NEW QUESTION 37
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 C
- D. Option B
Answer: A
Explanation:
Correct answer: Build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities.
*****************************************
>> The options w.r.t building API data models using XML schema/ Agile API-centric practices are irrelevant to the scenario given in the question. So these two are INVALID.
>> Building EDM (Enterprise Data Model) is not feasible or right fit for this scenario as the teams and LOBs work in silo and they all have different initiatives, budget etc.. Building EDM needs intensive coordination among all the team which evidently seems not possible in this scenario.
So, the right fit for this scenario is to build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities.

- A. The SSL certificates used by the API implementation to expose HTTPS endpoints
- B. The number of DNS entries allocated to the API implementation
- C. The logging configuration that enables log entries to be visible in Runtime Manager
- D. The assignment of each HTTP request to a particular CloudHub worker
Answer: B
NEW QUESTION 41
Refer to the exhibit. An organization is running a Mule standalone runtime and has configured Active Directory as the Anypoint Platform external Identity Provider. The organization does not have budget for other system components.
What policy should be applied to all instances of APIs in the organization to most effecuvelyKestrict access to a specific group of internal users?
- A. Apply an IP whitelist policy; only the specific users' workstations will be in the whitelist
- B. Apply a client ID enforcement policy; the specific group of users will configure their client applications to use their specific client credentials
- C. Apply an OAuth 2.0 access token enforcement policy; the internal Active Directory will be configured as the OAuth server
- D. Apply a basic authentication - LDAP policy; the internal Active Directory will be configured as the LDAP source for authenticating users

NEW QUESTION 43
In an organization, the InfoSec team is investigating Anypoint Platform related data traffic.
From where does most of the data available to Anypoint Platform for monitoring and alerting originate?
- A. From the Mule runtime or the API Manager, depending on the type of data
- B. From the Mule runtime irrespective of the deployment model
- C. From various components of Anypoint Platform, such as the Shared Load Balancer, VPC, and Mule runtimes
- D. From the Mule runtime or the API implementation, depending on the deployment model
Answer: B
Explanation:
Correct answer: From the Mule runtime irrespective of the deployment model
*****************************************
>> Monitoring and Alerting metrics are always originated from Mule Runtimes irrespective of the deployment model.
>> It may seems that some metrics (Runtime Manager) are originated from Mule Runtime and some are (API Invocations/ API Analytics) from API Manager. However, this is realistically NOT TRUE. The reason is, API manager is just a management tool for API instances but all policies upon applying on APIs eventually gets executed on Mule Runtimes only (Either Embedded or API Proxy).
>> Similarly all API Implementations also run on Mule Runtimes.
So, most of the day required for monitoring and alerts are originated fron Mule Runtimes only irrespective of whether the deployment model is MuleSoft-hosted or Customer-hosted or Hybrid.
NEW QUESTION 44
An API implementation is deployed on a single worker on CloudHub and invoked by external API clients (outside of CloudHub). How can an alert be set up that is guaranteed to trigger AS SOON AS that API implementation stops responding to API invocations?
- A. Create an alert for when the API receives no requests within a specified time period
- B. Configure a "worker not responding" alert in Anypoint Runtime Manager
- C. Handle API invocation exceptions within the calling API client and raise an alert from that API client when the API Is unavailable
- D. Implement a heartbeat/health check within the API and invoke it from outside the Anypoint Platform and alert when the heartbeat does not respond
Answer: A
NEW QUESTION 45
When using CloudHub with the Shared Load Balancer, what is managed EXCLUSIVELY by the API implementation (the Mule application) and NOT by Anypoint Platform?
- A. The SSL certificates used by the API implementation to expose HTTPS endpoints
- B. The logging configuration that enables log entries to be visible in Runtime Manager
- C. The number of DNS entries allocated to the API implementation
- D. The assignment of each HTTP request to a particular CloudHub worker
Answer: B
NEW QUESTION 46
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. 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. 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: C
NEW QUESTION 47
An API implementation is being designed that must invoke an Order API, which is known to repeatedly experience downtime.
For this reason, a fallback API is to be called when the Order API is unavailable.
What approach to designing the invocation of the fallback API provides the best resilience?
- A. Set an option in the HTTP Requester component that invokes the Order API to instead invoke a fallback API whenever an HTTP 4xx or 5xx response status code is returned from the Order API
- B. Create a separate entry for the Order API in API Manager, and then invoke this API as a fallback API if the primary Order API is unavailable
- C. Redirect client requests through an HTTP 307 Temporary Redirect status code to the fallback API whenever the Order API is unavailable
- D. Search Anypoint Exchange for a suitable existing fallback API, and then implement invocations to this fallback API in addition to the Order API
Answer: C

NEW QUESTION 52
Refer to the exhibit.
A developer is building a client application to invoke an API deployed to the STAGING environment that is governed by a client ID enforcement policy.
What is required to successfully invoke the API?
- A. A valid OAuth token obtained from Anypoint Platform and its associated client ID and secret
- B. The client ID and secret for the Anypoint Platform account owning the API in the STAGING environment
- C. The client ID and secret for the Anypoint Platform account's STAGING environment
- D. The client ID and secret obtained from Anypoint Exchange for the API instance in the STAGING environment
Answer: D
Explanation:
Correct answer: The client ID and secret obtained from Anypoint Exchange for the API instance in the STAGING environment
*****************************************
>> We CANNOT use the client ID and secret of Anypoint Platform account or any individual environments for accessing the APIs
>> As the type of policy that is enforced on the API in question is "Client ID Enforcment Policy", OAuth token based access won't work.
Right way to access the API is to use the client ID and secret obtained from Anypoint Exchange for the API instance in a particular environment we want to work on.
