   Which of the following best describes the effect of an active snapshot on the guest operating system's performance?

   • AThe guest OS may experience degraded storage performance because writes are redirected to a delta disk, and reads may require additional I/O operations.
   • BThe guest OS will automatically optimize its I/O scheduler to compensate for the snapshot, resulting in no noticeable impact.
   • CThe guest OS experiences no performance impact because snapshots are handled entirely by the hypervisor.
   • DThe guest OS will experience a complete halt of all disk I/O until the snapshot is consolidated.

   A vSphere administrator is managing a VM that hosts a database with high write I/O. The VM has a snapshot that was taken 2 days ago. The administrator notices that the snapshot delta file has grown to 50 GB, and the VM's performance has degraded significantly. The administrator needs to restore the VM to a state before the snapshot was taken, but the database is still in use. What is the best course of action?

   • ADelete the snapshot immediately to restore performance, then use a backup to restore the database.
   • BIncrease the VM's memory and CPU to compensate for the snapshot overhead.
   • CTake a new snapshot to create a restore point, then delete the old snapshot to improve performance.
   • DRevert to the snapshot to restore the VM to its state before the snapshot, accepting that any changes since then will be lost.
