An architect was in an architectural workshop and noted the following business objectives:
The solution must prioritize optimal end-to-end user shopping experience for customers accessing the
website.
The website must be available 24 x 7 x 365.
Which three conceptual model items relate to these business objectives? (Choose three.)
Answer
- A. A requirement to have 99.99% availability uptime measured at the front-end application layer Correct
- B. A risk that the external internet network provider does not meet the service level agreement (SLA) requirements Correct
- C. A requirement to have 99.99% availability uptime measured at the network infrastructure layer
- D. An assumption that site performance is not a key performance indicator (KPI) for the customer
- E. A constraint of any planned changes limited to outside of business hours only
- F. An assumption that there is sufficient budget for the design to meet the performance requirements Correct
Explanation
Conceptual model items are categorized as requirements, assumptions, risks, and constraints:A is a clear requirement, aligned with the business objective of continuous uptime and availability.
B is a valid risk, as the availability of the external internet provider impacts the user experience. F is an
assumption, implying that budget will not be a limitation in achieving the desired level of performance.
Items like C are too technically specific for the conceptual layer. D directly contradicts the business
objective, and E relates more to operational constraints rather than high-level design goals.
