NEW QUESTION 20
What is true about automating interactions with Anypoint Platform using tools such as Anypoint Platform REST APIs, Anypoint CU, 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

- D. 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
Answer: D

NEW QUESTION 22
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 23
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
- A. Option A
- B. Option D
- C. Option B
- D. Option C
Answer: A
NEW QUESTION 24
Refer to the exhibit.
What is the best way to decompose one end-to-end business process into a collaboration of Experience, Process, and System APIs?
A) Handle customizations for the end-user application at the Process API level rather than the Experience API level
B) Allow System APIs to return data that is NOT currently required by the identified Process or Experience APIs
C) Always use a tiered approach by creating exactly one API for each of the 3 layers (Experience, Process and System APIs)
D) Use a Process API to orchestrate calls to multiple System APIs, but NOT to other Process APIs
- A. Option D
- B. Option C
- C. Option A
- D. Option B
Answer: B
NEW QUESTION 25
An organization makes a strategic decision to move towards an IT operating model that emphasizes consumption of reusable IT assets using modern APIs (as defined by MuleSoft).
What best describes each modern API in relation to this new IT operating model?
- A. Each modern API has its own software development lifecycle, which reduces the need for documentation and automation.
- B. Each modern API must be REST and HTTP based.
- C. Each modern API must be treated like a product and designed for a particular target audience (for instance, mobile app developers)
- D. Each modern API must be easy to consume, so should avoid complex authentication mechanisms such as SAML or JWT.
Answer: C
NEW QUESTION 26
What Mule application deployment scenario requires using Anypoint Platform Private Cloud Edition or Anypoint Platform for Pivotal Cloud Foundry?
- A. When regulatory requirements mandate on-premises processing of EVERY data item, including meta-data
- B. When ALL backend systems in the application network are deployed in the organization's intranet
- C. When it Is required to make ALL applications highly available across multiple data centers
- D. When it is required that ALL APIs are private and NOT exposed to the public cloud
Answer: B
NEW QUESTION 27
A Mule application exposes an HTTPS endpoint and is deployed to the CloudHub Shared Worker Cloud. All traffic to that Mule application must stay inside the AWS VPC.
To what TCP port do API invocations to that Mule application need to be sent?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
NEW QUESTION 28
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. An overall lower usage of resources because each fine-grained API consumes less resources.
- 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.
Answer: D
NEW QUESTION 29
An organization has implemented a Customer Address API to retrieve customer address information. This API has been deployed to multiple environments and has been configured to enforce client IDs everywhere.
A developer is writing a client application to allow a user to update their address. The developer has found the Customer Address API in Anypoint Exchange and wants to use it in their client application.
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. Request access to the appropriate API Instances deployed to multiple environments using the client application's credentials
- C. Modify the client application to call the API using the client application's credentials
- D. Approve the client application request for the chosen SLA tier
Answer: B

Answer: C
NEW QUESTION 31
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 32
What is most likely NOT a characteristic of an integration test for a REST API implementation?
- A. The test runs immediately after the Mule application has been compiled and packaged
- B. The test is triggered by an external HTTP request

- D. The test needs all source and/or target systems configured and accessible
Answer: C
NEW QUESTION 33
What correctly characterizes unit tests of Mule applications?
