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. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 are designing a data processing solution in Azure Databricks that uses Unity Catalog. The security team requires that all users authenticate using Microsoft Entra ID and that access to tables is governed by attribute-based access control (ABAC) using table tags. Which feature should you enable?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Table tags with access control lists (ACLs) in Unity Catalog.
Option B is correct because Unity Catalog supports ABAC through tags and Azure Databricks can use Microsoft Entra ID for authentication. Option A is wrong because row-level security is for filtering rows, not ABAC with tags. Option C is wrong because column-level security is for columns. Option D is wrong because dynamic views are for custom logic, not attribute-based access control with tags.
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.
✗
Column-level security masks.
Why it's wrong here
Column-level security masks columns but does not use tags for ABAC.
✗
Dynamic views with user context functions.
Why it's wrong here
Dynamic views can restrict access but are not specifically designed for tag-based ABAC.
✗
Row-level security filters.
Why it's wrong here
Row-level security filters rows based on user identity, but does not use table tags for ABAC.
✓
Table tags with access control lists (ACLs) in Unity Catalog.
Why this is correct
Unity Catalog supports ABAC using tags and ACLs, and integrates with Microsoft Entra ID for authentication.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
