Dell Technologies D-PWF-OE-01 Sample Questions:

01. An administrator wants to place one SDS into Instant Maintenance Mode. Another SDS in the same protection domain is already in a failed state, and the administrator notices a force override option when entering maintenance mode. Which two statements apply?
(Choose two)
a) Forcing it makes PowerFlex build a third copy before the SDS leaves
b) Entering normally is refused while another SDS is degraded or failed
c) The failed SDS is placed in maintenance mode automatically as well
d) Forcing it can make data unavailable while maintenance is active
 
02. One VM of the PowerFlex management platform cluster has stopped. PowerFlex Manager now shows a banner saying the system is undergoing maintenance, while the Block, Alerts and Events views are still usable. What does this indicate?
a) PowerFlex Manager is recovering from the failed node, and the banner clears when the node returns
b) The views show cached copies, and no new alerts are recorded until the VM is rebuilt
c) Someone placed the management platform into maintenance mode, which must be exited by hand
d) Storage I/O has paused until the management VM is back
 
03. An administrator adds an SSD to an SDS from Block > SDSs > Add Device. The SSD was taken from a decommissioned Linux server and still carries a partition with a file system. The command fails for that device with an error. Which two statements apply?
(Choose two)
a) Test only clears it first, because the tests write to it
b) A multipath device is accepted once takeover is set
c) Force Device Takeover adds it and erases its old data
d) PowerFlex refused it because the device is not clear
 
04. An administrator wants to delete a fault set in PowerFlex Manager. Several SDSs are still configured in it. What must happen before the fault set can be deleted?
a) The whole protection domain must be inactivated first
b) The SDSs in it have to be removed
c) Each SDS in it must enter Protected Maintenance Mode
d) Its storage pools have to be deleted beforehand
 
05. A data center team is comparing PowerFlex consumption models. Its architecture review must record which model cannot be delivered without a dedicated multi-node management cluster to host the PowerFlex management platform. For which consumption model is that dedicated management cluster mandatory?
a) PowerFlex appliance with partial network automation
b) PowerFlex software on existing servers
c) PowerFlex rack with its integrated networking
d) PowerFlex custom nodes on networks the customer runs
 
06. Restricted SDC mode is enabled on a PowerFlex system. A new application host has the SDC installed and connected, but the administrator cannot map any volume to it. What must be done first?
a) Approve that SDC on the Hosts list
b) Join it to a fault set
c) Install the SDT service onto the application host
d) Build a separate protection domain for it
 
07. A security administrator created a new user in CloudLink Center for PowerFlex Manager to use, gave it the SecAdmin access role and chose the client user type. Discovery of the CloudLink Center from the Resources page now fails. Which two statements apply?
(Choose two)
a) Change the role to a read-only one, because discovery only needs to read from the CloudLink Center
b) Discover it as a VM Manager, since CloudLink Center runs as a virtual machine
c) Keep the SecAdmin access role, which discovery requires
d) The account must use the local user type, since client users do not work for discovery
 
08. Which traffic does PowerFlex carry over the SDS-to-SDS network?
(Choose two)
a) Rebalance traffic after capacity is added
b) Rebuild traffic after a device or node failure
c) Journal shipping to a remote PowerFlex system
d) Host reads returned to SDCs
 
09. A Linux host uses the SDC to access PowerFlex volumes over two data networks. The server team asks whether they must configure the operating system's multipath driver for these volumes so that I/O survives a lost path. What should the administrator tell them?
a) Ask the MDM to assign a second path to each volume
b) Configure the OS multipath driver across both of the data networks for every volume
c) Map each volume twice so the host sees two devices
d) The SDC handles multipathing itself across its connections to the SDSs
 
10. An administrator plans to update a resource group to a new Intelligent Catalog tomorrow. Today PowerFlex Manager shows a critical alert on one storage node, and a storage pool is still rebuilding. What should the administrator do before starting the update?
a) Start the update now, since the rolling process will repair the node
b) Resolve the alert and let the rebuild finish first
c) Put the alerting node into Instant Maintenance Mode and update around it
d) Disable alert forwarding so the update is not interrupted
