Questions # 11:

A customer has purchased a DirectFlash Shelf, but lacks available space in the same rack as the chassis. There is available space in a rack 6m away. What step should be taken prior to implementation?

Options:

Make space in the rack where the chassis is located.

Order 7m DirectFlash Shelf cables.

Relocate the chassis to the rack where there is space for the shelf.

Answer

Explanation

To connect a DirectFlash Shelf located 6 meters away from the chassis, longer (7-meter) cables should be ordered to ensure proper physical connectivity without relocating equipment.

Questions # 12:

What is the required PSU wattage for a FlashArray// X70R2/R3 or X90R2/R3 array?

Options:

1200W

1300W

1600W

Answer

Explanation

The FlashArray//X70R2 and //X90R2 models are equipped with dual 1600W power supplies, each rated for 1600 watts. These high-wattage power supplies are designed to support the increased performance and capacity demands of these models. The power supplies operate in an N+1 redundancy configuration, ensuring continuous operation even if one power supply fails.

Questions # 13:

An Implementation Engineer is assigned to install a 4X Module 9.1 TB Conversation Kit in a Flash Array Chassis. Why are there only four Direct Flash Modules?

Options:

To widen an existing write group.

To fill out enclosure bays.

To replace a missing shipment

Answer

Explanation

Installing four DirectFlash Modules in a 9.1 TB Conversion Kit is intended to widen an existing write group, improving performance and capacity distribution within the FlashArray.

Questions # 14:

A customer would like to consolidate their SAS shelves and wants to evacuate multiple shelves in parallel. What is a prerequisite for this procedure?

Options:

Purity must be upgraded to 6.x

The array chassis must be fully populated with modules.

The array usage percentage must be lower than 60%

Answer

Explanation

To evacuate multiple shelves in parallel safely during consolidation, the array’s usage must be sufficiently low (under 60%) to ensure enough free capacity for data movement.

Questions # 15:

A dark site customer requests an evacuation of SH01 on a FlashArray/M50. What is an appropriate next step?

Options:

Use the evac_checks script.

Ensure that usable capacity is less than 80%.

Ensure that usable capacity is less than 90%.

Answer

Explanation

Before evacuating a shelf on a FlashArray/M50, usable capacity should be below 80% to provide enough free space for safe data migration.

Questions # 16:

What command will view NVRAM install and update status?

Options:

purearray list

puredrive list

purehw list --all

Answer

Explanation

The command purehw list --all displays detailed hardware information, including NVRAM installation and update status on the FlashArray.

Questions # 17:

An Implementation Engineer performing an inventory of hardware for an NDU from an FlashArray//X70R2 to an FlashArray //X90R3 and discovers c complete FlashArray//X90R3 was shipped in place of an NDU kit. What is the minimum hardware the Implementation Engineer should use from this array to complete the NDU?

Options:

Controllers

Controller and power supplies

Controller and NVRAM

Answer

Explanation

For an NDU from FlashArray//X70R2 to //X90R3, the minimum required hardware from the shipped array is the controllers, which are swapped into the existing chassis and power infrastructure.

Questions # 18:

An Implementation Engineer is onsite to add two 4-port FC cards to a FlashArray//X20R3. In what state should the controller be in before performing the card add procedure?

Options:

Primary

Secondary

Standby

Answer

Explanation

The controller should be in the Secondary state before adding FC cards to ensure the primary controller remains operational and the procedure can be performed safely without disrupting services.

Questions # 19:

A customer has ordered several FlashArrays and wants to have ActiveCluster configured. What is the maximum quantity of arrays supported with ActiveCluster?

Options:

Answer

Explanation

FlashArray ActiveCluster is designed for synchronous replication between two FlashArray systems, enabling active-active configurations across two sites. This setup allows both arrays to serve I/O simultaneously, providing high availability and zero RPO (Recovery Point Objective). Each array in the ActiveCluster configuration maintains identical volume identities, ensuring seamless access for hosts regardless of the array they connect to. The configuration supports metro-area clustering, with a maximum round-trip latency of 11 milliseconds between arrays. Additionally, the Pure1 Cloud Mediator or an on-premises mediator is utilized to manage failover and prevent split-brain scenarios, eliminating the need for a third site or external gateway.

While ActiveCluster supports a two-site configuration, it does not support additional arrays within the same synchronous setup. For scenarios requiring protection across more than two sites, asynchronous replication solutions like ActiveDR™ can be employed. ActiveDR allows for asynchronous replication to a third site, providing broader disaster recovery capabilities.

Therefore, the maximum number of arrays supported in a single ActiveCluster configuration is two.

Questions # 20:

Prior to running the puresetup newarray command, which command should an Installation Engineer run on a new install of an //XR4 array?

Options:

pureboot list

cobalt_check.py

purehw list

Answer

Explanation

Running cobalt_check.py on a new //XR4 array verifies hardware and system readiness before executing puresetup newarray, ensuring a smooth setup process.
