The correct answer is to configure firewall rules to restrict access to specific IP addresses or VNets and to use managed identities for authentication. These two practices are recommended Azure Storage security best practices because they directly reduce the attack surface and eliminate the need to store credentials in code or configuration files. Firewall rules ensure that only trusted network sources can reach your storage account, while managed identities allow Azure resources to authenticate without exposing secrets, aligning with the principle of least privilege. On the Microsoft Azure Developer Associate AZ-204 exam, this topic tests your understanding of securing sensitive data in Azure Storage, often appearing as a scenario where you must choose between SAS tokens, access keys, and network controls. A common trap is selecting long-lived SAS tokens or frequent key rotation as primary solutions—remember that network isolation and identity-based access are foundational. Memory tip: “Firewall the flow, identity the access.”
AZ-204 Implement Azure security Practice Question
This AZ-204 practice question tests your understanding of implement azure security. 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 secure access to an Azure Storage account that contains sensitive data. Which TWO of the following are recommended best practices?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use managed identities to access storage from Azure services
Option B is correct because limiting network access reduces attack surface. Option C is correct because using managed identities avoids storing credentials. Option A is wrong because SAS tokens with long expiry increase risk. Option D is wrong because public access should be disabled except for specific containers when needed. Option E is wrong because storage account keys should be rotated regularly, but not necessarily every 24 hours.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
✗
Rotate storage account keys every 24 hours
Why it's wrong here
Frequent rotation is burdensome; 90-180 days is typical.
✓
Use managed identities to access storage from Azure services
Why this is correct
Managed identities avoid storing credentials.

✗
Use SAS tokens with long expiry dates
Why it's wrong here
Long expiry increases risk if token is leaked.

Enable anonymous public access for all containers
Why it's wrong here
Public access should be disabled by default.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
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.
