Talend Core Certified Developer Exam Sample Questions (Q48-Q53):

NEW QUESTION # 48
Which HTTP methods are supported by tRESTRequest?

A. GET, POST, UPDATE, and DELETE
B. POST, PATCH, and UPDATE
C. GET, POST, PUT, PATCH, and DELETE
D. SELECT, INSERT, UPDATE, and DELETE

Answer: C

Explanation:
Comprehensive and Detailed Explanation:
The tRESTRequest component in Talend Studio is designed to handle RESTful web service requests. It supports the following HTTP methods:
* GET: Retrieves data from the server.
* POST: Submits data to the server, often causing a change in state or side effects.
* PUT: Replaces all current representations of the target resource with the request payload.
* PATCH: Applies partial modifications to a resource.
* DELETE: Removes the specified resource from the server.
Therefore, the correct answer isA. GET, POST, PUT, PATCH, and DELETE.

NEW QUESTION # 49
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 full access to Dataset_1.
B. User B has no access to Dataset_1.
C. User A has full access to Dataset_1.
D. User B has limited access to Dataset_1.

Answer: A

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 # 50
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 next component in the Job.
B. Confirm that you want to apply the schema changes to the previous 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: A

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 # 52
Which capabilities does Traces Debug provide?
Choose 2 answers

A. Filtering which data is propagated by a flow
B. Breaking when an input column fulfills a condition
C. Advancing one column at a time
D. Advancing one row at a time
E. Breaking on a selected line of code

Answer: B,D

Explanation:
Trace Debug mode is a feature that allows you to trace each row processed by your job components and see the values of each column in each row. You can access this mode by opening the Debug Run tab of the Run view and clicking on Trace Debug button.
The capabilities that Trace Debug mode provides are:
* Breaking when an input column fulfills a condition. You can set breakpoints on traces based on a condition or an expression that involves input data columns. For example, you can set a breakpoint to pause your job when a customer name contains a certain string or when a product price exceeds a certain value. To set a breakpoint based on a condition, you need to right-click on a trace on your jobdesign workspace and select Show Breakpoint Setup option. This will open a dialog box where you can enter a condition or an expression for your breakpoint.
* Advancing one row at a time. You can advance the execution of your job one row at a time by using the Step Over button in the toolbar of the Run view. This will allow you to see how each row is processed by your job components and how it affects the output data.
The capabilities that Trace Debug mode does not provide are:
* Filtering which data is propagated by a flow. You cannot filter which data is propagated by a flow in Trace Debug mode. A flow is a link that shows the data transfer between components in your job design workspace. In Trace Debug mode, you can see the data flow on each trace and inspect the values of each column for each row processed by your job. However, you cannot change which rows are propagated by a flow based on a condition or an expression.
* Advancing one column at a time. You cannot advance the execution of your job one column at a time in Trace Debug mode. You can only advance the execution of your job one row at a time by using the Step Over button in the toolbar of the Run view. This will allow you to see how each row is processed by your job components and how it affects the output data. However, you cannot see how each column is processed by your job components and how it affects the output data.
* Breaking on a selected line of code. You cannot break on a selected line of code in Trace Debug mode.
You can only break on a trace based on a condition or an expression that involves input data columns.
To break on a selected line of code, you need to use Java Debug mode. Java Debug mode allows you to debug your job code in Java or Perl and see the values of each variable or expression in your code. You can access this mode by switching to the Java perspective and clicking on the Debug button in the toolbar of the Code view.
