Allows for the partitioning of server hardware with the use of a hypervisor by enabling each virtual machine (VM) to use a slice of the central processing unit (CPU) time & sharing random access memory (RAM).
(a)
True or False. Before virtualization when a new application was required server hardware had to be purchased and exclusively used for that application even if the application didn't use the full resources of the server it was downloaded on.
True
False
Is similar to a physical switch but is a built-in component in your hypervisor & doesn't have the same limitations on the number of ports.
(a)
Which statements are true about virtual switches?
Virtual switches only care about the MAC addresses of the VMs logically attached.
If a MAC address is unknown Virtual switches flood the frame to all active ports..
If the MAC address is unknown the virtual switch will forward it to a physical switch via the uplink port and allow the physical switch to forward the frame.
All the above
Is similar to a physical firewall but can be a firewall appliance installed as a virtual machine or a kernel mode process in the hypervisor.
(a)
Important difference between a virtual firewall appliance & virtual firewall kernel modules.
In virtual firewall kernel modules the traffic never leaves the host
In a virtual firewall the traffic never leaves the host
Virtual firewalls can be backed up like any other virtual machine
None of the above
Is a piece of software that pretends to be physical hardware; communicates directly between the VM and the virtual switch.
(a)
Sits between the hardware or operating system & the virtual machine (VM) to allow for resource sharing, time sharing of VMs to the physical hardware & virtualization of the guest operating systems (VMs).
(a)
The hardware the hypervisor is installed on is called the:
(a)
The virtual machines that a hypervisor sits between is called:
(a)
Name 1 of 3 types of hypervisors.
(a)
Name the 3 types of hypervisors.
Type 1 hypervisor
Type 2 hypervisor
Type 3 hypervisor
Hybrid hypervisor
Software hypervisor
Is a software that runs directly on the hardware; its only purpose is to share the hardware among the VMs running as the guest operating system,
(a)
Is a software that runs directly on the host operating system. It runs as a process in the host operating system & talks directly to the CPU via Intel VT or AMD-V.
(a)
