   A government agency is starting the design of an ECS solution for long-term records retention. The project sponsor wants to skip requirements gathering and move directly to architecture design to save time. The architect must recommend the correct end-to-end process. What should the architect do?

   • AAsk the sponsor to approve the design without any documentation to save time
   • BProceed with architecture design and document requirements after the design is approved
   • CInsist on completing requirements gathering first because it identifies the retention, access, and compliance constraints that drive the architecture
   • DSkip requirements gathering but perform validation testing to catch any missing requirements

   A government agency has designed an ECS solution for citizen records. The design specifies a 5-node cluster with replication factor 3. The validation team must confirm the solution meets the 99.999% availability requirement. The team has a limited budget and cannot perform destructive testing on the production cluster. Which validation approach is MOST appropriate?

   • AUse the vendor's published availability figures instead of testing
   • BReview the replication factor of 3 and assume the availability requirement is met
   • CPerform fault injection tests on the production cluster during a maintenance window
   • DBuild a small test cluster that mirrors the production design and perform fault injection tests on it

   A manufacturing company is designing an ECS solution to store IoT sensor data from multiple factories. Each factory sends data over a private MPLS network to a central data center. The architect must design the data flow. Which architecture component is MOST critical to include in the design?

   • AA public cloud replication target for all IoT data
   • BA dedicated ECS namespace per factory to isolate data and simplify access control
   • CA load balancer in front of the ECS cluster to distribute ingest traffic
   • DA single shared namespace for all factories to reduce management overhead

   A media company is designing an ECS solution for a new video archive. The archive team states that the system must retain 500 TB of footage for 7 years, with new footage added at 2 TB per day. The compliance officer adds that footage must be retrievable within 5 minutes of a legal request. During requirements gathering, which activity is MOST important to perform before any capacity calculations?

   • AInterview only the archive team to confirm the 500 TB figure
   • BDocument the retention period, ingest rate, and retrieval SLA as formal non-functional requirements
   • CCalculate the total raw capacity needed by multiplying 500 TB by 7 years
   • DSelect the ECS node model that best fits the 500 TB footprint

   A national archive is designing an ECS solution for digitized historical records. The archive must retain records for 100 years, but the initial ingest is only 50 TB with a growth rate of 5% per year. The archive also requires that records be retrievable within 24 hours of a request. The architect must balance long-term capacity planning with the retrieval SLA. Which approach is MOST appropriate?

   • ASelect the largest ECS node model available to avoid future capacity upgrades
   • BDesign for the full 100-year retention period in a single capacity calculation
   • CIgnore the retrieval SLA because the retention period is the primary requirement
   • DDesign for a 10-year capacity horizon with a documented refresh plan, and validate that the retrieval SLA is met on the current hardware
