The correct answer is that low latency between session hosts and storage, support for SMB protocol, and high IOPS are the three key considerations when designing FSLogix profile storage for Azure Virtual Desktop. FSLogix profiles mount VHDX files from a remote share, so any network delay directly degrades the user login experience and application responsiveness, making low latency non-negotiable. Azure Files with SMB 3.0 is the only supported share type, and high IOPS are essential because each user’s profile read and write operations—especially during sign-in and app launches—must complete quickly to avoid bottlenecks. On the AZ-305 exam, this question tests your ability to differentiate between performance-critical storage requirements and common distractors like public endpoints or geo-redundancy, which are not needed for FSLogix. A common trap is assuming redundancy is mandatory, but locally redundant or zone-redundant storage is sufficient since profiles are ephemeral and can be rebuilt. Memory tip: think “L-S-H” for Latency, SMB, High IOPS—the three pillars of a fast AVD profile experience.
AZ-305 Design data storage solutions Practice Question
This AZ-305 practice question tests your understanding of design data storage solutions. 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.
Which THREE considerations are important when designing a storage solution for Azure Virtual Desktop (AVD) user profiles using FSLogix? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Azure Files as the storage solution.
Options B, C, and D are correct. FSLogix profiles require a share that supports SMB (Azure Files). Low latency is critical for user experience. High IOPS are needed for profile reads/writes. Option A is wrong because public endpoint is not required; private endpoint is recommended. Option E is wrong because geo-redundancy is not typically required for FSLogix; locally redundant or zone-redundant is sufficient.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
Use Azure Files as the storage solution.
Why this is correct
Supports SMB, needed for FSLogix.

✗
Use a public endpoint for profile storage.
Why it's wrong here
Private endpoint is recommended for security.
✓
Provision sufficient IOPS for user profiles.
Why this is correct
High IOPS needed for profile operations.

✗
Enable geo-redundant storage (GRS) for disaster recovery.
Why it's wrong here
Not typically required; LRS or ZRS is sufficient.
✓
Ensure low latency between session hosts and storage.
Why this is correct
Critical for user experience.

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.
