|
You are an application developer. You use a hypervisor with multiple virtual machines installed to test your applications on various operating system 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 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? |
Create a new virtual switch configured for host-only (internal) networking. Connect the virtual network interfaces in the virtual machines to the virtual switch. |
|
Match the virtualization feature on the right with the appropriate description on the left. |
Flexibility – Moving virtual machines between hypervisor hosts Testing – Verifying that security controls are working as designed Server consolidation – Performing a physical-to-virtual migration (P2V) Sandboxing – 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. |
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. |
