Question #11 (Topic: Exam A)
An organization is designing a new NAS environment using Dell PowerStore to support a variety of workloads. The planned use cases include:
A shared storage space for employees’ personal files
Departmental collaboration folders
Application-generated log data
High-performance transactional systems requiring low-latency access
Which workload is best suited for placement on the NFS/SMB file-based storage tier?
A shared storage space for employees’ personal files
Departmental collaboration folders
Application-generated log data
High-performance transactional systems requiring low-latency access
Which workload is best suited for placement on the NFS/SMB file-based storage tier?
A. Mission-critical OLTP databases and other high-intensity transactional workloads
B. User home directories and shared departmental or team file repositories
C. Log-structured merge (LSM)–based databases and large-scale analytical data pipelines
D. Real-time trading platforms and other ultra-low latency operational systems
Answer: B
Question #12 (Topic: Exam A)
During an external storage import planning workshop, the Solutions Designer must determine the feasibility of connecting a third-party storage array to a PowerStore system. Several critical constraints are identified during the assessment:
The source storage platform supports multiple connectivity protocols, but only one is currently active for host presentation.
Existing fabric zoning has limited available paths, and reconfiguration may impact production systems.
The customer requires a non-disruptive import workflow with predictable cutover timing.
The PowerStore deployment model restricts the types of external systems it can directly connect to.
Which connectivity detail would the Solutions Designer validate first?

C. The PowerStoreOS release level
D. The supported data-path identifiers
Answer: D
Question #13 (Topic: Exam A)
A Storage Architect is asked to verify if a customer network is valid for PowerStore Metro replication.
What is the maximum latency supported?
What is the maximum latency supported?
A. 10 ms
B. 2 ms
C. 5 ms
D. 1 ms
Answer: C
Question #14 (Topic: Exam A)
A customer plans to consolidate several application workloads onto PowerStore but only provides total capacity requirements.
To generate a realistic configuration, more detailed workload characteristics must be gathered.
Which set of additional information must be gathered?
To generate a realistic configuration, more detailed workload characteristics must be gathered.
Which set of additional information must be gathered?
A. Per-workload performance, read/write ratio, sequential vs. random I/O %, average I/O (block) size, and performance and capacity growth
B. Number and types of hypervisors, guest OSs and versions, connectivity, read/write ratio, sequential vs. random I/O %, and workload performance
C. Data reduction ratio, DRE geometry, capacity and CPU saturation levels, cluster appliance count, and average I/O (block) size
D. Number of storage administrators, change management process, maintenance window length, and preferred rack location for the array
Answer: A
Question #15 (Topic: Exam A)
A customer wants to replicate several volumes to protect an application. Any latency over 15 ms will cause the application to crash. The distance in circuit miles between the two sites is 1,000 miles.
Which replication method would the Storage Architect suggest?
Which replication method would the Storage Architect suggest?
A. Metro
B. Asynchronous
C. Synchronous
Answer: B
