The correct answer is that the template does not configure network rules, so the container may be accessible from the internet, but only to authenticated users. This is because while the template sets the container’s publicAccess property to None—effectively blocking anonymous access—it fails to define any network rules for the storage account. Without explicit firewall or virtual network restrictions, the container inherits the storage account’s default network configuration, which allows access from any internet source as long as the request includes valid Azure AD or shared key credentials. On the Microsoft Cybersecurity Architect exam, this scenario tests your understanding of the layered security model: public access controls and network rules are independent settings, and both must be locked down to prevent unauthorized exposure. A common trap is assuming that setting publicAccess to None alone secures the container, but it only prevents anonymous browsing—authenticated users from anywhere can still connect. Memory tip: think of it as two doors—publicAccess locks the front door for strangers, but network rules are the fence that keeps out everyone, even guests with keys.
SC-100 Practice Question: Design security solutions for applications and data
This SC-100 practice question tests your understanding of design security solutions for applications and data. 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.
Refer to the exhibit. A security architect is reviewing an ARM template that deploys an Azure Storage container. They want to ensure the container is not publicly accessible. What is the security implication of this template?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The template does not configure network rules, so the container may be accessible from the internet, but only to authenticated users
The template sets 'publicAccess' to 'None', which means no anonymous access. However, the container inherits default network rules from the storage account. If the storage account firewall is not configured, the container may still be accessible over the internet by authenticated users. Option C is correct. Option A is wrong because public access is set to None. Option B is wrong because network rules are not defined in this template. Option D is wrong because the template does not mention encryption.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The container allows public access
Why it's wrong here
The template sets publicAccess to None, so no public access.
✗
The template creates a container with versioning enabled
Why it's wrong here
Versioning is not configured.
✗
The template enables encryption at rest
Why it's wrong here
Encryption is not configured in this snippet.
✓
The template does not configure network rules, so the container may be accessible from the internet, but only to authenticated users
Why this is correct
Without network restrictions, authenticated users from anywhere can access the container.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
