Lpi LPIC-3 Exam 305: Virtualization and Containerization Sample Questions (Q15-Q20):

NEW QUESTION # 15
What is the purpose of capabilities in the context of container virtualization?

Answer: B

Explanation:
Explanation
Capabilities are a way of implementing fine-grained access control in Linux. They are a set of flags that define the privileges that a process can have. By default, a process inherits the capabilities of its parent, but some capabilities can be dropped or added by the process itself or by the kernel. In the context of container virtualization, capabilities are used to prevent processes from performing actions that might infringe the container, such as accessing the host's devices, mounting filesystems, changing the system time, or killing other processes. Capabilities allow containers to run with a reduced set of privileges, enhancing the security and isolation of the container environment. For example, Docker uses a default set of capabilities that are granted to the processes running inside a container, and allows users to add or drop capabilities as needed12.

NEW QUESTION # 16
Which of the following commands are needed to establish a private network between two (or more) KVM virtual machines that is not visible to other KVM instances on the same KVM host? (Choose THREE correct answers.)

Answer: A,B,C

Explanation:
To establish aprivate, isolated networkbetween KVM virtual machines on the same host, Linux networking tools are used to create and managevirtual network bridges and TAP interfaces. According to KVM and Linux virtualization documentation, the core components required arebrctl,tunctl, andifconfig(or the modern ip command).
Thebrctlutility is used to create and manage Linux bridge interfaces, which act as virtual switches connecting multiple virtual machines.tunctlis used to create TAP interfaces that allow virtual machines to connect to the bridge.ifconfigis used to bring interfaces up and assign network parameters.
ebtablesis not strictly required for creating a private network; it is used for filtering Ethernet frames.ipconfig is a Windows networking command and is not applicable to Linux systems.
Therefore, the correct and documented answers areB, D, and E.


NEW QUESTION # 17
What does IaaS stand for?

Answer: B


NEW QUESTION # 18
Which of the following statements are true regarding hardware-based virtualization? (Choose TWO correct answers.)

Answer: A,D

Explanation:
Hardware-based virtualization usesCPU-assisted virtualization featuresto improve performance and isolation when running virtual machines. According to virtualization documentation, modern processors such asIntel VT-xandAMD-Vprovide special CPU instructions that allow the processor totrap and transfer control to the hypervisorwhen sensitive or privileged instructions are executed by a guest virtual machine.
This behavior makes statementAcorrect.
Additionally, hardware-based virtualizationrequires explicit CPU and chipset support, which is now standard in most modern x86-based systems. These hardware extensions reduce the need for complex software emulation and enable near-native performance for virtual machines. Therefore, statementCis also correct.
StatementBdescribes full software emulation rather than hardware-assisted virtualization and is incorrect in this context. StatementDis false because hardware-based virtualization is widely available and heavily used on x86 architectures in enterprise, cloud, and desktop environments.
Virtualization notes consistently highlight that hardware-based virtualization is the foundation for platforms such asKVM, Xen, VMware ESXi, and Hyper-V, making it a critical technology in modern computing.
Thus, the correct answers areA and C.


NEW QUESTION # 19
What is the purpose ofcloud-init?

Answer: C

Explanation:
Cloud-init is a tool that processes configurations and runs through five stages during the initial boot of Linux VMs in a cloud. It allows users to customize a Linux VM as it boots for the first time, by applying user data to the instance. User data can include scripts, commands, packages, files, users, groups, SSH keys, and more.
Cloud-init can also interact with various cloud platforms and services, such as Azure, AWS, OpenStack, and others. The purpose of cloud-init is to prepare the generic image of an laaS instance to fit a specific instance's configuration, such as hostname, network, security, and application settings. References:

* Understanding cloud-init - Azure Virtual Machines
* Tutorial - Customize a Linux VM with cloud-init in Azure - Azure Virtual Machines
