- A. 4
- B. 3
- C. 7
- D. 6
Answer : C
Question 6

Which data protection feature enables this capability?
- A. DRT clones
- B. Snapshot using type protocol
- C. Instant access session
- D. Snapshot using type .snapshot
Answer : D
Question 7
An Architect is designing a Dell PowerStore solution for two workload groups:
A mission-critical database requiring minimal data loss
File services requiring quick local recovery from user errors
Which recommendation supports each operational need?
- A. Synchronous replication for the database and snapshots for file services
- B. Synchronous replication for file services and snapshots for audit retention
- C. Snapshots for the database and synchronous replication for audit retention
Answer : A
Question 8
A customer is gathering workload information for sizing a new PowerStore. They are concerned they will be unable to provide an accurate data reduction ratio for each workload because the current legacy storage array does not perform any data reduction.
Why is determining the data reduction ratio (DRR) important when sizing a storage solution?
- A. A small DRR may result in configuring more drives than necessary.
- B. A small DRR may result in configuring fewer drives than necessary.
- C. DRR impacts raw capacity.
- D. DRR impacts useable capacity.
Answer : A
Question 9
A company requires a high-availability storage platform with no single point of failure.
Which design feature of PowerStore supports this requirement?
- A. End-to-end NVMe
- B. Dual active controllers
- C. NVRAM write cache
- D. Scale-out architecture
Answer : B
Question 10
A storage team is implementing user roles to restrict access to certain functions within PowerStore Manager.
Which role is most appropriate to allow the user to perform day-to-day storage activity and prevent user account modification?
- A. Storage Administrator
- B. Device Management
- C. Administrator
- D. Operator
Answer : A
Question 11
A company running VMware workloads needs high-throughput, low-latency storage access.
Which protocol would the architect recommend when integrating with PowerStore?
- A. NFS
- B. FCoE
- C. NVMe/TCP
- D. iSCSI
Answer : C
Question 12
A customer plans to consolidate an aging VMware infrastructure onto a new Dell PowerStore system. During the design assessment, the Solutions Architect identifies these key constraints:
All existing workloads run as VMware virtual machines stored on external SAN-based datastores.
The customer requires a non-disruptive migration path that preserves VM configuration and minimizes downtime during cutover.
The current environment uses a mix of VMFS versions, some of which are no longer recommended for direct host-based copy tools.
The PowerStore deployment model supports VMware integration features that influence datastore placement and migration methods.
The Solutions Architect must determine which supported migration mechanism best aligns with VMware-to-PowerStore workload movement.
Which method should the Architect recommend?
- A. Native PowerStore import workflows
- B. RecoverPoint for VMs replication
- C. Windows SMB file copy utilities
- D. Host-based LVM migration tools
Answer : A
Question 13
A Storage Architect is planning a new Dell PowerStore design to support a mission critical database environment that currently runs on a local storage. Before selecting the correct array model and sizing the solution, the Architect must fully understand the database’s I/O profile, workload variability, and peak performance characteristics.
Which action should the Architect perform?
- A. Collect workload metrics using RVTools.
- B. Collect workload metrics using LiveOptics.
- C. Collect workload metrics using Dell AIOps.
Answer : B
Question 14
A Storage Architect is designing an appliance addition to an existing single appliance PowerStore cluster. The upgrade requires that the system bonds be connected to the network. The customer has connected the networks and sent the following diagram:
What would be the impact on the system bond with the above configuration?
- A. It connects as active/degraded.
- B. It connects as active/active.
- C. It connects as active/passive.
Answer : C
Question 15
A customer has a single PowerStore 5200T appliance running mixed block workloads over iSCSI. After a new analytics application is deployed, performance testing shows that the existing appliance cannot meet the new IOPS and latency requirements, even though there is still free capacity available.
Which design approach is most appropriate to meet the new performance requirement while minimizing configuration changes?
- A. Considering changing the front-end protocol to something more performant like Fibre Channel.
- B. Add an additional appliance to the cluster and redistribute performance-sensitive workloads across the appliances.
- C. Add at least two additional NVRAM drives, thereby increasing the amount of cache in the existing appliance.
- D. Add additional NVMe drives to the existing appliance and redistribute performance-sensitive workloads across storage pools.
Answer : B
