30 Server Technician Interview Questions With Sample Answers
1. What is a server?
A server is a computer or system that provides resources, data, services, or programs to other computers, known as clients, over a network.
2. What are the different types of servers?
- Web Server: Hosts websites and serves web pages to users.
- File Server: Stores and manages files for network users.
- Database Server: Provides database services to applications.
- Mail Server: Manages and routes emails.
- Application Server: Hosts applications and facilitates a user’s access to them.
3. What is RAID, and why is it used?
RAID stands for Redundant Array of Independent Disks. It is used to combine multiple hard disks into a single unit to improve performance, ensure data redundancy, and increase fault tolerance.
4. Explain the difference between SSD and HDD.
- SSD (Solid State Drive): Uses flash-based memory for faster data access, no moving parts, and is more durable.
- HDD (Hard Disk Drive): Uses spinning disks to read/write data, typically slower, and has moving parts making it more prone to failure.
5. What is virtualization?
Virtualization is the creation of virtual (rather than physical) versions of servers, storage devices, or network resources, allowing for more efficient utilization of hardware.
6. How do you troubleshoot network connectivity issues?
- Check physical connections (cables, switches).
- Use the “ping” command to test connectivity.
- Check IP configurations.
- Look for firewall or security settings blocking access.
7. What is DHCP?
DHCP (Dynamic Host Configuration Protocol) is a network management protocol that automatically assigns IP addresses and other network configuration parameters to devices on a network.
8. Describe what DNS is.
DNS (Domain Name System) translates domain names (like www.example.com) into IP addresses that computers use to communicate with each other.
9. What is an IP address?
An IP address is a unique identifier assigned to each device connected to a network, allowing it to communicate with other devices.
10. How can you secure a server?
- Implement firewalls.
- Use strong passwords and change them regularly.
- Regularly update software and apply patches.
- Ensure data encryption and backups.
11. What are the benefits of using Active Directory?
Active Directory allows for centralized management of users, computers, and policies within a Windows domain, enhancing security and administrability.
12. What is the purpose of a VPN?
A VPN (Virtual Private Network) provides a secure connection over the internet, allowing users to access private networks remotely while ensuring data integrity and privacy.
13. What is a subnet mask?
A subnet mask is a 32-bit number that divides an IP address into the network and the host portions, determining which part of the address identifies the network and which part identifies the device.
14. How do you monitor server performance?
Utilize monitoring tools to track CPU usage, memory usage, disk I/O, and network activity. Performance metrics can be analyzed through logs and alerts.
15. What is a load balancer?
A load balancer distributes network or application traffic across multiple servers, ensuring no single server becomes overwhelmed and improving performance and reliability.
16. How do you perform a system backup?
Backups can be scheduled using backup software to create full, incremental, or differential backups of system files, databases, and configuration settings.
17. Explain what a proxy server is.
A proxy server acts as an intermediary for requests from clients seeking resources from other servers, often used for security, anonymity, and content filtering.
18. What is SSH?
SSH (Secure Shell) is a cryptographic network protocol for secure remote access and management of networked devices and servers.
19. What do you understand by server hardening?
Server hardening is the process of securing a server by reducing its surface of vulnerability, often achieved through disabling unnecessary services, applying updates, and enforcing security policies.
20. How do you handle server outages?
Identify the cause through systematic troubleshooting, communicate with affected users, implement a fix, document the issue, and review processes to prevent future occurrences.
21. What is system imaging?
System imaging creates a complete snapshot of a system’s operating environment at a certain point in time, allowing for easy restoration in case of failures.
22. How would you set up a new server?
- Choose appropriate hardware/software.
- Install the operating system.
- Configure network settings and services.
- Implement security measures.
- Test server functionality.
23. What is the difference between a hardware firewall and a software firewall?
- Hardware Firewall: A physical device that filters traffic between the network and the internet, providing a first line of defense.
- Software Firewall: A program installed on a computer that controls incoming and outgoing traffic based on predetermined security rules.
24. Explain the process of patch management.
Patch management involves identifying, acquiring, installing, and verifying patches to software and systems to protect against vulnerabilities and ensure stability.
25. What are some common server operating systems?
- Windows Server
- Linux (various distributions like Ubuntu, CentOS)
- Unix
- macOS Server
26. How would you prioritize tasks during an outage?
Assess the impact on business, identify critical systems and services, and address those first while communicating status updates to stakeholders.
27. What is a content delivery network (CDN)?
A CDN is a network of servers distributed geographically to store cached versions of content close to users, improving load times and reducing latency.
28. What is backup validation, and why is it important?
Backup validation is the process of confirming that data backups are complete and can be restored effectively. It is crucial to ensure data integrity and reliability for disaster recovery.
29. What tools do you use for server management?
Common tools include:
- Remote Desktop Protocol (RDP)
- PuTTY (for SSH)
- Windows Server Manager
- Linux command-line tools (SSH, scp, etc.)
30. How do you stay updated with the latest technology trends?
Regularly read tech blogs, participate in online forums, attend webinars, and engage in professional training and certification programs to stay abreast of advancements in server technology.
