Q62. CORRECT TEXT 

Which virsh subcommand is used to change the CD-ROM image file attached to a virtual machine? (Specify ONLY the subcommand without any parameters.) 

Answer: 

change-media, virsh change-media, qemu-monitor-command, virsh qemu- monitor-command 


Q63. How does high availability clustering relate to periodic storage backup? (Choose TWO correct answers.) 

A. Regular backups become generally unnecessary as any data loss or corruption is automatically recovered by the high availability cluster. 

B. Regular backups remain vital as they allow restoration of data that was accidentally deleted or corrupted. 

C. Regular backups may be reduced to the cluster configuration and cluster state data as this information is sufficient to recover any state of the cluster, including data, at any time. 

D. Backups should be located only on the local storage of the cluster and should not be backed up in order to prevent bandwidth congestion. 

E. Backup procedures may have to be adapted to the cluster to ensure complete and recoverable backups. 

Answer: B, E

C. -drive bus=hd,busid=b,src=file.img 

D. -drive file=file.img,index=1,media=disk,if=ide 

E. -drive type=loop,src=file.img,dst=disk:hdb 

Answer: D 


Q65. Which of the following is true regarding the CPU of a KVM virtual machine? (Choose TWO correct answers.) 

A. Each KVM virtual machine can only have one CPU with one core. 

B. KVM virtual machines support multiple virtual CPUs in order to run SMP systems. 

C. The CPU architecture of a KVM virtual machine is independent of the host system's architecture. 

D. For each KVM virtual machine one dedicated physical CPU core must be reserved. 

E. KVM uses the concept of virtual CPUs to map the virtual machines to physical CPUs. 

Answer: B, E

Q67. Which of the following statements are true regarding resource management for full virtualization? (Choose TWO correct answers.) 

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

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

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

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

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

Answer: C, D 


Q68. Which of the following statements is true regarding VirtualBox? 

A. VirtualBox uses container-based virtualization and can only run virtual machines using the operating system of the host system. 

B. VirtualBox can only be run from a graphical desktop environment and not from the text console. 

C. VirtualBox provides special device drivers for several operating systems to enhance the virtual machine's performance. 

D. VirtualBox contains a hypervisor that runs independently from any other operating system on a bare metal host. 

E. VirtualBox is part of the vanilla Linux kernel and does not require any additional software installation on recent Linux distributions. 

Answer: C

Q70. Which of the following statements describes fencing resources in a high availability cluster? 

A. Fencing is the automated stop and restart of cluster services that suffer from software errors. 

B. Fencing is the disconnection of a failed cluster node from any other cluster resources. 

C. Fencing is the forwarding of incoming network connections to backend servers. 

D. Fencing is the assignment of services to different cluster nodes to avoid interference of the services.
