What does Pure Storage's Right-Size Guarantee promise?
答案:D
問題 #45
A company has two data centers that are 30 miles apart with a round trip latency of 4ms.
What Pure Storage software will allow the lowest RPO disaster recovery strategy between the two data centers?
答案:B
解題說明:
To achieve the lowest RPO (Recovery Point Objective) disaster recovery strategy between two data centers located 30 miles apart with a round-trip latency of 4ms, Purity Snapshot Replication is the best choice. Here's why:
Analysis of Options:
A . Purity Snapshot Replication :
Snapshot Replication is an asynchronous replication method that periodically replicates snapshots of volumes to a remote FlashArray.
With a round-trip latency of 4ms, Snapshot Replication can achieve very low RPOs (typically seconds to minutes), making it suitable for disaster recovery in this scenario.
B . Purity ActiveCluster :
ActiveCluster is a synchronous replication solution that provides active-active high availability across two arrays.
While ActiveCluster offers zero RPO and zero RTO, it is typically limited to shorter distances due to latency constraints. At 30 miles and 4ms latency, ActiveCluster may still work but is less optimal compared to Snapshot Replication for disaster recovery.
C . Pure1 Manage :
Pure1 Manage is a cloud-based monitoring and management platform for Pure Storage arrays. It does not provide replication or disaster recovery capabilities.
D . Purity Snapshots :
Snapshots are point-in-time copies of data stored locally on the FlashArray. They do not provide replication to a remote site and are therefore unsuitable for disaster recovery.
Recommendation:
The correct answer is A. Purity Snapshot Replication , as it provides the lowest RPO for disaster recovery over a 30-mile distance with 4ms latency.

問題 #46
A healthcare customer who is already leveraging a FlashArray//X50 for VMware datastores has added a radiology department to their facility and requires a file-based storage solution for medical imaging.
* They have 35 usable TB free.
* They anticipate storing 15 TB in images.
* System load is currently 35%.
Which approach will enable this workload?
答案:D
解題說明:
The healthcare customer already has a FlashArray//X50 with 35 usable TB free and anticipates storing 15 TB of medical imaging data . Since the system load is currently 35% , they can enable FA File on the array as-is to support the new workload.
Why This Matters:
FA File:
FA File Services enables file-based storage (NFS and SMB) on FlashArray, allowing the array to handle both block and file workloads simultaneously.
With 35 TB of free capacity and only 15 TB required for medical imaging, there is sufficient space to accommodate the new workload.
The current system load of 35% indicates that the array has ample headroom to handle the additional workload without requiring upgrades.
Why Not the Other Options?
A . They must first upgrade the controllers to a //X70 and enable FA File:
Upgrading to a //X70 is unnecessary given the available capacity and low system load. The current //X50 is capable of supporting the workload.
C . Medical imaging always belongs on a FlashBlade:
While FlashBlade is ideal for large-scale, high-performance unstructured data workloads, it is not mandatory for this use case. FA File on FlashArray//X50 is sufficient for 15 TB of medical imaging data.
D . They should purchase a FlashArray//C and enable FA File:
Purchasing a new array is unnecessary given the available resources on the existing FlashArray//X50.
Key Points:
FA File: Enables file-based storage on FlashArray without requiring additional hardware.
Capacity and Load: The array has sufficient free space and performance headroom to handle the new workload.
Cost Efficiency: Avoids unnecessary upgrades or purchases, optimizing costs while meeting requirements.

問題 #47
A customer is unsatisfied because the level of data reduction on their FlashArray is NOT as high as expected. What two statements should the SE make to the customer? (Choose two.)
答案:A,C
解題說明:
If a customer is unsatisfied with the level of data reduction on their FlashArray, the SE should make the following two statements:
FlashArray's deduplication effectiveness will usually increase as the data quantity grows:
Deduplication relies on identifying and eliminating duplicate data blocks. As more data is written to the array, the likelihood of finding duplicates increases, improving the overall deduplication ratio.
Customers should expect better data reduction results over time as their dataset grows.
The Right-Size Guarantee means that the customer can work with their SE if necessary:
Pure Storage's Right-Size Guarantee ensures that customers receive the expected effective capacity based on their workload's data reduction profile. If the actual data reduction does not meet expectations, the customer can collaborate with their SE to address the issue and potentially adjust their subscription or configuration.
Why Not the Other Options?
A . A FlashArray's compression and deduplication will need to be tuned for data subsets:
FlashArray's data reduction techniques (compression and deduplication) are automatic and do not require manual tuning. This statement is misleading.
C . FlashArray data reduction needs to be tuned to increase its effectiveness:
Similar to Option A, FlashArray's data reduction mechanisms are fully automated and do not require manual intervention.
Key Points:
Data Growth: Deduplication effectiveness improves as more data is written to the array.
Right-Size Guarantee: Provides assurance that customers can work with their SE to address data reduction concerns.
Automatic Optimization: FlashArray's data reduction features are self-optimizing and do not require manual tuning.

問題 #48
A customer currently has a FlashArray//X for their block storage with 40 TB of available storage. They need 10 TB of file workloads and want to spend the least amount possible on infrastructure.
What should the SE recommend?
答案:B
解題說明:
The customer currently has a FlashArray//X with 40 TB of available block storage and needs to add 10 TB of file workloads while minimizing infrastructure costs. Let's analyze the options:
Analysis of Options:
A . Run both workloads on the current FlashArray :
Pure Storage FlashArray supports both block and file workloads using the Purity File Services feature, which allows customers to run file workloads directly on their FlashArray.
Since the FlashArray already has 40 TB of available storage, adding 10 TB of file workloads is feasible without requiring additional hardware. This is the most cost-effective solution.
B . Add another disk pool for file storage to their current FlashArray :
Adding a separate disk pool for file storage is unnecessary because Purity File Services can handle both block and file workloads on the same array.
C . Purchase an entry-level FlashBlade for the file workload :
While FlashBlade is designed for file and object workloads, purchasing a new FlashBlade would be significantly more expensive than leveraging the existing FlashArray. This option does not align with the customer's goal of minimizing costs.
D . NDU the FlashArray //X to a //XL and run both workloads there :
Upgrading the FlashArray//X to a FlashArray//XL via a Non-Disruptive Upgrade (NDU) is unnecessary for this use case. The current FlashArray//X has sufficient capacity to handle both workloads, and upgrading to a higher-tier array would increase costs unnecessarily.
Recommendation:
The most cost-effective solution is A. Run both workloads on the current FlashArray , leveraging Purity File Services to support the file workload.

Highlights the versatility of FlashArray for both block and file workloads.
