Recall & Review

beginner

What is Azure Container Registry (ACR)?

Azure Container Registry (ACR) is a private cloud service to store and manage container images securely, similar to a personal library for your app containers.

How does ACR help in application deployment?

ACR stores container images close to your Azure services, making app deployment faster and more reliable by pulling images from a nearby source.

Name one security feature of Azure Container Registry.

ACR supports Azure Active Directory authentication and role-based access control to keep your container images safe and accessible only to authorized users.

What is the benefit of geo-replication in ACR?

Geo-replication copies your container images to multiple Azure regions, so your apps can access images faster and stay available even if one region has issues.

What type of service is Azure Container Registry?

A A private container image storage service

B A virtual machine hosting service

C A database service

D A serverless compute service

Azure Container Registry is a private service to store container images securely.

Which authentication method does ACR support for secure access?

A Basic HTTP authentication

B FTP login

C Azure Active Directory

D Anonymous access

ACR uses Azure Active Directory for secure and managed access.

What is the main purpose of geo-replication in ACR?

A To convert images to virtual machines

B To reduce image size

C To encrypt container images

D To increase image availability across regions

Geo-replication copies images to multiple regions to improve availability and speed.

Which of these is NOT a benefit of using ACR?

A Automatic app code compilation

B Faster container image deployment

C Centralized container image management

D Secure storage of container images

ACR manages container images but does not compile app code automatically.

How does ACR improve deployment speed?

A By compressing images on the fly

B By storing images close to Azure services

C By running containers directly

D By converting images to scripts

Storing images near Azure services reduces download time during deployment.

Explain what Azure Container Registry is and why it is useful.

Think about how you keep your app containers ready and safe.

Describe how geo-replication in ACR benefits application availability and performance.

Imagine having backup copies of your app's containers in different places.
