Obtaining and installing a valid SSL certificate from a trusted certificate authority on Tableau Server Obtaining and installing a valid SSL certificate from a trusted certificate authority is a crucial step in implementing SSL encryption in Tableau Server. This certificate is used to establish a secure communication channel between the server and clients, ensuring that data transmitted is encrypted and protected from interception or tampering. Option A is incorrect be-cause while configuring encryption algorithms is part of SSL configuration, obtaining and installing a valid SSL certificate is the primary and most critical step. Option C is incorrect as setting up a dedicated SSL decryption server is not a standard practice for SSL implementation in Tableau Server. Option D is incorrect because enabling SSL on client devices, while important for overall security, is not directly related to the implementation of SSL on Tableau Server.
