Which Anypoint Platform component helps integration developers discovers and share reusable APIs, connectors, and templates?

• Anypoint Exchange
• API Manager
• Anypoint Studio
• Design Center

An API implementation is being developed to expose data from a production database via HTTP requests. The API implementation executes a database SELECT statement that is dynamically created based upon data received from each incoming HTTP request. The developers are planning to use various types of testing to make sure the Mule application works as expected, can handle specific workloads, and behaves correctly from an API consumer perspective. What type of testing would typically mock the results from each SELECT statement rather than actually execute it in the production database?

• Unit testing (white box)
• Integration testing
• Functional testing (black box)
• Performance testing

What condition requires using a CloudHub Dedicated Load Balancer?

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

Mule application is deployed to Customer Hosted Runtime. Asynchronous logging was implemented to improved throughput of the system. But it was observed over the period of time that few of the important exception log messages which were used to rollback transactions are not working as expected causing huge loss to the Organization. Organization wants to avoid these losses. Application also has constraints due to which they cant compromise on throughput much. What is the possible option in this case?

• Logging needs to be changed from asynchronous to synchronous
• External log appender needs to be used in this case
• Persistent memory storage should be used in such scenarios
• Mixed configuration of asynchronous or synchronous loggers should be used to log exceptions via synchronous way

An organization currently uses a multi-node Mule runtime deployment model within their datacenter, so each Mule runtime hosts several Mule applications. The organization is planning to transition to a deployment model based on Docker containers in a Kubernetes cluster. The organization has already created a standard Docker image containing a Mule runtime and all required dependencies (including a JVM), but excluding the Mule application itself.What is an expected outcome of this transition to container-based Mule application deployments?

• Required redesign of Mule applications to follow microservice architecture principles
• Required migration to the Docker and Kubernetes-based Anypoint Platform - Private Cloud Edition
• Required change to the URL endpoints used by clients to send requests to the Mule applications
• Guaranteed consistency of execution environments across all deployments of a Mule application

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

A new upstream API Is being designed to offer an SLA of 500 ms median and 800 ms maximum (99th percentile) response time. The corresponding API implementation needs to sequentially invoke 3 downstream APIs of very similar complexity. The first of these downstream APIs offers the following SLA for its response time: median: 100 ms, 80th percentile: 500 ms, 95th percentile: 1000 ms. If possible, how can a timeout be set in the upstream API for the invocation of the first downstream API to meet the new upstream API's desired SLA?

• Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs to complete
• Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until it responds
• Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries
• No timeout is possible to meet the upstream API's desired SLA; a different SLA must be negotiated with the first downstream API or invoke an alternative API

An organization has various integrations implemented as Mule applications. Some of these Mule applications are deployed to custom hosted Mule runtimes (on-premises) while others execute in the MuleSoft-hosted runtime plane (CloudHub). To perform the Integra functionality, these Mule applications connect to various backend systems, with multiple applications typically needing to access the backend systems.How can the organization most effectively avoid creating duplicates in each Mule application of the credentials required to access the backend systems?

• Create a Mule domain project that maintains the credentials as Mule domain-shared resources Deploy the Mule applications to the Mule domain, so the credentials are available to the Mule applications
• Store the credentials in properties files in a shared folder within the organization's data center Have the Mule applications load properties files from this shared location at startup
• Segregate the credentials for each backend system into environment-specific properties files Package these properties files in each Mule application, from where they are loaded at startup
• Configure or create a credentials service that returns the credentials for each backend system, and that is accessible from customer-hosted and MuleSoft-hosted Mule runtimes Have the Mule applications toad the properties at startup by invoking that credentials service

A system administrator needs to determine when permissions were last changed for an Anypoint Platform user.Which Anypoint Platform component should the administrator use to obtain this information?

• Audit Logging
• Anypoint Monitoring
• Anypiont Studio
• Mule Stack Traces

A mule application is deployed to a Single Cloudhub worker and the public URL appears in Runtime Manager as the APP URL.Requests are sent by external web clients over the public internet to the mule application App url. Each of these requests routed to the HTTPS Listener event source of the running Mule application.Later, the DevOps team edits some properties of this running Mule application in Runtime Manager.Immediately after the new property values are applied in runtime manager, how is the current Mule application deployment affected and how will future web client requests to the Mule application be handled?

• Cloudhub will redeploy the Mule application to the OLD Cloudhub worker New web client requests will RETURN AN ERROR until the Mule application is redeployed to the OLD Cloudhub worker
• CloudHub will redeploy the Mule application to a NEW Cloudhub worker New web client requests will RETURN AN ERROR until the NEW Cloudhub worker is available
• Cloudhub will redeploy the Mule application to a NEW Cloudhub worker New web client requests are ROUTED to the OLD Cloudhub worker until the NEW Cloudhub worker is available.
• Cloudhub will redeploy the mule application to the OLD Cloudhub worker New web client requests are ROUTED to the OLD Cloudhub worker BOTH before and after the Mule application is redeployed.
