Pure Storage FAAA_004 Exam Dumps

Pure Storage's Right-Size Guarantee protects the customer for 12 months starting from the date of arrival . This guarantee ensures that if the customer's storage needs grow beyond their initial purchase, they can upgrade to larger capacity shelves or arrays without overpaying for the additional capacity.

Why This Matters:

The 12-month protection period gives customers ample time to assess their storage requirements and make adjustments as needed. This flexibility is particularly valuable for organizations with dynamic or unpredictable growth patterns.

By protecting the customer for a full year, Pure Storage ensures that they can scale their storage infrastructure efficiently without incurring unnecessary costs.

Why Not the Other Options?

A . 30 days starting from the date of arrival:

A 30-day protection period would be insufficient for most customers to evaluate their storage needs and make informed decisions about upgrades.

B . 6 months starting from the date of arrival:

While 6 months is longer than 30 days, it is still shorter than the standard 12-month protection period offered by Pure Storage.

D . Until the Evergreen subscription expires:

The Right-Size Guarantee is not tied to the duration of the Evergreen subscription. It is specifically valid for 12 months from the date of arrival.

Key Points:

12-Month Protection: Provides customers with a full year to assess their storage needs and leverage the Right-Size Guarantee.

Scalability: Ensures customers can upgrade their storage infrastructure cost-effectively as their needs evolve.

Customer-Centric Approach: Reflects Pure Storage's commitment to delivering flexible and future-proof solutions.

Exhibit controllers of a Pure Storage FlashArray , specifically labeled as CT1 (top) and CT2 (bottom). This labeling is consistent with Pure Storage's naming convention for its controllers.

Why This Matters:

Controller Identification:

Pure Storage FlashArray controllers are typically labeled as CT1 and CT2 to distinguish between the two controllers in an active/active architecture.

Both controllers work together to provide high availability and redundancy, ensuring seamless operation even if one controller is offline for maintenance or upgrades.

Active/Active Architecture:

In an active/active design, both controllers share the workload equally. If one controller is taken offline, the other seamlessly handles all I/O operations without impacting performance or availability.

Why Not the Other Options?

B . Top: Primary, Bottom: Secondary:

Pure Storage does not use 'Primary' and 'Secondary' labels for its controllers. Instead, it uses specific identifiers like CT1 and CT2 to refer to the controllers.

C . Top: CTO, Bottom: CT1:

The label 'CTO' is not a valid designation for FlashArray controllers. Pure Storage consistently uses CT1 and CT2 to identify the controllers.

Key Points:

Controller Labels: Pure Storage FlashArray controllers are labeled as CT1 and CT2.

Active/Active Design: Both controllers operate simultaneously to ensure high availability and performance.

Redundancy: The dual-controller architecture provides fault tolerance and minimizes downtime during maintenance or failures.

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).

When setting up replication on a Pure Storage FlashArray, an admin creates a Protection Group to define which entities will be replicated to a remote FlashArray. When adding members to a Protection Group, there are three valid choices: Volumes , Snapshots , and Host Groups . Here's a breakdown of each option:

Choices for Adding Members:

Add Volumes :

Volumes are the primary entities that can be added to a Protection Group. Replication ensures that the data within these volumes is copied to the remote FlashArray.

This is the most common use case for replication, especially for protecting critical data such as databases or virtual machine disks.

Add Snapshots :

Snapshots of volumes can also be added to a Protection Group. This allows point-in-time copies of the data to be replicated to the remote array.

Snapshots are useful for disaster recovery scenarios where you need to restore data to a specific point in time.

Add Host Groups :

Host Groups can be added to a Protection Group to replicate all volumes associated with the host group. This simplifies management when multiple volumes are tied to a single application or server.

Replicating Host Groups ensures that all related volumes are protected together, maintaining consistency across the workload.

Incorrect Options:

A . Add Hosts :

Hosts themselves cannot be directly added to a Protection Group. Instead, replication focuses on the data (volumes) or logical groupings (host groups) associated with the hosts.

E . Add HBA WWN :

HBA WWNs (World Wide Names) are identifiers for Fibre Channel adapters and are not relevant to replication or Protection Groups. They are used for zoning and connectivity but do not play a role in defining replication members.

Final Recommendation:

The correct options are B. Add Volumes , C. Add Snapshots , and D. Add Host Groups , as these are the valid entities that can be added to a Protection Group for replication.

Purity CloudSnap is a feature of Pure Storage FlashArray that enables customers to offload snapshots to public cloud storage for long-term retention or disaster recovery purposes. To determine which public cloud storage services are supported as offload targets, let's analyze the options:

Analysis of Options:

A . Amazon AWS S3 :

Amazon S3 (Simple Storage Service) is one of the most widely used object storage services in the public cloud.

Purity CloudSnap supports AWS S3 as an offload target, making it a valid choice.

B . IBM Object Storage :

IBM Object Storage is not currently supported as an offload target for Purity CloudSnap.

Pure Storage focuses on integration with major cloud providers like AWS and Azure.

C . Amazon AWS EBS :

Amazon EBS (Elastic Block Store) is a block storage service designed for use with EC2 instances.

However, CloudSnap does not support AWS EBS as an offload target because it is intended for object storage services like S3.

D . Azure Blob Storage :

Azure Blob Storage is Microsoft's object storage service, similar to AWS S3.

Purity CloudSnap supports Azure Blob Storage as an offload target, making it a valid choice.

Recommendation:

The correct answers are A. Amazon AWS S3 and D. Azure Blob Storage , as these are the supported public cloud storage services for CloudSnap.
