Oracle Linux 6 Advanced System Administration: 1Z0-105

Examine the virt-install command.

# virt-install \

--connect qemu:///system \

--virt-type kvm \

-- name test \

-- ram 500 \

--disk path =/var/lib/libvirt/images/test.img, size=4

--cdrom /home/user01/DownLoads/OracleLinux-R6-U5-Server-x86_64-dvd.iso \

--os-variant oe16

Which two statements are true?

A. The --connect option specifies the credentials for the hypervisor to use.

B. The --name option specifies the name of the new guest virtual machine instance.

C. The --ram option specifies the memory to allocate for a guest instance in MB.

D. The --virtype option specifies that only the keyboard, video, and mouse are fully virtualized.

E. The --disk option specifies the media to use as storage for the guest. The size of the storage will be 4 GB.

Examine the dtrace command:

dtrace n syscall::read:entry

Which two statements are true?

A. This statement fails with a syntax error because no action is defined.

B. This statement runs successfully with the default action being executed.

C. The probe name is read.

D. The probe name is entry.

E. The probe name is not specified in this command, but it is implied through adjacent colons.

F. This command runs but produces no output; is no predicate to select when the probe fires.

A SAN is configured with multiple physical paths to each device for each client system.

For a specific client, only a subset of visible devices requires management by Device Mapper Multipath. The device in question is visible as /dev/sdf and /dev/sdh to that client.

Examine the code fragment from /etc/multipath.conf that is proposed configuration to solve the problem:

Which statement is true?

A. The proposed configuration does work but should not be used due to problems with device name persistence across reboots.

B. The proposed configuration does not achieve the desired result because you cannot override blacklist entries using different identifier types.

C. The proposed configuration does not achieve the desired result because the second path (/dev/sdh) is not referenced in blacklist_exceptions.

D. The proposed configuration achieves the desired result. /dev/sdf and implicity its second path (/dev/ sdh) are grouped into a multipath device.
