SK0-005 server-administration Practice Question

Your organization is migrating a Windows Server 2019 file server with 2 TB of shared data to a new server running Windows Server 2022. The migration must minimize user downtime and ensure file permissions are preserved. Users access files during business hours (8 AM to 6 PM) and the migration must be completed within a four-hour window starting at 10 PM on Saturday. You plan to use DFS Replication (DFSR) for initial data copy and then perform a final synchronization during the cutover. After setting up DFSR between the old and new servers, you realize that the initial replication will take approximately 12 hours due to the large number of files. What should you do to complete the migration within the allowed window?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Use robocopy to pre-stage the data from old to new server during off-hours before the cutover, then enable DFSR to replicate only changes made after pre-staging; during the cutover window, do a final DFSR sync

Option C is correct because pre-staging data using robocopy with appropriate flags (copying security and attributes) and then enabling DFSR for the delta changes is a best practice for large migrations. Option A is wrong because simply increasing DFSR bandwidth does not reduce the time needed for initial replication of 2 TB. Option B is wrong because using robocopy alone during the cutover window may not complete within four hours if you need to copy all data; pre-staging is required. Option D is wrong because performing a full backup and restore during the window is too time-consuming for 2 TB.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Use robocopy to pre-stage the data from old to new server during off-hours before the cutover, then enable DFSR to replicate only changes made after pre-staging; during the cutover window, do a final DFSR sync

    Why this is correct

    Pre-staging reduces the data transferred during the cutover to only changes, allowing the final sync to complete within the window.

  • Disable DFSR and use robocopy with /MIR /COPYALL during the cutover window to copy all data

    Why it's wrong here

    Robocopy copying 2 TB over the network will likely exceed the four-hour window and cause user disruption.

  • Perform a full backup of the old server and restore to the new server during the cutover window using Windows Backup

    Why it's wrong here

    Full backup/restore of 2 TB over the network or locally will likely take longer than four hours, and may not preserve open file states.

  • Increase the DFSR staging quota and bandwidth throttling to accelerate initial replication

    Why it's wrong here

    Tuning settings cannot make initial replication of 2 TB complete in four hours; the data volume is too large.
