AZ-104 Question #258: Real Exam Question with Answer & Explanation

Question

Hotspot Question You have a sync group named Sync1 that has a cloud endpoint. The cloud endpoint includes a file named File1.txt. Your on-premises network contains servers that run Windows Server 2016. The servers are configured as shown in the following table. You add Share1 as an endpoint for Sync1. One hour later, you add Share2 as an endpoint for Sync1. For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point. Answer:

Options

• __typehotspot
• variantyes_no

Explanation

Azure File Sync handles file conflicts by preserving both versions rather than overwriting them, and all synced files will replicate to other endpoints in the sync group.

Approach. When a server endpoint is added to an Azure File Sync group and a file name conflict occurs (e.g., 'File1.txt' exists on both the server and the cloud endpoint), Azure File Sync does not overwrite either file. Instead, it prevents data loss by keeping both versions. The file from the cloud endpoint retains its original name, while the file from the server endpoint is typically renamed by appending the server name and a conflict hash to the filename. Because no overwriting occurs, the first two statements are 'No'. Once the file from Share1 is synced up to the cloud endpoint (even under its modified conflict-resolution name), it becomes part of the shared sync namespace. When Share2 is added later, it will download all files from the cloud endpoint, meaning the data from Share1 will indeed replicate to Share2. Therefore, the third statement is 'Yes'.

Common mistakes.

• common_mistake. A common misconception is assuming that cloud data automatically takes precedence over on-premises data (or vice versa), leading to one file overwriting the other. Users might also incorrectly assume that file name conflicts cause sync failures that prevent replication altogether.
