True or false: Red Hat OpenStack Services on OpenShift enables management of applications running on OpenShift Virtualization VMs using OpenStack APIs.
-
True
Incorrect: Red Hat OpenStack Services on OpenShift does not need nor integrates with OpenShift Virtualization. -
False
Correct: Red Hat OpenStack Services on OpenShift manages application VMs directly, without using OpenShift Virtualization. It uses the VM manager included with RHEL (libvirt).
-
-
True or False: An OpenStack Operator needs access to the OpenShift web console to manage application workloads running as VMs on their OpenStack clusters.
-
True
Incorrect: OpenStack Operators do not require access to any OpenShift tool to perform their daily work. -
False
Correct: OpenStack Operators only need access to OpenStack APIs, which they get from the OpenStack client and the OpenStack Horizon dashboard.
-
-
True of False: An OpenStack Operator needs access to RHEL compute nodes to manage application VMs running on those nodes.
-
True
Incorrect: OpenStack Operators should not perform any tasks directly on compute nodes. -
False
Correct: OpenStack Operators manage application VMs using OpenStack APIs.
-
-
True or False: An OpenStack Administrator needs direct access to the OpenShift clusters running the OpenStack control planes of their OpenStack clusters.
-
True
Correct: OpenStack Administrators are required to manage OpenStack services using Kubernetes APIs and custom resources, and that requires access to OpenShift clusters. -
False
Incorrect: OpenStack Administrators cannot manage OpenStack services without access and visibility of their containers running on OpenShift.
-
-
True or False: An OpenStack Operator uses the Horizon dashboard for all daily tasks.
-
True
Incorrect: OpenStack Operators can perform most, but not all, of their tasks using the Horizon web UI. -
False
Correct: Sometimes an OpenStack operator needs to use the OpenStack client or some other tool which provides access to OpenStack APIs not available through Horizon.
-
-
An OpenStack Operator focuses on OpenStack API resources that affect individual application workloads, as opposed to OpenStack API resources which affect an entire cluster.
-
True
Correct: OpenStack Operators role focus on applications and their associated VMs, virtual networks, and virtual storage. -
False
Incorrect: Dealing with OpenStack API resources which potentially affect an entire cluster is the job of OpenStack Administrators.
