Which of the following methods can be used to add a system to SAP HANA Studio?

Adding a system to SAP HANA Studio can indeed be accomplished by importing a landscape, which involves configuring multiple systems or instances in one go. When you choose to import a landscape, you typically utilize an existing configuration file that contains information about the HANA systems. This method is efficient for environments where there are multiple HANA instances, allowing for quicker setup and consistency across the landscape.

Importing a landscape means that instead of manually entering the details for each system one by one, the process leverages predefined settings that assist in auto-populating the necessary configurations. This is not only time-saving but also minimizes the risk of human error that can occur during manual entry.

In contrast, adding a system manually requires you to input details such as hostname, instance number, and other parameters individually, making it more labor-intensive and prone to mistakes. The options indicating automatic addition or resource console addendum generally refer to different processes not specifically tied to the efficient means of adding systems typically employed in landscape management. Thus, using the landscape import method is the most effective and streamlined approach for adding systems in SAP HANA Studio.
