Role and Technical Knowledge

1. 1

   What is the difference between an incident and a problem in ITIL?

   Explain that an incident is an unplanned interruption, while a problem is the root cause of one or more incidents. Mention that incident management focuses on restoring service quickly, whereas problem management aims to prevent recurrence.

2. 2

   How would you troubleshoot a user who cannot access the internet?

   Walk through a logical sequence: check physical connections, ping localhost, ping gateway, check DNS resolution, and verify IP configuration. Emphasize documenting each step and asking the user clarifying questions.

3. 3

   What are the key components of an SLA in a support role?

   Cover response time, resolution time, uptime guarantees, and escalation procedures. Explain how SLAs vary by severity level and how breaching them impacts the client relationship.

4. 4

   Explain the difference between TCP and UDP with a support example.

   State that TCP is connection-oriented and reliable, used for web browsing and email, while UDP is connectionless and faster, used for streaming or VoIP. Give a scenario where choosing the wrong protocol could cause support issues.

Practical Scenarios

1. 5

   A critical application is down for multiple users, but you are already handling another high-priority ticket. What do you do?

   Show prioritization based on impact and urgency, suggest informing your supervisor or team lead, and possibly reassigning or seeking help. Highlight communication with affected users and following escalation matrix.

2. 6

   A user is frustrated and angry about a recurring issue. How do you handle the call?

3. 7

   You suspect a security breach, such as a phishing email clicked by a user. What steps do you take?

   Immediately isolate the affected system, report to the security team as per policy, and preserve evidence. Do not try to fix it yourself beyond initial containment. Mention following incident response protocols.

4. 8

   How would you handle a ticket that requires a change to the production environment?

   Explain that changes must go through change management, requiring approval and scheduling. You would raise a change request, assess risk, and ensure a rollback plan. Never make unauthorized changes.
