Salesforce Certified MuleSoft Platform Architect Sample Questions:

1. 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) 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
C) Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs to complete
D) Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until it responds

2. An operations team is analyzing the effort needed to set up monitoring of their application network. They are looking at which API invocation metrics can be used to identify and predict trouble without having to write custom scripts or install additional analytics software or tools.
Which type of metrics can satisfy this goal of directly identifying and predicting failures?

A) The ROI from each APT invocation
B) The effectiveness of the application network based on the level of reuse
C) The number and types of API policy violations per day
D) The number and types of past API invocations across the application network

3. A company is using an on-prem cluster in the data center as a runtime plane and MuleSoft-hosted control plane.
How can the company monitor the detailed performance metrics on the Mule applications deployed to the cluster from the control plane?

A) Monitoring Agent must be installed on each node in the cluster
B) The settings of the Monitoring section in the control plane must be updated to enable detailed logging on the metrics to be captured
C) Due to the potential performance impact on the runtime nodes, the Monitoring agent should be installed on a separate server
D) There is no action needed as the on-prem runtime automatically sends the performance data to the control plane

4. Which layer in the API-led connectivity focuses on unlocking key systems, legacy systems, data sources etc and exposes the functionality?

A) System Layer
B) Process Layer
C) Experience Layer

5. When could the API data model of a System API reasonably mimic the data model exposed by the corresponding backend system, with minimal improvements over the backend system's data model?

A) When there is an existing Enterprise Data Model widely used across the organization
B) When the corresponding backend system is expected to be replaced in the near future
C) When the System API can be assigned to a bounded context with a corresponding data model
D) When a pragmatic approach with only limited isolation from the backend system is deemed appropriate
