Final answer:
When adding more swap space, both repartitioning the existing disk (option I) or adding swap space on a different drive or as a file (option II) are viable options. The correct choice is both I and II, providing flexibility in managing a system's swap space.
Step-by-step explanation:
When adding more swap space to a system where a fixed amount of swap space has already been created, it is possible to do so by either repartitioning of the disk or by adding another swap space elsewhere. The correct answer to the question is c) both I and II. Option I involves resizing existing partitions to create a new swap partition, which can be a complex process and may require third-party tools or a live CD/USB. Option II involves creating a swap file or a swap partition on a different disk without modifying existing partitions, which is generally simpler and less risky.
To add swap space through the first method, you would typically use a partition manager to resize existing partitions and create new swap space. Through the second method, swap space can be added by creating a swap file on an existing file system or adding a swap partition on a new drive. These methods provide flexibility for administrators to ensure that a system has sufficient swap space without major disruptions or data low.
