Dell Technologies D-PST-OE-23 Sample Questions:

01. Ransomware encrypted a volume at the primary site, and the encrypted blocks reached the recovery-site Dell PowerStore cluster in the latest update. The primary cluster has been isolated and cannot be used. Snapshots of the volume taken before the attack are available on the recovery cluster.
How should the administrator bring up a clean copy at the recovery site?
a) Run an unplanned failover on the recovery cluster to the latest replicated copy of the volume
b) Run a planned failover from the isolated primary cluster to a snapshot from before the attack
c) Run an unplanned failover on the recovery cluster to a snapshot from before the attack
d) Run Reprotect on the recovery cluster so that it pulls a clean copy back from the primary cluster
 
02. In PowerStoreOS 3.0, a storage administrator and a vSphere administrator set up asynchronous replication of vVol-based virtual machines between two Dell PowerStore clusters. Which two tasks are performed in PowerStore Manager?
(Choose two.)
a) Running the recovery plan that fails over the virtual machines
b) Creating the replication rule that sets the RPO
c) Assigning the VM storage policy to each virtual machine
d) Assigning a protection policy to each virtual machine
e) Adding the remote system connection between the two clusters
 
03. Volumes on a Dell Unity system are mapped to Linux hosts that run native MPIO. The Unity operating environment is supported for non-disruptive import, but no import host plug-in has been installed, and the application owner accepts a one-time outage. Which statement about using agentless import here is true?
a) It can be used only after the ImportKit is installed to repoint the application
b) It cannot be used, because agentless import is limited to sources without non-disruptive support
c) It cannot be used, because hosts running native MPIO must use non-disruptive import
d) It can be used, provided no host plug-in is installed on those hosts
 
04. On two Dell PowerStore T clusters running PowerStoreOS 3.0, an administrator reviews candidate volumes for metro volume configuration. Which two volumes can not be configured as metro volumes?
(Choose two.)
a) A volume still being imported from a Unity system
b) A volume created with thin provisioning
c) A volume whose policy includes a replication rule
d) A volume assigned the High performance policy for its database
e) A volume that backs a VMFS datastore shared by several ESXi hosts
 
05. Before a non-disruptive import, an administrator must install the import host software on a Windows host that uses native MPIO without the HIT Kit, and on a Linux host that uses native MPIO. Which statement should guide the maintenance plan?
a) Both installations need a host reboot before the wizard can add the hosts
b) Neither installation needs a host reboot or any application outage
c) The Linux plug-in needs a host reboot, and the Windows ImportKit installs without one
d) The Windows ImportKit needs a host reboot; the Linux plug-in does not
 
06. In PowerStoreOS 3.0, a vVol-based VM is replicated through a VM storage policy that uses a PowerStore replication rule. The VM no longer needs remote protection, but it must keep its local snapshot schedule, and other VMs still rely on the same rule. How should replication be stopped for this VM only?
a) Delete the replication rule in PowerStore Manager so that no storage policy can use it
b) Unassign the VM's protection policy in PowerStore Manager, keeping its snapshots
c) Unpair the storage containers on the two clusters so that the VM's vVols stop replicating
d) Assign the VM a VM storage policy that keeps the snapshot rule but has no replication rule
 
07. The replication network addresses on a partner Dell PowerStore cluster were changed during a network redesign. Afterward, the Remote Systems table on the local cluster shows a data connection problem for that remote system, and its replication sessions stop transferring.
Which action should the administrator run on the remote system entry?
a) Verify and Update, which detects the changes and reestablishes the data connections
b) Modify, which lets the partner's new replication addresses be typed in
c) Failover test, which confirms that the partner can reach the volumes
d) Reprotect, which restarts each session in the reverse direction from the partner
 
08. An application's VMs span three VMFS datastores, each on its own Dell PowerStore volume. The volumes replicate under three separate sessions, and a recovery test showed the datastores coming back at slightly different points in time. What change gives the three datastores one common recovery point?
a) Take a manual snapshot of each of the three volumes at the same moment before each update
b) Shorten the replication rule's RPO so that the three sessions finish closer together
c) Place the three volumes in one volume group and assign the replication policy to that group
d) Assign the three volumes the same protection policy so that their sessions share one rule
 
09. In the non-disruptive import wizard, an administrator reaches the step that adds the Windows hosts running the host plug-in. Which two pieces of information are supplied for each host?
(Choose two.)
a) The WWNs of the host bus adapters
b) The port the host plug-in listens on
c) The VNX2 SP management IP address
d) The host management IP address
e) The vCenter Server credentials
 
10. An administrator is creating several non-disruptive import sessions from a Dell VNX2 system and does not want to confirm each one manually when it reaches Ready For Cutover. How should the sessions be configured?
a) Choose automatic cutover while setting the import schedule
b) Start every session immediately so that each one cuts over on completion
c) Assign a protection policy whose replication rule triggers the cutover
d) Pause each session during the copy so that cutover can run unattended
