AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

A company runs analytics on 100 EC2 instances in two Availability Zones, sharing an Amazon EFS Regional file system in General Purpose performance mode with Bursting throughput. During periodic spikes that issue thousands of parallel metadata operations, engineers see high client I/O wait and the PercentIOLimit metric at 100%. Without migrating data or disruption, how can they BEST reduce these latency spikes?

  • Enable Provisioned throughput and set a value twice the current baseline.

  • Convert the file system to the Amazon EFS One Zone storage class.

  • Store additional data in the file system to increase its burst throughput limits.

  • Change the file system's throughput mode to Elastic throughput.
