D) A Mule application that accepts gRPC requests over HTTP/2
- A. Option A
- B. Option C
- C. Option B
- D. Option D

NEW QUESTION 39
The implementation of a Process API must change.
What is a valid approach that minimizes the impact of this change on API clients?
- A. Postpone changes until API consumers acknowledge they are ready to migrate to a new Process API or API version.
- B. Update the RAML definition of the current Process API and notify API client developers by sending them links to the updated RAML definition.
- C. Implement the Process API changes in a new API implementation, and have the old API implementation return an HTTP status code 301 - Moved Permanentlyto inform API clients they should be calling the new API implementation.
- D. Implement required changes to the Process API implementation so that, whenever possible, the Process API's RAML definition remains unchanged.

NEW QUESTION 40
What is true about automating interactions with Anypoint Platform using tools such as Anypoint Platform REST APIs, Anypoint CLI, or the Mule Maven plugin?
- A. Anypoint Platform APIs can ONLY automate interactions with CloudHub, while the Mule Maven plugin is required for deployment to customer-hosted Mule runtimes
- B. API policies can be applied to the Anypoint Platform APIs so that ONLY certain LOBs have access to specific functions.
- C. By default, the Anypoint CLI and Mule Maven plugin are NOT included in the Mule runtime, so are NOT available to be used by deployed Mule applications.
- D. Access to Anypoint Platform APIs and Anypoint CLI can be controlled separately through the roles and permissions in Anypoint Platform, so that specific users can get access to Anypoint CLI while others get access to the platform APIs.
Answer: C
NEW QUESTION 41
When designing an upstream API and its implementation, the development team has been advised to NOT set timeouts when invoking a downstream API, because that downstream API has no SLA that can be relied upon.
This is the only downstream API dependency of that upstream API.
- A. Assume the downstream API runs uninterrupted without crashing. What is the impact of this advice?
- B. The invocation of the downstream API will run to completion without timing out
- C. A default timeout of 500 ms will automatically be applied by the Mule runtime in which the upstream API implementation executes
- D. A toad-dependent timeout of less than 1000 ms will be applied by the Mule runtime in which the downstream API implementation executes
- E. An SLA for the upstream API CANNOT be provided
Answer: C
NEW QUESTION 42

NEW QUESTION 44
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. 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
- D. Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until it responds
Answer: A
NEW QUESTION 45
