You want to deploy an Azure Function App that must scale automatically based on demand and you want to minimize costs when idle. Which hosting plan should you choose?
Think about a plan that charges only when your function runs and can scale automatically.
The Consumption Plan automatically scales based on demand and charges only for actual executions, minimizing cost when idle. Other plans either have fixed costs or require manual scaling.
You want to securely store a database connection string for your Azure Function App. Where should you store this value to follow best practices?
Consider where Azure recommends storing secrets and configuration values for apps.
Application Settings in the Azure Portal are encrypted and injected as environment variables at runtime, which is the recommended way to store secrets like connection strings.
You notice your Azure Function App takes longer to respond after being idle for some time. What causes this delay?
Think about what happens when a function app is not running and a new request arrives.
In the Consumption Plan, when the function app is idle, it scales down to zero instances. The first request after idle triggers a cold start, causing delay.
You want to restrict access to your HTTP-triggered Azure Function App so only authorized clients can call it. Which method provides the best security?
Consider a method that integrates with identity providers for secure access.
Azure Active Directory authentication provides strong identity-based access control, better than sharing keys or IP filtering.
You want to deploy a new version of your Azure Function App without downtime and be able to quickly roll back if needed. What is the best deployment strategy?
Think about how to deploy safely with minimal impact on users.
Deployment slots allow you to deploy and test a new version in a staging environment, then swap it with production instantly, enabling zero downtime and easy rollback.
