This course is designed for anyone who performs or seeks to perform a developer role and has one or more years of hands-on experience developing and maintaining applications that are built on top of Cisco platforms. The course is appropriate for software developers, application developers, and network engineers who want to expand their skill base and validate their skills in programmability, software, and automation. Students preparing for Cisco Certified DevNet Associate certification will also find this material useful. The job roles best suited to the material in this course are:

• Network automation engineer
• Software developer
• System integration programmer

Additional job roles that might be interested:

• Infrastructure architect
• Network designer

There are no formal prerequisites for Cisco Certified DevNet Associate certification, but you should make sure to have a good understanding of the exam topics before taking the exam. And before taking this course, you should have:
• Basic computer literacy
• Basic PC operating system navigation skills
• Basic Internet usage skills
• Hands-on experience with a programming language (specifically Python)
