NEW QUESTION # 190
An Implementation Engineer has installed a data pack and the list command shows the drives in "unadmitted" status. Which command should the Implementation Engineer run to complete the admission?
Answer: B
Explanation:
When new capacity (a data pack) is physically installed into a FlashArray, the drives are detected by the system but are not automatically added to the storage pool to prevent accidental data overwrites or configuration errors. They appear in an "unadmitted" state.
To logically add these drives to the array's capacity, the Implementation Engineer must explicitly admit them. The command to perform this action is purearray drive admit (or puredrive admit in some contexts, but purearray drive admit is the specific option provided and valid). This command triggers the Purity software to format the new drives, add them to the system's write groups, and begin rebalancing data across the expanded capacity. Without running this admission command, the drives will remain visible but unusable for storage.

NEW QUESTION # 191
After an Implementation Engineer installs a new FlashArray and runs health checks, they see that Phonehome and Remote Assist are NOT working correctly. Which outbound port needs to be open for all management ports (physical and virtual)?
Answer: B
Explanation:
For PhoneHome (telemetry) and Remote Assist (support tunnels) to function correctly, TCP Port 443 (HTTPS) must be open for outbound traffic from all management ports (CT0.ETH0, CT1.ETH0, and the Virtual Management IP).
Pure Storage utilizes a secure, encrypted connection to communicate with the Pure1 Cloud and Support infrastructure.
PhoneHome: The array sends logs and heartbeat data to purestorage.com (and associated subdomains) via HTTPS over Port 443. If this port is blocked, the array cannot report its health status, preventing proactive support.
Remote Assist: This feature creates a reverse SSH tunnel encapsulated over HTTPS (websocket or similar secure transport) to allow Pure Support to remotely log in. It initiates the connection outbound to the support relay servers on Port 443.
Option A (Port 80) is generally not used for secure management traffic in modern configurations, often only serving as a redirect. Option C (Port 123) is required for NTP (Network Time Protocol) synchronization, which is critical for logs but is not the transport port for the PhoneHome/Remote Assist data stream itself. Therefore, verifying firewall rules for Port 443 is the primary troubleshooting step.
NEW QUESTION # 192
An Implementation Engineer is performing a FlashArray//XR4 to FlashArray//XL upgrade, and is preparing to remove the XR4 CT0 controller. Which command should the Implementation Engineer run to stop Purity after confirming CT0 is the secondary controller?
Answer: C
Explanation:
The upgrade from a FlashArray//XR4 to a FlashArray//XL is a specific "Data-in-Place" hardware migration that utilizes the purewes (Pure Workflow Execution Service) utility to orchestrate complex steps. One of the most critical steps involves stopping the Purity software stack on the controller that is about to be removed (CT0) to ensure a clean failover and data flush to the surviving controller.
The correct command syntax is purewes controller disable --purity --verify-mode secondary --verify-array ARRAY_NAME ct0.
purewes controller disable: Initiates the shutdown of the controller's services.
--purity: Specifies that the Purity software stack should be stopped (not just the hardware).
--verify-mode secondary: This is a crucial safety check. It ensures the command only executes if CT0 is currently the Secondary controller. If CT0 were Primary, running this command without a failover first would cause an outage.
--verify-array: Confirms the action is being taken on the correct target array.
This command sequence ensures the controller is safely quiesced before the Implementation Engineer physically removes it from the chassis.
=========
NEW QUESTION # 193
Before proceeding with a controller upgrade, phonehome logs must be sent. What command will verify that the logs have been sent?
Answer: A
Explanation:
To verify the history and transmission status of Phonehome log bundles, the correct command is purearray phonehome --list.
Before starting a controller upgrade (NDU), it is mandatory to ensure that the array can successfully transmit diagnostic data to Pure Storage. This allows Support to review the "pre-flight" checks and ensures that if an issue occurs during the upgrade, logs will be available for triage.
Usage: Running purearray phonehome --list displays a table of recent log bundles generated by the system.
Verification: The Engineer must look at the Status column for the most recent entries. A status of "uploaded" confirms that the array has successfully connected to the Pure Storage cloud and transferred the data. If the status is "queued" or "failed," the upgrade should not proceed until network connectivity (firewall/proxy) is resolved. Options A and C are incorrect CLI syntax for this specific verification task.
NEW QUESTION # 194
An Implementation Engineer is getting ready to install four DFMs into a 16-module efficiency bundle and notices that the new modules are DFMDs while the installed modules are DFMs. What should the Implementation Engineer do to get the array using a 20-module Wide write group?
Answer: B
Explanation:
FlashArray performance and capacity efficiency are optimized when drives are grouped into "Wide Write Groups" (typically 20 modules). Purity OS generally enforces strict homogeneity within a write group to ensure consistent performance and reliability. Specifically, mixing standard DirectFlash Modules (DFM) with DirectFlash Modules with Distributed NVRAM (DFMD) in the same write group is restricted by default because of the architectural differences in how they handle persistent memory and I/O acknowledgment.
However, in upgrade scenarios where a customer is expanding an existing 16-module DFM group to a 20- module group using newer DFMD spares or expansion packs, Purity includes an engineering tunable to permit this mixed configuration. The correct procedure is to physically install the new DFMDs and run the admission command. Because of the mix, the array might initially hesitate or create a separate group. To force the creation of a single 20-drive Wide Write Group (WWG) , the Implementation Engineer must work with Pure Storage Support to apply the specific tunable puretune --set ALLOW_DFMD_IN_DFM_WWG 1 .
This overrides the default restriction, allowing the system to merge the disparate module types into a single, high-efficiency capacity pool.
