                                      NEW QUESTION # 96
                                      Which command within virsh lists the virtual machines that are running on the current host?

                                      Answer: D


                                      NEW QUESTION # 97
                                      Which functionality is provided by Vagrant as well as by Docker? (Choose three.)

                                      Answer: B,C,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.

                                      NEW QUESTION # 98
                                      When setting up a KVM virtualization host, which one of the following components is NOT required?

                                      Answer: A

                                      Explanation:
                                      When configuring a KVM-based virtualization host, several core components are mandatory to enable and manage virtual machines. According to KVM and virtualization documentation,KVM kernel modulesare essential because they provide hardware-assisted virtualization support within the Linux kernel.QEMUis required to perform hardware emulation and manage virtual machine execution.Libvirtacts as the virtualization management API, enabling centralized and secure control of virtual machines. Additionally, bridgeutilsis commonly required to configure network bridges, allowing virtual machines to communicate with external networks.
                                      However,virshisnot strictly required. Virsh is acommand-line utilitythat interacts with libvirt to manage virtual machines, but it is only amanagement interface, not a core dependency. Virtual machines can still be created and managed using alternative tools such asvirt-manager, Ansible, OpenStack, or custom API- based solutionswithout virsh being installed.
                                      Virtualization documentation clearly distinguishes betweenessential backend components(KVM, QEMU, libvirt) andoptional management tools(virsh). Therefore, while virsh is widely used and highly recommended for administrative convenience, it isnot a mandatory componentfor a functional KVM virtualization host.


                                      NEW QUESTION # 99
                                      What is the typical format for cloud-init configuration files?

                                      Answer: D

                                      Explanation:
                                      Cloud-init configuration files are typically written inYAML (Yet Another Markup Language)format.
                                      Official cloud-init documentation specifies thatcloud-configfiles use YAML syntax, which is human-readable and well suited for declarative configuration.
                                      YAML files allow administrators to define users, packages, services, networking, and commands in a structured and consistent way. While cloud-init can process shell scripts and MIME multipart data, YAML remains thestandard and recommended format.
                                      Thus, the correct answer isD.


                                      NEW QUESTION # 100
                                      Which container orchestration platform is often associated with automated scaling and load balancing?

                                      Answer: A

                                      Explanation:
                                      Kubernetesis the container orchestration platform most strongly associated withautomated scaling and load balancing. According to container orchestration documentation, Kubernetes provides built-in features such as Horizontal Pod Autoscaling, service-based load balancing, self-healing, and declarative deployment models.
                                      Docker Compose and LXC are not orchestration platforms at scale, and while Amazon ECS supports scaling, Kubernetes is the industry-standard platform most commonly referenced for these capabilities.
                                      Therefore, the correct answer isB.
