Question No : 4
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.An SLA for the upstream API CANNOT be provided.
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.A load-dependent timeout of less than 1000 ms will be applied by the Mule runtime in which the downstream API implementation executes.

Question No : 5
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 implementation, depending on the deployment model
B.From various components of Anypoint Platform, such as the Shared Load Balancer, VPC, and Mule runtimes
C.From the Mule runtime or the API Manager, depending on the type of data
D.From the Mule runtime irrespective of the deployment model

Question No : 6
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.The client ID and secret for the Anypoint Platform account owning the API in the STAGING environment
B.The client ID and secret for the Anypoint Platform account's STAGING environment
C.The client ID and secret obtained from Anypoint Exchange for the API instance in the STAGING environment
D.A valid OAuth token obtained from Anypoint Platform and its associated client ID and secret

Question No : 7
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.

Question No : 8
The implementation of a Process API must change.
What is a valid approach that minimizes the impact of this change on API clients?

A.Update the RAML definition of the current Process API and notify API client developers by sending them links to the updated RAML definition.
B.Postpone changes until API consumers acknowledge they are ready to migrate to a new Process API or API version.
C.Implement required changes to the Process API implementation so that, whenever possible, the Process API's RAML definition remains unchanged.
D.Implement the Process API changes in a new API implementation, and have the old API implementation return an HTTP status code 301 - Moved Permanentlyto inform API clients they should be calling the new API implementation.

Question No : 9
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.Implement a heartbeat/health check within the API and invoke it from outside the Anypoint Platform and alert when the heartbeat does not respond.
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.Create an alert for when the API receives no requests within a specified time period.

Question No : 10
What is true about the technology architecture of Anypoint VPCs?

A.The private IP address range of an Anypoint VPC is automatically chosen by CloudHub.
B.Traffic between Mule applications deployed to an Anypoint VPC and on-premises systems can stay within a private network.
C.Each CloudHub environment requires a separate Anypoint VP
D.VPC peering can be used to link the underlying AWS VPC to an on-premises (non AWS) private network.
