A Cloud Deployment Engineer Is Modifying Versions of the Existing

A cloud deployment engineer is modifying versions of the existing template image to instantiate new VMs. The engineer accomplishes this through the cloud self-service portal. After the version is changed and a new VM is successfully started, it does not have any connectivity, and all ping tests to other VMs fail. Which of the following would be the BEST approach to solve the problem?

A) Start the console session to the VM; check network static routes; test the ping to default gateway and next hop; and reconfigure the gateway IP.
B) Delete the VM; create a new flavor; turn on network service; add the new image to the template manager; and reinstantiate the VM using this new image.
C) Delete the VM; check the IP assignment and planning; modify configuration in the deployment template; and instantiate the VM again using the new template.
D) Assign new IPs to the newly created VMs by changing and running the deployment template; and check the connectivity on the cloud self-service portal afterward.
