A developer creates an application for a Cisco Catalyst 9000 switch in a Docker container. Which action must be taken to host the application on the switch?
A.
Export the application as a TAR file and import the file to the switch.
B.
Connect the switch to Cisco DNA Center and push the application through the platform.
C.
Use the Cisco IOxClient tool to export the application to a ZIP file and push the file to the switch.
D.
Copy the application code to a NETCONF file and upload the file to the switch.
given answer is correct.
Once developers have built the docker application, running the standard “docker save” command can be used to export the application as “.tar” compressed file. The application can then be deployed on the Catalyst 9000 series switches. Cisco’s ioxclient tool is no longer required to package the application. Ioxclient is an optional tool for developers who want to define additional parameters for the application.
Steps are:
1. Design, develop, and dockerize the application.
2. Upload the containerized application to a repository, save the container as a .tar file, and prepare and format the USB drive.
3. Download the application to usbflash1 and configure the relevant VLAN interface on the switch.
4. Install the application on the switch via the CLI
5. Configure the application that hosts vNIC on the switch.
6. Activate and start the hosted application via the CLI
Yes its A

From Official Cert Guide "You now have several deployment options. You can use:
Cisco DNA Center, Cisco IOx Local Manager, or you can do CLI-based actions."
A could assume CLI, B is correct, C is IOx LM, no client tool
Correct answer is A:
Create docker and import to a tar file:
