질문 # 45
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. Talent Administration Center instance must be running with the team members and project configured.
C. Talend admission Center service must be running on each development workstation.
D. Git or SVN server instance must be running.

정답：B,D

설명：
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.

질문 # 46
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. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into A.
B. Link A, B and C using On Subject Ok triggers.
C. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into B.
D. Add TRIGGER_INPUT and TRIGGER_OUTPUT components into C

정답：B,D

설명：
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.
