• Update Knowledge Base: If the issue is a new one or the solution could be useful for others, I contribute to the organization’s knowledge base or FAQ section.

I use support ticket systems like Zendesk or ServiceNow to manage and maintain logs, as these platforms offer excellent tools for categorization, searchability, and reporting. Accurate documentation helps in tracking recurring issues, improving support practices, and providing valuable insights for IT infrastructure improvements.

12. Can you explain what DNS is and why it might cause a computer not to have internet access? (Networking & Knowledge)

DNS, or Domain Name System, is a critical component of the internet’s functionality. It acts as the internet’s phonebook, translating human-friendly domain names like www.example.com into IP addresses that computers use to identify each other on the network.

DNS issues might prevent a computer from accessing the internet for several reasons:

• DNS Server Unavailability: If the DNS servers are down or unreachable due to network problems, the computer cannot resolve domain names, resulting in an inability to access websites.
• Incorrect DNS Configuration: If the DNS settings on the computer are incorrect, it may be directed to a non-functioning DNS server.
• DNS Cache Corruption: The DNS cache on the computer stores recently visited domain name resolutions. If this cache becomes corrupt, it can lead to resolution errors and connectivity issues.
• Malicious DNS Changes: Malware or unauthorized users can change DNS settings to redirect traffic to malicious sites, which can also disrupt normal internet access.

13. How would you manage a situation where you need to support multiple users at the same time? (Multitasking & Customer Service)

How to Answer:
When answering this question, it’s important to convey that you can handle pressure effectively while maintaining your organizational skills. Specify any techniques or tools that you use to manage stress and stay organized. Employers want to ensure you can maintain productivity and make rational decisions under stress.

Example Answer:
In high-pressure situations, I primarily focus on three things: prioritization, communication, and mindfulness.

• Prioritization: I create a list of tasks based on urgency and importance. This helps me to focus on what needs to be addressed immediately and what can wait.
• Communication: I ensure that I’m in constant communication with my team and supervisors. This helps to manage expectations and to seek help when required.
• Mindfulness: I practice mindfulness and take short breaks to clear my head. This prevents burnout and keeps me calm, allowing for better decision-making.

Additionally, I use tools like ticketing systems to keep track of issues and their statuses, and I maintain a clean workspace which helps reduce physical clutter and by extension, mental clutter.

22. How familiar are you with scripting and automation to streamline desktop support tasks? (Technical Skills & Automation)

I am quite familiar with scripting and automation in the context of desktop support. Automating routine tasks can greatly improve efficiency and reduce the risk of human error. I have experience with the following:
