Which statement about memory reuse technology is incorrect?

The statement regarding memory reuse technology that is deemed incorrect is the one suggesting that a higher reuse ratio always results in better performance for the virtual machine. While memory reuse technology indeed aims to enhance resource utilization by allowing multiple virtual machines to share memory pages, an excessively high reuse ratio can lead to performance degradation. This occurs because the more memory pages that are shared, the greater the risk of contention and the increased likelihood that a virtual machine could experience cache misses or reduced memory access speed. Therefore, while memory reuse can improve efficiency, it is not guaranteed that a higher reuse ratio will translate to better performance for every scenario. Performance optimization involves balancing the reuse ratio with the needs of individual virtual machines and their memory usage patterns.

The other options present accurate information about the benefits and functionalities of memory reuse technology, focusing on its ability to improve virtual machine deployment, optimize memory usage based on demand, and allow total virtualized memory to exceed physical memory constraints effectively.
