DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
You have an Azure Databricks workspace that uses a managed resource group. The security team requires that all cluster nodes use no public IP addresses and that all outbound traffic goes through a firewall. What should you configure?
⚠ Common exam trap
DP-203 often tests the difference between Private Link (private access to the workspace) and VNet injection with forced tunneling (control over cluster egress), so candidates who pick Private Link miss the 'no public IP on nodes' and 'all outbound through firewall' requirements.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Deploy the workspace in a VNet with forced tunneling enabled and a firewall.
To ensure no public IPs on cluster nodes and all outbound traffic routed through a firewall, you must deploy the Azure Databricks workspace into your own VNet (VNet injection) with forced tunneling enabled, and route egress through a firewall such as Azure Firewall or a user-defined route to an NVA. VNet injection gives you control over the subnets, NSGs, and routing, and forced tunneling redirects all outbound traffic to your inspection appliance. This is the documented architecture for secure, no-public-IP Databricks deployments.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure service endpoints for Azure Storage and Azure Data Lake Storage.
Why it's wrong here
Service endpoints give the subnet private routes to specific PaaS services, but cluster nodes still receive public IPs and general outbound traffic bypasses any firewall. They suit locking storage access to a subnet, not the no-public-IP plus forced-tunnelling requirement here.
- ✓
Deploy the workspace in a VNet with forced tunneling enabled and a firewall.
Why this is correct
Deploying into a customer-managed VNet with forced tunnelling routes all cluster node egress through your firewall appliance, satisfying the outbound inspection requirement. Secure cluster connectivity (no public IP) is enabled alongside, so nodes hold no public addresses. This meets both constraints the security team specified.
- ✗
Apply network security groups (NSGs) to the subnet that restrict outbound traffic.
Why it's wrong here
NSGs filter traffic by rules but cannot remove public IP addresses from cluster nodes, nor do they route outbound traffic through a firewall appliance. They are the right tool for controlling allowed ports and sources on a subnet, not for this isolation requirement.
- ✗
Enable Azure Private Link for the Databricks workspace.
Why it's wrong here
Private Link provides private endpoint access to the workspace control plane, yet cluster nodes still obtain public IPs and outbound traffic is not forced through a firewall. It fits restricting inbound access to the workspace over a private endpoint, not this scenario.
