Correct Answer: B

Package Selection Options include:

-f [file]

Query package owning [file]

Note:

rpm -q -- What does it do?

One of the nice things about using RPM is that the packages you manage don't end up going into some

kind of black hole. Nothing would be worse than to install, upgrade, and erase several different packages

and not have a clue as to what's on your system. In fact, RPM's query function can help you get out of

sticky situations like:

*

You're poking around your system, and you come across a file that you just can't identify. Where did it come from?

*

Your friend sends you a package file, and you have no idea what the package does, what it installs, or where it originally came from.

*

You know that you installed XFree86 a couple months ago, but you don't know what version, and you can't find any documentation on it.

The list could go on, but you get the idea. The rpm -q command is what you need. If you're the kind of person that doesn't like to have more options than you know what to do with, rpm -q might look imposing. But fear not. Once you have a handle on the basic structure of an RPM query, it'll be a piece of cake.

Use the sar -q command to report the following information:

The Average queue length while the queue is occupied.

The percentage of time that the queue is occupied.

*

The following list describes the output from the -q option.

runq-sz The number of kernel threads in memory that are waiting for a CPU to run. Typically, this value should be less than 2. Consistently higher values mean that the system might be CPU-bound.

%runocc

The percentage of time that the dispatch queues are occupied.

swpq-sz

Swap queue of processes for the sar command.

%swpocc

Swap queue of processes for the sar command.

Correct Answer: B

Example:

kern.* /var/adm/kernel kern.crit @finlandia;RFC3164fmt kern.crit /dev/console kern.info;kern.!err /var/adm/kernel-info

The first rule direct any message that has the kernel facility to the file /var/adm/kernel.

The second statement directs all kernel messages of the priority crit and higher to the remote host finlandia. This is useful, because if the host crashes and the disks get irreparable errors you might not be able to read the stored messages. If they're on a remote host, too, you still can try to find out the reason for the crash.

The third rule directs these messages to the actual console, so the person who works on the machine will get them, too.

The fourth line tells rsyslogd to save all kernel messages that come with priorities from info up to warning in the file /var/adm/kernel-info. Everything from err and higher is excluded.
