NEW QUESTION # 36
Which of the following components are essential in Docker architecture? (Select all that apply)
Answer: A,B,C
Explanation:
Docker architecture consists of several core components that enable container creation and management.
According to Docker documentation, theDocker Client,Docker Daemon, andDocker Registryare essential components.
TheDocker Clientis the user-facing command-line interface that sends commands to the daemon. TheDocker Daemon (dockerd)performs the heavy lifting, such as building images, running containers, and managing networks and storage. TheDocker Registrystores container images, enabling image distribution and reuse.
Docker Composeis an optional orchestration tool used to define and run multi-container applications, but it is not an essential architectural component.
Therefore, the correct answers areA, C, and D.
NEW QUESTION # 37
What is oVirt?
Answer: B
Explanation:
oVirt is anopen-source virtualization management platformthat provides a comprehensive infrastructure for managingLinux-based virtualization environments. According to official oVirt and Red Hat documentation, oVirt acts as amanagement layer on top of KVM, offering centralized control over hosts, virtual machines, storage, and networking.
oVirt itself isnot a hypervisor; instead, it relies onKVMas the underlying virtualization technology. It provides both aweb-based management interfaceand REST APIs, enabling administrators to manage large- scale virtualization deployments efficiently. Features include VM lifecycle management, live migration, high availability, storage domain management, and integration with directory services.
Option E describeslibvirt, not oVirt. Options A, C, and D do not match oVirt's documented purpose.
Therefore, the correct answer isB.
NEW QUESTION # 38
Which of the following statements are true regarding resource management for full virtualization? (Choose two.)
Answer: B,E
Explanation:
Resource management for full virtualization is the process of allocating and controlling the physical resources of the host system to the virtual machines running on it. The hypervisor is the software layer that performs this task, by providing each virtual machine with a virtual hardware of a defined capacity that limits the resources of the virtual machine. For example, the hypervisor can specify how many virtual CPUs, how much memory, and how much disk space each virtual machine can use. The hypervisor can also enforce resource isolation and prioritization among the virtual machines, to ensure that they do not interfere with each other or consume more resources than they are allowed to. The hypervisor cannot provide fine-grained limits to internal elements of the guest operating system, such as the number of processes, because the hypervisor does not have access to the internal state of the guest operating system. The guest operating system is responsible for managing its own resources within the virtual hardware provided by the hypervisor. For example, the guest operating system can create an arbitrary amount of network sockets, as long as it does not exceed the network bandwidth allocated by the hypervisor. Full virtualization can pose limits to virtual machines, and does not always assign the host system's resources in a first-come-first-serve manner. The hypervisor can use various resource management techniques, such as reservation, limit, share, weight, and quota, to allocate and control the resources of the virtual machines. The hypervisor can also use resource scheduling algorithms, such as round-robin, fair-share, or priority-based, to distribute the resources among the virtual machines according to their needs and preferences. All processes created within the virtual machines are not transparently and equally scheduled in the host system for CPU and I/O usage. The hypervisor can use different scheduling policies, such as proportional-share, co-scheduling, or gang scheduling, to schedule the virtual CPUs of the virtual machines on the physical CPUs of the host system. The hypervisor can also use different I/O scheduling algorithms, such as deadline, anticipatory, or completely fair queuing, to schedule the I/O requests of the virtual machines on the physical I/O devices of the host system. The hypervisor can also use different resource accounting and monitoring mechanisms, such as cgroups, perf, or sar, to measure and report the resource consumption and performance of the virtual machines.

Answer: C
NEW QUESTION # 40
Which of the following mechanisms are used by LXC and Docker to create containers? (Choose three.)
Answer: A,C,D
Explanation:
Explanation
LXC and Docker are both container technologies that use Linux kernel features to create isolated environments for running applications. The main mechanisms that they use are:
* Linux Capabilities: These are a set of privileges that can be assigned to processes to limit their access to certain system resources or operations. For example, a process with the CAP_NET_ADMIN capability can perform network administration tasks, such as creating or deleting network interfaces. Linux
* capabilities allow containers to run with reduced privileges, enhancing their security and isolation.
* Kernel Namespaces: These are a way of creating separate views of the system resources for different processes. For example, a process in a mount namespace can have a different file system layout than the host or other namespaces. Kernel namespaces allow containers to have their own network interfaces, process IDs, user IDs, and other resources, without interfering with the host or other containers.
* Control Groups: These are a way of grouping processes and applying resource limits and accounting to them. For example, a control group can limit the amount of CPU, memory, disk I/O, or network bandwidth that a process or a group of processes can use. Control groups allow containers to have a fair share of the system resources and prevent them from exhausting the host resources.
POSIX ACLs and file system permissions are not mechanisms used by LXC and Docker to create containers.
They are methods of controlling the access to files and directories on a file system, which can be applied to any process, not just containers.
