最新的 LPIC-3 305-300 免費考試真題 (Q85-Q90):

問題 #85
Which of the following statements are true for full virtualization? (Choose TWO correct answers)

答案：A,B

解題說明：
Full virtualization is a virtualization approach where the hypervisor provides a complete simulation of the underlying hardware, allowingunmodified guest operating systemsto run without awareness of virtualization. Virtualization documentation consistently states that one of the defining characteristics of full virtualization is thatguest operating systems do not need to be modified, making optionCcorrect.
Additionally, modern full virtualization platforms benefit fromhardware-assisted virtualization, such as Intel VT-x and AMD-V CPU extensions. These extensions significantly improve performance by offloading virtualization tasks to the processor, making optionBcorrect.
Option A is incorrect because Linux-based hypervisors like KVM can perform full virtualization entirely within the Linux ecosystem. Option D is false because all virtualization introduces some performance overhead, even if minimal. Option E is incorrect because full virtualization is widely used in production environments, including enterprise data centers and cloud platforms.
Therefore, based on virtualization principles and documentation, the correct answers areB and C.


問題 #86
FILL BLANK
What command is used to run a process in a new Linux namespace? (Specify ONLY the command without any path or parameters.)

答案：

解題說明：
unshare
Explanation
The unshare command is used to run a process in a new Linux namespace12. It takes one or more flags to specify which namespaces to create or unshare from the parent process1. For example, to run a shell in a new mount, network, and PID namespace, one can use:
unshare -mnp /bin/bash
References:
* 1: unshare(1) - Linux manual page - man7.org
* 2: A gentle introduction to namespaces in Linux - Packagecloud


問題 #87
Which command was used in Xen 3.x as a predecessor of the xl command?

答案：

解題說明：
xm
Explanation:
In Xen 3.x, the primary command-line tool used to manage virtual machines wasxm. According to Xen virtualization documentation, xm was part of the original Xen management stack and provided commands to create, start, stop, migrate, and monitor Xen domains.
As Xen evolved, the xm toolstack was deprecated and replaced by thexltoolstack. The xl command interfaces directly with the Xen hypervisor and offers better performance, improved maintainability, and reduced complexity. Modern Xen installations no longer support xm, but it remains historically significant as the predecessor to xl.
Therefore, the correct answer isxm.


問題 #88
Which statement is true regarding the Linux kernel module that must be loaded in order to use QEMU with hardware virtualization extensions?

答案：B

解題說明：
Explanation
The Linux kernel module that must be loaded in order to use QEMU with hardware virtualization extensions is KVM (Kernel-based Virtual Machine). KVM is a full virtualization solution that allows a user space program (such as QEMU) to utilize the hardware virtualization features of various processors (such as Intel VT or AMD-V). KVM consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. KVM must be loaded into the kernel of the host system in order to use the virtualization extensions of the host system's CPU. This enables QEMU to run multiple virtual machines with unmodified Linux or Windows images, each with private virtualized hardware. KVM is integrated with QEMU, so there is no need to load it into the kernel of each virtual machine or the first virtual machine. KVM also does not require paravirtualization, which is a technique that modifies the guest operating system to communicate directly with the hypervisor, bypassing the emulation layer. References:
* Features/KVM - QEMU
* Kernel-based Virtual Machine
* KVM virtualization on Red Hat Enterprise Linux 8 (2023)


問題 #89
Which directory is used bycloud-initto store status information and configuration information retrieved from external sources?

答案：A

解題說明：
Explanation
cloud-init uses the /var/lib/cloud/ directory to store status information and configuration information retrieved from external sources, such as the cloud platform'smetadata service or user data files. The directory contains subdirectories for different types of data, such as instance, data, handlers, scripts, and sem. The instance subdirectory contains information specific to the current instance, such as the instance ID, the user data, and the cloud-init configuration. The data subdirectory contains information about the data sources that cloud-init detected and used. The handlers subdirectory contains information about the handlers that cloud-init executed.
The scripts subdirectory contains scripts that cloud-init runs at different stages of the boot process, such as per-instance, per-boot, per-once, and vendor. The sem subdirectory contains semaphore files that cloud-init uses to track the execution status of different modules and stages. References:
* Configuring and managing cloud-init for RHEL 8 - Red Hat Customer Portal
* vsphere - what is the linux file location where the cloud-init user ...
