QuestionQ78

Business Continuity

An administrator supports a business-critical environment and deploys metro availability to attain a zero-data-loss configuration. The two clusters are connected through a 1GbE connection. A new workload will be deployed to this cluster. This workload requires sustained write throughput of 150MB/s and read throughput of 20MB/s.

Which change must be made to deploy the workload successfully on this cluster?

  • A The bandwidth must be increased to support this workload.
  • B The workload must be configured to read at greater than 12.5MB/s.
  • C The replication frequency must be less than 60 minutes.
  • D Zero data loss nearsync must be used to support this workload.
Explanation

A zero-data-loss metro configuration synchronously replicates writes between the clusters. A 1GbE connection has a theoretical maximum of approximately 125MB/s, which is already below the required sustained 150MB/s write rate and will be lower in practice after overhead. The replication link therefore requires more bandwidth.
