What must be done after changes are verified on the primary CMM?

• A. The changes must be audited and logged locally
• B. The changes must be rolled back to factory defaults
• C. The changes must be saved to the certified directory
• D. The changes must be copied onto the secondary CMM

Answer: (D)

After changes are verified on the primary CMM, the next essential step is to copy those changes to the secondary CMM. This keeps both units in lockstep, ensuring that failover will preserve the same configuration and approved settings. Verification on the primary ensures only validated changes are propagated, preventing divergence. If the secondary isn’t updated, the system could behave inconsistently during a failure or maintenance. Other options don’t achieve the necessary synchronization between the two CMMs, which is why mirroring the validated changes to the secondary is required.
