  • C. Scales the Trust Score from 0 to 5.
  • D. Aggregates several metrics into a single score.

正解：C、D

解説：
Comprehensive and Detailed Explanation:
The Talend Trust Score is a feature of Talend Cloud Data Inventory that provides an assessment of a dataset's reliability and quality:
* Aggregates several metrics into a single score (Option A):
* The Trust Score combines multiple factors, including validity, completeness, popularity, discoverability, and usage, into a single, comprehensive score. This aggregation helps users quickly gauge the overall trustworthiness of a dataset.
* Scales the Trust Score from 0 to 5 (Option C):
* The Trust Score ranges from 0 to 5, with higher scores indicating better data quality and reliability. This standardized scale allows for easy comparison between datasets.
Why not other options?
* Option B:While data consumers can view and utilize the Trust Score, it is automatically calculated by Talend based on specific metrics; users do not assign this score themselves.
* Option D:The Trust Score does not use a 0 to 10 scale; it specifically ranges from 0 to 5.


質問 # 23
You create a Job consisting of two subJobs, A and B. You added Joblet C with the intension of running it between A and B.
What are the minimum requirements to orchestrate this? (Choose Two)

  • A. Link A, B and C using On Subject Ok triggers.
  • B. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into B.
  • C. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into C
  • D. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into A.

正解：A、C

解説：
To create a job consisting of two subjobs, A and B, and add a Joblet C with the intention of running it between A and B, you need to do the following steps:
* Design subjob A by adding components and links to it in the Designer workspace.
* Add a Start component to mark the beginning of subjob B and link it to subjob A using an OnSubjobOk trigger.
* Design subjob B by adding components and links to it after the Start component in the Designer workspace.
* Add a tJobletTriggerInput component to your Joblet C design and link it to other components in your Joblet using data flows or triggers.
* Add a tJobletTriggerOutput component to your Joblet C design and link it to other components in your Joblet using data flows or triggers.
* Drag your Joblet C from the Repository tree view to the Designer workspace between subjob A and subjob B.
* Link your Joblet C to subjob A using an OnComponentOk trigger from the last component of subjob A to the tJobletTriggerInput component of your Joblet C.
* Link your Joblet C to subjob B using an OnComponentOk trigger from the tJobletTriggerOutput component of your Joblet C to the Start component of subjob B.
The minimum requirements to orchestrate this are adding TRIGGER_INPUT and TRIGGER_OUTPUT components into C and linking A, B, and C using OnSubjobOk triggers. These are generic components that allow you to define triggers for your Joblet without depending on specific components. You do not need to add TRIGGER_INPUT and TRIGGER_OUTPUT components into A or B, as these are regular subjobs that can use any type of components or triggers.

質問 # 26
You are building a complex Job and want to explore different options for optimizing execution times using parallelism.
How can you identify execution times to verify the effectiveness of your changes?
Choose 2 answers

  • A. Comparing time stamp in Trace Debug mode.
  • B. Observing the execution time in the Code view.
  • C. Observing the execution times that annotate the flows in the Designer.
  • D. Heading the time stamps from the execution console in the Run view.

正解：C、D

解説：
To identify execution times to verify the effectiveness of your changes, you can use one of these methods:
* Reading the time stamps from the execution console in the Run view. This method allows you to see the start and end time of each subjob and component in your job, as well as the total execution time of the job. You can also see the number of rows processed by each component and the status of the job (success or failure).
* Observing the execution times that annotate the flows in the Designer. This method allows you to see the execution time of each flow (main, lookup, reject, etc.) between components in your job. You can also see the number of rows processed by each flow and the throughput (rows per second) of each flow.
You cannot use these methods to identify execution times:
* Observing the execution time in the Code view. This method does not show you the execution time of your job or its components, but only the generated code of your job in Java or Perl. The Code view is useful for debugging or customizing your code, but not for measuring performance.
* Comparing time stamps in Trace Debug mode. This method does not show you the execution time of your job or its components, but only the values of each column for each row processed by your job. The Trace Debug mode is useful for tracing data quality or transformation issues, but not for measuring performance.

