1. Question: Can you explain the concept of IP addressing? (100% asked Technical Support Interview Questions )
Answer:
IP addressing is like a postal address for devices on a network. It helps in identifying and routing data to the right destination. There are two types: IPv4 (e.g., 192.168.1.1) and IPv6 (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
2. Question: How would you troubleshoot a user unable to connect to the internet?
Answer:
I would start by checking if the user is connected to the correct network and if other devices have internet access. If it’s only their device, I’d have them restart the router and device, check for any proxy settings, and ensure the correct Wi-Fi password is entered.
3. Question: What’s the difference between HTTP and HTTPS? (80% asked Technical Support Interview Questions )
Answer: HTTP (Hypertext Transfer Protocol) is unsecured, while HTTPS (Hypertext Transfer Protocol Secure) encrypts data for secure communication. For example, when you shop online, HTTPS ensures your credit card info is safe.
4. Question: Explain the term “driver” in the context of computer hardware.
Answer:
A driver is software that allows an operating system to communicate with hardware devices. For instance, a graphics card driver helps the OS understand how to utilize the graphics card’s capabilities effectively.
5. Question: What’s a firewall and how does it work? (80% asked Technical Support Interview Questions )
Answer:
A firewall is like a security gate that filters incoming and outgoing network traffic. It decides what data packets are allowed or blocked based on predefined rules. Imagine it as a bouncer at a club, letting in only authorized guests.
6. Question: Describe a DNS server and its purpose.
Answer:
A DNS server translates human-readable domain names (like www.example.com) into IP addresses (like 192.0.2.1). It’s like a phone book for the internet, helping your browser find the correct server for the website you want to visit.
7. Question: What steps would you take to troubleshoot a slow computer?
Answer:
I would check for background applications consuming resources, run a malware scan, clean up temporary files, and ensure the operating system and drivers are up to date.
8. Question: Explain what RAID is and its different levels. ( 100% asked Technical Support Interview Questions )
Answer:
RAID (Redundant Array of Independent Disks) is a technology that combines multiple hard drives for improved performance, data redundancy, or both. RAID 0 offers performance by striping data, while RAID 1 provides redundancy by mirroring data.
9. Question: How do you handle a situation where a user forgets their password?
Answer:
I would guide the user to the password reset process. Usually, this involves clicking on a “Forgot Password” link, answering security questions, and receiving a password reset link via email.
10. Question: Can you differentiate between RAM and hard disk storage?
Answer:
RAM (Random Access Memory) is temporary memory that stores data for active programs, enabling fast access. Hard disk storage, on the other hand, is permanent and stores files, even when the computer is turned off.
11. Question: What’s the purpose of an operating system?
Answer:
An operating system (e.g., Windows, macOS) manages hardware and software resources, facilitates communication between software and hardware, and provides a user interface. It’s like the conductor of an orchestra, coordinating everything.
12. Question: Explain the term “latency” in networking.
Answer:
Latency is the delay between sending a data request and receiving a response. It’s like the time it takes for a friend to respond to your text message.
Answer:
I would check if the monitor is powered on, the cables are connected properly, and the computer is running. If everything seems fine, I might try connecting the monitor to another device to ensure it’s working.
14. Question: What’s a subnet mask used for?
Answer:
A subnet mask helps define the range of IP addresses within a network. It works like a filter, separating the network and host portions of an IP address. For instance, in 192.168.1.0/24, the subnet mask is 255.255.255.0.
15. Question: Explain the concept of virtualization.
Answer:
Virtualization allows you to run multiple virtual machines (VMs) on a single physical machine. Each VM acts like a separate computer, enabling efficient use of hardware resources. It’s like having multiple rooms within a single house.
16. Question: What’s the difference between a switch and a router?
Answer:
A switch connects devices within the same local network, like connecting computers in an office. A router connects different networks, like your home network to the internet.
17. Question: Describe a DoS (Denial of Service) attack.
Answer:
A DoS attack floods a network or server with an overwhelming amount of traffic, causing it to become slow or unavailable. It’s like hundreds of cars converging on a single road, causing a traffic jam.
18. Question: How does data encryption work?
Answer:
Encryption converts data into a code to prevent unauthorized access. Imagine sending a secret message using a code that only the recipient knows how to decode.
19. Question: What’s the importance of regular software updates?
Answer:
Regular updates fix bugs, improve performance, and patch security vulnerabilities. They’re like getting tune-ups for your car to keep it running smoothly and safely.
20. Question: Explain the role of a cache in computing.
Answer:
A cache stores frequently used data for quick access, reducing the need to retrieve it from slower storage locations. It’s like keeping your favorite snacks on your desk for easy munching, instead of going to the kitchen every time.
