The correct combination is to enable 'Secure transfer required', configure a key rotation policy, and set 'Public network access' to 'Disabled'. This trio works together because 'Secure transfer required' enforces HTTPS for all data in transit, ensuring encryption is never bypassed; the key rotation policy automates the regeneration of access keys every 90 days, meeting the compliance requirement without manual intervention; and disabling public network access effectively blocks all traffic from public IP addresses by default, restricting connectivity to only trusted virtual networks. On the AZ-500 exam, this scenario tests your understanding of layered storage security controls, often appearing as a multi-step configuration question where candidates mistakenly choose a single setting like a firewall rule alone, forgetting that firewalls do not enforce HTTPS encryption. A common trap is assuming disabling anonymous access or setting network rules alone covers encryption, but only 'Secure transfer required' addresses the HTTPS mandate. Memory tip: think "HTTPS, Keys, Network" as three separate levers—encryption, rotation, and isolation—each solving one distinct requirement.
AZ-500 Secure compute, storage, and databases Practice Question
This AZ-500 practice question tests your understanding of secure compute, storage, and databases. 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.
Your organization uses Azure Storage to host sensitive financial data. You need to ensure that all access to the storage account is encrypted in transit and that access keys are rotated automatically every 90 days. You also need to prevent access from public IP addresses. Which combination of configurations 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
✓
Enable 'Secure transfer required', configure key rotation policy, and set 'Public network access' to 'Disabled'
Option B is correct because enabling 'Secure transfer required' enforces HTTPS, automatic key rotation can be configured in the storage account settings, and the 'Selected networks' firewall with a deny-all default rule blocks public IPs. Option A is wrong because disabling public network access alone does not enforce HTTPS. Option C is wrong because firewall rules do not enforce HTTPS. Option D is wrong because disabling anonymous access does not enforce HTTPS.
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.
✗
Configure a network firewall rule to block all traffic, enable 'Secure transfer required', and rotate keys manually every 90 days
Why it's wrong here
Manual rotation is not automatic.
✗
Enable 'Allow trusted Microsoft services', configure key rotation policy, and disable 'Allow storage account key access'
Why it's wrong here
Allowing trusted services does not enforce HTTPS or block public IPs.
✗
Enable 'Secure transfer required', configure key rotation policy, and disable 'Allow Blob public access'
Why it's wrong here
Disabling blob public access does not enforce HTTPS or rotate keys.
✓
Enable 'Secure transfer required', configure key rotation policy, and set 'Public network access' to 'Disabled'
Why this is correct
This enforces HTTPS, rotates keys, and blocks public access.
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.
