Demo Questions

Question 1
A customer with several HPE 3PAR StoreServ arrays has reported latencies with newly updated applications.
You have proposed changes to the AO configuration and need to provide high-resolution reports on how the change has affected the latencies.
What should you propose on delivering the service time and I/O workload information daily for you and the customer?
  1. Use IMC to schedule performance data gathering and email delivery.
  2. Schedule SSMC System Reporter to send the defined email reports.
  3. Enable the Service Processor to gather Performance data and schedule data transfer.
  4. Login to InfoSight and analyze Advanced Performance history.
Correct answer: B
Explanation:
The HPE 3PAR SSMC (StoreServ Management Console) System Reporter is the tool that should be used to generate and schedule high-resolution performance reports, including service time and I/O workload information. By configuring System Reporter to send daily email reports, both you and the customer can monitor the impact of changes made to the Adaptive Optimization (AO) configuration. This ensures that any latency issues or performance improvements are documented and can be analyzed regularly.HPE 3PAR SSMC System ReporterHPE Performance Monitoring Tools

Question 2
A customer is implementing a new high performance database environment.
What type of storage should you recommend?
  1. scale-out storage
  2. object store
  3. system-defined storage
  4. network-attached storage
Correct answer: A
Explanation:
For a high-performance database environment, scale-out storage (Option A) is the recommended solution. Scale-out storage architectures allow for the expansion of storage capacity and performance by adding more nodes to the storage cluster. This approach provides linear scalability, enabling the environment to grow as the database's demands increase. It is particularly effective for high-performance workloads because it balances the load across multiple nodes, reducing bottlenecks and ensuring consistent performance.Scale-out storage also supports high availability and resilience, which are critical for maintaining uptime and reliability in database environments that require rapid data access and processing.HPE Scale-Out Storage SolutionsHPE Storage Overview==================

Which technology should you recommend?
  1. DRAM
  2. SRAM
  3. NVMe SCM
  4. NAND SSD
Correct answer: C
Explanation:
For the customer requiring a caching tier that offers extremely low-latency and persistent storage, NVMe Storage Class Memory (SCM) (Option C) is the ideal technology. NVMe SCM provides the performance characteristics of DRAM with the persistence of traditional storage, making it suitable for caching applications where ultra-low latency is crucial. NVMe SCM also supports capacities exceeding 500GB, which aligns with the customer's requirement.This technology is particularly advantageous in environments where quick access to data is critical, such as in financial services or real-time analytics applications. It bridges the gap between volatile DRAM and slower NAND SSDs, providing a highly responsive and durable storage solution.HPE NVMe Storage SolutionsHPE Storage Class Memory

Question 4
A customer is implementing an SAP HANA environment and is looking for an alternative to an entirely in-memory database.
Which storage technology should you recommend?
  1. SAS SSD
  2. NVMe SSD
  3. NVMe SCM
  4. Intel Optane
Correct answer: C
Explanation:
In an SAP HANA environment, the speed and latency of storage are critical for performance, especially when dealing with large datasets. While SAP HANA is designed to run entirely in memory, some customers may seek alternatives that offer a balance between performance and cost.NVMe SCM (Storage Class Memory) is a cutting-edge storage technology that offers extremely low latency and high performance, making it an ideal alternative for environments like SAP HANA. NVMe SCM provides faster data access speeds than traditional SSDs and even NVMe SSDs, making it a perfect fit for workloads that demand high-speed data processing, such as SAP HANA.HPE Storage for SAP HANAHPE NVMe Storage Solutions

Question 6
Which tool is used to determine current compaction ratios on Primera arrays?
  1. WebUI
  2. Storage Management Utility (SMU)
  3. NinjaStars
  4. SSMC System Reporter
Correct answer: C
Explanation:
When managing HPE Primera arrays, it's important to assess the current compaction ratios to understand how effectively data is being stored.NinjaStars is an HPE tool specifically designed to analyze and report on data reduction technologies, including deduplication and compression, on HPE storage arrays like Primera. It helps in determining the compaction ratios, providing insights into how efficiently the storage capacity is being utilized.HPE Primera StorageHPE NinjaTools Suite

Question 7
A customer wants to make a full copy replica of a database to use for performance testing.
Which technology should they use to create the copy?
  1. deduplication
  2. snapshot
  3. clone
  4. synthetic full
Correct answer: C
Explanation:
When a customer needs to create a full copy replica of a database for performance testing, the best technology to use is a clone. A clone creates an exact, independent copy of a volume, which can be used separately from the original. This is particularly useful for scenarios such as testing, development, or backup, where an exact copy of the data is required without affecting the production environment.HPE 3PAR and Primera Clone TechnologyHPE Data Protection and Replication

Question 8
You are advising a customer on a new backup strategy to deploy HPE StoreOnce.
What should you recommend to ensure the best storage utilization and performance?
  1. consolidate activity windows for housekeeping tasks
  2. size solution for a single backup device
  3. combine management and backup Ethernet traffic
  4. use separate backup targets for different data types
Correct answer: D
Explanation:
When deploying HPE StoreOnce, it is essential to use separate backup targets for different data types to ensure optimal storage utilization and performance. Different data types may have varying deduplication ratios, backup windows, and recovery requirements. By segregating these data types into separate backup targets, the system can more efficiently manage deduplication, compression, and storage allocation, leading to better performance and reduced storage costs.HPE StoreOnce Best PracticesHPE Backup Solutions

Question 9
Refer to the exhibit.
You are designing a new Primera solution and demonstrating performance numbers to the customer. The customer reviews the configuration and requests a change to the configuration that will increase Random Write IOPS.
Which action will satisfy the customer request?
  1. Add more disks of smaller capacity
  2. Upgrade the HPE Primera base model
  3. Change to larger SSDs
  4. Add more FC Ports
Correct answer: A
Explanation:
In the scenario presented, the customer requests an increase in Random Write IOPS for their HPE Primera solution. To achieve this, adding more disks of smaller capacity is the most effective approach (Option A). By increasing the number of disks, the storage system can distribute the write operations across more disks, thereby reducing the write latency and improving the overall Random Write IOPS performance. Smaller capacity disks typically allow for better IOPS performance per GB due to their higher spindle speed and lower data density, which reduces seek times.This strategy also aligns with best practices in storage design, where increasing the number of spindles (disks) generally enhances the performance of random workloads, particularly in write-intensive environments.HPE Primera OverviewHPE Storage Products OverviewHPE Flash and Hybrid Storage Solutions
