Microsoft DevOps Engineer Expert AZ-400 Practice Question

Your company uses Azure DevOps Services. Security policy requires that all build jobs run inside a private subnet that blocks direct outbound internet traffic but allows traffic through an authenticated HTTP proxy. The build workload needs Docker-in-Docker support and must automatically scale to roughly 20 parallel jobs during peak hours while keeping VM administration effort and compute cost as low as possible. Which solution should you recommend?

  • Use Microsoft-hosted agents and attach a private endpoint to the subnet to run builds behind the firewall.

  • Ask each developer to install a self-hosted agent on their workstation and add the machines to a shared agent pool for burst capacity.

  • Deploy a self-hosted agent pool backed by an Azure Virtual Machine Scale Set in the private subnet, configure the scale set with the Azure DevOps VMSS agent extension, and set the agents to use the corporate HTTP proxy.

  • Provision 20 dedicated virtual machines in the subnet, install the self-hosted agent manually on each VM, and disable any automatic scaling features.
