How comfortable are you configuring basic forms, processes, and settings within CMDB?
Give specific examples of establishing AND updating services in the CMBD. Because this company is setting up new customers with CMBD and servicing their existing client base who have already implemented it, you should highlight your experience with both.
While you can manually add data to your CMDB, it's hard to ensure accuracy and manually keep your CMBD up to date as your IT environment changes. Focus on detailing your automation experience so that the interviewer knows you can establish great service and are comfortable using automation to populate your CMDB to keep data accurate.
"I consider myself fluent in all forms of Configuration Management. I am comfortable with updating existing data and creating and publishing new data. One of the most important parts of my CMDB process is automation. In integrating the CMDB with all data sources per data mappings, I can leverage existing integrations or build new ones. I have experience with data population using the ETL process and CI automation."
