B. Frequency
C. Lifetime

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 This helps manage storage and ensures that outdated metrics are purged.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.

A. Select the settings for a pipeline export.
B. Modify processor values.
C. Preview changes made by processors.
D. Display and update dataset connections.

Answer: B,D

Explanation:
Comprehensive and Detailed Explanation:
In Talend Pipeline Designer, theconfiguration panelprovides options for managing and modifying the settings of components within a pipeline.
* Modify processor values (Option A):
* Users can adjust values for processors such as filters, joins, transformations, and aggregations within the configuration panel.
* This helps fine-tune data processing rules directly in the pipeline.
* Display and update dataset connections (Option B):
* The configuration panel allows users to change dataset connections, updating the source or target locations of data.
* Users can modify database credentials, file paths, or API endpoints as needed.
Why not other options?
* Option C:The ability to preview changes made by processors is handled in thepreview panel, not the configuration panel.
* Option D:Pipeline export settings are managed separately in theexport settings menu, not in the configuration panel.

NEW QUESTION # 27
Which statements are true about the execution logs of a task running on a Remote Engine? Choose 2 answers.

A. Logs are stored in the file system of the server where the Remote Engine is running.
B. Logs are stored in Parquet format on the server where the Remote Engine is running.
C. Logs are stored in an H2 database hosted on the server where the Remote Engine is running.
D. Logs can be downloaded from Talend Management Console.

Answer: A,D

Explanation:
Comprehensive and Detailed Explanation:
When a task executes on a Talend Remote Engine, the execution logs are handled as follows:
* Logs are stored in the file system of the server where the Remote Engine is running (Option A):
* The Remote Engine writes execution logs to its local file system, typically in plain text or log formats. These logs provide detailed information about the task's execution and are essential for troubleshooting and monitoring.
* Logs can be downloaded from Talend Management Console (Option C):
* Talend Management Console (TMC) aggregates execution logs from Remote Engines, allowing users to access and download them directly through the TMC interface. This centralized access simplifies monitoring and debugging across multiple environments.
Why not other options?
* Option B:While some components of Talend may use H2 databases for internal purposes, execution logs are not typically stored in an H2 database on the Remote Engine server.
* Option D:Execution logs are generally stored in plain text or standard log formats, not in Parquet format. Parquet is a columnar storage file format commonly used for efficient data processing, not for logging purposes.

NEW QUESTION # 28
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. Navigate to Metadata, @ project ref, Job Designs, Standard, then select testJob.
C. Navigate to @ Referenced project, @ project_ref, Job Designs, Standard, then select testJob.
D. Right-click Job Designs, click Crete Standard Job, and enter testJob as the Job name.

Answer: C

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.).

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

Answer: A

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.
