Consider the features and capabilities of Kernel-based Virtual Machine (kvm).
Which two statements are correct?

• A.kvm provides a software package called Linux Integration Services (LIS) that provides integration between the OS running in thekvmvirtual machine and the physical host.
• B.kvmis considered both a type-1 and type-2 hypervisor because it turns the Linux kernel into a bare-metal hypervisor but the OS running on the virtualization host is a full OS.
• C.Thekvmhypervisor in Oracle Linux is managed withlibvirtAPI and tools built forlibvirt, such asvirt-managerandvirsh.
• D.kvmis an open source hypervisor, which provides full virtualization with hardware-assisted virtualization. It does not support paravirtualized devices.
• E.There are twokvmmodules: akvmmodule that provides the core virtualization infrastructure and akvm_hwmodule that ensbles x86 hardware virtualization extensions (Intel VT or AMD-V).

You want to create a new LUN, LUN ID =1, on a new target, target ID = 2.
Inspect the current state of targets and LUNs in the output from tgt-admin -s. The output is filtered
to show only target and LUN associations.
[root@EDFAR9P0 init.d]# tgt-admin -s | egrep -i 'target|lun'
Target 1: iqn.2013-03.com.example.mypc:1
LUN information:
LUN: 0
LUN: 1
LUN: 2
LUN: 3
You want to add a new LUN to a new target by using the /iSCSIsharedDisk/physDisk4.img disk image file.
Which two options would you use to do this?

• A.tgt-setup-lun -d /iSCSIsharedDisk/physDisk4.img -n 2
• B.tgtadm -- op new \
  --mode target \
  --tid 2\
  --targetname iqn.2013-03.com.example.mypc:2 \
  --lun 1 \
  --backing-store /iSCSIsharedDisk/physDisk4.img
• C.tgt-setup-lun -t 2
  tgt-setup-lun -d /iSCSIsharedDisk/physDisk4.img -t 2
• D.tgt-admin --op new \
  --mode target \
  --tid 2\
  --targetname iqn.2013-03.com.example.mypc:2
  tgt-admin --op new \
  --mode logicalunit \
  --tid 2 \
  --lun 1 \
  --backing-store /iSCSIsharedDisk/physDisk4.img
• E.tgt-admin -d /iSCSIsharedDisk/physDisk4.img -n 2

Consider the features and capabilities of DTrace in Oracle Linux.
Which two statements are true?

• A.The Linux kernel changes required to support DTrace, and the DTrace kernel module, are available under the GNU GPL license.
• B.DTrace is available on Oracle Linux only on the z86_64 platform.
• C.DTrace package are part of the standard OL distribution, although they are not installed by default.
• D.DTrace is available on all Linux platforms.
• E.DTrace package are available by subscription from the Unbreakable Linux Network (ULN).

Which two statements are true about the cpuset cgroup subsystem?

• A.It reports the total CPU time used by cgroup tasks.
• B.It assigns individual CPUs on a multicore system to cgroup tasks.
• C.It controls CPU scheduling according to relative CPU shares of cgroup tasks.
• D.It assigns individual CPUs and memory nodes for NUMA-enabled architectures to cgroup tasks.

Which three statements are true about the crash utility in Oracle Linux?

• A.It can analyze only dumps produced by thekdumpfacility.
• B.Thekernel-debuginfoandkernel-uek-debuginfopackages are not included in the Oracle Linux distribution.
• C.It can analyze the state of the system after a kernel crash has occurred by using the memory image file produced from the crash.
• D.It can analyze only dumps produced by theLinux Kernel Crash Dumps (LKCD)facility.
• E.It can analyze the state of the system while it is running.
