• Question 101:

  What Mule application can have API policies applied by Anypoint Platform to the endpoint exposed by that Mule application?

  A. A Mule application that accepts requests over HTTP/1x
  B. A Mule application that accepts JSON requests over TCP but is NOT required to provide a response.
  C. A Mule application that accepts JSON requests over WebSocket
  D. A Mule application that accepts gRPC requests over HTTP/2
  A. A Mule application that accepts requests over HTTP/1x

  ---

  # HTTP/1.1 keeps all requests and responses in plain text format.

  # HTTP/2 uses the binary framing layer to encapsulate all messages in binary format, while still maintaining HTTP semantics, such as verbs, methods, and headers. It came into use in 2015, and offers several methods to decrease latency, especially when dealing with mobile platforms and server-intensive graphics and videos

  # Currently, Mule application can have API policies only for Mule application that accepts requests over HTTP/1x

• Question 102:

  A gaming company has implemented an API as a Mule application and deployed the API implementation to a CloudHub 2.0 private space. The API implementation must connect to a mainframe application running in the customer's on-premises corporate data center and also to a Kafka cluster running in an Amazon AWS VPC. What is the most efficient way to enable the API to securely connect from its private space to the mainframe application and Kafka cluster?

  

  A. In Runtime Manager, set up VPC peering between the CloudHub 2.0 private network and the on-premises data center. In the AWS account, set up VPC peering between the AWS VPC and the CloudHub 2.0 private network.
  B. In the AWS account, attach the CloudHub 2.0 private space to an AWS transit gateway that routes from the CloudHub 2.0 private space to the on-premises data center. In Runtime Manager, configure an Anypoint VPN to route from the CloudHub 2.0 private space to the AWS VPC.
  C. In Runtime Manager, configure an Anypoint VPN to route from the CloudHub 2.0 private space to the on-premises data center. In the AWS account, attach the private..
  D. In the AWS account, attach the private space directly to the AWS VPC, In the AWS account, use an AWS transit gateway to route from the AWS VPC to the on-premises data center.
  B. In the AWS account, attach the CloudHub 2.0 private space to an AWS transit gateway that routes from the CloudHub 2.0 private space to the on-premises data center. In Runtime Manager, configure an Anypoint VPN to route from the CloudHub 2.0 private space to the AWS VPC.

  ---

  To enable the API to securely connect from its CloudHub 2.0 private space to both the on-premises mainframe application and the Kafka cluster in an Amazon AWS VPC, the following approach is recommended:

  AWS Transit Gateway: In the AWS account, attach the CloudHub 2.0 private space to an AWS Transit Gateway. This gateway facilitates routing between the CloudHub private space and the on-premises data center.

  Routing to On-Premises: The AWS Transit Gateway will route traffic from the CloudHub 2.0 private space to the on-premises data center, enabling secure and efficient communication.

  Anypoint VPN: In MuleSoft Runtime Manager, configure an Anypoint VPN to establish a secure connection from the CloudHub 2.0 private space to the AWS VPC where the Kafka cluster is hosted. This VPN ensures encrypted and secure communication between CloudHub and AWS VPC.

  This method uses both AWS Transit Gateway and Anypoint VPN to create a secure and efficient network setup, allowing the API to connect to both on-premises and AWS resources.

  B. Reliance on an Integration-Platform-as-a-Service (iPaaS)
  C. Spending too much time on enablement
  D. Lack of alignment around business outcomes
  D. Lack of alignment around business outcomes

• Question 104:

  An organization has implemented a continuous integration (CI) lifecycle that promotes Mule applications through code, build, and test stages. To standardize the organization's CI journey, a new dependency control approach is being designed to store artifacts that include information such as dependencies, versioning, and build promotions.

  To implement these process improvements, the organization will now require developers to maintain all dependencies related to Mule application code in a shared location.

  What is the most idiomatic (used for its intended purpose) type of system the organization should use in a shared location to standardize all dependencies related to Mule application code?

  A. A MuleSoft-managed repository at repository.mulesoft.org
  B. A binary artifact repository
  C. API Community Manager
  D. The Anypoint Object Store service at cloudhub.io
  C. API Community Manager

• Question 105:

  Which Anypoint Platform component should a MuleSoft developer use to create an API specification prior to building the API implementation?

  A. MUnit
  B. API Designer
  C. API Manager
  D. Runtime Manager
  B. API Designer

• Question 106:

  Insurance organization is planning to deploy Mule application in MuleSoft Hosted runtime plane. As a part of requirement , application should be scalable . highly available. It also has regulatory requirement which demands logs to be retained for at least 2 years. As an Integration Architect what step you will recommend in order to achieve this?

  A. It is not possible to store logs for 2 years in CloudHub deployment. External log management system is required.
  B. When deploying an application to CloudHub , logs retention period should be selected as 2 years
  C. When deploying an application to CloudHub, worker size should be sufficient to store 2 years data
  D. Logging strategy should be configured accordingly in log4j file deployed with the application.
  A. It is not possible to store logs for 2 years in CloudHub deployment. External log management system is required.

