Q28. 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

Option A

Option B

Option C

Option D

Q29. An API has been updated in Anypoint Exchange by its API producer from version 3.1.1 to 3.2.0 following accepted semantic versioning practices and the changes have been communicated via the API’s public portal.
The API endpoint does NOT change in the new version.
How should the developer of an API client respond to this change?

The update should be identified as a project risk and full regression testing of the functionality that uses this API should be run

The API producer should be contacted to understand the change to existing functionality

The API producer should be requested to run the old version in parallel with the new one

The API client code ONLY needs to be changed if it needs to take advantage of new features

Q30. 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?

Search Anypoint Exchange for a suitable existing fallback API, and then implement invocations to this fallback API in addition to the Order API

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

Redirect client requests through an HTTP 307 Temporary Redirect status code to the fallback API whenever the Order API is unavailable

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

Q31. The responses to some HTTP requests can be cached depending on the HTTP verb used in the request. According to the HTTP specification, for what HTTP verbs is this safe to do?

PUT, POST, DELETE

GET, HEAD, POST

Always use a tiered approach by creating exactly one API for each of the 3 layers (Experience, Process and System APIs).

Use a Process API to orchestrate calls to multiple System APIs, but NOT to other Process APIs.

Q37. An organization is deploying their new implementation of the OrderStatus System API to multiple workers in CloudHub. This API fronts the organization’s on-premises Order Management System, which is accessed by the API implementation over an IPsec tunnel.
What type of error typically does NOT result in a service outage of the OrderStatus System API?

A CloudHub worker fails with an out-of-memory exception

API Manager has an extended outage during the initial deployment of the API implementation

The AWS region goes offline with a major network failure to the relevant AWS data centers

The Order Management System is Inaccessible due to a network outage in the organization’s on-premises data center

Q38. What is a key requirement when using an external Identity Provider for Client Management in Anypoint Platform?

Single sign-on is required to sign in to Anypoint Platform

The application network must include System APIs that interact with the Identity Provider

To invoke OAuth 2.0-protected APIs managed by Anypoint Platform, API clients must submit access tokens issued by that same Identity Provider

APIs managed by Anypoint Platform must be protected by SAML 2.0 policies

The API policy Is defined in API Manager and then automatically applied to ALL API instances

The API policy is defined in API Manager, and then applied to ALL API instances in the specified environment

Q43. An organization has created an API-led architecture that uses various API layers to integrate mobile clients with a backend system. The backend system consists of a number of specialized components and can be accessed via a REST API. The process and experience APIs share the same bounded-context model that is different from the backend data model. What additional canonical models, bounded-context models, or anti-corruption layers are best added to this architecture to help process data consumed from the backend system?

Create a bounded-context model for every layer and overlap them when the boundary contexts overlap, letting API developers know about the differences between upstream and downstream data models

Create a canonical model that combines the backend and API-led models to simplify and unify data models, and minimize data transformations.

Create a bounded-context model for the system layer to closely match the backend data model, and add an anti-corruption layer to let the different bounded contexts cooperate across the system and process layers

Create an anti-corruption layer for every API to perform transformation for every data model to match each other, and let data simply travel between APIs to avoid the complexity and overhead of building canonical models

Q44. How are an API implementation, API client, and API consumer combined to invoke and process an API?

The API consumer creates an API implementation, which receives API invocations from an API such that they are processed for an API client

The API client creates an API consumer, which receives API invocations from an API such that they are processed for an API implementation

The ApI consumer creates an API client, which sends API invocations to an API such that they are processed by an API implementation

The ApI client creates an API consumer, which sends API invocations to an API such that they are processed by an API implementation

Q45. Refer to the exhibit.

An organization uses one specific CloudHub (AWS) region for all CloudHub deployments.
How are CloudHub workers assigned to availability zones (AZs) when the organization’s Mule applications are deployed to CloudHub in that region?

Workers belonging to a given environment are assigned to the same AZ within that region

AZs are selected as part of the Mule application’s deployment configuration

Workers are randomly distributed across available AZs within that region

An AZ is randomly selected for a Mule application, and all the Mule application’s CloudHub workers are assigned to that one AZ

Q46. What Mule application can have API policies applied by Anypoint Platform to the endpoint exposed by that Mule application?

A Mule application that accepts requests over HTTP/1x.

A Mule application that accepts JSON requests over TCP but is NOT required to provide a response.

A Mule application that accepts JSON requests over WebSocket.

A Mule application that accepts gRPC requests over HTTP/2
