These tools are invaluable for maintaining system health and predicting potential issues.

Question 6

Explain the difference between an incident, a problem, and a known error.
Answer:
An incident is an unplanned interruption to an IT service or a reduction in its quality. A problem is the underlying cause of one or more incidents, often requiring a deeper investigation. A known error is a problem that has been diagnosed and for which a workaround or permanent solution exists.

Question 7

How do you ensure effective communication during a critical incident?
Answer:
During critical incidents, I establish a clear communication channel, providing regular updates to stakeholders on the status, impact, and expected resolution time. I use clear, concise language, avoiding excessive technical jargon, and ensure all relevant teams are informed. Transparency and honesty are key.

Question 8

What scripting languages do you know, and how have you used them in production support?
Answer:
I am proficient in Python and Bash scripting. I’ve used Python to automate routine tasks like log parsing, report generation, and API interactions for system health checks. Bash scripting has been invaluable for system administration tasks, file manipulation, and deploying small fixes on Linux servers.

Question 9

Describe a time you prevented a major outage.
Answer:
In a previous role, I noticed a gradual increase in database connection errors during off-peak hours through our monitoring tools. Proactively investigating, I discovered a resource leak in a newly deployed microservice. I escalated this, and we rolled back the service before it caused a full system crash during peak usage.

I provided a detailed summary of my findings and the steps already taken, ensuring a smooth handover.

Question 16

What measures do you take to ensure system security in production?
Answer:
I adhere strictly to security best practices, ensuring all access is privileged and logged. I’m vigilant about applying patches, monitoring for suspicious activities, and ensuring configuration compliance. Collaborating with security teams to implement and maintain security controls is also a priority.

Question 17

How do you prioritize multiple incidents simultaneously?
Answer:
I prioritize based on impact and urgency, using a structured approach like an ITIL-based severity and priority matrix. High-impact, critical incidents affecting core business functions take precedence. I communicate clearly about current priorities and expected resolution times for each issue.

Question 18

What is your experience with continuous integration/continuous delivery (CI/CD) pipelines?
Answer:
I’ve worked closely with CI/CD pipelines, primarily from a deployment and monitoring perspective. My role often involves ensuring that deployments are stable, verifying post-deployment health checks, and troubleshooting any issues that arise during the release process.
