9.4 Virtualization

You have configured a virtual network that includes the following virtual components:
*Four virtual machines (Virtual OS 1, Virtual OS 2, etc.)
*One virtual switch
The virtual switch is connected to a physical network to allow the virtual machines to communicate with the physical machines out on the physical network.
Give the port configuration for the virtual switch and the physical switch in the table below, click on on all of the virtual and physical machines Virtual OS 1 can communicate with.
Virtual OS 2
Virtual OS 3
Which of the following are disadvantages to server virtualization?

Which of the following are disadvantages to server virtualization?
A failure in one hardware component could affect multiple servers
You have a development machine that contains sensitive information relative to your business.

Centralized administration

You are an application developer. You use a hypervisor with multiple virtual machines installed
to test your applications on various operating systems versions and editions.
Currently, all of your testing virtual machines are connected to the production network through
the hypervisor’s network interface. However, you are concerned that the latest application you
are working on could possible adversely impact other network hosts if mistakes or errors exist in
the code.
To prevent this, you decide to isolate the virtual machines from the production network.
However, they still need to be able to communicate directly with each other.
What should you do? (Select two. Both responses are part of the complete solution.)
Create a new virtual switch configured for host-only (internal) networking.

Connect the virtual network interfaces in the virtual machines to the virtual switch.

You are responsible for maintaining Windows workstation operating systems in your
organization. Recently, an update from Microsoft was automatically installed on your
workstations that caused an application that was developed inhouse
to stop working.
To keep this from happening again, you decide to test all updates on a virtual machine before
allowing them to be installed on production workstations.
Currently, all of your testing virtual machines do not have a network connection. However, they
need to be able to connect to the update servers at Microsoft to download and install updates.
What should you do? (Select two. Both responses are part of the complete solution.)
Connect the virtual network interfaces in the virtual machines to the virtual switch.

Create a new virtual switch configured for bridged (external) networking.

You need to provide DHCP and file share services to a physical network. These services should be deployed using virtualization. Which type of virtualization should you implement?
Virtual servers
You have configured a virtual network that includes the following virtual components:
*Four virtual machines (Virtual OS 1, Virtual OS 2, etc.)
*One virtual switch
The virtual switch is connected to a physical network to allow the virtual machines to communicate with the physical machines out on the physical network.
Give the port configuration for the virtual switch and the physical switch in the table below, click on on all of the virtual and physical machines Virtual OS 1 can communicate with.
Virtual Switch –
