A customer is facing poor performance on all synchronously replicated volumes every Thursday between 4 PM and 6 PM. All departments have checked their applications for any batch jobs; however, nothing was found. The I/O graphs do not show any anomaly and the replication links are not saturated.
What is the possible reason for this behavior?

  1. Switches used for replication are restarting
  2. QoS Bandwidth Limit is enabled in the QoS node
  3. Data Progression is consuming all disk performance
  4. Automatic report creation is impacting replication

Answer(s): B



A customer is concerned they are over utilizing their 7K drives.

  2. Charting > Disks > [disk folder] IO Charts
  3. Charting > Disks > [disk folder] > [disk number]
  4. Hardware > Disks > [disk folder]

Which zones accurately describe the zoning requirement for replication connectivity to be established when the source array is in Legacy Port Mode and the target array is in Virtual Port Mode?

  1. Zone 1 = All Source Virtual Port WWNs + All Remote Physical Port WWNsZone 2 = All Source Physical Port WWNs + All Remote Virtual Port WWNs
  2. Zone 1 = All Physical WWNs from both arraysZone 2 = All Virtual WWNs from both arrays
  3. Zone 1 = All Source WWNs + All Remote Virtual Port WWNsZone 2 = All Source WWNs + All Remote Physical Port WWNs
  4. Zone 1 = All Source Virtual Port WWNs + All Remote Port WWNsZone 2 = All Source Physical Port WWNs + All Remote Port WWNs
