Actual exam question from CompTIA's 220-1002

Question #: 188
Topic #: 1

A technician responds to a report that a user's desktop is operating much slower after upgrading the Windows OS to the latest version. The technician notices responsiveness is erratic, and the symptoms are similar to a failing hard drive. The technician runs a full hardware diagnostic, and all systems pass. The technician checks the properties for each device in Device Manager and the hard disk and the standard AHCI 1.0 serial ATA controller both indicate the following message: This device is working properly. Which of the following should the technician attempt that will MOST likely resolve the performance issue?

A. Roll back the OS upgrade. Continue using the older version of Windows
B. Reset the PC to its factory conditions. Perform the OS upgrade again
C. Update the SATA controller driver from the manufacturer's website
D. Perform a full backup and replace the hard drive

C. Update the SATA controller driver from the manufacturers website -- always start with the quickest and least expensive potential solution -- if that fails then move to the next best solution.

The question clearly mentions that both hard disk and AHCI SATA are working properly, so why not rollback?

Why not A? Everything about the computer seems to be working fine until the OS was upgraded. The question is asking how to resolve the Performance issues not what is the quickest or cheapest way to fix the issue. Rolling back to the previous OS would most likely resolve the Performance issues.

But why waste time rolling back on something that can potentially be fixed quickly and easily anyway? OS upgrades are inevitable and will need to happen sooner or later. Might as well try to fix the issue, rather than revert what eventually needs to be done.

This is all about the phrasing of the question. The question mentions two things that indicate the drive is not failing, this is on purpose. From the data provided the drive itself is fine, replacing it would do nothing. So the answer is C.

Upon further consideration: B. Reset the PC to its factory conditions. Perform the OS upgrade again – the tech has not identified the problem – everything the tech checked reports no errors – he just observes that “responsiveness is erratic” – so reset and re-upgrade.

Unnecessary when the next best troubleshooting step (C.) takes far less time and effort.

Bah, years of being trained to "before you do ANYTHING, back it up!" is gonna cause me to fail

Though I suppose the real devil in the details here is "full backup", that'd take WAY too long for a regular support call

The answer doesn't make sense for this question. Shouldn't it be D. Run a Full Back-up and replace the Hard Drive?

Try updating the driver is quick and free. Lowest impact/cost method first.

The question asks "...will MOST likely RESOLVE the performance issue" not what should be the first thing to try. The first thing to try might be the driver, but it's not likely to be the thing which RESOLVES the problem.

It's C because the question mentions that more than one thing indicates that the drive is not failing. Replacing the drive when the drive isn't faulty would potentially keep the issue. If the drive was indicated failing then replacing the drive would be most likely.

It is so likely. The problem is with the drive and after been proven to not be failing, the drivers would most likely be the culprit. Would you reinstall Windows every time your printer fails to print? No, you would update or reinstall the printer driver if the spooler service is not causing the issue.
