Designing Microsoft Azure Infrastructure Solutions (AZ-305) — All Questions

A team is building a microservices application and wants managed Kubernetes orchestration with autoscaling and rolling updates. Which compute platform should the architect choose?
- a.A single large virtual machine
- b.Azure Functions consumption plan
- c.Azure Kubernetes Service (AKS)✓
- d.Azure Blob storage
AKS provides managed Kubernetes with autoscaling, rolling updates, and integration with Azure identity and networking, fitting orchestrated microservices. A single VM lacks orchestration, Functions targets event-driven code rather than full microservice orchestration, and Blob storage is not compute.
An architect wants to decouple an order-processing system so components communicate reliably with ordering and transactional messaging. Which service fits best?
- a.Azure Service Bus✓
- b.Azure Blob storage
- c.Azure DNS
- d.Azure Bastion
Azure Service Bus is an enterprise message broker supporting queues, topics, ordering (sessions), and transactions, ideal for decoupling reliable business processes. Blob storage stores objects, DNS resolves names, and Bastion provides secure VM access.
A web application on Azure App Service must be released with zero downtime and the ability to quickly roll back. Which feature should the architect use?
- a.Editing files directly on the production instance
- b.A single production slot only
- c.Scaling up the plan during deployment
- d.Deployment slots with slot swap✓
Deployment slots let you deploy and warm up a new version in a staging slot, then swap it into production instantly with the ability to swap back, achieving zero-downtime releases and fast rollback. Editing production directly, using one slot, or scaling up does not provide safe swap-based releases.
An architect needs high-throughput ingestion of millions of telemetry events per second for streaming analytics. Which service is designed for this?
- a.Azure Service Bus queues
- b.Azure Event Hubs✓
- c.Azure Files
- d.Azure SQL Database
Azure Event Hubs is built for high-throughput event streaming and ingestion at massive scale, feeding analytics pipelines. Service Bus targets enterprise messaging at lower throughput with richer semantics, Files is a file share, and SQL Database is relational storage.
