• Question 61:

  The asset version 2. 0.0 of the Order API is successfully published in Exchange and configured in API Manager with the Autodiscovery API ID correctly linked to the API implementation, A new GET method is added to the existing API specification, and after updates, the asset version of the Order API is 2. 0.1,

  What happens to the Autodiscovery API ID when the new asset version is updated in API Manager?

  A. The API ID changes, but no changes are needed to the API implementation for the new asset version in the API Autediscovery global element because the API ID is automatically updated
  B. The APL ID changes, so the API implementation must be updated with the latest API ID for the new asset version in the API Autodiscovery global element
  C. The APLID does not change, so no changes to the APT implementation are needed for the new asset version in the API Autodiscovery global element
  D. The APL ID does not change, but the API implementation must be updated in the AP] Autodiscovery global element to indicate the new asset version 2. 0.4
  C. The APLID does not change, so no changes to the APT implementation are needed for the new asset version in the API Autodiscovery global element

• Question 62:

  What correctly characterizes unit tests of Mule applications?

  A. They test the validity of input and output of source and target systems
  B. They must be run in a unit testing environment with dedicated Mule runtimes for the environment
  C. They must be triggered by an external client tool or event source
  D. They are typically written using MUnit to run in an embedded Mule runtime that does not require external connectivity
  D. They are typically written using MUnit to run in an embedded Mule runtime that does not require external connectivity

  ---

  Explanation

  Below TWO are characteristics of Integration Tests but NOT unit tests:

  They test the validity of input and output of source and target systems.

  They must be triggered by an external client tool or event source.

  It is NOT TRUE that Unit Tests must be run in a unit testing environment with dedicated Mule runtimes for the environment.

  MuleSoft offers MUnit for writing Unit Tests and they run in an embedded Mule Runtime without needing any separate/ dedicated Runtimes to execute them. They also do NOT need any external connectivity as MUnit supports mocking via

  stubs.

• Question 63:

  A REST API is being designed to implement a Mule application.

  What standard interface definition language can be used to define REST APIs?

  A. Web Service Definition Language(WSDL)
  B. OpenAPI Specification (OAS)
  C. YAML
  D. AsyncAPI Specification
  B. OpenAPI Specification (OAS)

  Explanation

• Question 64:

  An API with multiple API implementations (Mule applications) is deployed to both CloudHub and customer-hosted Mule runtimes. All the deployments are managed by the MuleSoft-hosted control plane. An alert needs to be triggered whenever an API implementation stops responding to API requests, even if no API clients have called the API implementation for some time.

  What is the most effective out-of-the-box solution to create these alerts to monitor the API implementations?

  A. Create monitors in Anypoint Functional Monitoring for the API implementations, where each monitor repeatedly invokes an API implementation endpoint
  B. Add code to each API client to send an Anypoint Platform REST API request to generate a custom alert in Anypoint Platform when an API invocation times out
  C. Handle API invocation exceptions within the calling API client and raise an alert from that API client when such an exception is thrown
  D. Configure one Worker Not Responding alert.in Anypoint Runtime Manager for all API implementations that will then monitor every API implementation
  A. Create monitors in Anypoint Functional Monitoring for the API implementations, where each monitor repeatedly invokes an API implementation endpoint

• Question 66:

  An API experiences a high rate of client requests (TPS) vwth small message paytoads. How can usage limits be imposed on the API based on the type of client application?

  A. Use an SLA-based rate limiting policy and assign a client application to a matching SLA tier based on its type
  B. Use a spike control policy that limits the number of requests for each client application type
  C. Use a cross-origin resource sharing (CORS) policy to limit resource sharing between client applications, configured by the client application type
  D. Use a rate limiting policy and a client ID enforcement policy, each configured by the client application type
  A. Use an SLA-based rate limiting policy and assign a client application to a matching SLA tier based on its type

  ---

  Explanation

  SLA tiers will come into play whenever any limits to be imposed on APIs based on client type

• Question 67:

  A customer has an ELA contract with MuleSoft. An API deployed to CloudHub is consistently experiencing performance issues. Based on the root cause analysis, it is determined that autoscaling needs to be applied.

  How can this be achieved?

  A. Configure a policy so that when the number of HTTP requests reaches a certain threshold the number of workers/replicas increases (horizontal scaling)
  B. Configure two separate policies: When CPU and memory reach certain threshold, increase the worker/replica type (vertical sealing) and the number of workers/replicas (horizontal sealing)
  C. Configure a policy based on CPU usage so that CloudHub auto-adjusts the number of workers/replicas (horizontal scaling)
  D. Configure a policy so that when the response time reaches a certain threshold the worker/replica type increases (vertical scaling)
  C. Configure a policy based on CPU usage so that CloudHub auto-adjusts the number of workers/replicas (horizontal scaling)

• Question 68:

  Which out-of-the-box key performance indicator measures the success of a typical Center for Enablement and is immediately available in responses from Anypoint Platform APIs?

  A. Per business group, the ratio of the number of production APT implementations deployed using a C1/CD pipeline to the number of production API implementations deployed manually
  B. Per deployed API implementation, the amount of bandwidth consumed each day
  C. Per published API, the number of developers that downloaded s version of the API specification
  D. Per published API, the number of consumers that requested access to the API and have been approved in the Production environment
  D. Per published API, the number of consumers that requested access to the API and have been approved in the Production environment

• Question 69:

  A company deployed an API to a single worker/replica in the shared cloud in the U.S. West Region.

  What happens when the Availability Zone experiences an outage?

  A. CloudHub will auto-redeploy the APL in the U.S. East Region
  B. The APT will be unavailable until the availability comes back online, at which time the worker/replica will be auto-restarted
  C. CloudHub will auto-redeploy the API in another Availability Zone in the U.S. West Region
  D. The Anypoint Platform admin is alerted when the AP] is experiencing an outage and needs the trigger the CI/CD pipeline to redeploy to the US. East Region
  B. The APT will be unavailable until the availability comes back online, at which time the worker/replica will be auto-restarted

• Question 70:

  What best describes the Fully Qualified Domain Names (FQDNs), also known as DNS entries, created when a Mule application is deployed to the CloudHub Shared Worker Cloud?

  A. A fixed number of FQDNs are created, IRRESPECTIVE of the environment and VPC design
  B. The FQDNs are determined by the application name chosen, IRRESPECTIVE of the region
  C. The FQDNs are determined by the application name, but can be modified by an administrator after deployment
  D. The FQDNs are determined by both the application name and the Anypoint Platform organization
  B. The FQDNs are determined by the application name chosen, IRRESPECTIVE of the region

  ---

  Explanation

  When deploying applications to Shared Worker Cloud, the FQDN are always determined by application name chosen.

  It does NOT matter what region the app is being deployed to.

  Although it is fact and true that the generated FQDN will have the region included in it (Ex:

  exp-salesorder-api.au-s1.cloudhub.io), it does NOT mean that the same name can be used when deploying to another CloudHub region.

  Application name should be universally unique irrespective of Region and Organization and solely determines the FQDN for Shared Load Balancers.