  ---

  Correct answer is It is not possible to store logs for 2 years in CloudHub deployment. External log management system is required. CloudHub has a specific log retention policy, as described in the documentation: the platform stores logs of up to 100 MB per app and per worker or for up to 30 days, whichever limit is hit first. Once this limit has been reached, the oldest log information is deleted in chunks and is irretrievably lost. The recommended approach is to persist your logs to a external logging system of your choice (such as Splunk, for instance) using a log appender. Please note that this solution results in the logs no longer being stored on our platform, so any support cases you lodge will require for you to provide the appropriate logs for review and case resolution

• Question 107:

  A manufacturing company is planning to deploy Mule applications to its own Azure Kubernetes Service infrastructure.

  The organization wants to make the Mule applications more available and robust by deploying each Mule application to an isolated Mule runtime in a Docker container while managing all the Mule applications from the MuleSoft-hosted control plane.

  What is the most idiomatic (used for its intended purpose) choice of runtime plane to meet these organizational requirements?

  A. Anypoint Platform Private Cloud Edition
  B. Anypoint Runtime Fabric
  C. CloudHub
  D. Anypoint Service Mesh
  B. Anypoint Runtime Fabric

• Question 108:

  A retailer is designing a data exchange interface to be used by its suppliers. The interface must support secure communication over the public internet. The interface must also work with a wide variety of programming languages and IT systems used by suppliers. What are suitable interface technologies for this data exchange that are secure, cross- platform, and internet friendly, assuming that Anypoint Connectors exist for these interface technologies?

  A. EDJFACT XML over SFTP JSON/REST over HTTPS
  B. SOAP over HTTPS HOP over TLS gRPC over HTTPS
  C. XML over ActiveMQ XML over SFTP XML/REST over HTTPS
  D. CSV over FTP YAML over TLS JSON over HTTPS
  C. XML over ActiveMQ XML over SFTP XML/REST over HTTPS

  # As per definition of API by Mulesoft , it is Application Programming Interface using HTTP- based protocols. Non-HTTP-based programmatic interfaces are not APIs.

  # HTTP-based programmatic interfaces are APIs even if they don't use REST or JSON. Hence implementation based on Java RMI, CORBA/IIOP, raw TCP/IP interfaces are not API's as they are not using HTTP.

  # One more thing to note is FTP was not built to be secure. It is generally considered to be an insecure protocol because it relies on clear-text usernames and passwords for authentication and does not use encryption.

  # Data sent via FTP is vulnerable to sniffing, spoofing, and brute force attacks, among other basic attack methods. Considering the above points only correct option is -XML over ActiveMQ

  -XML over SFTP

  -XML/REST over HTTPS

• Question 109:

  How should the developer update the logging configuration in order to enable this package specific debugging?

  A. In Anypoint Monitoring, define a logging search query with class property set to org.apache.cxf and level set to DEBUG
  B. In the Mule application's log4j2.xml file, add an AsyncLogger element with name property set to org.apache.cxf and level set to DEBUG, then redeploy the Mule application in the CloudHub production environment
  C. In the Mule application's log4j2.xmI file, change the root logger's level property to DEBUG, then
  D. redeploy the Mule application to the CloudHub production environment
  E. In Anypoint Runtime Manager, in the Deployed Application Properties tab for the Mule application, add a line item with DEBUG level for package org.apache.cxf and apply the changes
  A. In Anypoint Monitoring, define a logging search query with class property set to org.apache.cxf and level set to DEBUG

  ---

  To enable package-specific debugging for the org.apache.cxf package, you need to update the logging configuration in the Mule application's log4j2.xml file. The steps are as follows:

  Open the log4j2.xml file in your Mule application.

  Add an AsyncLogger element with the name property set to org.apache.cxf and the level set to DEBUG . This configuration specifies that only the logs from the org.apache.cxf package should be logged at the DEBUG level.

  Save the changes to the log4j2.xml file.

  Redeploy the updated Mule application to the CloudHub production environment to apply the new logging configuration.

  This approach ensures that only the specified package's logging level is changed to DEBUG, minimizing the potential performance impact on the application.

• Question 110:

  A Mule application is running on a customer-hosted Mule runtime in an organization's network. The Mule application acts as a producer of asynchronous Mule events. Each Mule event must be broadcast to all interested external consumers outside the Mule application. The Mule events should be published in a way that is guaranteed in normal situations and also minimizes duplicate delivery in less frequent failure scenarios.

  The organizational firewall is configured to only allow outbound traffic on ports 80 and 443. Some external event consumers are within the organizational network, while others are located outside the firewall.

  What Anypoint Platform service is most idiomatic (used for its intended purpose) for publishing these Mule events to all external consumers while addressing the desired reliability goals?

  A. CloudHub VM queues
  B. Anypoint MQ
  C. Anypoint Exchange
  D. CloudHub Shared Load Balancer
  B. Anypoint MQ

  ---

  Set the Anypoint MQ connector operation to publish or consume messages, or to accept (ACK) or not accept (NACK) a message.
