Question 3
Which of the following tasks is performed by Vagrant?
- It migrates virtual machines automatically between host systems to distribute the load of all virtual machines equally to all hosts involved.
- It automates the installation of a virtual machine according to a configuration file describing the desired VM.
- It monitors the functionality of a virtual machine and restarts the VM in case of failure.
- It is a hypervisor optimized for the usage in embedded systems based on the ARM CPU architecture.
- It is a programming interface used to create reports from collected performance and resource usage data of a libvirt-based virtualization infrastructure.
Correct answer: B

Question 9
Which of the following tasks are parts of a hypervisor's responsibility? (Choose TWO correct answers.)
- Create filesystems during the installation of new VM guest operating systems.
- Provide host-wide unique PIDs to the processes running inside the VMs in order to ease interprocess communication between virtual machines.
- Map the resources of virtual machines to the resources of the host system.
- Ensure isolation and eliminate any interference between virtual machines.
- Manage authentication to network services running inside a virtual machine.
Correct answer: CD
Explanation:
Question 10
Which of the following statements are true for full virtualization? (Choose TWO correct answers.)
- Full virtualization does not require changes to the guest operating systems.
- Full virtualization has no performance impact compared to a non-virtualized bare-metal installation on the same machine.
- Full virtualization has a severe performance impact and should not be used in production environments.
- Full virtualization may be supported by special CPU extensions that provide better performance.
- Full virtualization always requires additional software components and cannot be done using Linux only.
Correct answer: AD
