Recall & Review

beginner

What is an Azure Container App?

An Azure Container App is a service that lets you run containerized applications without managing servers. It automatically handles scaling and networking for your app.

How do Container Apps help with microservices?

Container Apps let you run each microservice in its own container. They can scale independently and communicate securely, making it easier to build and manage microservices.

What is the role of Dapr in Azure Container Apps?

Dapr is a set of building blocks for microservices that helps with service discovery, state management, and messaging inside Container Apps, simplifying microservice communication.

intermediate

Why is automatic scaling important for microservices in Container Apps?

Automatic scaling adjusts the number of container instances based on demand. This keeps your microservices responsive and cost-efficient by using resources only when needed.

intermediate

What networking feature allows microservices in Container Apps to communicate securely?

Container Apps use private networking and service-to-service authentication to ensure microservices communicate securely without exposing them to the public internet.

What does Azure Container Apps primarily manage for you?

A Server infrastructure and scaling

B Writing application code

C Database management

D Manual container deployment

Azure Container Apps automatically manage server infrastructure and scaling so you can focus on your app.

Which technology helps microservices communicate inside Azure Container Apps?

A Azure Blob Storage

B SQL Server

C Dapr

D Azure Functions

Dapr provides building blocks for service communication inside Container Apps.

How do Container Apps handle scaling for microservices?

A Manually by the user

B Automatically based on traffic

C Scaling is not supported

D Only scale at fixed times

Container Apps automatically scale microservices based on demand.

What is a benefit of running microservices in separate containers?

A They can scale independently

B They cannot communicate

C They must run on the same server

D They share the same codebase

Running microservices in separate containers allows each to scale independently.

Which feature helps secure communication between microservices in Container Apps?

A Public IP addresses

B Unencrypted traffic

C Open ports

D Service-to-service authentication

Service-to-service authentication ensures secure communication between microservices.
