NEW QUESTION 33
Mule applications that implement a number of REST APIs are deployed to their own subnet that is inaccessible from outside the organization.
External business-partners need to access these APIs, which are only allowed to be invoked from a separate subnet dedicated to partners - called Partner-subnet. This subnet is accessible from the public internet, which allows these external partners to reach it.
Anypoint Platform and Mule runtimes are already deployed in Partner-subnet. These Mule runtimes can already access the APIs.
What is the most resource-efficient solution to comply with these requirements, while having the least impact on other applications that are currently using the APIs?
- A. Implement (or generate) an API proxy Mule application for each of the APIs, then deploy the API proxies to the Mule runtimes
- B. Duplicate the APIs as Mule applications, then deploy them to the Mule runtimes
- C. Redeploy the API implementations to the same servers running the Mule runtimes
- D. Add an additional endpoint to each API for partner-enablement consumption
Answer: A
NEW QUESTION 34

NEW QUESTION 35
What is a key requirement when using an external Identity Provider for Client Management in Anypoint Platform?

NEW QUESTION 36
Refer to the exhibit.
Three business processes need to be implemented, and the implementations need to communicate with several different SaaS applications.
These processes are owned by separate (siloed) LOBs and are mainly independent of each other, but do share a few business entities. Each LOB has one development team and their own budget In this organizational context, what is the most effective approach to choose the API data models for the APIs that will implement these business processes with minimal redundancy of the data models?
A) Build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities
B) Build distinct data models for each API to follow established micro-services and Agile API-centric practices
C) Build all API data models using XML schema to drive consistency and reuse across the organization
D) Build one centralized Canonical Data Model (Enterprise Data Model) that unifies all the data types from all three business processes, ensuring the data model is consistent and non-redundant

NEW QUESTION 39
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. A higher number of discoverable API-related assets in the application network
- B. A better response time for the end user as a result of the APIs being smaller in scope and complexity
- C. A decrease in the number of connections within the application network supporting the business process

NEW QUESTION 41
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: B
NEW QUESTION 42
What correctly characterizes unit tests of Mule applications?
- A. They must be triggered by an external client tool or event source
- B. They test the validity of input and output of source and target systems

- D. They are typically written using MUnit to run in an embedded Mule runtime that does not require external connectivity

NEW QUESTION 43
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.
Assume the downstream API runs uninterrupted without crashing. What is the impact of this advice?
- 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
Answer: B

What step of gaining access to the API can be performed automatically by Anypoint Platform?
- A. Create a new application in Anypoint Exchange for requesting access to the API
- B. Approve the client application request for the chosen SLA tier
