Question 1

When you review performance data for a NetApp ONTAP cluster node, there are back-to-back (B2B)
type consistency points (CPs) found occurring on the loot aggregate.
In this scenario, how will performance of the client operations on the data aggregates be affected?

  • A. During B2B processing, clients will be unable to write data.
  • B. Data aggregates will not be affected by B2B processing on another aggregate.
  • C. During B2B processing, all I/O to the node is stopped.
  • D. During B2B processing, clients will be unable to read data.

B. Data aggregates will not be affected by B2B processing on another aggregate.

Back-to-back (B2B) consistency points (CPs) occurring on the root aggregate do not directly affect the performance of client operations on the data aggregates. Each aggregate operates independently with its own CP process, so issues with CPs on the root aggregate will not impact the data aggregates' ability to handle client I/O operations.
