EX370 is a performance-based hands-on exam (no multiple choice) on a live OpenShift cluster with ODF. The passing score is 210/300 (70%). Candidates install the ODF Operator, manage the underlying Ceph cluster (Rook), provision RBD and CephFS storage classes, configure NooBaa MCG ObjectBucketClaims, expand capacity, take VolumeSnapshots, and troubleshoot using the rook-ceph-tools pod. EX370 counts toward Red Hat Certified Architect (RHCA).

1Which OpenShift namespace is used by default to deploy OpenShift Data Foundation and host all of its operator and Ceph pods?
A.openshift-storage
B.openshift-operators
C.openshift-rook
D.rook-ceph
Explanation: ODF deploys all of its operators (odf-operator, ocs-operator, rook-ceph-operator, mcg-operator) and the resulting Ceph mon/osd/mgr/mds pods into the openshift-storage namespace. The StorageCluster CR is also created there.
2Which custom resource defines the desired state of an OpenShift Data Foundation deployment, including replicas, storage device sets, and resources?
A.StorageCluster
B.CephCluster
C.StorageSystem
D.OCSInitialization
Explanation: StorageCluster (ocs.openshift.io/v1) is the user-facing CR that drives the ODF install. It declares the storageDeviceSets, replica count, monPVCTemplate, and resource limits. The ocs-operator reconciles it into the lower-level CephCluster.
3Which operator must be installed before ODF when worker nodes have raw, locally-attached block devices that need to be presented to the StorageCluster?
A.Local Storage Operator
B.MCG Operator
C.OpenShift Virtualization Operator
D.External Mode Operator
Explanation: The Local Storage Operator (LSO) discovers raw devices on each node and creates persistent volumes from a LocalVolumeSet. ODF in internal mode then consumes those PVs as the backing storage for OSDs.
4What is the minimum number of worker nodes that should be labeled to host OSDs for a typical internal-mode ODF deployment?
A.3
B.1
C.2
D.5
Explanation: ODF internal mode defaults to a 3-replica Ceph CRUSH rule with failure domain=host, so a minimum of three OSD-capable worker nodes is required. Each OSD node typically also runs a mon for quorum.
5Which node label must be applied so the ocs-operator schedules ODF/Ceph pods on a worker node?
A.cluster.ocs.openshift.io/openshift-storage=''
B.node-role.kubernetes.io/storage=true
C.rook.io/storage=enabled
D.ocs/role=osd
Explanation: ODF tolerates and prefers nodes labeled cluster.ocs.openshift.io/openshift-storage='' (empty value). The ocs-operator and Rook use that label as a selector and a matching toleration to keep ODF pods on dedicated infra/storage nodes when desired.
6Which ODF deployment mode connects an OpenShift cluster to a pre-existing Ceph cluster running outside of OpenShift?
A.External mode
B.Internal mode
C.Hyperconverged mode
D.Edge mode
Explanation: External mode points the StorageCluster at an existing Ceph cluster (managed separately, often by Red Hat Ceph Storage). The CSI drivers and NooBaa run inside OpenShift while OSDs/mons live outside.
7After installing the ODF operator, which command shows the StorageCluster created in the openshift-storage namespace?
A.oc get storagecluster -n openshift-storage
B.oc get cephcluster --all-namespaces
C.oc describe odf-cluster
D.oc storage list
Explanation: oc get storagecluster -n openshift-storage lists the user-facing CR. The default StorageCluster name is ocs-storagecluster.
8What is the default name of the StorageCluster that ODF creates when installed via the OpenShift web console wizard?
A.ocs-storagecluster
B.odf-storagecluster
C.openshift-storagecluster
D.default-storagecluster
Explanation: The wizard creates a StorageCluster named ocs-storagecluster. The default StorageClasses (ocs-storagecluster-ceph-rbd, ocs-storagecluster-cephfs) and CephCluster (ocs-storagecluster-cephcluster) all derive their names from this prefix.
9In the StorageCluster CR, which field controls how many OSD replicas Ceph keeps for data placed in the default block pool?
A.spec.storageDeviceSets[*].replica
B.spec.replicas
C.spec.poolReplica
D.spec.osdReplicas
Explanation: Each entry in spec.storageDeviceSets has a replica field that determines how many OSD pods are created from that device set across failure domains. ODF defaults to replica: 3 to match the Ceph 3-way replication policy.
10Which type of OpenShift volume is consumed by an OSD pod when ODF is deployed via Local Storage Operator?
A.PersistentVolumeClaim backed by a localblock StorageClass
B.EmptyDir
C.HostPath volume mounted from /var/lib/rook
D.ConfigMap
Explanation: LSO publishes PVs from the raw devices, and the StorageCluster's storageDeviceSets reference a localblock-style StorageClass via dataPVCTemplate. Each OSD pod gets a dedicated PVC bound to one local device PV.

