What memory health metrics can be retrieved from a host?

• A. CPU load and Memory usage
• B. Memory used and Page faults
• C. Disk space and Network connections
• D. CPU temperature and Usage time

Answer: (B)

Memory health metrics focus specifically on evaluating the performance and availability of memory resources within a host system. When considering what can be retrieved from a host regarding memory, metrics such as memory used and page faults are crucial. Memory used indicates the amount of memory currently being utilized by processes and services running on the host. This is a key metric because it helps administrators understand how much memory is available for additional applications or services and whether the system is potentially overcommitted with its memory resources. Page faults, on the other hand, occur when a program requests a page of memory that is not currently loaded in RAM. Monitoring page faults is important because a high number of page faults can indicate that the system is struggling to access memory quickly, which can significantly impact performance. It serves as an indication of whether the system needs more physical memory or if the memory management policy needs to be revisited. In contrast, the other answer choices reflect various system metrics that are not particularly relevant to memory health. CPU load and memory usage do touch on memory metrics, but they combine CPU information, which distracts from a pure memory health focus. Disk space and network connections relate to storage and network performance, respectively, and do not provide insights into memory health. Similarly, CPU temperature and
