Which concepts are a part of Pipeline Designer? Choose 3 answers.

  • A. Processor
  • B. Preparations
  • C. Connection
  • D. Dataset
  • E. Context variables

Answer: A,C,D

Explanation:
Comprehensive and Detailed Explanation:
Talend's Pipeline Designer is a tool that enables users to design and execute data integration workflows. Key components of Pipeline Designer include:
* Connection (Option C):
* Defines the link between Pipeline Designer and various data sources or destinations, specifying how to access and interact with external systems.
* Dataset (Option D):
* Represents the structured data that flows through the pipeline, serving as the input or output of various processing steps.
* Processor (Option E):
* Performs specific operations on the data within the pipeline, such as transformations, aggregations, or filtering, to achieve the desired data processing outcomes.
Why not other options?
* Option A:While context variables are used in Talend Studio for parameterizing jobs, they are not a primary concept in Pipeline Designer.
* Option B:"Preparations" refer to data transformation sequences in Talend Data Preparation, not directly in Pipeline Designer.


NEW QUESTION # 27
You need a list of all customers whose first name contains "Tom" and who are older than 18. Which processor should be used?

  • A. Data sampling
  • B. Filter
  • C. Join
  • D. Aggregate

Answer: B

Explanation:
Comprehensive and Detailed Explanation:
To filter customer records based onfirst name containing "Tom"andage greater than 18, theFilter processor is the correct choice.
* TheFilter processorallows users to setconditional rulesto extract only the required data.
* Users can specify conditions such as:
first_name CONTAINS "Tom"
AND
age > 18
* This ensures that only relevant records are included in the output.
Why not other options?
* Option A (Join):Used to combine data from multiple datasets based on a key field, not for filtering.
* Option B (Aggregate):Used for summarizing data, such as calculating counts, sums, or averages.
* Option D (Data Sampling):Used to select a random subset of data, not for filtering based on conditions.


NEW QUESTION # 28
User A shared a connection with User B. User B used the shared connection and created Dataset_1. User A stops sharing the connection with User B. Which statement is true about access to Dataset_1?

  • A. User B has no access to Dataset_1.
  • B. User A has full access to Dataset_1.
  • C. User B has limited access to Dataset_1.
  • D. User B has full access to Dataset_1.

Answer: D

Explanation:
Comprehensive and Detailed Explanation:
In Talend Cloud Data Inventory, when a user creates a dataset using a shared connection, the following applies:
* User B has full access to Dataset_1 (Option D):
* Once User B creates Dataset_1 using the shared connection, they become the owner of that dataset. Even if User A later revokes access to the connection, User B retains full access to Dataset_1. The dataset's accessibility is independent of the connection's sharing status after its creation.
Why not other options?
* Option A:User B's access to Dataset_1 is not limited; they have full ownership and control.
* Option B:Revoking the connection does not remove User B's access to datasets they have already created.
* Option C:User A's access to Dataset_1 depends on the sharing settings applied by User B; by default, User A does not have access unless granted.


NEW QUESTION # 29
You have two branches: Branch1 contains Job1, and Branch 2 contains Job 2. You want to copy Job1 to Branch 2 and preserve the change history when connecting Studio to Talend Administrator Center.
Which method should you use to preserve the change history?

  • A. Switch to Branch 1, copy lob 1, switch to Branch 2, and paste Job 1 over Job 2.
  • B. Switch to Branch 1, right-click Job 1, select Copy to branch, and select Branch 2.
  • C. Switch to branch 1, copy the Branch 1 Job, switch to Branch 2, and paste the Job into Branch 2.
  • D. Switch to Branch 1, copy the Branch 1 job, switch to Branch 2, and paste the job into Branch 2.

Answer: B

Explanation:
To copy Job1 from Branch1 to Branch2 and preserve the change history when connecting Studio to Talend Administration Center, you need to use the Copy to branch option. This option allows you to copy a job or a folder from one branch to another branch in the same project without losing the version history. You can access this option by switching to Branch1, right-clicking on Job1 in the Repository tree view, and selecting Copy to branch. This will open a dialog box where you can select Branch2 as the target branch and confirm the copy operation.
You do not need to use the import items, create standard job, or paste over options. These options are not used to copy jobs between branches and preserve the change history. 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 paste over option is used to overwrite an existing job with another job that has been copied or cut from the same or another project.
