Users complain that system performance is unacceptable when using a specific application service running on a multiprocessor service.

You have established from the storage team that disk response times have not increased, so you can discount there being an I/O problem.

You run vmstat to look at CPU activity and notice high average disk times on the multiprocessor system and an average run queue of zero.

You require more detail about each CPU from which the vmstat figures are derived, to investigate if the load is distributed evenly across all CPUs.

Which three commands provide more detailed information about CPU load distribution?

A. iostat x

B. top

C. mpstat

D. vmstat

E. sar

A. It contains kernel parameter files.

B. It contains metadata on all block devices.

C. It contains metadata on firmware.

D. It contains metadata on all loaded modules in the kernel.

E. It contains metadata on device classes.

F. It contains metadata on system uptime.

Examine these configuration files: # cat /etc/auto.master /net -hosts /- auto.direct ro

# cat /etc/auto.direct

/nfs1 o16:/export/share1 /nfs2 -sync o16:/export/share2 /nfs o16:/export/share3

Which mount options will automounter use to mount the filesystems listed in /etc/auto.direct?

A. All three filesystems are mounted read-only, async.

B. /nfs1 and /nfs3 are mounted read-only, async whereas /nfs2 mounted read-write, sync.

C. /nfs1 and /nfs3 are mounted read-only, async whereas /nfs2 mounted read-only, sync.

D. All three filesystems are mounted read-write, sync.

You must remove a Physical Volume (PV) from a Volume Group (VG) containing one Logical Volume (LV) without compromising data availability.

What must you do before using the vgreduce command, to remove the PV?

A. Move allocated physical Extents (PE) from /dev/sdd to other physical volumes using the pvmove command.

B. Remove the /dev/sdd PV using the pvremove command.

C. Resize the /dev/sdd PV to zero using the pvresize command.

D. Move allocated physical Extents (PE) from /dev/sdd to other physical volumes by using the 1vvonvert

-replace command.
