Question 2/102/10

A customer wishes to reduce the amount they spend on cloud storage from Azure public cloud. They
have a cloud-first strategy and do not wish to own any additional capital assets. The applications data
mainly consists of 100 TB of Database data.
Which product satisfies this requirement?

Select the answer:Select the answer

1 correct answer

Evergreen//Flex

Evergreen//Forever

Cloud Block Store

Portworx DBaaS

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.

Quiz

Question 4/104/10

What architectural design simplifies controller upgrades from FlashArray//XR2 to //XR3?

Select the answer:Select the answer

1 correct answer

Common controller chassis for both models

InfiniBand connectivity between controllers

NVRAM modules in both controllers

Re-use of existing HBAs to prevent WWN changes

The architectural design that simplifies controller upgrades from FlashArray//XR2 to //XR3 is the use
of a common controller chassis for both models. This design allows customers to upgrade their
controllers without replacing the entire array chassis, minimizing downtime and complexity during
the upgrade process.
Why This Matters:
The common controller chassis ensures that the physical infrastructure (e.g., drive shelves, power
supplies, and other components) remains unchanged during the upgrade. Only the controllers
themselves need to be swapped out, which significantly reduces the time and effort required for the
upgrade.
This approach also eliminates the need for re-cabling or reconfiguring the array, as the chassis and its
connections remain consistent between the two models.
Why Not the Other Options?
B . InfiniBand connectivity between controllers: While InfiniBand is used for high-speed
communication between controllers in FlashArray systems, it is not directly related to simplifying
controller upgrades. It is a feature of the architecture but does not address the ease of upgrading
between models.
C . NVRAM modules in both controllers: NVRAM (Non-Volatile RAM) is used to ensure data integrity
during power loss, but it is not a factor in simplifying controller upgrades. Both XR2 and XR3 models
include NVRAM, so this is not unique to the upgrade process.
D . Re-use of existing HBAs to prevent WWN changes: While reusing HBAs can help avoid changes to
World Wide Names (WWNs), this is not a key factor in simplifying the upgrade process. The common
controller chassis is the primary design feature that streamlines the upgrade.
Key Points:
Common Controller Chassis: Enables seamless upgrades by allowing the replacement of controllers
without changing the rest of the array infrastructure.
Minimized Downtime: Reduces the time and complexity of upgrades, ensuring minimal disruption to
operations.
Consistency Across Models: Ensures compatibility and continuity between different generations of
FlashArray controllers.

Question 6/106/10

A customer is reviewing their disaster recovery strategy and want to replicate their data to a
secondary datacenter. They have stated that they have internal SLAs around RPO and RTO that they
are not currently meeting.
Which two FlashArray features should the SE focus on? (Choose two.)

Select multiple answer: (Choose 2)Select the answer

2 correct answers

FlashRecover

ActiveCluster

CloudSnap

ActiveDR

The customer is reviewing their disaster recovery (DR) strategy and wants to replicate data to a
secondary datacenter while addressing internal SLAs for RPO (Recovery Point Objective) and RTO
(Recovery Time Objective) . To meet these requirements, the SE should focus on two key Pure
Storage FlashArray features: FlashRecover and ActiveDR .
Why These Features?
FlashRecover:
FlashRecover is a snapshot-based replication feature that allows efficient point-in-time copies of data
to be replicated to a secondary site.
It helps achieve low RPOs by enabling frequent snapshots and replication to the DR site.
This ensures minimal data loss in the event of a failure.
ActiveDR:
ActiveDR is a disaster recovery solution that provides asynchronous replication between two
FlashArrays.
It is specifically designed to minimize RTO by enabling fast failover and failback capabilities.
ActiveDR ensures that the secondary site is always ready to take over with minimal downtime,
meeting strict RTO requirements.
Why Not the Other Options?
B . ActiveCluster:
ActiveCluster is a synchronous replication solution for high availability across two sites. While it
provides zero RPO and near-zero RTO, it requires both sites to be within synchronous distance
(typically <10ms latency). Since the customer is replicating to a secondary datacenter (likely farther
away), ActiveCluster is not suitable.
C . CloudSnap:
CloudSnap is a feature that ofloads snapshots to cloud storage (e.g., AWS S3 or Azure Blob). While it
is useful for backup and archival purposes, it does not provide the real-time replication and failover
capabilities needed for DR with strict RPO and RTO SLAs.
Key Points:
FlashRecover: Enables efficient replication with low RPOs through snapshot-based replication.
ActiveDR: Provides asynchronous replication with fast failover and failback capabilities to meet RTO
requirements.
SLA Alignment: Both features are designed to help customers meet their internal SLAs for RPO and
RTO.

Question 7/107/10

Refer to the exhibit.

Certification Exam Pure Storage FlashArray Architect Associate Pure Storage Pure-Storage-FAAA_004 4-2001688122

A customer is experiencing latency in the VMware environment connected to this array. What should
the SE recommend?

Select the answer:Select the answer

1 correct answer

Add DirectFlash Modules as the system is disk bound

Upgrade the controllers

Add network cards to alleviate network congestion

Check the ESXi host

The exhibit shows latency in the VMware environment connected to the FlashArray. When
troubleshooting latency issues in a VMware environment, the first step is to identify whether the
issue originates from the storage array, the network, or the ESXi host. In this case, the SE should
recommend checking the ESXi host , as it is often the source of latency problems in VMware
environments.
Why This Matters:
ESXi Host Issues:
The ESXi host could be experiencing resource contention (e.g., CPU, memory, or network
bottlenecks) or misconfigurations (e.g., improper queue depth settings or multipathing policies).
High latency on the ESXi host can impact the performance of virtual machines and appear as storage
latency, even if the FlashArray itself is functioning optimally.
Why Not the Other Options?
A . Add DirectFlash Modules as the system is disk bound:
Pure Storage FlashArray uses DirectFlash Modules, which are NVMe-based and provide extremely
low latency. If the array were disk-bound, it would indicate a hardware limitation, but this is unlikely
with FlashArray's architecture. The issue is more likely related to the ESXi host or network.
B . Upgrade the controllers:
Controller upgrades are typically unnecessary unless the array is nearing its performance limits.
Since the exhibit does not indicate any signs of controller saturation, this is not the correct
recommendation.
C . Add network cards to alleviate network congestion:
While network congestion can cause latency, the issue is more likely related to the ESXi host
configuration. Adding network cards should only be considered after confirming network bottlenecks
through diagnostics.
Key Points:
ESXi Host Diagnostics: Start by checking the ESXi host for resource contention, misconfigurations, or
improper settings.
Storage Array Health: Verify that the FlashArray is not experiencing any performance issues (e.g.,
high queue depths or latency).
Network Analysis: Only after ruling out the ESXi host and storage array should network-related issues
be investigated.
