Question 411
The customer states: A regional office requires local Windows Server file cache for low-latency access while retaining a central cloud file share. An incident reveals: Remote branch users see slow direct cloud-share access and no local cached file namespace. What cause best accounts for this evidence?
- A cloud file share alone did not meet the local caching and synchronization requirement.
- The block storage service tier is undersized for the measured IO profile.
- Object/blob storage was mistaken for a managed high-throughput POSIX shared filesystem.
- Blob object APIs do not expose the SMB file-share semantics needed by the legacy application.
Explanation
Correct Answer
A:The incident is explained by: A cloud file share alone did not meet the local caching and synchronization requirement. The reported symptom is: Remote branch users see slow direct cloud-share access and no local cached file namespace. The corresponding design fix is: Deploy Azure File Sync with a cloud endpoint and registered Windows Server endpoints using compatible tiering.
Incorrect Answers
B:The proposed diagnosis fits another scenario: The block storage service tier is undersized for the measured IO profile. It would typically be reflected by: Random writes are throttled by a low-performance managed disk type. The current evidence instead supports: A cloud file share alone did not meet the local caching and synchronization requirement.
C:The alternative weakness is: Object/blob storage was mistaken for a managed high-throughput POSIX shared filesystem. Its associated failure is: Standard object requests cannot satisfy POSIX filesystem and low-latency shared file requirements. Neither explains the present observation: Remote branch users see slow direct cloud-share access and no local cached file namespace. The direct cause here is: A cloud file share alone did not meet the local caching and synchronization requirement.
D:This cause would explain a different symptom: The application cannot open object URLs through its normal Windows file path APIs. The mechanism for that event is: Blob object APIs do not expose the SMB file-share semantics needed by the legacy application. Here the stated symptom is: Remote branch users see slow direct cloud-share access and no local cached file namespace. Its cause is: A cloud file share alone did not meet the local caching and synchronization requirement.
