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

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

Which two statements are true about the configuration of kdump for capturing a dump image after a kernel crash?

• A.kdumprequires no parameters because it is enabled by default.
• B.Thecrashkernelboot parameter must be added to thekernelline in the/boot/grub.conffile to enablekdump.
• C.kdumpuseskexecto reboot the failed kernel and then captures a dump image.
• D.The memory used forcrashkernelis always at the same physical address.
• E.kdumpuseskexecto boot a second kernel, which then captures a dump image.

Examine these commands and their output:
# mount | grep xfs
/dev/mapper/vg_xfs_xfs1 on /xfs1 typr xfs (rw, quota_
# xfs_quota -x -c 'enable -u' /xfs1
# xfs_quota -x -c 'enable -g' /xfs1
XFS_QUOTAON: Invalid argument
Identify the reason for the "Invalid argument" error.

• A.Project and group quotas cannot be enabled at the same time.
• B.The/xfs1file system is mounted without theuquotaandgquotaoptions.
• C.Group quotas are already enabled.
• D.User and group quotas cannot be enabled at the same time.
• E.The/xfs1file system is mounted without thegquotaoption.

Which statement is true about configuring a nameserver in Oracle Linux?

• A.If it is a secondary nameserver, it must copy zone data from a primary nameserver.
• B.If it is a primary nameserver, it must be an authoritative nameserver for all zones.
• C.It may be authoritative for some zones and cache-only for other zones.
• D.If it is a secondary nameserver, it must be an authoritative nameserver for all zones.
• E.If it is a recursive nameserver, it must be a cache-only nameserver for all zones.

A system has several multipathed devices. Some of them are in use with mounted file systems.
The remaining multipathed devices are unused.
The multipath command with the -F option is issued as shown:
[root@host03 /]# multipath -F
Which statement is true?

• A.Any faulted multipath devices are fixed, causing their faulty paths to be rediscovered if the underlying device is found to be available again. The mounted file system is unaffected.
• B.All multipath mapping are flushed, thus removing theirmpathmappings. The mounted file system is unusable.
• C.The command returns a syntax error because an mpath device name must be supplied as the argument to the-Fswitch.
• D.All multipath mapping except those that are in use are flushed, removing their mappings. The mounted file system is unaffected.
