   A system administrator needs to apply a critical security patch to a VM. The VM runs a production database and cannot be rebooted during business hours. The administrator wants to minimize downtime and be able to roll back if the patch causes issues. What should the administrator do?

   • ALive migrate the VM to another host, apply the patch, and then migrate back.
   • BApply the patch without a snapshot and rely on the patch uninstaller.
   • CTake a snapshot of the VM before applying the patch, then apply the patch and reboot the VM.
   • DClone the VM, apply the patch to the clone, and then switch traffic to the clone.

   A company is designing a remote-office virtualization solution. The office has a single physical server with limited RAM and CPU. They need to run a few lightweight VMs for file sharing and print services. The IT staff is not highly experienced with virtualization. They want to minimize management overhead and avoid the need for a separate management console. Which solution is most appropriate?

   • ADeploy a distributed virtual switch to manage networking.
   • BInstall a type 1 hypervisor and manage it via command-line interface.
   • CInstall a type 2 hypervisor on the server's host OS and use its graphical management interface.
   • DUse a container runtime on the host OS instead of VMs.

   Which statement accurately describes a type 1 hypervisor?

   • AIt is a software layer that runs only within a guest operating system to provide nested virtualization.
   • BIt runs as an application on top of a host operating system and relies on that OS for hardware access.
   • CIt requires a dedicated management partition running a full operating system for all virtualization functions.
   • DIt runs directly on the physical hardware and provides virtualization services to guest operating systems.

   A network administrator is configuring a virtual switch for a multi-tenant environment. Each tenant has its own VLAN, and the administrator needs to ensure that traffic from different tenants is isolated. The physical switch ports connecting to the host are configured as trunks. What should the administrator configure on the virtual switch?

   • AUse a separate virtual switch for each tenant.
   • BEnable promiscuous mode on all port groups.
   • CDisable VLAN tagging and rely on the physical switch to tag traffic.
   • DEnable VLAN tagging on the virtual switch and assign each port group a specific VLAN ID.
