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.

Question 6:
Correct
Which pin on the power supply connector connects to the power good wire on the
motherboard in order to indicate an appropriate action for the motherboard if the
power disappears, quickly reappears, or does not appear at all?
Answer
Pin 5
Pin 2
Correct Answer:
Pin 8
Pin 6
Explanation
Pin 8 on the power supply connector connects to the power good wire on the
motherboard.
If power disappears from this wire, the motherboard shuts down.
If power quickly reappears on this wire, the system may attempt to come
back on by itself, resulting in continual reboots.
If power does not reappear on this wire, the system shuts off.

Question 7:
Correct
An employee calls to complain that their computer is behaving erratically. Some
days, it functions correctly, and other days, it crashes frequently. Sometimes, the
system won't boot at all.
You open the system case and notice the following:
Two of the mounting screws are missing from the system hard disk drive.
The system uses memory modules from several different manufacturers
with mismatched capacities.
Several capacitors on the motherboard are bulging and have a brown
liquid oozing from them.
The chassis fan on the front of the case is oriented to blow air into the
system.
What should you do?
Answer
Reorient the chassis fan to draw air out of the system case.
Replace the leaky capacitors on the motherboard.
Use additional screws to mount the hard disk drive to the system case.
Correct Answer:
Replace the motherboard.
Replace the existing memory modules with matching modules.
Explanation
The motherboard in this scenario has distended capacitors. This is evidenced by
their bulging shape and the brown fluid leaking from them. The best way to solve this
issue is to replace the entire motherboard.
The fan in this scenario is pushing air in the correct direction.
Installing matching memory modules may improve system performance, but this will
not remediate the system's instability problem.
Using additional mounting screws on the hard disk drive will not improve system
stability.
Replacing individual leaking capacitors on the motherboard is extremely difficult and
could further damage the motherboard.

Question 8:
Incorrect
When playing videos games or watching movies on your workstation, the screen
sometimes freezes and displays strange colors. You suspect that your video card is
causing the issues.
What is the BEST solution to resolve your display issues?

Answer
Check the video card fan.
Check the video card connectors.
Incorrect answer:
Update the video card driver.
Correct Answer:
Replace the video card.
Explanation
The best remedy is to replace the video card because it will fail completely at some
point.
While updating the video card driver may resolve the display issues for now, it is
more likely that your video card is failing. The best solution is to simply replace the
video card.
If the video card has been working properly until now, it is highly unlikely that you
have a loose video card connector.
If you are not hearing any noise from the fan while it is spinning, it is highly unlikely
that the fan is the cause of the display issues.

Question 9:
Correct
After arriving at work, you turn on your computer to begin your day. Instantly, you see
smoke and smell a strange odor coming from the computer.
Which of the following would be the MOST important action to take first?
Answer
Correct Answer:
Shut off the system immediately.
Call the IT director.
Log in and check Event Viewer.
Open the computer case and look for dust buildup.
Explanation
If you see smoke or smell something burning, shut off the system immediately to
prevent further damage and the chance of a fire hazard.
Event Viewer shows past system events and error messages, but this function would
not help in this scenario.
While calling the IT director might be your next step, your first step should be to shut
off the system.
While inspecting your computer, you should look for dust buildup on components and
clean them as necessary. However, inspecting for dust buildup is not the first step
you should take in this scenario.

Question 10:
Incorrect
While performing data entry on your Windows 11 laptop, your screen suddenly goes
black.
What can you do immediately to troubleshoot the issue without losing any data that
you have entered?
Answer
Incorrect answer:
Press
Ctrl
+
Shift
+
B
Press
Ctrl
+
Alt
+
Del
Press
F5
four times
Correct Answer:
Press the
Windows
key
+
P
four times
Explanation
If your screen suddenly goes black, try using the
Windows
key
+
P
four times to
switch between the four different display modes to see if the black screen
disappears.
Pressing
Ctrl
+
Shift
+
B
resets the video driver in Windows 10 and can be useful
when encountering a black screen. However, this is a Windows 11 laptop.
Pressing
Ctrl
+
Alt
+
Del
lets you terminate an application task or reboot the
operating system. However, in this scenario, you probably want to check the display
first before terminating applications or rebooting the system.
Pressing
F5
refreshes the screen, which will probably not resolve your black screen
issues. In addition, pressing
F5
may cause the data entry software to close, causing
you to lose your data.

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.

You are an engineer working on a project and your prototype has failed prematurely. You question whether or not a key component of the prototype was manufactured with the correct material. There are two way to check for the material properties. The first way is to have a material certification done to confirm the exact material composition. This will take some time. The second method to confirm the material properties is to make an ASTM test sample and test for the material properties. This tensile test was completed on a test sample with an initial diameter of .501” and an initial length of 2”. The Load-Deflection data for this tensile test is below. Use this data to answer the first set of questions on the Final Exam in eLearning. A. Determine the Ultimate Tensile Strength B. Determine the 0.2% Offset Yield Strength C. Determine the value of the Proportional Limit D. Determine the Modulus of Elasticity E. Determine the Strain at Yield F. Calculate %…

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.
