Talend Core Certified Developer Exam Sample Questions (Q12-Q17):

NEW QUESTION # 12
Which aspects contribute to the calculation of the validity of a dataset? Choose 2 answers.

A. Number of empty rows across the dataset sample
B. Number of valid and invalid values across the dataset sample
C. Use of user ratings and certification
D. Use of semantic types across the dataset sample

Answer: B,D

Explanation:
Comprehensive and Detailed Explanation:
The validity of a dataset in Talend's Trust Score framework is determined by:
* Number of valid and invalid values across the dataset sample (Option B):
* This metric assesses the quality of the data by evaluating the proportion of valid entries compared to invalid ones. A higher number of valid values indicates better data quality.
* Use of semantic types across the dataset sample (Option C):
* Semantic types help in understanding the meaning and context of data fields. Consistent and correct application of semantic types ensures that data is interpreted accurately, contributing to its validity.
Why not other options?
* Option A: User ratings and certification pertain to the popularity axis, reflecting user trust and endorsement, not the intrinsic validity of the data.
* Option D: The number of empty rows relates to the completeness axis, indicating missing data, rather than directly affecting validity.

NEW QUESTION # 13
You want to improve the Trust Score of your dataset as a dataset owner. Which actions should you perform? Choose 2 answers.

A. Change the dataset score manually
B. Improve the quality of the dataset using Pipeline Designer
C. Use the dataset in an ETL Job
D. Add ratings to the dataset

Answer: B,D

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 # 14
Which action should you perform to calculate the overall Trust Score for multiple customer datasets?

A. Use the search bar to filter the customer datasets and manually calculate the score.
B. Review the rating of selected datasets in the group tab.
C. Use the search bar to filter the customer datasets, and the score will automatically update.
D. Mark the datasets in the dataset list, and the score updates in the detailed view.

Answer: C

Explanation:
Comprehensive and Detailed Explanation:
To calculate the overall Trust Score for multiple customer datasets:
* Use the search bar to filter the customer datasets, and the score will automatically update (Option B):
* Filtering datasets using the search functionality aggregates the Trust Scores of the selected datasets, providing an overall score for the group.
Why not other options?
* Option A: Reviewing individual ratings does not provide an aggregated Trust Score.
* Option C: Marking datasets does not trigger an automatic update of the aggregated score.
* Option D: Manual calculation is unnecessary as the system provides automatic aggregation upon filtering.

NEW QUESTION # 15
In some instances, after applying changes to a component schema, you are asked if you would like to propagate the changes. What is the significance of thisprompt?

A. Confirm that you want to apply the schema changes to the previous component in the Job.
B. Confirm that you want to apply the schema changes to the next component in the Job.
C. Confirm that you want to apply the schema changes to the selected component.
D. Confirm that you want to apply the schema changes to both the previous and next components in the Job.

Answer: B

Explanation:
When you modify the schema of a component in Talend Studio, the application prompts you to propagate these changes. This propagation ensures that any alterations to the data structure are consistently applied throughout the Job, maintaining data integrity and coherence.
Understanding Schema Propagation:
* Purpose:Schema propagation is essential to synchronize the data structure across connected components. When a schema changes (e.g., adding or removing a column), downstream components that rely on this schema need to be updated to reflect these changes.
* Prompt Significance:The prompt serves as a confirmation to apply the schema changes to the subsequent components in the Job. By agreeing to propagate, Talend Studio automatically updates the schemas of all downstream components connected to the modified component.
Example Scenario:
Consider a Job where a tFileInputDelimited component reads data and passes it to a tMap component, which then outputs to a tFileOutputDelimited component. If you add a new column to the schema of tFileInputDelimited:
* Modification:
* You add a new column, 'emailAddress', to the tFileInputDelimited schema.
* Propagation Prompt:
* Upon making this change, Talend Studio prompts you to propagate the schema changes.
* Effect of Propagation:
* By confirming, the 'emailAddress' column is added to the schemas of all downstream components (e.g., tMap and tFileOutputDelimited). This ensures that these components recognize and can process the new column appropriately.
By understanding and utilizing schema propagation, you ensure that all components within your Talend Jobs remain synchronized, reducing errors and enhancing data processing efficiency.

NEW QUESTION # 16
You want to create a generic schema using a schema defined in a Talend component in the Repository view.
How can you accomplish this?

A. In the Schema Editor window for the component.
B. On the Advanced settings tab of the Component view.
C. In the Repository, by right-clicking Generic schemas.
D. By right-clicking the component and selecting the Generic schema option.

Answer: C

Explanation:
To create a generic schema from a schema defined in a Talend component, follow these steps:
* Open the Repository View:
* In Talend Studio, navigate to the Repository panel, typically located on the left side of the interface.
* Locate the 'Generic schemas' Node:
* Within the Repository, expand the 'Metadata' section to find the 'Generic schemas' node.
* Initiate the Generic Schema Creation Process:
* Right-click on 'Generic schemas' and select 'Create generic schema' from the context menu.
* Define the Schema Properties:
* In the schema creation wizard that appears, provide the necessary properties such as 'Name' and
'Description' for the new generic schema.
* Set Up the Schema Structure:
* Define the schema structure by adding columns and specifying their data types as required.
* Finalize the Schema Creation:
* Click 'Finish' to complete the creation process. The new generic schema will now be available under the 'Generic schemas' node in the Repository.
This method allows you to create a reusable generic schema that can be applied across multiple components and Jobs within Talend Studio.