  • C. Reject data using inner join rejections.
  • D. Load single lookup tables only.
  • E. Perform full outer joins.

正解：A、B、E

解説：
Comprehensive and Detailed Explanation:
The tMap component in Talend allows for various data transformation and mapping operations. The correct operations include:
* A. Map data using filters, constraints, and simple explicit joins.
* tMap allows mapping fields between sources and destinations with filters and constraints.
* B. Perform full outer joins.
* Unlike tJoin, tMap supports full outer joins, allowing all records from both tables to be included.
* C. Transform data from single or multiple sources to single or multiple destinations.
* You can map multiple input sources to multiple output targets with transformations.


質問 # 28
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 the score will automatically update.
  • B. Mark the datasets in the dataset list, and the score updates in the detailed view.
  • C. Use the search bar to filter the customer datasets and manually calculate the score.
  • D. Review the rating of selected datasets in the group tab.

正解：A

解説：
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.


質問 # 29
Which method allows you to execute the compiled Job Talend Studio?

  • A. Right-click the Job in the Repository and select Export items.
  • B. Click the Export button in the Edit Properties window.
  • C. Right-click the Job in the Repository and select Build Job
  • D. Select Save As on the main File menu

正解：C

解説：
To execute the compiled job outside Talend Studio, you need to right-click on the job in the Repository tree view and select Build Job option. This option allows you to export your job as an executable file that can be run independently from Talend Studio on any platform that supports Java. You can access this option by right- clicking on your job in the Repository tree view and selecting Build Job. This will open a dialog box where you can configure the build settings, such as destination folder, archive name, context, etc.
You do not need to click the Export button in the Edit Properties window, right-click on the job in the Repository and select Export items, or select Save As on the main File menu. These options are not used to execute the compiled job outside Talend Studio. The Export button in the Edit Properties window is used to export your job properties as an XML file. The Export items option is used to export your items (such as jobs, metadata, routines, etc.) as an archive file that can be imported into another project or workspace. The Save As option is used to save a copy of your job with a different name or location. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Build Job - 7.3]


質問 # 30
You created a Job to process a customer database. Next, you want to debug the Job using Traces Debug and pause the execution when it encounters any records for customers residing in the state of California.

  • A. Right-click the trace on the output of the input component and select Add Breakpoint.
  • B. Open the Debug Run tab of the Run view and click Traces Debug.
  • C. Right-click the trace on the output of the input component and select Show Breakpoint Setup.
  • D. Add a breakpoint in the Advanced Settings tab of the Run view.

正解：C

解説：
To debug a job using Trace Debug mode and pause the execution when it encounters any records for customers residing in the state of California, you need to right-click on the trace on the output of the input component and select Show Breakpoint Setup option. 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. A trace is a link that shows the data flow between components in your job design workspace.
The Show Breakpoint Setup option allows you to set a breakpoint on a trace based on a condition or an expression. A breakpoint is a point where the execution of your job pauses and waits for your action. You can use breakpoints to inspect your data or debug your logic at specific points of your job execution. You can access this option by right-clicking on a trace on your job design workspace and selecting Show Breakpoint Setup. This will open a dialog box where you can enter a condition or an expression for your breakpoint.
For example, if you want to pause your job execution when it encounters any records for customers residing in the state of California, you can enter this condition for your breakpoint:
row1.state == "CA"
This will make your job stop at the trace where this condition is met and show you the values of each column for that row.
You do not need to add a breakpoint in Advanced settings tab of Run view, open Debug Run tab of Run view and click Trace Debug button, or right-click on trace on output of input component and select Add Breakpoint option. These options are not used to set breakpoints based on conditions or expressions. The Advanced settings tab of Run viewis used to configure advanced settings for your job execution, such as JVM arguments, statistics parameters, implicit context load parameters, etc. The Debug Run tab of Run view is used to access Trace Debug mode, but not to set breakpoints. The Add Breakpoint option is used to add a simple breakpoint on a trace without any condition or expression.

質問 # 31
You need to set up a server in your Talend environment that enables several members of your team to collaborate on a project.
Which application must you enable before working on a remote project?

