How can you create REST API metadata in Talend Studio? Choose 2 answers.
A, B
Explanation:
Comprehensive and Detailed Explanation:
In Talend Studio, REST API metadata can be created using the following methods:
Create it manually in Talend Studio (Option A):
Users can define REST API metadata within Talend Studio by manually specifying API structure,
endpoints, HTTP methods, and parameters.
This method provides full control over the API metadata but requires manual configuration.
Import it from Talend API Designer (Option B):
If an API has been designed using Talend API Designer, it can be imported into Talend Studio.
This enables reusing the API design directly without manual recreation.
Why not other options?
Option C (Import from JSON file): Talend Studio does not support direct import of REST API metadata
from generic JSON files.
Option D (Import from Talend API Tester): Talend API Tester is used for testing APIs but does not
provide an option to import API definitions into Talend Studio.

What is the default port for the REST Endpoint when using tRESTRequest in Talend Studio?
D
Explanation:
Comprehensive and Detailed Explanation:
The default REST endpoint port for tRESTRequest in Talend Studio is 8090.
Port 8090 (Correct Answer - Option D):
When running a REST service inside Talend Studio, the default listening port is 8090.
This can be changed in the component settings if required.
Other port options explained:
5040 & 5070: Not default ports used for Talend REST services.
8040: Used in Talend Runtime, not in Studio.

You can initialize your component endpoint, API mappings, and documentation from your API
definition. Which API definitions are supported by tRESTRequest?
D
Explanation:
Comprehensive and Detailed Explanation:
The tRESTRequest component supports OpenAPI Specification (OAS)/Swagger 2.0 for initializing
component endpoints, API mappings, and documentation.
OAS/Swagger 2.0 file (Correct Answer - Option D):
tRESTRequest allows API-first development by importing a Swagger 2.0 (OAS) definition.
This enables automatic configuration of API endpoints, request parameters, and response structures.
Why not other options?
CSV definition file (Option A): Not a valid API definition format.
XML definition file (Option B): XML files are not standard for REST API definitions.
WSDL file (Option C): WSDL is used for SOAP-based web services, not REST.

Which HTTP methods are supported by tRESTRequest?
A
Explanation:
Comprehensive and Detailed Explanation:
The tRESTRequest component in Talend Studio is designed to handle RESTful web service requests. It
supports the following HTTP methods:
GET: Retrieves data from the server.
POST: Submits data to the server, often causing a change in state or side effects.
PUT: Replaces all current representations of the target resource with the request payload.
PATCH: Applies partial modifications to a resource.
DELETE: Removes the specified resource from the server.
Therefore, the correct answer is A. GET, POST, PUT, PATCH, and DELETE.

You are using a tRESTClient component to call a REST service. Which advanced option should you use
to convert the response from the server to the document type?
C
Explanation:
Comprehensive and Detailed Explanation:
In Talend Studio, the tRESTClient component includes an advanced setting called "Convert Response
To DOM Document". When this option is selected, the response from the REST service is converted
into a DOM (Document Object Model) document. This allows for structured processing of the
response data within Talend workflows.

Which component can be used to read a CSV file in an ESB Route?
C
Explanation:
Comprehensive and Detailed Explanation:
In Talend's Enterprise Service Bus (ESB) routes, the appropriate component to read a CSV file is
cFileInputDelimited. This component is specifically designed for Camel routes to handle delimited
files like CSVs.

After enabling the Observability Metric Collector metric generation located in the
\etc\org.talend.ipaas.rt.observability.cfg, which additional configurations should you apply? Choose
2 answers.
C, D
Explanation:
Comprehensive and Detailed Explanation:
After enabling the Observability Metric Collector in Talend's configuration file
(org.talend.ipaas.rt.observability.cfg), it's essential to set additional parameters to control the
behavior of metric collection:
Frequency (Option C): Determines how often metrics are collected. Setting this ensures that data is
gathered at appropriate intervals for monitoring needs.
Lifetime (Option D): Specifies how long the collected metrics are retained. This helps manage storage
and ensures that outdated metrics are purged.
Configuring these parameters ensures that the metric collection aligns with organizational
requirements for monitoring and performance analysis.

You implemented a Job in Talend Studio and need to execute it in Talend Cloud. Which options can
you use in Talend Management Console after publishing the Job to Talend Cloud? Choose 2 answers.
A, D
Explanation:
Comprehensive and Detailed Explanation:
After publishing a Job from Talend Studio to Talend Cloud, you can execute it using the Talend
Management Console (TMC) by following these steps:
Add a task and then run the task (Option A):
In TMC, navigate to the Management section and select Tasks.
Click on Add Task, choose the published artifact (your Job), configure necessary parameters, and save
the task.
Once the task is created, you can run it manually or schedule it for execution.
Select the artifact name, add and configure a task, then run the task (Option D):
In TMC, go to the Artifacts section to view your published Jobs.
Select the desired artifact and click on Add Task.
Configure the task settings as needed and save it.
After creating the task, you can execute it immediately or set up a schedule.
Why not other options?
Option B: TMC does not support directly running a Job by clicking on the artifact name without first
creating a task.
Option C: While you can select and configure an existing task, the initial step requires creating the
task associated with the artifact.

You created a Remote Engine in Talend Cloud and copied the Remote Engine key. You downloaded
the Remote Engine script for your Linux system, and now you need to pair the engine manually.
Which options can you use to set the key? Choose 2 answers.
B, C
Explanation:
Comprehensive and Detailed Explanation:
To manually pair a Remote Engine with Talend Cloud, you can set the pairing key using the following
methods:
In the Remote Engine web service page (Option B):
Access the Remote Engine's web interface, typically available at http://localhost:8043/configuration.
Enter the pairing key obtained from the Talend Management Console.
Click on PAIR REMOTE ENGINE to establish the connection.
In the key configuration file of the engine (Option C):
Locate the preauthorized.key.cfg file in the Remote Engine's etc directory.
Open the file and paste the pairing key into the remote.engine.pre.authorized.key parameter.
Save the changes and restart the Remote Engine to apply the configuration.
Why not other options?
Option A: Setting the pairing key in Talend Studio's preferences is not applicable for pairing a Remote
Engine.
Option D: While it's technically possible to pass the pairing key as a parameter in the engine's run
script, it's not the standard or recommended method.

Jobs (Option D): Standard data integration tasks designed in Talend Studio.
Big Data tasks (Option B): Tasks involving big data processing.
Routes (Option C): Tasks related to messaging routes.
However, Data services (Option A) refer to web services and are not typically added as tasks within a
plan.
