Nobody is perfect, even the highly-skilled software engineers Cisco hires. Every software engineer has errors in the code they create. Denying this will be a red flag, which will make the interviewer skeptical of your qualifications. A better approach to answering this question is to acknowledge that you make errors and have a process you use to identify and correct them.

"After I create a segment of code, I take several steps to identify any errors and debug them. These include wrapping the code, using try/catch statements, and using various debugging tools. Once the entire program has been completed, I ask either my peers or the quality control team to review the code and identify any errors I may have missed."
