B. Assign an laaSinstance to a specific computingnode within a cloud.
C. Prepare the generic image of an laaS instance to fit a specific instance's configuration.
D. Standardize the configuration of infrastructure services, such as load balancers or virtual firewalls in a cloud.

正解：C

質問 # 28
Which statement is true regarding the Linux kernel module that must be loaded in order to use QEMU with hardware virtualization extensions?

A. It must be loaded into the Kernel of the host system in order to use the visualization extensions of the host system's CPU
B. It must be loaded into the kernel of the first virtual machine as it interacts with the QEMU bare metal hypervisor and is required to trigger the start of additional virtual machines
C. It must be loaded into the kernel of each virtual machine to provide Para virtualization which is required by QEMU.
D. It must be loaded into the kernel of the host system only if the console of a virtual machine will be connected to a physical console of the host system
E. It must be loaded into the kernel of each virtual machine that will access files and directories from the host system's file system.

正解：A

質問 # 29

A. XML files
B. SQLite databases
C. INI-style text files
D. Text files containing key/value pairs
E. Java-like properties files

正解：A

質問 # 30
The commandvirsh vol-list vmsreturns the following error:
error: failed to get pool 'vms'
error: Storage pool not found: no storage pool with matching name 'vms ' Given that the directory/vmsexists, which of the following commands resolves this issue?

A. dd if=/dev/zero of=/vms bs=1 count=0 flags=name:vms
B. virsh pool-create-as vms dir --target /vms
C. libvirt-poolctl new --name=/vms --type=dir --path=/vms
D. touch /vms/.libvirtpool
E. qemu-img pool vms:/vms

正解：B

解説：
The command virsh pool-create-as vms dir --target /vms creates and starts a transient storage pool named vms of type dir with the target directory /vms12. This command resolves the issue of the storage pool not found error, as it makes the existing directory /vms visible to libvirt as a storage pool. The other commands are invalid because:
* dd if=/dev/zero of=/vms bs=1 count=0 flags=name:vms is not a valid command syntax. The dd command does not take a flags argument, and the output file /vms should be a regular file, not a directory3.
* libvirt-poolctl new --name=/vms --type=dir --path=/vms is not a valid command name. There is no such command as libvirt-poolctl in the libvirt package4.
* qemu-img pool vms:/vms is not a valid command syntax. The qemu-img command does not have a pool subcommand, and the vms:/vms argument is not a valid image specification5.
* touch /vms/.libvirtpool is not a valid command to create a storage pool. The touch command only creates an empty file, and the .libvirtpool file is not recognized by libvirt as a storage pool configuration file6.

質問 # 31
Which of the following statements are true regarding IaaS computing instances? (Choose TWO correct answers.)

A. Each user of an IaaS cloud has exactly one computing instance
B. The root file system of a computing instance is always persistent and can be accessed after the instance is destroyed
C. Instances may be created when needed and destroyed when they become obsolete
D. Once created, computing instances are seldom deleted to ensure data accessibility
E. Creation of new instances can be automated by using scripts or APIs and service interfaces

正解：C、E

解説：
Infrastructure as a Service (IaaS) provides on-demand virtual computing resources that can be dynamically created and destroyed. According to cloud computing documentation, IaaS instances are designed to be ephemeral, allowing users to launch instances when needed and terminate them when no longer required. This makes statement A correct.
Additionally, IaaS platforms expose APIs and service interfaces that enable full automation of instance lifecycle management. Instances can be created, modified, and deleted programmatically using scripts, orchestration tools, or cloud SDKs, making statement B correct.
Statement C is incorrect because root disks are often ephemeral unless explicitly configured as persistent volumes. Statement D contradicts the elastic nature of IaaS, and statement E is false because users may have zero, one, or many instances.
Therefore, the correct answers are A and B.
