Question 66

What is a typical result of using a fine-grained rather than a coarse-grained API deployment model to implement a given business process?

A.An overall lower usage of resources because each fine-grained API consumes less resources.

B.A higher number of discoverable API-related assets in the application network.

C.A decrease in the number of connections within the application network supporting the business process.

D.A better response time for the end user as a result of the APIs being smaller in scope and complexity.

Question 67

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.Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until it responds

B.Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries

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.Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs to complete

Question 68

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.A default timeout of 500 ms will automatically be applied by the Mule runtime in which the upstream API implementation executes

B.Assume the downstream API runs uninterrupted without crashing. What is the impact of this advice?

C.A toad-dependent timeout of less than 1000 ms will be applied by the Mule runtime in which the downstream API implementation executes

D.An SLA for the upstream API CANNOT be provided

E.The invocation of the downstream API will run to completion without timing out

Question 69

What should be ensured before sharing an API through a public Anypoint Exchange portal?

A.The visibility level of the API instances of that API that need to be publicly accessible should be set to public visibility

B.The users needing access to the API should be added to the appropriate role in Anypoint Platform

C.The API should be functional with at least an initial implementation deployed and accessible for users to interact with

D.The API should be secured using one of the supported authentication/authorization mechanisms to ensure that data is not compromised

Question 70

A System API is designed to retrieve data from a backend system that has scalability challenges. What API policy can best safeguard the backend system?

A.SLA-based rate limiting

B.Auth 2 token enforcement

C.Client ID enforcement

D.IPwhitelist
