NEW QUESTION # 58
Which functionality is provided by Vagrant as well as by Docker? (Choose three.)

Answer: A,B,D

Explanation:
* Both Vagrant and Docker can share directories from the host file system to a guest. This allows the guest to access files and folders from the host without copying them. Vagrant uses the config.vm.
synced_folder option in the Vagrantfile to specify the shared folders1. Docker uses the -v or -- volume flag in the docker run command to mount a host directory as a data volume in the container2.
* Both Vagrant and Docker can download required base images. Base images are the starting point for creating a guest environment. Vagrant uses the config.vm.box option in the Vagrantfile to specify the base image to use1. Docker uses the FROM instruction in the Dockerfile to specify the base image to use2. Both Vagrant and Docker can download base images from public repositories or local sources.
* Both Vagrant and Docker can apply changes to a base image. Changes are modifications or additions to the base image that customize the guest environment. Vagrant uses provisioners to run scripts or commands on the guest after it is booted1. Docker uses instructions in the Dockerfile to execute commands on the base image and create a new image2. Both Vagrant and Docker can save the changes to a new image or discard them after the guest is destroyed.
* Vagrant and Docker differ in how they start system images. Vagrant starts system images as virtual machines by default, using a provider such as VirtualBox, VMware, or Hyper-V1. Docker starts system images as containers by default, using the native containerization functionality on macOS, Linux, and Windows2. Containers are generally more lightweight and faster than virtual machines, but less secure and flexible.

Answer: C


NEW QUESTION # 60
After creating a new Docker network using the following command:
docker network create --driver bridge isolated_nw
which parameter must be added todocker createin order to attach a container to the network?

Answer: A


NEW QUESTION # 61
Which utility is used to create and manage virtual machine disk images in Linux?

Answer: A

Explanation:
In Linux-based virtualization environments,qemu-imgis the standard utility used to create, convert, inspect, and manage virtual machine disk images. Virtualization and containerization documentation clearly identifies qemu-img as a core component of theQEMU/KVM virtualization stack. It supports multiple disk image formats such as RAW, QCOW2, VMDK, and VHD, making it highly versatile across different hypervisors and platforms.
The qemu-img tool allows administrators to perform critical disk operations, including creating new disk images, resizing existing images, converting between formats, and checking disk integrity. For example, it is commonly used to createQCOW2 images, which support advanced features like copy-on-write, snapshots, and compression.
Other options listed are incorrect becauseDisk Utilityis a general-purpose storage management tool, VirtualBox Manageris specific to Oracle VirtualBox, andLibvirt Disk Manageris not a recognized standalone utility. Libvirt relies on qemu-img internally for disk image handling.
Official virtualization notes consistently reference qemu-img as theprimary disk image management toolin Linux virtualization environments, especially when working with KVM and libvirt-based systems.


NEW QUESTION # 62
Which of the following statements is true regarding the following output ofxl list:

Answer: D
