NEW QUESTION 29
Refer to the exhibit. An organization needs to enable access to their customer data from both a mobile app and a web application, which each need access to common fields as well as certain unique fields.
The data is available partially in a database and partially in a 3rd-party CRM system.
What APIs should be created to best fit these design requirements?
A) A Process API that contains the data required by both the web and mobile apps, allowing these applications to invoke it directly and access the data they need thereby providing the flexibility to add more fields in the future without needing API changes
B) One set of APIs (Experience API, Process API, and System API) for the web app, and another set for the mobile app
C) Separate Experience APIs for the mobile and web app, but a common Process API that invokes separate System APIs created for the database and CRM system
D) A common Experience API used by both the web and mobile apps, but separate Process APIs for the web and mobile apps that interact with the database and the CRM System
- A. Option A
- B. Option D
- C. Option B
- D. Option C
Answer: B
NEW QUESTION 30
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 toad-dependent timeout of less than 1000 ms will be applied by the Mule runtime in which the downstream API implementation executes
- B. A default timeout of 500 ms will automatically be applied by the Mule runtime in which the upstream API implementation executes
- C. The invocation of the downstream API will run to completion without timing out
- D. An SLA for the upstream API CANNOT be provided
- E. Assume the downstream API runs uninterrupted without crashing. What is the impact of this advice?
Answer: B

NEW QUESTION 33
How are an API implementation, API client, and API consumer combined to invoke and process an API?

- B. The API client creates an API consumer, which receives API invocations from an API such that they are processed for an API implementation
- C. The ApI consumer creates an API client, which sends API invocations to an API such that they are processed by an API implementation

NEW QUESTION 35
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 100 ms; that leaves 400 ms for the other two downstream APIs to complete
- B. Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries
- 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
Answer: A
NEW QUESTION 36
