing high-volume telemetry from a fleet of industrial sensors, is exhibiting severe performance degradation. Users report significant delays in data availability on their dashboards, and intermittent failures in the alerting system. The architecture leverages Azure Event Hubs for data ingestion and Azure Stream Analytics for real-time transformation and analysis before data is persisted. Initial diagnostics indicate that the Event Hubs are experiencing increased latency, and Stream Analytics jobs are showing a growing backlog of unprocessed events. The solution was architected for high throughput and low latency, but current operational metrics suggest a fundamental mismatch between provisioned capacity and actual data load. Which of the following actions is the most critical first step to address this immediate operational crisis and restore system stability?

Accepted Answer

Increase the throughput units (TUs) for Azure Event Hubs and the streaming units (SUs) for the Azure Stream Analytics job.

Question 2

A multinational financial services firm is undertaking a significant modernization initiative to transform its legacy on-premises trading platform into a cloud-native, microservices-based solution on Azure. The existing application is a tightly coupled monolith that manages real-time market data, order execution, and client portfolio updates, with strict requirements for data consistency, low latency, and compliance with regulations such as GDPR and SOX. The firm needs to decompose this monolith into independent services, each responsible for a specific business capability, such as order management, market data ingestion, or user authentication. A critical challenge is ensuring that state changes are propagated reliably and efficiently between these new services, and that the overall system maintains transactional integrity despite the distributed nature of the architecture. Which combination of Azure services would best facilitate this transition by providing robust messaging for inter-service communication and a suitable data store for managing distributed state with varying consistency needs?

Accepted Answer

Azure Service Bus for messaging and Azure Cosmos DB for data storage

Question 3

A team architect is leading the development of a critical Azure-based data analytics platform. Midway through the project, a significant regulatory update mandates a complete re-architecture of the data ingestion and processing pipelines to comply with stricter data residency and anonymization requirements.
