Which pattern should be used to invoke multiple HTTP APIs in parallel and roll back failed requests in sequence?

• A.Scatter-Gather as central Saga orchestrator for all API request with compensating actions for failing routes
• B.A database as a transactional outbox and an Until Successful router to retry any requests
• C.VM queues as a reliability pattern with error handlers to roll back any requests
• D.A Parallel for Each scope with each HTTP request wrapped in a Try scope

When registering a client application with an existing API instance or API Group instance, what is required to manually approve or reject request access?

• A.To configure the SLA tier for the application
• B.To configure the SLA tier for the application and have the Exchange Administrator permission
• C.To configure the SLA tier for the application and have the role of Organization Administrator, API Manager Environment Administrator, or the Manage Contacts permission
• D.To only have Exchange Administrator permission

A Mule application deployed to multiple Cloudhub 2.0 replicas needs to temporarily persist large files over
10MB between flow executions, and routinely needs to query whether the file data exists on separate executions.
How can this be achieved?

• A.Store the key and full contents of the file, caching the filename and location between requests
• B.Use an in-memory Object Store
• C.Store the key and full contents of the file in an Object Store
• D.Store the contents of the file on separate storage, and store the key and location of the file Object using Object Store v2

Mule application A is deployed to CloudHub and is using Object Store v2. Mute application B is also deployed to CloudHub.
Which approach can Mule application B use to remove values from Mule application A'S Object Store?

• A.Object Store v2 REST API
• B.CloudHub Connector
• C.Object Store Connector
• D.CloudHub REST API

The flow is invoicing a target API. The API's protocol is HTTPS. The TLS configuration in the HTTP Request Configuration global element is set to None. A web client submits a request to
http:localhost:8081/vehicles.

If the certificate of the target API is signed by a certificate authority (CA), what is true about the HTTP Request operation when the flow executes?

• A.The HTTP Request operation will always succeed regardless of the CA
• B.The HTTP Request operation will succeed if the CA's certificate is present in the JRE's default truststore.
• C.The HTTP Request operation will always fail regardless of the CA
• D.The HTTP Request operation will succeed if the CA'S certificate is present in the JRE's default keystore
