What is isolating a virtual machine from the physical network to allow testing to be performed without
1
impacting the production environment called? -✔✔Sandboxing
Which of the following are disadvantages of server virtualization? -✔✔A compromised host system
might affect multiple servers
Which type of hypervisor runs as an application on the host machine -✔✔Type 2
Which of the following are advantages of virtualization? (Select two.) -✔✔Centralize administration

Which load balancing method distributes a workload across multiple computers? -✔✔Workload
balancing
Which of the following provides the network virtualization solution called XenServer? -✔✔Citrix
Which of the following is a network virtualization solution provided by Microsoft? -✔✔Hyper-V
What is the limit of virtual machines that can be connected to a virtual network? -✔✔Unlimited
, 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 virtual machines used for testing 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 issues, you decide to isolate the virtual machines from the production network. However,
%
they still need to be able to communicate directly with each other.

Control layer through the northbound interface.
Which SDN layer would a load balancer that stops and starts VMs as resource use increases reside
on? -✔✔Application
Software defined networking (SDN) uses a controller to manage devices. The controller is able to
inventory hardware components on the network, gather network statistics, make routing decisions
based on gathered data, and facilitate communication between devices from different vendors. It can
also be used to make widespread configuration changes on just one device.
Which of the following best describes an SDN controller? -✔✔The SDN controller is software
