問題 #99
An administrator wants to configure a shared file system in PowerFlex. What steps should they follow?
(Select two).
答案：A,C
解題說明：
Configuring PowerFlex File (NAS) involves creating the logical file system and then defining how clients access it.
* Create the shared file system using the GUI (Option A): The administrator uses the PowerFlex Manager (or Block UI) to define the file system properties, such as name, size, and the Storage Pool it will consume capacity from.
* Configure multi-node access permissions (Option C): Once the file system exists, it is not accessible until it is "Exported" (NFS) or "Shared" (SMB). During this step, the administrator must configure the access control lists (ACLs) or export policies that define which client IPs or Subnets (nodes) are allowed to mount the file system and whether they have Read-Only or Read-Write permissions.
問題 #100
Which operations are supported for managing snapshots in PowerFlex? (Choose two).
答案：B,D
解題說明：
PowerFlex offers robust snapshot management capabilities accessible via the PowerFlex Manager UI, CLI (SCLI), and REST API.
* Schedule automatic snapshot creation (Option D): PowerFlex supports Snapshot Policies.
Administrators can define policies that automatically generate snapshots at specific intervals (e.g., every hour, daily, or weekly) and define retention rules (how many snapshots to keep). This automation is critical for meeting Recovery Point Objectives (RPO) without manual intervention.
* Restore data from a snapshot (Option A): PowerFlex allows administrators to restore a volume to a previous state using a snapshot. In the CLI, this is often handled by the command overwrite_volume_content, where the content of the production volume is replaced by the data in the snapshot. This is essential for recovering from data corruption or ransomware events.
Why not B? In PowerFlex, snapshots are already writable volumes by default immediately upon creation.
There is no need to "convert" them; they can be mapped to a host and written to instantly.
Why not C? Deduplication is a property of the Storage Pool (specifically in Fine Granularity pools), not a specific operation triggered on a snapshot.
問題 #101
What is the recommended method for performing a fully automated upgrade of a PowerFlex cluster?
答案：C
解題說明：
PowerFlex Manager (PFxM) is specifically designed to handle the complexity of the lifecycle management (LCM) for the solution.
The recommended method is using PFxM LCM because:
Orchestration: It automatically determines the correct order of operations (e.g., MDM
$\rightarrow$ SDS $\rightarrow$ SDC).
Safety: It ensures the cluster is healthy before proceeding. It automatically places nodes into Maintenance Mode (PMM) to ensure data redundancy is maintained throughout the process.
Compliance: It checks the nodes against a "Compliance File" (RCM - Release Certification Matrix) to ensure that the BIOS, Firmware, Drivers, and OS match the PowerFlex software version.
問題 #102
What are the key steps required when creating a Storage Pool in PowerFlex? (Choose two)
答案：A,B
解題說明：
Creating a Storage Pool is a foundational step in configuring PowerFlex, as it defines the physical capacity available for volume creation.
* Define the Protection Domain (Option B): PowerFlex utilizes a strict hierarchy. Top Level
$\rightarrow$ Protection Domain (PD) $\rightarrow$ Storage Pool (SP). You cannot create a Storage Pool without first identifying which Protection Domain it resides in. The Protection Domain groups a specific set of SDS (Storage Data Server) nodes. The Storage Pool creates a logical subset of drives within those nodes.
* Assign drives with consistent performance metrics (Option D): This is a critical best practice and requirement. PowerFlex distributes data chunks (mesh mirroring) across all drives in a Storage Pool. If you mix NVMe SSDs with slow SATA HDDs in the same pool, the performance of the entire pool will drop to the speed of the slowest drive (the "straggler" effect). Therefore, a Storage Pool must consist of homogeneous media types (e.g., all SAS SSDs or all NVMe) to ensure predictable and consistent IOPS and latency.
問題 #103
What are the benefits of using shared file systems in PowerFlex? (Choose two).
答案：A,D
解題說明：
PowerFlex File (NAS) is designed for concurrent access.
* Simplifies data sharing between nodes (Option A): The core benefit of a shared file system (NFS
/SMB) is that multiple compute nodes (Clients) can access the exact same files simultaneously. This is essential for clustered applications, user home directories, or shared logs.
* Provides high availability for shared data (Option D): PowerFlex File uses clustered NAS headers (NAS Nodes). If one NAS node fails, the IP address and file handles are automatically failed over to a surviving NAS node. This ensures that clients do not lose access to the data, maintaining high availability.
問題 #104
