Business Requirements include: Guarantee service availability and support. I would choose C
👍 36VASI2020/02/17Answer is C; more complete imo. Those aligning to D should note that average latency is not the only metric available to measure and is too specific.
"Total visits" covers the business requirements:
- Optimize for capacity during peak periods and value during off-peak periods.
- Expand services into Asia.
"Error rates" covers business requirement:
- Guarantee service availability and support. ** if service is unavailable, errors are reported!
"Latency" covers technical requirement:
- Decrease latency in Asia.
