An administrator has just installed the OpenShift cluster as the first step of installing Cloud...

After successfully installing an OpenShift cluster, the most reliable way to confirm that the cluster is up and running is by checking the status of its nodes. This is done using the oc get nodes command.

The command oc get nodes lists all the nodes in the cluster and their current status.

If the installation is successful, the nodes should be in a "Ready" state, indicating that the cluster is functional and prepared for further configuration, including the installation of IBM Cloud Pak for Integration (CP4I).

Option A (Incorrect – which oc): This only verifies that the OpenShift CLI (oc) is installed on the local system, but it does not confirm the cluster installation.

Option B (Incorrect – Checking /.openshift_install.log): While the installation log may indicate a successful install, it does not confirm the operational status of the cluster.

Option C (Correct – oc get nodes): This command confirms that the cluster is running and provides a status check on all nodes. If the nodes are listed and marked as "Ready", it indicates that the OpenShift cluster is successfully installed.

Option D (Incorrect – OpenShift Admin Console Access): While the OpenShift Web Console can be accessed if the cluster is installed, this does not guarantee that the cluster is fully operational. The most definitive check is through the oc get nodes command.
