A company uses Azure DevOps to deploy a web app. The deployment pipeline must automatically roll back to the previous version if the new version fails health checks after deployment. The team also wants to minimize downtime during the deployment. Which deployment strategy should you recommend?

Recreate deployment by stopping the old version and starting the new one.

Canary deployment with incremental traffic shifting.

Rolling deployment with manual rollback.

Blue-green deployment with automated health checks and swap back to the previous slot.

A company is deploying a microservices application to Azure Kubernetes Service (AKS). The application has feature flags and configuration settings that change frequently and must be updated without redeploying the containers. The configuration also includes connection strings that must be stored securely. You need to recommend a configuration management solution. What should you do?

Use Azure App Configuration for feature flags and non-secret settings, and Azure Key Vault for connection strings.

Embed configuration in the container image at build time.

Use Kubernetes ConfigMaps and Secrets.

Store all configuration in Azure Key Vault, including feature flags.

Which statement best describes a core principle of event-driven architecture?

Consumers must be online at the exact moment an event is produced to receive it.

Producers and consumers are tightly coupled through direct API calls.

Producers emit events without knowing which consumers will react to them.

Events are always processed synchronously to ensure immediate consistency.

A web application reads a product catalog from a relational database. The catalog changes infrequently but is read frequently. The current architecture causes high database load and slow response times during peak hours. You need to reduce database load and improve response times without changing the application's code to use a different data access pattern. What should you recommend?

Scale the database to a higher performance tier.

Use Azure Content Delivery Network (CDN) to cache the catalog API responses.

Use Azure SQL Database read replicas.

Implement Azure Cache for Redis and cache the catalog data with a short expiration.
