A DevOps engineer must use Python to manage a Cisco device. The device is in a highly secure DMZ environment. Only trusted Cisco Python libraries can be used. Which solution meets the requirements?

Developing an on-box Python script might lack the necessary isolation and control over library dependencies and execution environment required in a highly secure DMZ.

Using serverless technologies in a primary cloud provider does not directly address the requirement of managing a Cisco device in a DMZ and may introduce external dependencies and security concerns not aligned with a DMZ.

Developing an off-box Python script, while offering flexibility, may not inherently guarantee the exclusive use of trusted Cisco libraries or provide the same level of environmental control and security isolation as a containerized solution in a DMZ.

Developing a containerization application that uses trusted Cisco-provided libraries meets the requirements by providing a secure, isolated, and portable environment for Python scripts. Containers ensure that only approved libraries are used and can be deployed securely in a DMZ, offering better control over the execution environment compared to directly running scripts.
