   A financial services company runs a MySQL database on a single EC2 instance. The database requires consistently high IOPS for transaction processing, with a peak demand of 40,000 IOPS and a storage capacity of 2 TB. The workload is latency-sensitive and the company wants to minimize cost while meeting performance requirements. Which EBS volume type should the company choose?

   • AProvisioned IOPS SSD (io2 Block Express)
   • BCold HDD (sc1)
   • CGeneral Purpose SSD (gp3)
   • DThroughput Optimized HDD (st1)

   A company is designing a data lake on Amazon S3. The data lake will store raw data from IoT devices, processed data from analytics jobs, and archival data. The company expects data volume to grow from 50 TB to 1 PB over 3 years. They need to minimize storage costs while ensuring that frequently accessed data has low latency and archival data is retained for 7 years. Which S3 storage class configuration should they use?

   • AUse S3 One Zone-IA for all data to reduce costs, as the data can be regenerated from IoT devices.
   • BUse S3 Standard for frequently accessed data, S3 Standard-IA for infrequently accessed data, and S3 Glacier Deep Archive for archival data, with lifecycle policies to transition data between classes.
   • CStore all data in S3 Glacier Deep Archive to minimize costs, and use S3 Object Lambda to retrieve data on demand.
   • DStore all data in S3 Standard to ensure low latency and high durability, regardless of access frequency.
