The correct answer is to configure a session policy in Microsoft Defender for Cloud Apps to block clipboard and screenshot actions. This works because Defender for Cloud Apps acts as a reverse proxy, inspecting and controlling user sessions in real time, which allows it to prevent data exfiltration from Azure SQL Database by intercepting clipboard copies and screenshot attempts directly within the browser. On the Microsoft Cybersecurity Architect exam, this scenario tests your understanding of how session policies enforce granular data protection beyond native database controls—a common trap is confusing logging (auditing) or masking (Dynamic Data Masking) with active prevention. Remember, Defender for Cloud Apps session policies are the only option here that proactively blocks exfiltration actions rather than merely detecting or obfuscating them. A useful memory tip: think of the session policy as a security guard standing between the user and the data, not just a camera watching the door.
SC-100 Design security solutions for infrastructure Practice Question
This SC-100 practice question tests your understanding of design security solutions for infrastructure. 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.
Your organization uses Azure SQL Database and needs to protect sensitive data from being exported by unauthorized users. You must implement a solution that prevents users from copying data to clipboard or taking screenshots of query results, while allowing legitimate business operations. What should you implement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure a session policy in Microsoft Defender for Cloud Apps to block clipboard and screenshot actions.
Option C is correct because Microsoft Defender for Cloud Apps session policies can monitor and control data exfiltration via reverse proxy, including blocking clipboard and screenshot actions. Option A is incorrect because Azure SQL Database Auditing logs activities but does not prevent them. Option B is incorrect because Dynamic Data Masking obfuscates data but does not prevent export. Option D is incorrect because Azure Information Protection labels files but does not prevent clipboard actions in a browser.
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.
✗
Apply Azure Information Protection labels to the database.
Why it's wrong here
Labels are for classification, not prevention.
✗
Use Dynamic Data Masking to obscure sensitive columns.
Why it's wrong here
Masking does not prevent export.
✗
Enable Azure SQL Database Auditing and threat detection.
Why it's wrong here
Auditing is detective, not preventive.
✓
Configure a session policy in Microsoft Defender for Cloud Apps to block clipboard and screenshot actions.
Why this is correct
Session policies can control data exfiltration in real-time.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
