Question # 9

An interface on a router as a Layer 3 link has been configured to another device by updating an Ansible playbook that is executed via a CI/CD pipeline. The Ansible playbook was written to push the configuration change using the ios_config module. Which automated test validates that the interface is functioning as it should?

Add a pipeline step that runs the playbook a second type. If it does not modify the device on the second run, then the interface is correctly configured.

Automated testing is already built in because the playbook execution is successful only after Ansible validates that it applied the change.

Add a pipeline step that captures and parses the packet flow for the interface.

Add a pipeline step that captures and parses the show ip interface output so that the operational state can be referenced.

Question # 10

When static routes are added to a router in a network using a CI/CD pipeline, an Ansible playbook is used to make these changes. Which steps must be added to the pipeline to validate that the changes have the intended effect on the traffic flow?

Add a step to run the debug ip routing command before the change, and add a step after the change to

issue the no debug ip routing command.

Add a step to capture the routing table before the change, and add a step after the change to capture it again. Calculate the difference between the two for review.

Add a step to ping a host on each of the static routes before the change, and a step after to repeat the same check. Calculate the difference between the two checks for review.

Add a step to run the same playbook again with the debug option enabled and use grep on the log output to ensure that the commands are not applied again.
