The correct answer is D. HPE Primera Peer Persistence and Active Peer Persistence designs use HPE Quorum Witness to support automatic failover decisions between arrays. The Quorum Witness is deployed as a virtual appliance, typically from an OVA image, and is placed in a third failure domain so that it can arbitrate between the two storage systems during communication or site-failure scenarios.
HPE identifies Quorum Witness as a necessary component for automatic failover between arrays in Peer Persistence and Active Peer Persistence configurations. Option A is incorrect because Nimble
/Alletra 6000 Peer Persistence does not make the protected volume independently active through the target array in the same active-active manner. Option B is incorrect because "Active Peer Persistence" is associated with Primera/Alletra 9000/B10000-class designs, not classic Nimble terminology. Option C mixes terms: Nimble uses a Witness service for ASO behavior, but "Quorum Witness via OVA" is the precise Primera-style statement.

The correct answer is A. Existing HPE SimpliVity environments can be brought into the HPE GreenLake / Private Cloud Business Edition management experience by deploying the Data Services Connector virtual machine and importing the system into Data Services Cloud Console. HPE documentation states that Data Services Connectors are VMs that enable management of Private Cloud Business Edition with HPE Alletra Storage MP B10000 and HPE SimpliVity, and HPE guidance for existing SimpliVity customers describes downloading the connector VM, registering it, and importing SimpliVity systems. Option B is too vague and does not identify the required technical onboarding component. Option C confuses compute fleet lifecycle onboarding with PCBE/SimpliVity service integration; iLO activation through Compute Ops Management does not import a SimpliVity cluster into DSCC as a PCBE resource. Option D is legacy/analytics-oriented and does not provide the PCBE feature integration requested.

The correct answer is C. The exhibit shows an HPE Alletra Storage MP B10000 configuration based on QLC flash, with raw capacity below the customer's 450 TB target. The correct capacity adjustment is to increase the number of QLC drives in the system while selecting the sparing policy that maximizes available usable capacity for the intended design. Replacing QLC with TLC is not the right direction for a high-capacity all-flash requirement because QLC media is positioned for dense, cost-efficient capacity expansion. Adding host bus adapters does not increase raw storage capacity, so option A is unrelated to the requirement. Replacing controller nodes is also unnecessary because the problem is media capacity, not controller performance. HPE Alletra Storage MP B10000 QuickSpecs identify scale-out capacity characteristics, including maximum raw capacity per shelf, confirming that the platform is intended to scale capacity through shelves and drive population rather than by changing host-connectivity cards. The correct plan is to add QLC capacity to reach the raw-capacity target and adjust sparing appropriately. Reference/topics: B10000 capacity planning, QLC all-flash sizing, sparing policy, GreenLake proposal validation.

The correct answer is C because adding additional expansion chassis changes the physical hardware boundary of the HPE Superdome Flex complex and the resources assigned to the existing nPartition.
Such a change cannot be treated like a live virtual-machine operation or a simple online software adjustment. The existing nPartition must be powered off before the physical expansion and partition- resource changes can be completed safely and consistently. Option A is incorrect because HPE OneView management does not require removing the nPartition from management merely to perform a hardware expansion; HPE OneView supports management of Superdome Flex-class infrastructure.
Option B is incorrect because adding expansion chassis does not require replacing an expansion chassis with another base chassis for I/O redundancy in the way stated. Option D is also insufficient because placing the partition into a maintenance mode from the Rack Management Controller CLI is not equivalent to powering off the partition for a chassis-level expansion. The course includes Superdome Flex and scale-up compute designs for database and mission-critical workloads, so this question validates correct lifecycle planning for large HPE scale-up systems.

The correct answer is C because Pensando Distributed Services Platform / Distributed Services Cards are positioned for supported HPE server platforms such as HPE ProLiant, Edgeline, and Apollo systems. The purpose is to provide distributed infrastructure services, including telemetry, policy enforcement, segmentation, and security functions close to the workload rather than forcing all traffic through centralized appliances. Option A is too broad because not all Aruba switches have Pensando silicon integrated. The switch family associated with embedded Pensando data-processing capabilities is specifically the Aruba CX 10000 class, not Aruba switching in general. Option B is incorrect because the Aruba CX 6300 is an access/switching platform, not a Pensando-integrated distributed services switch. Option D is also not a valid general positioning statement for Superdome Flex in this context; the standard HPE security positioning for Pensando DSC is not based on adding per-chassis Superdome Flex licenses. The architecture principle is that HPE can extend security and telemetry into the server edge through Pensando DSC where supported by the platform.
