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

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?

• A.The API producer should be contacted to understand the change to existing functionality
• B.The API client code ONLY needs to be changed if it needs to take advantage of new features
• C.The update should be identified as a project risk and full regression testing of the functionality that uses this API should be run
• D.The API producer should be requested to run the old version in parallel with the new one

What do the API invocation metrics provided by Anypoint Platform provide?

• A.ROI metrics from APIs that can be directly shared with business users
• B.Measurements of the effectiveness of the application network based on the level of reuse
• C.Data on past API invocations to help identify anomalies and usage patterns across various APIs
• D.Proactive identification of likely future policy violations that exceed a given threat threshold

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?

• A.Workers are randomly distributed across available AZs within that region
• B.AZs are selected as part of the Mule application's deployment configuration
• C.An AZ is randomly selected for a Mule application, and all the Mule application's CloudHub workers are assigned to that one AZ
• D.Workers belonging to a given environment are assigned to the same AZ within that region

What condition requires using a CloudHub Dedicated Load Balancer?

• A.When API invocations across multiple CloudHub workers must be load balanced
• B.When server-side load-balanced TLS mutual authentication is required between API implementations and API clients
• C.When cross-region load balancing is required between separate deployments of the same Mule application
• D.When custom DNS names are required for API implementations deployed to customer-hosted Mule runtimes
