A company's ERP application is running slowly on a virtualized server. The hypervisor administrator reports that the VM's CPU ready time is high. The application is not CPU-intensive, but it is I/O-intensive. Which action would best improve application performance?

Move the VM's virtual disk to a faster storage tier

Increase the number of virtual CPUs assigned to the VM

Move the VM to a host with more physical CPU cores

Enable memory ballooning on the VM

An administrator notices that a Windows server has not received any security updates for the past three months, even though the Windows Update service is running. The server is in a DMZ and uses a WSUS server for updates. Which step should be taken first to diagnose the issue?

Review the WSUS console to see if the server is listed as needing updates

A user-space application has caused a segmentation fault that crashed the entire system.

The root filesystem could not be mounted, often because the kernel lacks the required driver or the root device is not available.

The system has run out of memory and the kernel has killed the init process.
