A company's data center is running out of physical space and power. The IT manager wants to increase server utilization without purchasing new hardware. Which approach directly addresses this goal?

Implementing server virtualization

A data center manager must ensure that a critical application remains available during a planned maintenance window for the main power feed. The application runs on virtual machines. Which combination of data center components is most appropriate to maintain availability?

Uninterruptible power supply (UPS) and a backup generator

Redundant network switches and a firewall

A load balancer and a secondary data center

RAID 5 storage and a backup tape drive

A company's virtualized environment is experiencing performance issues. The hypervisor logs show high CPU ready time on several VMs. The physical host has 16 cores. Which action is most likely to resolve the issue?

Add more RAM to the physical host
