Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 242

A network engineer implements a Python script on a Cisco Nexus 9000 Series Switch with redundant supervisors. The script is located on a built-in container that runs as part of the Cisco NX-OS system. The requirement is to automate the periodic transfer of the Python script to a redundant supervisor. In addition, the script must be transferred to an external server using encryption and authentication. Which configuration set meets these requirements?

Answer options

• A. Enable the checkpoint feature. Configure an EEM job to transfer the script to the SCP server.
• B. Implement the guest shell synchronization feature. Configure a scheduler job to transfer the script to the TFTP server.
• C. Enable the checkpoint feature. Configure a scheduler job to transfer the script to the HTTP server.
• D. Implement the guest shell synchronization feature. Configure a CRON job to transfer the script to the SCP server.

Correct answer: D

Explanation

The correct answer is D because the guest shell synchronization feature allows for the synchronization of scripts between supervisors, and using a CRON job facilitates the periodic transfer of the script to the SCP server with the necessary security measures. Options A and C incorrectly use the checkpoint feature, which does not address the requirement for periodic scripting transfer, while option B uses TFTP, which lacks the encryption and authentication needed.
