Which specific operations can be performed on PowerFlex volumes? (Choose two)
A. Assign volumes to Protection Domains
B. Enable data replication
C. Create snapshots
D. Configure VLAN tagging directly on the volume
答案:B,C
解題說明:
PowerFlex Volumes are block-level storage devices mapped to hosts.
* Create Snapshots (Option A): Snapshots are point-in-time copies of a volume. In PowerFlex, snapshots are writable and instantaneous. They share the same data blocks as the source volume until changes are made (Redirect-on-Write). They are essential for backups, testing/dev environments, and creating clones.
* Enable Data Replication (Option D): PowerFlex supports native asynchronous and synchronous replication. This is configured at the Volume level (or via Consistency Groups containing volumes).
You select a volume and pair it with a destination volume on a remote PowerFlex cluster to ensure disaster recovery.
Incorrect Options:
* VLAN tagging (B): This is a network configuration performed at the OS/Switch/Interface level, not on a storage block volume.
* Assign to PD (C): Volumes reside inside a Storage Pool, which resides inside a Protection Domain.
You assign a volume to a Storage Pool upon creation, not directly to a Protection Domain.
問題 #55
What is the benefit of enabling deduplication in PowerFlex storage?
A. Enhances data replication speed
B. Ensures fault tolerance
C. Increases node discovery rates
D. Reduces data redundancy and capacity footprint
答案:D
解題說明:
Deduplication (often paired with compression) is an efficiency feature available in PowerFlex Fine Granularity (FG) storage pools.
* Reduces data redundancy (Option A): The primary purpose of inline deduplication is to identify repeated data patterns (blocks) as they are written to the system. Instead of writing the same 4KB block of zeroes or identical OS files multiple times, PowerFlex writes it once and creates pointers for subsequent writes. This significantly reduces the physical storage capacity required to store data, particularly in VDI (Virtual Desktop Infrastructure) or virtualized server environments where many VMs share similar OS files.
Note: Deduplication is a trade-off; it saves space but requires more CPU/RAM overhead on the Storage Data Servers (SDS).
問題 #56
What are the benefits of enabling Maintenance Mode on a PowerFlex node? (Choose two).
A. Enables faster deduplication processes
B. Isolates the node for troubleshooting
C. Automatically replicates data to other nodes
D. Allows for node hardware upgrades without disrupting operations
答案:C,D
解題說明:
This question refers specifically to Protected Maintenance Mode (PMM), which is the standard operational procedure for node maintenance.
* Allows for node hardware upgrades without disrupting operations (Option A): This is the primary business benefit. By placing a node in PMM, you can power it down to replace a failed DIMM, upgrade a CPU, or update firmware. The cluster continues to serve I/O to applications without downtime.
* Automatically replicates data to other nodes (Option B): This is the technical mechanism that makes PMM safe. When PMM is requested, the PowerFlex system identifies the data chunks residing on that node. It proactively copies (mesh-mirrors) that data to other available nodes in the cluster before the node is allowed to go offline. This ensures that even while the node is down for maintenance, the cluster retains full data redundancy (usually 2 copies).
Option C is a side effect but not the primary "benefit" compared to data safety. Option D is incorrect; maintenance mode consumes resources for rebalancing/replication and does not speed up deduplication.
問題 #57
How can an administrator monitor the specific progress of a PowerFlex cluster upgrade?
A. Through the PowerFlex Manager (PFxM) UI
B. By accessing storage pool logs directly
C. Using the PowerFlex CLI only
D. Using the vCenter Plugin
答案:A
解題說明:
While the PowerFlex CLI (SCLI) can provide the status of individual components, PowerFlex Manager (PFxM) is the designated interface for initiating, managing, and monitoring the full stack upgrade process.
When an upgrade is initiated via PFxM, the interface provides a dedicated Job Details or Service Details view. This view offers a granular, step-by-step progress indicator. It visualizes the orchestration logic:
* Validating the system health.
* Placing a specific node into Protected Maintenance Mode (PMM).
* Applying firmware and software updates.
* Rebooting the node.
* Verifying the node has rejoined the cluster and data is rebalanced.
* Moving to the next node.
This automation reduces the risk of human error. The GUI provides a clear percentage complete and highlights any errors or warnings immediately, making it the primary tool for monitoring upgrades compared to parsing raw logs or running repetitive CLI commands.
問題 #58
What are the benefits of using shared file systems in PowerFlex? (Choose two).
A. Simplifies data sharing between nodes
B. Provides high availability for shared data
C. Enhances fault tolerance
D. Enables deduplication and compression
答案:A,B
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.
