   A healthcare provider is migrating from a legacy NAS to ECS for medical imaging. The workload is 70% writes during the day and 90% reads at night. They need to ensure consistent performance during both periods. Which performance-impacting factor should they prioritize in their design?

   • ANetwork bandwidth
   • BCPU and memory configuration
   • CI/O size and concurrency settings
   • DStorage capacity

   A cloud service provider offers ECS-based object storage to tenants. They notice that one tenant's workload (many small random reads) degrades performance for other tenants. Which configuration change would best isolate the noisy neighbor?

   • AEnable compression for all tenants
   • BIncrease the replication factor for all tenants
   • CReduce the chunk size for all tenants
   • DEnable quality of service (QoS) limits per tenant
