   A telecom company stores call detail records (CDRs) on ECS. The workload is write-heavy during peak hours and read-heavy during off-peak hours for analytics. They need to balance write throughput during peak and read performance during off-peak. Which configuration approach best meets both requirements?

   • AUse separate buckets with different configurations for writes and reads
   • BUse a single configuration optimized for writes
   • CUse a single configuration optimized for reads
   • DEnable compression to reduce storage and improve both

   • AConfiguring the appropriate number of storage pools and replication factors
   • BSetting the system clock to a fixed time
   • CUsing the default settings for all parameters
   • DDisabling all background maintenance tasks

   A media company stores large video files (2–8 GB) on ECS. Their workload is 95% write-once-read-many, with reads happening days after writes. During initial ingest, they notice high latency and want to improve write throughput. Which workload characteristic is the primary factor to address?

   • AOptimize I/O size by using larger chunk sizes for writes
   • BReduce concurrency during ingest to avoid contention
   • CIncrease the read/write ratio by pre-staging content
   • DSwitch to smaller object sizes to parallelize writes

   A government agency uses ECS for document management. The workload is 60% small objects (under 64 KB) and 40% large objects (over 1 MB). They observe that small object operations are slower than expected. Which hardware component should they upgrade to improve small object performance?

   • ANetwork interface cards
   • BStorage node CPU
   • CDisk drive speed
   • DStorage node memory

   A scientific research organization stores simulation output on ECS. The workload is 95% writes of large files (50–100 GB) and 5% reads for verification. Writes are sequential, but reads are random access to specific data ranges. They are experiencing slow writes. Which workload characteristic should they adjust to improve write performance?

   • ADecrease chunk size for writes
   • BIncrease chunk size for writes
   • CDecrease concurrency for writes
   • DIncrease concurrency for writes
