  • B. Add ratings to the dataset
  • C. Use the dataset in an ETL Job
  • D. Change the dataset score manually

Answer: A,B

Explanation:
Comprehensive and Detailed Explanation:
To enhance the Trust Score of a dataset:
* Improve the quality of the dataset using Pipeline Designer (Option A):
* Utilizing Talend's Pipeline Designer allows you to cleanse, transform, and enrich your data, thereby improving its quality and, consequently, its Trust Score.
* Add ratings to the dataset (Option D):
* Encouraging users to rate the dataset increases its popularity metric, positively impacting the overall Trust Score.
Why not other options?
* Option B: The Trust Score is automatically calculated based on specific metrics; it cannot be manually altered.
* Option C: While using the dataset in ETL jobs indicates its utility, it does not directly influence the Trust Score unless it affects metrics like usage or popularity.


NEW QUESTION # 53
In Talend Studio, you have access to a references project named project_ref. You need to reuse a Job named testJob from the project_ref in your main Job.

  • A. Right-click Job Designs and click import items.
  • B. Right-click Job Designs, click Crete Standard Job, and enter testJob as the Job name.
  • C. Navigate to Metadata, @ project ref, Job Designs, Standard, then select testJob.
  • D. Navigate to @ Referenced project, @ project_ref, Job Designs, Standard, then select testJob.

Answer: D

Explanation:
To reuse a job named testJob from a referenced project named project_ref in your main job, you need to navigate to @Referenced project, @project_ref, Job Designs, Standard, then select testJob. A referenced project is a project that can be accessed from another project in read-only mode. You can add a referenced project to your main project by using the Project Settings window in Talend Studio. You can then browse the items (such as jobs, metadata, routines, etc.) of the referenced project in the Repository tree view under the
@Referenced project node. You can drag and drop any item from the referenced project to your main job design workspace.
You do not need to use import items, create standard job, or navigate to Metadata options. These options are not used to reuse jobs from referenced projects. The import items option is used to import items (such as jobs, metadata, routines, etc.) from an archive file that can be exported from another project or workspace. The create standard job option is used to create a new job with a name and a description. The Metadata node in the Repository tree view is used to store and manage metadata definitions for various data sources (such as databases, files, web services,etc.).

NEW QUESTION # 54
Which statements are true when comparing a Joblet to a tRunJob component?
Choose 3 answers

  • A. The nested Job called by a tRunJob component cannot use the same context variable of the Job in which it is used.
  • B. Building a Joblet typically requires the use of generic input, and trigger component.
  • C. A Joblet uses the same context variables of the Job in which it is used, unlinke a tRunJob component.
  • D. The performance of a Joblet if better than running an equivalent Job using a tRunJob component.
  • E. The performance of tRunJob component is better than running an equivalent Job using a Joblet.

Answer: A,B,C

Explanation:
A Joblet is a reusable piece of a job that can be used in multiple jobs as a single component. A tRunJob component is a component that allows you to call another job as a subjob within a parent job. When comparing a Joblet to a tRunJob component, these statements are true:
* A Joblet uses the same context variables of the job in which it is used, unlike a tRunJob component. A context variable is a variable that can store a value that can be changed at runtime or between different contexts. A Joblet inherits the context variables from the job that contains it and does not have its own context variables. A tRunJob component can pass context variables from the parent job to the child job, or use a specific context for the child job.
* Building a Joblet typically requires the use of generic input and trigger components. A Joblet can have one or more input and output flows that connect it with other components in a job. To create these flows, you need to use generic input and trigger components, such as tJobletInput, tJobletOutput, tJobletTriggerInput, and tJobletTriggerOutput. These components allow you todefine schemas and triggers for your Joblet without depending on specific components.
* The nested job called by a tRunJob component cannot use the same context variables of the job in which it is used. A nested job is a job that is called by another job using a tRunJob component. A nested job can have its own context variables or receive context variables from its parent job, but it cannot use the same context variables as its parent job. This means that if you have two context variables with the same name in both jobs, they will be treated as separate variables and will not share values.
These statements are false when comparing a Joblet to a tRunJob component:
* The performance of tRunJob component is better than running an equivalent job using a Joblet. The performance of a Joblet is better than running an equivalent job using a tRunJob component. This is because a Joblet is integrated into the main code of the job and does not require launching another JVM process or loading another metadata object like a tRunJob component does.

Which API definitions are supported by tRESTRequest?

  • A. CSV definition file
  • B. XML definition file
  • C. WSDL file
  • D. OAS/Swagger 2.0 file

Answer: D

Explanation:
Comprehensive and Detailed Explanation:
ThetRESTRequest componentsupportsOpenAPI Specification (OAS)/Swagger 2.0for initializing component endpoints, API mappings, and documentation.
* OAS/Swagger 2.0 file (Correct Answer - Option D):
* tRESTRequest allows API-first development by importing aSwagger 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.


NEW QUESTION # 56

  • B. Select the artifact name, add and configure a task, then run the task.
  • C. Select the corresponding task, configure the task, and then run the task.
  • D. Add a task and then run the task.

Answer: B,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 theManagementsection and selectTasks.
* Click onAdd 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 theArtifactssection to view your published Jobs.
* Select the desired artifact and click onAdd 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.
