INDIVIDUAL RESPONSESOBJECTIVE ANALYSIS
Question 1:
Correct
When booting your workstation, you hear a series of audible beeps, and the system
locks up.
What is the FIRST step you should take when troubleshooting this issue?
Answer
Replace the motherboard battery.
Disconnect non-essential peripherals and try to reboot.
Check for dust buildup inside the case.
Correct Answer:
Check the motherboard documentation for POST errors.
Explanation
Every time a workstation boots, it runs a Power-On Self Test (POST) to make sure
that all of the basic hardware in the system is present and functioning correctly. If a
problem is identified during POST, an error is generated, which can be a series of
beeps. You need to check the motherboard documentation to interpret what the
series of beeps represents.
If the motherboard battery fails, the system clock can lose time, or the BIOS/UEFI
settings may reset to their defaults. However, this would not cause the series of
beeps you are hearing when the system boots.
Dust buildup can cause overheating and other symptoms. However, this is not
related to the POST error beeps you are hearing when the system boots.
Disconnecting non-essential peripherals and then rebooting is a troubleshooting step
for resolving a Blue Screen of Death issue and is not related to POST error beeps.

Question 2:
Correct
While running a graphics editing program on your Windows workstation, a screen
suddenly pops up with an error message warning. You note the error message, but
the only way to continue working is to reboot your system.
What is this type of error screen called?
Answer
Correct Answer:
BSoD
HVAC
SPoD
POST
Explanation
You are experiencing a Blue Screen of Death (BSoD). This is a proprietary crash
screen officially known as a stop error or blue screen error. A BSoD happens when
the Windows OS encounters a fatal system error.
An SPoD (Spinning Pinwheel of Death) is the macOS equivalent of a BSoD. In this
case, you are running a Windows system, so an SPoD does not apply.
POST errors are encountered when booting your system (before running Windows)
and do not apply in this scenario.
HVAC stands for Heating, Ventilation, and Air Conditioning. This is the system that
moves air between indoor and outdoor areas in a room. HVAC does not directly
apply to computer systems.

Question 3:
Correct
A clicking noise in your computer has now evolved into a grinding noise. In addition,
you are beginning to see frequent error messages while running software, and your
computer occasionally freezes.
What is the MOST likely cause of these issues?
Answer
A failing video card
A failing internal fan
A failing RAM card
Correct Answer:
A failing hard drive
Explanation
A failing hard drive can cause a clicking noise, which eventually evolves into a
grinding noise. Other indicators are frequent error messages while running software
and your computer freezing (locking up).
While a failing fan can also cause a grinding noise, it does not start out as a clicking
noise. In addition, it probably won't cause application error message.
A failing video card can freeze your screen, but will not normally cause application
errors or produce a grinding noise.
While a failing RAM card may cause issues with applications, it will not produce any
noises.

Question 4:
Correct
When you turn on your workstation, you immediately hear a grinding noise coming
from inside the computer case.
Which of the following are the MOST likely causes of this noise?
Answer
A connector that is not seated properly.
Correct Answer:
Dust buildup that needs to be cleaned.
Correct Answer:
An uneven case surface that causes fan blade and motor noise.
A POST test error message.
A video card that is failing.
Explanation
When you hear a buzzing or grinding noise, the most likely cause is your PC's fan.
There are many things that can cause your fan to make a grinding noise, including
dust buildup that needs to be cleaned and an uneven case surface.
A failing video card may result in a noise from the video card fan, but it will not be a
grinding noise.
A POST test error message can result in a series of beeps or a text message on the
screen, but this error does not cause an audible grinding noise.
A connector that is not seated properly can cause an electrical arch, resulting in
smoke or a burning smell. However, the connector will not produce a grinding noise.

Question 5:
Correct
When you try to boot your computer, it hangs after POST. When you access the
UEFI setup program, you see that the date is several years behind, and the time is
set to 12:01 a.m.
Which of the following is the MOST likely cause of this behavior?
Answer
Correct Answer:
The motherboard battery has failed.
The UEFI firmware is outdated.
The UEFI firmware is corrupt.
A RAM module has become unseated from its socket.
Explanation
The system time and date are managed by the real-time clock (RTC) in the
BIOS/UEFI firmware. If the motherboard battery goes dead, the RTC reverts back to
a default date and time. In addition, the BIOS/UEFI may lose all of its configuration
settings.
While outdated IEFI firmware might cause certain issues, in this scenario, the date
and time issues are most likely caused by a failed motherboard battery.
RAM modules have no direct impact on UEFI settings.

I would like to explore the possibility of using a lighting control system. There are times when office staff works long hours and researchers sometimes need to be in the building on nights and weekends. Often times they leave the lights on which increases my electricity costs. I would like to be able to program the lights on a schedule and if the staff needs to work outside that schedule they could request a change with our maintenance staff ahead of time. Could you please look into this and provide me with some potential options.

Case Study – The New Engineer
Jeff was just hired by GSI, Inc. to be their Environmental and Safety Coordinator. This is Jeff's first position after completing his engineering degree. He had taken a course in safety engineering as part of his studies and felt confident that he could handle the job.
Management at GSI, Inc. has assured him that they are committed to maintaining a safe workplace. They have never had an individual dedicated to this task full-time. They will implement his recommendations if he can justify them.
As Jeff begins to get familiar with the operations, he spends considerable time on the production floor. He notices workers clean their tools before break with a liquid from an unmarked 55-gallon drum. They also use this liquid to clean residue from their skin. They use paper towels to dry their tools and hands, throw these towels in the trash, and head to the break room for a snack and/or smoke.

Problem 3: A small gearing system in your brand-new 3D printer fails as you were printing,
leading to an overload in the motor and a fire in your home. The fire spreads, burning half of
Everglades National Park in the worst environmental disaster in US history.
The printer company blames you! Stating that you must have been misusing the printer some-
how. Use your engineering knowledge to "show those jerks you mean business!"
You investigate and find a serial number on the gears and type it into Google, finding the
company that manufactures the gears. Their website provides some info that this series of gear is
made from AISI 4340 steel and the yield strength is 125 kpsi.
Assuming each gear tooth acts as a small cantilever, prove to the 3D printer company that they
are liable for the fire.

Four months into a six month deployment, you are a solo pilot returning to home base after an uneventful overwatch mission to a non-disclosed desert
location. Your mission was extended 90 minutes requiring at least one additional aerial refuel. The moon has now set. A shift in prevailing winds causes an
infrequently used runway to be active. You are less familiar with the approach to this runway and have only used it during VFR conditions. The instrument
approach plate reveals you will fly a prolonged DME arc taking you out over the unlit desert away from the dimly lit base.
While flying the above instrument approach, you take another look at the approach plate. When you look up again the airfield lights are visible through the
upper portion of your canopy. You did not sense any change in your aircraft attitude. Which of the following best describes what happened while you looked
