This helped me effectively handle both priorities and complete the project within the given timeframe.

Situational Questions

• 4. If a customer reported a slow internet connection, what steps would you take to troubleshoot the issue?
  Answer: I would first ask the customer to restart their modem and router. If the issue persists, I would check the signal and connection strength. If necessary, I would perform a speed test and check for any outages in the area.

  Answer: I would first ensure that the printer is connected to the computer and turned on. If it is, I would check the printer settings and make sure it is selected as the default printer. If the issue still persists, I would check for any error messages or paper jams. If necessary, I would reinstall the printer drivers or escalate the issue to the appropriate team.
• 6. If a customer is experiencing a software malfunction, how would you help them troubleshoot the issue?
  Answer: First, I would ask the customer to provide more information about the problem, such as when it occurs and if there are any error messages.

If the issue persists, I would perform a clean uninstall and reinstall of the software or escalate the issue to the appropriate team.

Technical Questions

• 7. Can you explain the difference between RAM and ROM?
  Answer: RAM (random access memory) is a temporary storage device that holds data and instructions for the computer to access quickly. It is a volatile memory, meaning the data is lost when the computer is turned off. ROM (read-only memory) is a permanent storage device that contains essential instructions for the computer to boot up. It is a non-volatile memory, meaning the data remains even when the computer is turned off.
• 8. How do you troubleshoot a computer that won't turn on?
  Answer: First, I would check if the computer is properly connected to a power source. If it is, I would check if the power supply is functioning correctly. Additionally, I would check for any loose connections, such as the power button or motherboard. If necessary, I would replace the power supply or escalate the issue to the appropriate team.
• 9. What is the purpose of a DHCP server?
  Answer: A DHCP (dynamic host configuration protocol) server assigns IP addresses to devices on a network and manages the distribution of network settings, such as default gateway and DNS server addresses. It allows devices to communicate with each other and access the internet.
