NEW QUESTION 29
The implementation of a Process API must change.
What is a valid approach that minimizes the impact of this change on API clients?

Update the RAML definition of the current Process API and notify API client developers by sending them links to the updated RAML definition

Postpone changes until API consumers acknowledge they are ready to migrate to a new Process API or API version

Implement required changes to the Process API implementation so that whenever possible, the Process API’s RAML definition remains unchanged

Implement the Process API changes in a new API implementation, and have the old API implementation return an HTTP status code 301 – Moved Permanently to inform API clients they should be calling the new API implementation

NEW QUESTION 31
A set of tests must be performed prior to deploying API implementations to a staging environment. Due to data security and access restrictions, untested APIs cannot be granted access to the backend systems, so instead mocked data must be used for these tests. The amount of available mocked data and its contents is sufficient to entirely test the API implementations with no active connections to the backend systems. What type of tests should be used to incorporate this mocked data?

Integration tests

Performance tests

Functional tests (Blackbox)

Unit tests (Whitebox)

NEW QUESTION 32
What is a key performance indicator (KPI) that measures the success of a typical C4E that is immediately apparent in responses from the Anypoint Platform APIs?

The number of production outage incidents reported in the last 24 hours

The number of API implementations that have a publicly accessible HTTP endpoint and are being managed by Anypoint Platform

The fraction of API implementations deployed manually relative to those deployed using a CI/CD tool

The number of API specifications in RAML or OAS format published to Anypoint Exchange

NEW QUESTION 33
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.

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

NEW QUESTION 36
A system API has a guaranteed SLA of 100 ms per request. The system API is deployed to a primary environment as well as to a disaster recovery (DR) environment, with different DNS names in each environment. An upstream process API invokes the system API and the main goal of this process API is to respond to client requests in the least possible time. In what order should the system APIs be invoked, and what changes should be made in order to speed up the response time for requests from the process API?

In parallel, invoke the system API deployed to the primary environment and the system API deployed to the DR environment, and ONLY use the first response

In parallel, invoke the system API deployed to the primary environment and the system API deployed to the DR environment using a scatter-gather configured with a timeout, and then merge the responses

Invoke the system API deployed to the primary environment, and if it fails, invoke the system API deployed to the DR environment

Invoke ONLY the system API deployed to the primary environment, and add timeout and retry logic to avoid intermittent failures

NEW QUESTION 37
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?

The client ID and secret for the Anypoint Platform account’s STAGING environment

The client ID and secret obtained from Anypoint Exchange for the API instance in the STAGING environment

A valid OAuth token obtained from Anypoint Platform and its associated client ID and secret

NEW QUESTION 38
What CANNOT be effectively enforced using an API policy in Anypoint Platform?

Guarding against Denial of Service attacks

Maintaining tamper-proof credentials between APIs

Logging HTTP requests and responses

Backend system overloading

NEW QUESTION 39
What is typically NOT a function of the APIs created within the framework called API-led connectivity?

They provide an additional layer of resilience on top of the underlying backend system, thereby insulating clients from extended failure of these systems.

They allow for innovation at the user Interface level by consuming the underlying assets without being aware of how data Is being extracted from backend systems.

They reduce the dependency on the underlying backend systems by helping unlock data from backend systems In a reusable and consumable way.

They can compose data from various sources and combine them with orchestration logic to create higher level value.

NEW QUESTION 40
What best explains the use of auto-discovery in API implementations?

It makes API Manager aware of API implementations and hence enables it to enforce policies

It enables Anypoint Studio to discover API definitions configured in Anypoint Platform

It enables Anypoint Exchange to discover assets and makes them available for reuse

It enables Anypoint Analytics to gain insight into the usage of APIs

NEW QUESTION 41
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
