- A
Configure service endpoints for Azure Storage and Azure Data Lake Storage.
Why wrong: Service endpoints provide private connectivity to PaaS services but do not remove public IPs from cluster nodes.
- B
Deploy the workspace in a VNet with forced tunneling enabled and a firewall.
VNet injection with forced tunneling ensures cluster nodes have no public IPs and all outbound traffic goes through the firewall.
- C
Apply network security groups (NSGs) to the subnet that restrict outbound traffic.
Why wrong: NSGs can filter traffic but do not route all traffic through a firewall; they are not a substitute for forced tunneling.
- D
Enable Azure Private Link for the Databricks workspace.
Why wrong: Private Link secures access to the workspace but does not control cluster node public IPs.
Quick Answer
The correct answer is to deploy the workspace in a VNet with forced tunneling enabled and a firewall. This configuration ensures Azure Databricks cluster nodes have no public IP addresses and that all outbound traffic is routed through a firewall, meeting the security team’s requirements for a locked-down, inspectable network path. On the Microsoft Azure Data Engineer Associate DP-203 exam, this scenario tests your understanding of VNet injection and forced tunneling for Databricks, often appearing as a trap where candidates confuse private endpoints (which secure data plane access, not cluster nodes) or service endpoints (which don’t eliminate public IPs). A common mistake is thinking network security groups alone can force traffic through a firewall, but they only filter traffic, not route it. Remember the mnemonic: “No IP, forced trip” — for no public IPs, you must force all traffic through the firewall via forced tunneling.
DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
This DP-203 practice question tests your understanding of secure, monitor, and optimize data storage and data processing. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
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.
Option D is correct because Azure Databricks can be deployed in a VNet injected configuration with no public IPs and route all traffic through a firewall. Option A is wrong because private endpoints are for data plane services, not for cluster nodes. Option B is wrong because service endpoints do not eliminate public IPs. Option C is wrong because network security groups control inbound/outbound rules but do not force traffic through a firewall.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
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.
- ✓
Deploy the workspace in a VNet with forced tunneling enabled and a firewall.
- ✗
Apply network security groups (NSGs) to the subnet that restrict outbound traffic.
Why it's wrong here
NSGs can filter traffic but do not route all traffic through a firewall; they are not a substitute for forced tunneling.
- ✗
Enable Azure Private Link for the Databricks workspace.
Why it's wrong here
Private Link secures access to the workspace but does not control cluster node public IPs.
Common exam traps
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
What to study next
Got this wrong? Here's your next step.
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related DP-203 subnetting questions on CIDR, address ranges, and subnet selection.
