NO.16 Which of the following statements describes the concept behind paravirtualization?

 Guest operating systems are modified to actively cooperate with the hypervisor in order to ease virtualization costs and gain better performance.

 Instead of running full virtual machines, containers are used to separate distinct parts of one commonly shared operating system that appear as a virtual machine.

 To avoid the need for virtualization, special security measures are taken to allow different applications to coexist on one physical machine.

 Each operating system is trusted to use only those resources assigned to it, thereby eliminating the need of an additional virtualization layer.

Section: Virtualization

 By using a network file system or file transfer protocol.

 Guest operating systems are modified to actively cooperate with the hypervisor in order to ease virtualization costs and gain better performance.

 Instead of running full virtual machines, containers are used to separate distinct parts of one commonly shared operating system that appear as a virtual machine.

 To avoid the need for virtualization, special security measures are taken to allow different applications to coexist on one physical machine.

 Each operating system is trusted to use only those resources assigned to it, thereby eliminating the need of an additional virtualization layer.

NO.27 Which of the following statements are true regarding resource management for full virtualization? (Choose TWO correct answers.)

 The hypervisor may provide fine-grained limits to internal elements of the guest operating system such as the number of processes.

 Full virtualization cannot pose any limits to virtual machines and always assigns the host system’s resources in a first-come-first-serve manner.

 It is up to the virtual machine to use its assigned hardware resources and create, for example, an arbitrary amount of network sockets.

 The hypervisor provides each virtual machine with hardware of a defined capacity that limits the resources of the virtual machine.

 All processes created within the virtual machines are transparently and equally scheduled in the host system for CPU and I/O usage.

Section: Virtualization

NO.28 Which of the following commands lists the snapshots existing in the disk image vm1.img?

 qemu-monitor -snapshots -hda vm1.img

Section: Virtualization

NO.29 Which actions should be taken in a load balanced cluster in order to protect the load balancer against outages?

 Load balancers cannot be protected against outages which is why they should always be built on dedicated hardware.

 No actions are necessary as a load balancer cannot become a single point of failure.

 Two or more load balancers should be deployed as a cascade that passes packets from one to the other.

 Two load balancers should be deployed as a failover cluster.

 Load balancers are used for performance and scalability reasons only and cannot be used to archive high availability clusters.
