How knowledgeable are you with some of the more popular programming languages, such as C++, Java, and Python?

IT engineers are not expected to program or create software. However, it is a benefit if you can do this. You should at least have some familiarity with popular programming languages and be able to discuss their benefits and applications. Interviewers for IT Engineer roles at Cisco will ask you about this to determine your knowledge of software development languages and confirm that you will collaborate with the Cisco development team to ensure the software will function well within the IT infrastructure you will help manage.
