  A. Building MUnit tests so administrators can confirm code coverage percentage during deployment
  B. Publishing the fully implemented API to Exchange so all developers can reuse the API
  C. Adding global policies to the API so all developers automatically secure the implementation before coding anything
  D. Developing a specification so consumers can test before the implementation is built
  D. Developing a specification so consumers can test before the implementation is built

• Question 194:

  An auto mobile company want to share inventory updates with dealers Dl and D2 asynchronously and concurrently via queues Q1 and Q2. Dealer Dl must consume the message from the queue Q1 and dealer D2 to must consume a message from the queue Q2.

  Dealer D1 has implemented a retry mechanism to reprocess the transaction in case of any errors while processing the inventers updates. Dealer D2 has not implemented any retry mechanism.

  How should the dealers acknowledge the message to avoid message loss and minimize impact on the current implementation?

  A. Dealer D1 must use auto acknowledgement and dealer D2 can use manual acknowledgement and acknowledge the message after successful processing
  B. Dealer D1 can use auto acknowledgement and dealer D2 can use IMMEDIATE acknowledgement and acknowledge the message of successful processing
  C. Dealer D1 and dealer D2 must use AUTO acknowledgement and acknowledge the message after successful processing
  D. Dealer D1 can use AUTO acknowledgement and dealer D2 must use manual acknowledgement and acknowledge the message after successful processing
  D. Dealer D1 can use AUTO acknowledgement and dealer D2 must use manual acknowledgement and acknowledge the message after successful processing

• Question 195:

  As an enterprise architect, what are the two reasons for which you would use a canonical data model in the new integration project using Mulesoft Anypoint platform ( choose two answers )

  A. To have consistent data structure aligned in processes
  B. To isolate areas within a bounded context
  C. To incorporate industry standard data formats
  D. There are multiple canonical definitions of each data type
  E. Because the model isolates the back and systems and support mule applications from change
  A. To have consistent data structure aligned in processes
  B. To isolate areas within a bounded context

• Question 196:

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

  A. Anypoint Exchange
  B. API Manager
  C. Anypoint Studio
  D. Design Center
  A. Anypoint Exchange

• Question 197:

  An external REST client periodically sends an array of records in a single POST request to a Mule application API endpoint.

  The Mule application must validate each record of the request against a JSON schema before sending it to a downstream system in the same order that it was received in the array

  Record processing will take place inside a router or scope that calls a child flow. The child flow has its own error handling defined. Any validation or communication failures should not prevent further processing of the remaining records.

  To best address these requirements what is the most idiomatic(used for it intended purpose) router or scope to used in the parent flow, and what type of error handler should be used in the child flow?

  A. First Successful router in the parent flow On Error Continue error handler in the child flow
  B. For Each scope in the parent flow On Error Continue error handler in the child flow
  C. Parallel For Each scope in the parent flow On Error Propagate error handler in the child flow
  D. Until Successful router in the parent flow On Error Propagate error handler in the child flow
  B. For Each scope in the parent flow On Error Continue error handler in the child flow

  ---

  Correct answer is For Each scope in the parent flow On Error Continue error handler in the child flow. You can extract below set of requirements from the question a) Records should be sent to downstream system in the same order that it was received in the array b) Any validation or communication failures should not prevent further processing of the remaining records First requirement can be met using For Each scope in the parent flow and second requirement can be met using On Error Continue scope in child flow so that error will be suppressed.

• Question 198:

  What metrics about API invocations are available for visualization in custom charts using Anypoint Analytics?

  A. Request size, request HTTP verbs, response time
  B. Request size, number of requests, JDBC Select operation result set size
  C. Request size, number of requests, response size, response time
  D. Request size, number of requests, JDBC Select operation response time
  C. Request size, number of requests, response size, response time

  ---

  Correct answer is Request size, number of requests, response size, response time Analytics API Analytics can provide insight into how your APIs are being used and how they are performing. From API Manager, you can access the Analytics dashboard, create a custom dashboard, create and manage charts, and create reports. From API Manager, you can get following types of analytics: - API viewing analytics - API events analytics - Charted metrics in API Manager It can be accessed using: http://anypoint.mulesoft.com/analytics API Analytics provides a summary in chart form of requests, top apps, and latency for a particular duration.

  The custom dashboard in Anypoint Analytics contains a set of charts for a single API or for all APIs Each chart displays various API characteristics ?Requests size: Line chart representing size of requests in KBs ?Requests : Line chart representing number of requests over a period ?Response size : Line chart representing size of response in KBs ?Response time :Line chart representing response time in ms

  To check this, You can go to API Manager > Analytics > Custom Dashboard > Edit Dashboard > Create Chart > Metric

  

  https://docs.mulesoft.com/monitoring/api-analytics-dashboard

  Additional Information:

  The default dashboard contains a set of charts

  Requests by date: Line chart representing number of requests

  Requests by location: Map chart showing the number of requests for each country of origin

  Requests by application: Bar chart showing the number of requests from each of the top five registered applications

  Requests by platform: Ring chart showing the number of requests broken down by platform

• Question 199:

  A Mule application is built to support a local transaction for a series of operations on a single database. The mule application has a Scatter-Gather scope that participates in the local transaction.

  What is the behavior of the Scatter-Gather when running within this local transaction?

  A. Execution of all routes within Scatter-Gather occurs in parallel Any error that occurs inside Scatter-Gather will result in a roll back of all the database operations
  B. Execution of all routes within Scatter-Gather occurs sequentially Any error that occurs inside Scatter-Gather will be handled by error handler and will not result in roll back
  C. Execution of all routes within Scatter-Gather occurs sequentially Any error that occurs inside Scatter-Gather will result in a roll back of all the database operations
  D. Execution of all routes within Scatter-Gather occurs in parallel Any error that occurs inside Scatter-Gather will be handled by error handler and will not result in roll back
  A. Execution of all routes within Scatter-Gather occurs in parallel Any error that occurs inside Scatter-Gather will result in a roll back of all the database operations

• Question 200:

  What is required before an API implemented using the components of Anypoint Platform can be managed and governed (by applying API policies) on Anypoint Platform?

  A. The API must be published to Anypoint Exchange and a corresponding API instance ID must be obtained from API Manager to be used in the API implementation
  B. The API implementation source code must be committed to a source control management system (such as GitHub)
  C. A RAML definition of the API must be created in API designer so it can then be published to Anypoint Exchange
  D. The API must be shared with the potential developers through an API portal so API consumers can interact with the API
  A. The API must be published to Anypoint Exchange and a corresponding API instance ID must be obtained from API Manager to be used in the API implementation

  ---

  Context of the question is about managing and governing mule applications deployed on Anypoint platform.

  Anypoint API Manager (API Manager) is a component of Anypoint Platform that enables you to manage, govern, and secure APIs. It leverages the runtime capabilities of API Gateway and Anypoint Service Mesh, both of which enforce policies, collect and track analytics data, manage proxies, provide encryption and authentication, and manage applications.
