It is important to set up CSB Role Based Permission from CSB > Users > Roles because:
Until CSB Role Based Permission is enabled, all users with access to CSB have all permissions in the tool. This means that any user who can log in to CSB can perform any action, such as creating, editing, deleting, publishing, or syncing pages, components, settings, or translations. This could pose a risk of unauthorized or accidental changes, errors, or conflicts in the site configuration and content. Therefore, it is recommended to enable CSB Role Based Permission and assign different roles to different users based on their responsibilities and tasks.
Site setup settings are located within CSB and should only be accessed by trained administrators. These settings include the site name, site ID, site URL, site language, site theme, site layout, site logo, site favicon, site integrations, site analytics, and site SEO. These settings are critical for the functionality, performance, and appearance of the site, and should not be modified by untrained or inexperienced users. Therefore, it is recommended to set up CSB Role Based Permission and restrict the access to these settings to only the administrators who are responsible for the site setup and maintenance.
The other two options are incorrect because:
Until CSB Role Based Permission is enabled, NO users can access CSB. This is not true, as users can still access CSB if they have the permission to access the Career Site Builder tool in the Provisioning system. However, they will have all permissions in the tool, which is not desirable for the reasons explained above.
Only one CSB role can be assigned per user, so additional roles may need to be created to satisfy your customer's permission requirements. This is not true, as users can have multiple CSB roles assigned to them, as long as the roles do not conflict with each other. For example, a user can have both the Content Editor and the Translator role, which allows them to edit and translate the site content. However, a user cannot have both the Administrator and the Content Editor role, as the Administrator role already includes the Content Editor role.

Option A is correct because the recruiter must include the job with Sync Recruiting Jobs to enable Real Time Job Sync for that job. Sync Recruiting Jobs is a field in the job requisition that indicates whether the job should be synced to the Career Site Builder site or not. If the recruiter does not check this field, the job will not be synced and will not display on the site1.
Option B is incorrect because the recruiter does not need to have permissions for Career Site Builder to sync the jobs to the site. Career Site Builder is a tool for administrators to design and configure the career site, not for recruiters to post jobs. The recruiter only needs to have permissions for Recruiting Management to create and manage job requisitions2.
Option C is correct because the recruiter must include a country for the job to be synced to the Career Site Builder site. The country is a mandatory field in the job requisition that determines the locale and language of the job posting. If the recruiter does not enter a country, the job will not be synced and will not display on the site1.
Option D is incorrect because the recruiter does not need to include a job description for the job to be synced to the Career Site Builder site. The job description is an optional field in the job requisition that provides more details about the job role and responsibilities. If the recruiter does not enter a job description, the job will still be synced and displayed on the site, but it will have less information for the candidates1.

According to the SAP SuccessFactors Recruiting: Candidate Experience Administration course1, before the CSB kickoff call, the following actions are recommended:
Assist the customer to complete the Readiness Checklist. This checklist helps the customer to prepare for the CSB implementation by gathering the necessary information and assets, such as logos, images, videos, etc.
Review the statement of work (SOW). This document defines the scope, deliverables, timeline, and responsibilities of the CSB project. It is important to review the SOW to ensure that the customer's expectations and requirements are aligned with the project plan and budget.
Developing the CSB project plan and finishing the CSB Configuration Workbook are not recommended actions before the CSB kickoff call. These tasks are usually done after the kickoff call, as part of the CSB implementation process.

Conduct the job delivery intake meeting. This is the first step in the job delivery process, where you gather the customer's requirements and expectations for job distribution, such as the target job boards, the budget, the frequency, and the tracking methods1.
Create the customer's standard XML feeds. This is the second step in the job delivery process, where you configure the XML feeds that will deliver the jobs from the customer's SAP SuccessFactors Recruiting system to the selected job boards2. You can use the Job Delivery Toolkit to create and test the XML feeds3.
Train your customers how to populate their preferred sources in the Career Site Builder Site Source Editor. This is the final step in the job delivery process, where you teach the customers how to manage their preferred sources, such as job boards, social media, and employee referrals, in the Career Site Builder Site Source Editor4. This allows the customers to control which sources are displayed on their career site and how they are tracked.