About the EX370 Exam

EX370 is the Red Hat Certified Specialist in OpenShift Data Foundation exam. It validates hands-on skills with ODF on OpenShift: installing the ODF Operator, managing the Ceph cluster (mon/osd/mgr/mds) via Rook, provisioning block storage (RBD), file storage (CephFS), and object storage (NooBaa Multicloud Object Gateway), managing PVCs, snapshots, clones, capacity expansion, and troubleshooting Ceph health.

EX370 Study Tips from Top Performers

1Build a real lab: 3+ worker nodes with raw block devices, install Local Storage Operator, then install ODF in internal mode
2Memorize the openshift-storage namespace and the names of every key CR: StorageCluster, CephCluster, CephBlockPool, CephFilesystem, CephObjectStore, NooBaa
3Practice exec'ing into the rook-ceph-tools pod and running ceph status, ceph osd tree, ceph df, ceph health detail
4Drill the two default StorageClasses by name: ocs-storagecluster-ceph-rbd (RWO block) and ocs-storagecluster-cephfs (RWX file)
5Master ObjectBucketClaim end-to-end: create the OBC, find the auto-generated Secret and ConfigMap, and use the credentials with the AWS CLI against the NooBaa S3 endpoint
6Practice VolumeSnapshotClass and VolumeSnapshot for both RBD and CephFS, including PVC restore from a snapshot
7Know how to add capacity: edit the StorageCluster spec.storageDeviceSets to grow OSDs, do not try to manually edit OSD pods
8Use must-gather (oc adm must-gather --image=registry.redhat.io/odf4/ocs-must-gather-rhel9) before opening a support case
9Recognize common Ceph alerts: CephClusterWarningState, CephMonQuorumAtRisk, CephOSDDiskNotResponding, CephClusterNearFull
10Time yourself: a 3-hour exam goes fast — practice working under pressure with no internet access

Frequently Asked Questions

What does EX370 cover?

EX370 is the Red Hat Certified Specialist in OpenShift Data Foundation exam. It tests installing the ODF Operator, managing the underlying Ceph cluster via Rook, provisioning block storage (RBD), file storage (CephFS), and object storage (NooBaa MCG), managing PVs/PVCs and storage classes, taking snapshots and clones, expanding capacity, and troubleshooting Ceph health on a live OpenShift cluster.

What is the EX370 exam format?

EX370 is performance-based: there are no multiple-choice questions. You receive a list of tasks to complete on a live OpenShift cluster with ODF deployed within roughly 3 hours. Passing requires 210 out of 300 points (70%). Each task is graded based on whether the resulting cluster state meets the specification.

How long is the EX370 exam?

EX370 is approximately a 3-hour single-session performance-based exam. Red Hat administers it at training centers, partner sites, and via individual remote exam (proctored). Time management is critical because each lab task can be verified independently.

What is the EX370 cost?

Red Hat lists the standard exam fee around $400-500 USD depending on region, with discounts often included in the Red Hat Learning Subscription. Individual exam vouchers are also available. Always confirm the current fee on the official EX370 page before scheduling.

Does EX370 require EX280?

Red Hat strongly recommends EX280 (OpenShift Administration) before attempting EX370, since you must already be comfortable installing operators, working with namespaces, and using oc on a running cluster. RHCE is also required to retain the Specialist credential, and EX370 counts toward Red Hat Certified Architect (RHCA).

How long should I study for EX370?

Plan for 80-120 hours of focused, hands-on study over 8-12 weeks. Set up a lab OpenShift cluster (3+ workers with raw disks) and install ODF. Practice every objective in the official content guide repeatedly until you can complete each task in under five minutes from memory.

Is EX370 valid for life?

No. Specialist credentials follow Red Hat's general 3-year recertification cycle and require a current RHCE to remain valid. You can re-pass EX370 or earn a higher Red Hat credential to keep it active.
