Which subcommand of virsh opens the XML configuration of a virtual network in an editor in order to make changes to that configuration? (Specify ONLY the subcommand without any parameters.)
When preparing a public machine image for the provisioning of new cloud computing instances, which of the following steps should be done? (Choose TWO correct answers.)
- A . Remove all default users and groups, including root and nobody.
- B . Remove all configuration files from /etc/ that were not manually modified.
- C . Remove all confidential data from the image.
- D . Remove all remote login services (i.e. SSH) from the image.
- E . Remove all private SSH keys from the image.
What is the usual way to gain command line access to computing instances in an IaaS cloud?
- A . By providing a public SSH key to the cloud management system and using the matching private SSH
key to log into the instances. - B . Usually computing instances are accessed through a web frontend and do not allow command line access.
- C . By either telnet or SSH using the credentials of the cloud management system account with administrative privileges.
- D . By using a telnet session with the credentials set and publicized by the creator of the computing instance’s system image.
- E . By using a VNC console which does not require authentication when it is invoked via the cloud management system.
Which CPU flag indicates the hardware virtualization capability on an AMD CPU?
- A . SVM
- B . VIRT
- C . VMX
- D . PVM
- E . HVM
Which of the following tasks are parts of a hypervisor’s responsibility? (Choose TWO correct answers.)
- A . Create filesystems during the installation of new VM guest operating systems.
- B . Provide host-wide unique PIDs to the processes running inside the VMs in order to ease interprocess communication between virtual machines.
- C . Map the resources of virtual machines to the resources of the host system.
- D . Ensure isolation and eliminate any interference between virtual machines.
- E . Manage authentication to network services running inside a virtual machine.
Which of the following statements are true for full virtualization? (Choose TWO correct answers.)
- A . Full virtualization does not require changes to the guest operating systems.
- B . Full virtualization has no performance impact compared to a non-virtualized bare-metal installation on the same machine.
- C . Full virtualization has a severe performance impact and should not be used in production environments.
- D . Full virtualization may be supported by special CPU extensions that provide better performance.
- E . Full virtualization always requires additional software components and cannot be done using Linux only.
Which of the following statements are true regarding hardware based virtualization? (Choose TWO correct answers.)
- A . Hardware based virtualization requires special support in the host system’s hardware which is present in all recent x86-based computers.
- B . Hardware based virtualization implements a whole machine in software and therefore can run virtual machines of a given hardware platform on an arbitrary host system.
- C . Hardware based virtualization relies on the host system’s processor to call the hypervisor when critical instructions are executed by a virtual machine.
- D . Hardware based virtualization is not available on x86-based CPU architectures and requires special virtualization host hardware.
Fill in the blank.
What is the name of the global configuration file for the xl tool stack? (Specify the file name only without any path.)
After the Xen guest configuration file debian.cfg has been created and successfully tested, which
additional action must be performed in order to make this Xen guest start automatically every time the host system boots?
- A . It is necessary to add xendomains_auto = yes to the virtual machine configuration file.
- B . It is necessary to add an entry for debian.cfg to the file /etc/xen/guesttab.
- C . It is necessary to run the command xl autostart debian.cfg.
- D . It is necessary to add a symbolic link to the configuration file in the /etc/xen/auto/ directory. E. It is not possible to use Xen and its tools to start virtual machines automatically.
