Exam MCPA-Level-1 Topic 7 Question 81 Discussion

Actual exam question for MuleSoft's MCPA-Level-1 exam
Question #: 81
Topic #: 7

A new upstream API Is being designed to offer an SLA of 500 ms median and 800 ms maximum (99th percentile) response time. The corresponding API implementation needs to sequentially invoke 3 downstream APIs of very similar complexity.
The first of these downstream APIs offers the following SLA for its response time: median: 100 ms, 80th percentile: 500 ms, 95th percentile: 1000 ms.
If possible, how can a timeout be set in the upstream API for the invocation of the first downstream API to meet the new upstream API's desired SLA?

A. Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries B. Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs to complete C. Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until it responds D. No timeout is possible to meet the upstream API's desired SLA; a different SLA must be negotiated with the first downstream API or invoke an alternative API
