NEW QUESTION # 24
A PowerFlex cluster experiences uneven capacity distribution across SDS nodes. Which feature should be used to rebalance data?
Answer: D
Explanation:
The rebalance operation redistributes data evenly across SDS nodes, optimizing capacity and performance. Manual migration is inefficient and error-prone, while snapshots and volume remapping do not address distribution issues.
NEW QUESTION # 25
What steps are required to configure a Storage Pool? (Choose two).
Answer: B,D
Explanation:
A Storage Pool is a logical entity that aggregates the capacity of physical devices.
* Define the Protection Domain (Option A): The Storage Pool hierarchy is strict. You must first create a Protection Domain (PD), which groups the SDS nodes. The Storage Pool is then created within that Protection Domain. You cannot create a Storage Pool without this parent container.
* Assign drives with similar performance characteristics (Option B): This is a critical configuration requirement. PowerFlex stripes data across all drives in a pool. If you mix NVMe and SATA drives in the same pool, the fast NVMe drives will wait for the slow SATA drives, dragging the entire pool's performance down to the lowest common denominator (the "straggler" effect). Therefore, standard procedure is to create separate pools for separate media types (e.g., "Performance_Pool" for NVMe,
"Capacity_Pool" for HDD).
NEW QUESTION # 26
Which component is reconfigured when expanding metadata storage in PowerFlex?
Answer: D
Explanation:
Metadata in PowerFlex is not stored in the general user Storage Pools; it is managed and stored by the Metadata Manager (MDM) cluster.
When a PowerFlex cluster grows significantly (e.g., increasing from 1000 to 100,000 volumes, or adding hundreds of nodes), the metadata usage increases.
Expanding Metadata Capabilities: You do not "expand" a metadata pool like you do a storage pool. Instead, you might reconfigure the MDM Cluster itself. This could involve moving from a 3- node MDM cluster to a 5-node MDM cluster to distribute the processing load, or replacing the MDM nodes with hardware possessing larger RAM and faster CPUs.
Therefore, the component being reconfigured to handle this growth is the Metadata Manager (MDM).
NEW QUESTION # 27
Which steps are necessary before initiating a PowerFlex upgrade? (Choose two).
Answer: A,B
Explanation:
Preparation is key to a safe upgrade.
* Back up the cluster configuration (Option C): Before making any changes, administrators should perform a backup of the MDM Cluster configuration. This creates a recovery point for the system's metadata (mappings, settings, user accounts) in case a catastrophic failure occurs during the upgrade.
* Verify node hardware compatibility (Option A): Administrators must ensure that the hardware (server model, CPU, NICs) and the current firmware levels are compatible with the new PowerFlex software version. Running the Health Check or Pre-Upgrade Validation tool will confirm if the nodes meet the strict requirements (HCL) for the target version.
Incorrect Options: Creating snapshots of all volumes (B) is not a system upgrade requirement (though good for data safety, it's not part of the upgrade procedure itself). Reconfiguring fault sets (D) is a structural change, not a pre-upgrade step.
NEW QUESTION # 28
Which tasks are automated when configuring snapshots in PowerFlex? (Choose two).
Answer: A,B
Explanation:
These tasks are handled by the Snapshot Policy feature in PowerFlex.
* Scheduling snapshot creation (Option A): Administrators can define a policy (e.g., "Gold Policy") that triggers a snapshot every 15 minutes. Once applied to a volume, the system automates this trigger.
* Managing snapshot retention policies (Option C): The policy also dictates the lifecycle of the snapshot. For example, "Keep 10 hourly snapshots and 5 daily snapshots." As new snapshots are created, the system automatically deletes the oldest ones to free up space and maintain the defined retention count.
Incorrect Options:
* Assigning to Fault Sets (B): Snapshots reside in the same Storage Pool as the source volume; they are not assigned to Fault Sets.
* Automating replication (D): While replication uses snapshots, the Snapshot Policy feature itself is distinct from the Replication Consistency Group configuration.