  • A. Git or SVN client must be installed on each developed workstation.
  • B. Git or SVN server instance must be running.
  • C. Talent Administration Center instance must be running with the team members and project configured.
  • D. Talend admission Center service must be running on each development workstation.

正解：B、C

解説：
To set up a server in your Talend environment that enables several members of your team to collaborate on a project, you need to enable two applications before working ona remote project: Git or SVN server instance and Talend Administration Center instance. These applications are used to manage version control and collaboration for your project.
Git or SVN server instance is a server application that allows you to store and track changes of your project files using a version control system. Git and SVN are two popular version control systems that are supported by Talend Studio. You need to have a Git or SVN server instance running and accessible by your team members before working on a remote project. You also need to have a Git or SVN client installed on each development workstation to connect to the server and perform version control operations.
Talend Administration Center is a web-based application that allows you to manage users, projects, tasks, execution servers, and licenses for your Talend environment. You need to have a Talend Administration Center instance running and accessible by your team members before working on a remote project. You also need to configure the team members and project settings in Talend Administration Center to grant access and permissions for your project.

質問 # 32
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. Java Function paramters
  • B. Context parameters
  • C. CommandLine options
  • D. File

正解：B

解説：
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.

* 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.


質問 # 36
Which statements are true when comparing a Joblet to a tRunJob component?
Choose 3 answers

  • A. The nested Job called by a tRunJob component cannot use the same context variable of the Job in which it is used.
  • B. The performance of tRunJob component is better than running an equivalent Job using a Joblet.
  • C. Building a Joblet typically requires the use of generic input, and trigger component.
  • D. The performance of a Joblet if better than running an equivalent Job using a tRunJob component.
  • E. A Joblet uses the same context variables of the Job in which it is used, unlinke a tRunJob component.

正解：A、C、E

解説：
A Joblet is a reusable piece of a job that can be used in multiple jobs as a single component. A tRunJob component is a component that allows you to call another job as a subjob within a parent job. When comparing a Joblet to a tRunJob component, these statements are true:
* A Joblet uses the same context variables of the job in which it is used, unlike a tRunJob component. A context variable is a variable that can store a value that can be changed at runtime or between different contexts. A Joblet inherits the context variables from the job that contains it and does not have its own context variables. A tRunJob component can pass context variables from the parent job to the child job, or use a specific context for the child job.
* Building a Joblet typically requires the use of generic input and trigger components. A Joblet can have one or more input and output flows that connect it with other components in a job. To create these flows, you need to use generic input and trigger components, such as tJobletInput, tJobletOutput, tJobletTriggerInput, and tJobletTriggerOutput. These components allow you todefine schemas and triggers for your Joblet without depending on specific components.
* The nested job called by a tRunJob component cannot use the same context variables of the job in which it is used. A nested job is a job that is called by another job using a tRunJob component. A nested job can have its own context variables or receive context variables from its parent job, but it cannot use the same context variables as its parent job. This means that if you have two context variables with the same name in both jobs, they will be treated as separate variables and will not share values.
These statements are false when comparing a Joblet to a tRunJob component:
* The performance of tRunJob component is better than running an equivalent job using a Joblet. The performance of a Joblet is better than running an equivalent job using a tRunJob component. This is because a Joblet is integrated into the main code of the job and does not require launching another JVM process or loading another metadata object like a tRunJob component does.

Which API definitions are supported by tRESTRequest?

  • A. CSV definition file
  • B. OAS/Swagger 2.0 file
  • C. WSDL file
  • D. XML definition file

正解：B

解説：
Comprehensive and Detailed Explanation:
ThetRESTRequest componentsupportsOpenAPI Specification (OAS)/Swagger 2.0for initializing component endpoints, API mappings, and documentation.
* OAS/Swagger 2.0 file (Correct Answer - Option D):
* tRESTRequest allows API-first development by importing aSwagger 2.0 (OAS) definition.
* This enables automatic configuration of API endpoints, request parameters, and response structures.
* Why not other options?
* CSV definition file (Option A):Not a valid API definition format.
* XML definition file (Option B):XML files are not standard for REST API definitions.
* WSDL file (Option C):WSDL is used for SOAP-based web services, not REST.
