As the Cloud Architect for your company, you have been tasked with designing a high performance (HPC) cluster in Oracle Cloud Infrastructure (OCI). The following requirements have been defined:
* The cluster must be a minimum of three nodes, but may increase to six nodes when demand requires.
* The cluster must be resilient to any potential infrastructure failures.
* To minimize latency, all nodes must be deployed within the same availability domain (AD).
* Adding or replacing nodes within the cluster should take no more than 30 minutes.
Which two steps should be performed to satisfy these requirements in OCI? (Choose two.)
