Assigning the 'Run As' service account permissions to specific Tableau Server folders and registry settings only When configuring the 'Run As' service account for Tableau Server on a Windows system, it is crucial to assign the account permissions only to those specific folders and registry settings necessary for Tableau Server operation. This ensures that the account has the necessary access to function properly while maintaining a secure environment by limiting its scope of control. Option A is incorrect because setting the 'Run As' account's password to match the administrator's compromises security by potentially exposing administrative credentials. Option B is incorrect as setting the account to expire every 30 days could lead to unnecessary disruptions in service and does not inherently enhance security. Option D is incorrect because enabling remote desktop access for the 'Run As' service account is not a standard practice and could introduce addition-al security risks.
