Mulesoft MCD-LEVEL1 Online Questions & Answers

• Question 101:

  Refer to the exhibit.

  

  The API needs to be updated using the company-wide standard for the Plan data type. The Object data type has already been published in Anypoint Exchange with the global reference . ACME/DataTypes/PlanDataType.raml. What is a valid RAML specification that reuses the Plan data type?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  D. Option D

  ---

  Explanation/Reference:

  As can be seen in RAML, POST expects input in application/json format which eliminates two of the options as two options are in xml format. Now out of the two remaining options, one has id field in request which is only mentioned for get

  response and not for POST request. Hence id field is not expected in POST request.

  Hence correct answer is

  {

  "name": "GoerdiLa Forge",

  "address": "1 Westland CA",

  "customer_since": "2014-01-04",

  "balance": "4829.29",

  "bank_agend_id": "12556"

  }

• Question 102:

  Refer to exhibits.

  

  In the execution of the Scatter-Gather , the flow route completes after 10 seconds and the flow2 route completes in 40 seconds. How many seconds does it take for the Scatter- Gather to complete?

  A. 10
  B. 50
  C. 40
  D. 20
  C. 40

  ---

  Explanation/Reference:

  Scatter-Gather sends the event to each routes concurrently. Hence both route in this example will start in parallel. So total time to complete processing is 40 seconds which is option 3

• Question 103:

  Following Mulesoft's recommended API-led connectivity approach , an organization has created an application network. The organization now needs to create API's to transform , orchestrate and aggregate the data provided by the other API's in the application network. This API should be flexible enought ot handle the data from additional API's in future.

  According to Mulesoft's recommended API-led connectivity approach , what is the best layer for this new API?

  A. Process layer
  B. System layer
  C. Experience layer
  D. Data layer
  A. Process layer

  ---

  Explanation/Reference:

  Correct answer is process layer as all the orchestration and transformation logic should be in process layer as per Mulesoft's recommended approach for API led connectivity.

• Question 104:

  An organization's Center for enablement (C4E)has built foundational assets (API specifications and implementation templates, common frameworks, and best practices guides) and published them to Anypoint Exchange.

  What is a metric related to these foundational assets that helps the organization measure the success of it's C4E efforts?

  A. Utilization counts of foundational assets in production applications
  B. Correlation of each foundational asset with the counts of developers that download such asset
  C. Correlation of key performance indicators (KPI) of production applications with foundational assets
  D. Count how many Lines Of Business (LoBs) onsumed each foundational asset
  C. Correlation of key performance indicators (KPI) of production applications with foundational assets

  ---

  Explanation/Reference:

  Below are the Key performance indicators (KPIs), to measure and track the and success of the C4E and its activities, as well as the growth and health of the application network. Most of the metrics can be extracted automatically, through REST APIs, from Anypoint Platform.

  1.

  # of assets published to Anypoint Exchange

  2.

  # of interactions with Anypoint Exchange assets

  3.

  # of APIs managed by Anypoint Platform

  4.

  # of System APIs managed by Anypoint Platform

  5.

  # of API clients registered for access to APIs

  6.

  # of API implementations deployed to Anypoint Platform

  7.

  # of API invocations

  8.

  # or fraction of lines of code covered by automated tests in CI/CD pipeline

  9.

  Ratio of info/warning/critical alerts to number of API invocations

• Question 105:

  There are three routes configured for Scatter-Gather and incoming event has a payload is an Array of three objects. How routing will take place in this scenario?

  A. Incoming array objects would be split into three and each part would be sent to one route each in sequential manner
  B. Incoming array objects would be split into three and each part would be sent to one route each in parallel
  C. Entire event would be sent to each route sequentially
  D. Entire event would be sent to each route in parallel
  D. Entire event would be sent to each route in parallel

  ---

  Explanation/Reference:

  Entire event would be sent to each route in parallel. Scatter-Gather works as follows :

  -

  The Scatter-Gather component receives a Mule event and sends a reference of this Mule event to each processing route.

  -

  Each of the processing routes starts executing in parallel. After all processors inside a route finish processing, the route returns a Mule event, which can be either the same Mule event without modifications or a new Mule event created by the processors in the route as a result of the modifications applied.

  -

  After all processing routes have finished execution, the Scatter-Gather component creates a new Mule event that combines all resulting Mule events from each route, and then passes the new Mule event to the next component in the flow.

  

• Question 106:

  What valid RAML retrieves details on a specific by its orderld as a URL parameter?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A

• Question 107:

  Refer to the exhibit.

  

  What is the correct syntax to add an employee ID as a URI parameter in an HTTP Listener path?

  A. (employeelD)
  B. ${emp!oyeelD}
  C. {employeelD}
  D. # [employeelD]
  C. {employeelD}

  ---

  Explanation/Reference:

  While configuring HTTP listener path , URI parameters are always enclosed within curly braces. Hence option 2 is correct choice

• Question 108:

  Refer to the exhibits. A database Address table contains a ZIPCODE column and an increasing ID column. The Address table currently contains four (4) records. The On Table Row Database listener is configured with its watermark set to the Address table's ZIPCODE column and then the Mule application is run in Anypoint Studio for the first time, and the On Table Row Database listener polls the Address table.

  

  A new row is added to the database with ID=5 and ZIPCODE=90006, and then the On Table Row Database listener polls the database again.

  After the next execution of the On Table Row Database listener polling, what database rows have been processed by the Mule flow since the Mule application was started?

  A. ID ZIPCODE 1 90001 2 90005 3 90009 4 90001
  B. ID ZIPCODE 1 90001 2 90005 3 90009 4 90001 5 90006
  C. ID ZIPCODE 1 90001 2 90005 3 90009
  D. ID ZIPCODE 1 90001 2 90005 3 90009 5 90006
  A. ID ZIPCODE 1 90001 2 90005 3 90009 4 90001

  What is the valid properties placeholder file to set these values?

  

  A. 1.http: 2. host = "localhost" 3. port = "8081"
  B. 1.http: 2. basepath: "api" 3. host : "localhost" 4. port : "8081" (Correct)
  C. 1. http.host = localhost 2. http.port = 8081
  D. 1. { 2. http: 3. basePath: "api", 4. port: "8081", 5. host: " localhost"
  B. 1.http: 2. basepath: "api" 3. host : "localhost" 4. port : "8081" (Correct)

  ---
