These tiers determine what functionalities are available, including ACR Tasks and Private Link (Private Endpoints) integration.

Analysis:

ACR Tasks:

ACR Tasks allow you to automate image builds and updates when base images or application code changes.

Supported in Standard and Premium tiers (as per Microsoft Docs: “ACR Tasks are available in Standard and Premium service tiers.”).

Therefore, ContReg1 (Premium) and ContReg2 (Standard) support ACR Tasks.

ContReg3 (Basic) does not support advanced tasks automation at scale.

✅ Answer: ContReg1 and ContReg2 only

Private Endpoints:

Private Link (Private Endpoints) enables private network connectivity to the ACR from a virtual network.

According to Azure documentation:

“Private Link for Azure Container Registry is supported only in the Premium service tier.”

This ensures that access to the registry occurs via Azure’s backbone, preventing exposure to the public internet.

✅ Answer: ContReg1 only (Premium)
