최신 Converged Infrastructure D-PWF-OE-00 무료샘플문제 (Q45-Q50):

질문 # 45
Which task is a valid operation for manipulating volumes in PowerFlex?

정답：B

설명：
Administrators perform various operations on Volumes to manage data lifecycles.
* Create snapshots of the volume (Option B): This is a standard Day-2 operation. A user can select a volume and trigger a snapshot (or a consistency group snapshot). This creates a point-in-time, writable copy of the volume instantly.
* Why others are incorrect:
* Fault Sets (A): Volumes are not assigned to Fault Sets. SDS nodes are assigned to Fault Sets.
Volumes live in Storage Pools.
* VLAN tagging (C): VLANs are configured on the SDC (client) network interfaces or the switch, not on the storage volume itself.
* Add to MDM (D): The MDM manages the volume map, but you do not manually "add" a volume to an MDM; you create a volume via the MDM.


질문 # 46
What are the benefits of using snapshots in PowerFlex? (Choose two).

정답：A,B

설명：
* Enable quick data recovery (Option A): Snapshots provide a "rewind" button. If a database is corrupted or a file is accidentally deleted at 2:00 PM, an administrator can instantly restore the volume to the state captured in the 1:00 PM snapshot.
* Create a point-in-time copy of data (Option D): This is the definition of a snapshot. It freezes the view of the data at a specific second. This is crucial for backups (backup software backs up the static snapshot while the production application continues to write to the live volume) or for creating test/dev clones of production data.


질문 # 47
Shared file systems in PowerFlex allow data sharing across multiple nodes.

정답：B

설명：
This refers to PowerFlex File (formerly PowerFlex NAS).
While the core PowerFlex product is a block storage solution (providing raw LUNs/Volumes which cannot be safely shared by two standard OS hosts without a cluster file system like VMFS or OCFS2), PowerFlex File introduces NAS nodes. These nodes format the block storage and present it via NFS or SMB protocols. These protocols are specifically designed to allow multiple clients to read and write to the same file system concurrently, enabling true data sharing across the network.


질문 # 48
Which configurations are necessary for using storage data targets in PowerFlex? (Choose two).

정답：B,C

설명：
In the context of PowerFlex, "Storage Data Targets" typically refers to the Storage Data Servers (SDS) or the physical nodes providing capacity.
* Configure IP connectivity (Option A): For an SDS (Target) to function, it must have valid IP connectivity over the data network to communicate with the SDCs (Clients) and other SDSs (for mesh mirroring). Without proper IP configuration (and VLAN tagging), the storage cannot be accessed.
* Validate target device compatibility (Option D): Before assigning storage devices (drives) to an SDS, it is critical to validate that the devices are on the Hardware Compatibility List (HCL) and are of a consistent type (e.g., all NVMe or all SAS SSD). Incompatible or mixed-performance devices can degrade the performance of the entire Storage Pool.
Incorrect Options: Deduplication (B) is a pool-level setting, not a "target" connectivity setting. You assign SDSs to Protection Domains (C), but you do not "assign targets" in the way external arrays function; the SDS is the target.


질문 # 49
Which management interface is used for day-to-day operations of PowerFlex?

정답：A

설명：
Note: In the context of PowerFlex exams, there is often a distinction between "Lifecycle Management" (PowerFlex Manager) and "Block Storage Operations" (GUI/Presentation Server).
* GUI (Option C): The PowerFlex Web UI (often accessed via the Presentation Server or the unified dashboard in v4) is the primary tool for Day-to-Day tasks. This includes mapping volumes to hosts, taking snapshots, monitoring IOPS, and checking capacity usage. It provides the visual topology of the storage.
* PowerFlex Manager (D): While modern versions unify this, historically and in exam logic, PFxM is the tool for deployment, upgrades, and hardware alerts (Lifecycle), whereas the "GUI" is for storage management.
The CLI (B) is used for scripting and advanced tasks, but the GUI is the standard for general daily operations.
