58 Eleventh Hour Security : Exam SY0-201 Study Guide a problem later. What is your best course of action to accomplish the assigned tasks? A. Build new virtual machines on the physical host to match the secu- rity servers. Once loaded, you copy the data files from each of the original server to the virtual servers. You leave the original servers online until the new servers are verified as working. B. You copy the disk drives of the original servers to the SAN. Once com- pleted, you create new virtual machines and attach the data on the SAN to the virtual machine. You shut down the original servers. C. You use a physical to virtual migration tool to copy the disk drives of the physical servers to the new virtual machines. Once completed, you shut down the original server and power on the new virtual server. D. You create a new virtual machine and use a bulk copy utility to copy all the data from the source servers to the new virtual machines. When complete, you leave the original servers online until the new servers are verified. 5. What is a benefit of application virtualization? A. Applications are executed on the local clients instead of the applica- tion server. B. Applications are all Web based. C. Only Windows clients can access the published applications. D. Any device that can run the client can access the applications. ANSWERS 1. The correct answer is B. Virtual machines can be rapidly restored if they are breached. By using the snapshot features or using a template, a new virtual machine can quickly be restored at a known state without the breach that was detected. Answer A is incorrect because virtual machines are just like physical machines and can have security templates applied to them the same as any physical server. Answer C is incorrect because a virtual machine can join an Active Directory and can even be a domain controller. Answer D is incorrect because just like a physical server virus attacks are capable of compromising the server. 2. The correct answer is D. Virtual machines have the same hardware driv- ers when running on the same hypervisor. The hypervisor isolates the virtual machines from differences in the physical hardware. Answers A, B, and C are incorrect because the virtual machines never see the physi- cal network or RAID controllers. The hypervisor and the virtual drivers ensure that all the virtual machines see the same device drivers, regard- less of the physical resources.
