NEW QUESTION # 51
An API implementation has been deployed to CloudHub and now needs to be governed. IT will not allocate additional vCore for a new Mule application to act as an API proxy.
What is the next step to preseive the current vCore usage, but still allow the Mule application to be managed by API Manager?
- A. Upload the Mule application's JAR file to the API instance in API Manager
- B. Register the same API implementation in Runtime Manager to connect to API Manager
- C. Modify the API implementation to use auto-discovery to register with API Manager
- D. Deploy the same API implementation behind a VPC and configure the VPC to connect to API Manager
Answer: C
Explanation:
Correct answer is Modify the API implementation to use auto-discovery to register with API Manager API Autodiscovery Configuring autodiscovery allows a deployed Mule runtime engine (Mule) application to connect with API Manager to download and manage policies and to generate analytics data. Additionally, with autodiscovery, you can configure your Mule applications to act as their own API proxy.
When autodiscovery is correctly configured in your Mule application, you can say that your application's API is tracked by (green dot) or paired to API Manager. You can associate an API in a Mule setup with only one autodiscovery instance at a given time.

NEW QUESTION # 57
A Scatter-Gather processes three separate HTTP requests. Each request returns a Mule event with a JSON payload. What is the final output of the Scatter-Gather?
- A. An Object containing all three Mule event Objects
- B. An Array of the three Mule event Objects
- C. An Object containing all three JSON payload Objects
- D. An Array of the three JSON payload Objects
Answer: A
Explanation:
Correct answer is An Object containing all three Mule event Objects
The Scatter-Gather component is a routing event processor that processes a Mule event through different parallel processing routes that contain different event processors. Each route receives a reference to the Mule event and executes a sequence of one or more event processors. Each of these routes uses a separate thread to execute the event processors, and the resulting Mule event can be either the same Mule event without modifications or a new Mule event with its own payload, attributes, and variables. The Scatter-Gather component then combines the Mule events returned by each processing route into a new Mule event that is passed to the next event processor only after every route completes successfully.
The Scatter-Gather component executes each route in parallel, not sequentially. Parallel execution of routes can greatly increase the efficiency of your Mule application and may provide more information than sequential processing.
Sample output is as below

- A. #[The city is ${payload.City}
- B. The city is #[payload.City]
- C. The city is + #[payload.City]
- D. #["The city is" ++ payload.City]
Answer: B

NEW QUESTION # 60
What is output of Dataweave flatten function?
- A. LInkedHashMap
- B. Array
- C. Map
- D. Object
Answer: B
Explanation:
Correct answer is Array.
Flatten turns a set of subarrays (such as [ [1,2,3], [4,5,[6]], [], [null] ]) into a single, flattened array (such as [ 1,
2, 3, 4, 5, [6], null ]).
This example defines three arrays of numbers, creates another array containing those three arrays, and then uses the flatten function to convert the array of arrays into a single array with all values.
Source
%dw 2.0
output application/json
var array1 = [1,2,3]
var array2 = [4,5,6]
var array3 = [7,8,9]
var arrayOfArrays = [array1, array2, array3]
---
flatten(arrayOfArrays)
Output
[ 1,2,3,4,5,6,7,8,9 ]
NEW QUESTION # 61

- A. 0
- B. 1
- C. 2
- D. 3
Answer: A

NEW QUESTION # 66
An API instance of type API endpoint with API proxy is created in API manager using an API specification from Anypoint Exchange. The API instance is also configured with an API proxy that is deployed and running in CloudHub.
An SLA- based policy is enabled in API manager for this API instance.
Where can an external API consumer obtain a valid client ID and client secret to successfully send requests to the API proxy?
- A. In Runtime Manager, from the properties tab of the deployed approved API proxy
- B. In Anypoint Studio, from components generated by APIkit for the API specification
- C. In the organization's public API portal in Anypoint Exchange, from an approved client application for the API proxy
- D. In Anypoint Studio, from components generated by Rest Connect for API specification
Answer: C
Explanation:
* When a client application is registered in Anypoint Platform, a pair of credentials consisting of a client ID and client secret is generated.
* When the client application requests access to an API, a contract is created between the application and that API.
* An API that is protected with a Client ID Enforcement policy is accessible only to applications that have an approved contract.
