What setting is needed to properly configure a TSM?

A static IP address is essential for properly configuring a TSM (Tivoli Storage Manager) because it provides a consistent network address that does not change over time. This stability is vital for maintaining reliable connections between the TSM server and its clients or other servers, ensuring that backup and restore operations can occur without interruption or the need for reconfiguration. In contrast, a dynamic IP address, which changes periodically, can lead to connectivity issues, making it difficult for the TSM to consistently locate and interact with the devices it manages. The other options, while useful in various contexts, do not provide the necessary stable communication environment required for effective TSM operations. VPN access points and cloud storage integration can enhance security and storage capabilities but do not directly address the need for a fixed and reliable network address that a static IP provides.
