   A storage administrator is analyzing capacity utilization for a large enterprise. The Data Exclusion report shows that 30% of used capacity is excluded (snapshots and internal copies). The Headroom report shows a headroom of 25%. The administrator must present a summary to management. Which statement is most accurate?

   • AThe array is overcommitted because excluded data exceeds headroom.
   • BThe array has 5% overcommitment (30% excluded - 25% headroom).
   • CThe array has 25% headroom, which is the capacity available for future growth after excluding snapshots and internal copies.
   • DThe array has 55% available capacity (30% excluded + 25% headroom).

   A company is considering a new disaster recovery (DR) site that will double the storage requirements. The current Headroom report shows a headroom of 40%. The administrator must decide if the current array can support the DR site without additional purchases. Which consideration is most important?

   • AThe DR site can use the same storage, so headroom is not a factor.
   • BThe DR site can be configured to use Data Exclusion to reduce its capacity footprint.
   • CThe DR site can be placed on the same array without affecting headroom.
   • DThe DR site will double the storage requirements, so the current headroom of 40% is insufficient.
