AZ-500 Secure compute, storage, and databases Practice Question
This AZ-500 practice question tests your understanding of secure compute, storage, and databases. 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 need to prevent data exfiltration from Azure Storage accounts by controlling which networks can access them. Which Azure feature should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Storage firewalls and virtual network rules
Azure Storage firewalls and virtual network rules allow you to restrict access to specific IP addresses or virtual networks. Option B is correct. Option A is wrong because SAS tokens provide time-limited access but do not restrict networks. Option C is wrong because Azure Private Link provides private connectivity but does not block exfiltration by itself. Option D is wrong because Azure Firewall is for network traffic filtering, not storage access control.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Azure Storage shared access signatures (SAS)
Why it's wrong here
SAS tokens grant access but do not restrict network origins.
✗
Azure Firewall
Why it's wrong here
Azure Firewall is for network traffic filtering, not directly for storage access.
✗
Azure Private Link
Why it's wrong here
Private Link provides private connectivity but does not block exfiltration via other paths.
✓
Azure Storage firewalls and virtual network rules
Why this is correct
These rules restrict access to specific networks, preventing exfiltration.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
