Pure Storage FAAA_004 Exam Questions

The customer has a cloud-first strategy and does not wish to own additional capital assets, meaning they are looking for a solution that operates entirely within the public cloud without requiring on-premises hardware. Additionally, their primary goal is to reduce cloud storage costs while managing a large volume of database data (100 TB).

Cloud Block Store (CBS) is the ideal solution for this requirement. CBS is a software-defined block storage solution that runs natively in the public cloud (e.g., AWS or Azure). It provides enterprise-grade storage features like deduplication, compression, and thin provisioning, which help optimize storage usage and reduce costs. By leveraging CBS, the customer can efficiently manage their database workloads in the cloud while minimizing storage expenses.

Why Not the Other Options?

A . Evergreen//Flex: This is a subscription-based model for on-premises FlashArray hardware. Since the customer does not want to own any additional capital assets, this option does not align with their cloud-first strategy.

B . Evergreen//Forever: Similar to Evergreen//Flex, this is an on-premises solution that involves hardware ownership, which does not meet the customer's requirements.

D . Portworx DBaaS: While Portworx is a containerized storage solution for databases, it is primarily designed for Kubernetes environments and does not directly address the need to reduce cloud storage costs for traditional database workloads.

Key Points:

Cloud Block Store: A cloud-native block storage solution that reduces storage costs through advanced data reduction techniques.

Cloud-First Strategy: CBS aligns perfectly with the customer's desire to avoid capital expenditures and operate entirely within the public cloud.

The DirectCompress Accelerator (DCA) is a hardware component introduced in certain FlashArray models to enhance inline data compression performance. To determine the minimally required FlashArray model that includes DCA, let's analyze the options:

Analysis of Options:

A . FlashArray//X70 R4 :

The FlashArray//X70 R4 was the first model to include the DirectCompress Accelerator (DCA).

This makes it the minimally required model for DCA support.

B . FlashArray//X70 R3 :

The FlashArray//X70 R3 does not include the DCA. It relies on software-based compression, which is less efficient than hardware-accelerated compression.

C . FlashArray//X90 R4 :

The FlashArray//X90 R4 includes DCA but is a higher-tier model than the X70 R4. While it supports DCA, it is not the minimal requirement.

D . FlashArray//XL130 :

The FlashArray//XL130 is a high-performance model that includes DCA, but it is overkill for this requirement and not the minimal model.

Recommendation:

The correct answer is A. FlashArray//X70 R4 , as it is the first model to include the DirectCompress Accelerator (DCA).

Pure Storage helps customers increase storage density in their arrays as new technology becomes available through its Evergreen//One subscription program. Here's an analysis of the options:

Analysis of Options:

A . Customers can attach third-party storage arrays to the Pure Storage array :

Pure Storage does not support attaching third-party storage arrays directly to its arrays. This is not a valid option.

B . Customers can leverage Pure Storage's Capacity Consolidation offering :

While capacity consolidation is a benefit of Pure Storage arrays, it does not specifically address increasing storage density with new technology.

C . Customers can mix HDDs and flash modules within the same array :

Pure Storage arrays are all-flash and do not support mixing HDDs and flash modules. This is not a valid option.

D . Customers can add a shelf with an Evergreen//One subscription :

With Evergreen//One , customers can non-disruptively add new shelves or upgrade their arrays to take advantage of newer, denser storage technologies without rebuying existing storage. This is the correct answer.

Recommendation:

The correct answer is D. Customers can add a shelf with an Evergreen//One subscription .
