NEW QUESTION # 51
Which Action on table operations are supported by a tMysqlOutput component? Choose 3 answers.

  • A. Replace
  • B. Drop table
  • C. Create table if does not exist
  • D. Create table
  • E. Drop table if exists and create

Answer: C,D,E

Explanation:
Comprehensive and Detailed Explanation:
The tMysqlOutput component in Talend provides several actions on tables to manage data output operations effectively. The supported actions include:
* Drop Table if Exists and Create (Option B):
* This action checks if the specified table exists in the database. If it does, the table is dropped and a new one is created. This ensures that the table is recreated fresh for the data load.
* Create Table if Does Not Exist (Option D):
* This action checks if the specified table exists in the database. If it does not exist, the table is created. If it already exists, no action is taken, and the existing table is used.
* Create Table (Option E):
* This action attempts to create the specified table in the database. If the table already exists, an error will occur unless handled appropriately.
These actions provide flexibility in managing database tables during data integration processes, allowing for dynamic table creation and management based on the Job's requirements.

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

Answer: B,C

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
You need to call a different Job within a Job you are developing.
Which mechanism allows you to pass the parameters to the lob you want to call?

  • A. Context parameters
  • B. File
  • C. CommandLine options
  • D. Java Function paramters

Answer: A

Explanation:
To call a different job within a job you are developing, you can use the tRunJob component. This component allows you to execute another job as a subjob within a parent job. To pass the parameters to the job you want to call, you can use the context parameters. Context parameters are variables that can store values that can be changed at runtime or between different contexts. You can define context parameters in the Contexts tab of your job and assign them values for each context. You can also pass context parameters from the parent job to the child job by using the Context Param tab of the tRunJob component. This way, you can parameterize the properties or expressions of the child job with the values from the parent job.
You do not need to use a file, command line options, or Java function parameters to pass parameters to a different job. These methods are not supported by Talend Studio and may cause errors or unexpected results.
