An administrator is managing a virtualized environment with a mix of VMs. Some VMs are critical and require high availability, while others are less critical and can tolerate downtime. The administrator wants to ensure that critical VMs are automatically restarted on another host if the current host fails. Which feature should the administrator configure?

High availability (HA) with automatic VM restart

Which security challenge is specific to virtualized environments compared to traditional physical servers?

Virtual machines cannot be isolated from each other

Physical servers are more susceptible to malware than virtual machines

The hypervisor becomes a new attack surface that, if compromised, could affect all VMs on the host

Virtualization eliminates the need for firewalls

A company is experiencing performance degradation on a virtualized host. The administrator suspects that one VM is consuming excessive I/O, affecting other VMs. Which action would best mitigate this issue?

Disable memory ballooning on the VM

Configure I/O throttling or storage I/O control on the VM

Migrate the VM to a different host

Increase the number of vCPUs on the VM

What is a virtual machine (VM) in a virtualized environment?

A storage device that is shared among multiple servers

A type of hypervisor that manages multiple physical servers

A physical server that is dedicated to a single application

A software-based emulation of a physical computer that runs an operating system and applications

In a virtualized environment, what is the purpose of setting CPU and memory limits on a virtual machine?

To guarantee that the VM always has the highest priority for resources

To prevent the VM from using more resources than allocated, ensuring fair sharing among VMs

To allow the VM to automatically scale to unlimited resources

To increase the physical hardware capacity of the host server
