COURSE CAREERS PRACTICE EXAM 2025/2026 QUESTIONS
AND SOLUTIONS MARKED A+
✔✔If a customer calls in saying their PC is slow, how would you address the problem? -
✔✔I would first ask if the customer has noticed when the PC is slow and if there are any
specific programs causing the issue. Then, I'd guide them through closing unnecessary
programs, checking for malware, and running a disk cleanup. I'd also suggest checking
their startup programs and updating drivers. If the problem continues, I'd recommend
further troubleshooting or escalate it if needed.
✔✔A caller reports that their monitor has blacked out. How would you troubleshoot? -
✔✔I would first ask if the monitor is powered on and if the cables are securely
connected to both the monitor and the PC. Then, I'd have them try using a different
cable or port to rule out any hardware issues. I'd also check if the brightness is set too
low or if the display settings are correct. If these steps don't resolve the issue, I'd
recommend testing the monitor with a different device or escalating the ticket for further
assistance.
✔✔Walk us through the steps of adding a new printer to a user's network. - ✔✔To add a
new printer, I would first make sure the printer is turned on and connected to the
network. Then, I'd install the printer drivers if needed and go to the Printers & Scanners
settings to add the printer. After that, I'd set it as the default printer if necessary and
print a test page to make sure it works. Finally, if needed, I'd enable printer sharing.
✔✔What is a VPN? - ✔✔A VPN (Virtual Private Network) is a service that creates a
secure, encrypted connection between your device and the internet. It helps protect
your privacy by masking your IP address and making your online activities harder to
track, especially when using public Wi-Fi networks.
✔✔What is your home network like? - ✔✔My home network consists of a router
connected to the internet, providing Wi-Fi for all my devices, including laptops,
smartphones, and smart home devices. I also have a few wired connections for devices
that require a more stable connection, like my desktop and printer. To ensure security, I
use strong passwords and enable encryption on the Wi-Fi network.
✔✔What is the difference between a router and a switch? - ✔✔A router connects
different networks, like your home network to the internet, and directs data between
them. A switch, on the other hand, connects devices within the same network, allowing
them to communicate with each other by directing data to the correct device.
✔✔What is an IP Address? - ✔✔An IP address (Internet Protocol address) is a unique
identifier assigned to each device connected to a network. It allows devices to
communicate with each other over the internet or a local network by directing data to
the correct location.
, ✔✔What languages have you programmed in? - ✔✔sql, python,java,html csss,
javascript and bash script
✔✔Tell me about the most recent project you worked on. What were your
responsibilities? - ✔✔I worked on a project where users could upload their PDF books
and take notes. My responsibility was to create the front-end, designing and
implementing the user interface to make it easy for users to upload books and add their
notes. I worked closely with the team to ensure the front-end was functional and user-
friendly.

✔✔Three tickets come in at the same time: CEO's personal iPad is slow and he is very
mad, 5 people in accounting are suddenly missing important software to do their job,
and the customer facing e-commerce site is down. Describe how you would prioritize
these tickets. - ✔✔I would prioritize the tickets based on urgency. First, I would fix the
customer-facing e-commerce site since it affects the company's revenue. Next, I would
help the accounting team with their missing software, as it impacts multiple people.
Finally, I would address the CEO's slow iPad, as it's important but not as urgent as the
other issues.
✔✔Your department is performing a hardware refresh of 1000 laptops where
performance/speed of the systems is paramount. Your manager asks you to decide
between 1TB HDDs and 500GB SSDs for the department. Both drives are the same
price. Which do you choose and why? - ✔✔I would choose the 500GB SSDs because
they offer significantly better performance and speed compared to 1TB HDDs. SSDs
have faster read and write speeds, which would greatly improve the overall system
performance, especially for tasks requiring quick access to data. Since performance
and speed are paramount, the SSDs would provide a better user experience despite the
smaller storage size. Additionally, users can always rely on cloud storage or external
drives if more space is needed.
✔✔What are the 7 layers of the OSI Model? - ✔✔Application Layer . Presentation
Layer, Session Layer. Transport Layer. Network Layer. Data Link Layer. Physical Layer.
✔✔What is a situation where you would use SSH? What port does SSH operate on? -
✔✔SSH (Secure Shell) is commonly used to securely access and manage remote
servers or devices over a network. For example, you would use SSH to log into a
remote server to perform administrative tasks, like updating software or configuring
settings. SSH operates on port 22 by default.
✔✔Describe any experience you have with remote assistance tools - ✔✔I have
experience using remote assistance tools like TeamViewer, AnyDesk, and Remote
Desktop Protocol (RDP). These tools allow me to remotely access and troubleshoot a
user's computer, fix issues, or guide them through solutions. I've used them to provide
