What is a trunk port, and why is it necessary when using VLANs?

What component serves as the core of the vSphere ESXi hypervisor?

What virtualization product supports the use of 4-KB disk sectors within virtual drives, allowing the virtual machine to take advantage of increased storage capacity?

What type of malware is a virus that operates at the same privilege as the hypervisor and utilizes various methods to hide from detection?

What are the two different types of Storage Area Network system?

What DRS mode has the ability to move VMs to other ESXi hosts based on a preset performance threshold rating, requiring no actions on behalf of an ESXi administrator?

What role does the iSCSI initiator play in establishing a connection to an iSCSI target?

When using Microsoft Hyper-V, what type of virtual switch should you utilize if you want to limit communication of a virtual machine to only virtual machines running on the host?

What advanced virtual hard disk format, introduced by Windows Server 2012 R2, provides increased storage capacity of up to 64 TB per VM disk, improved performance, and security?
