9.4 Virtual Networking

You have configured a virtual network that includes the following virtual components:

Four virtual machines (Virtual OS1, virtual OS2, 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.

Given the port configuration for the virtual switch and the physical switch in the table below, click on all of the virtual and physical machines that virtual OSI can communicate with.

Virtual OS 2 Virtual OS 3

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 OS1, virtual OS2, etc)
One virtual switch

The virtual switch is connected to a physical network allow the virtual machines to communicate with the physical machines out on the physical network.

Given the port configuration for the virtual switch and the physical switch in the table below, click on all of the virtual and physical machines that Virtual OS1 can communicate with

Virtual OS 3 Physical OS 1 Physical OS 2 Physical OS 3 Physical OS 4

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 adversely impact other network hosts if 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?

Connect the virtual network interfaces in the virtual machines to the virtual switch Create a new virtual switch configured for host-only (internal) networking

Flexibility

Testing

Server consolidation

Sandboxing

Moving virtual machines between hypervisor hosts Verifying that security controls are working as designed Performing a physical-to-virtual migration (P2V) Isolating a virtual machine from the physical network

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 in-house application 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, none of your testing virtual machines 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)

Create a new virtual switch configured for bridged (external) networking Connect the virtual network interfaces in the virtual machine to the virtual switch

What key advantage does a virtual router have over a physical router?

Multiple networks can be connected to a single interface

You want to be able to monitor and filter VM-to-VM traffic within a virtual network.

What should you do?

Implement a virtual firewall within the hypervisor

Which of the following statements about virtual NICs are true? (select two)

Multiple virtual NICs can be added to a virtual machine Virtual NICs need the appropriate driver installed to function
