質問 # 81
How can an administrator monitor the specific progress of a PowerFlex cluster upgrade?
正解：B
解説：
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.
質問 # 82
An administrator is monitoring a PowerFlex cluster and notices increased latency on certain volumes. The SDS and SDC components appear healthy. The administrator needs to identify whether the issue is related to backend disk performance or network congestion. Which tool should be used first?
正解：A
解説：
The PowerFlex GUI provides built-in performance monitoring dashboards, including latency, IOPS, and throughput metrics. It allows administrators to quickly identify whether bottlenecks originate from disks or network paths. CLI and OS logs provide detail but are less efficient for initial diagnosis.
質問 # 83
What is the benefit of enabling deduplication in PowerFlex storage?
正解：D
解説：
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).
質問 # 84
What are the prerequisites for creating a Fault Set? (Choose two).
正解：C、D
解説：
Fault Sets are a logical subdivision within a Protection Domain used to increase availability (e.g., ensuring that the three copies of data reside in three different racks).
* Predefined Protection Domain (Option B): Fault Sets exist inside a Protection Domain. You cannot create a Fault Set floating in the void; it must be assigned to a parent Protection Domain.
* At least 3 nodes in the cluster (Option A): PowerFlex uses a mesh-mirroring architecture. To guarantee availability, the system generally requires a minimum of 3 Fault Sets (so that if one fails, the data can be rebuilt to the other two). Since a Fault Set must contain at least one node, this implies a minimum requirement of 3 nodes (one per Fault Set) to utilize the feature effectively.
Note on Option C: You typically define Fault Sets before creating Storage Pools or adding SDSs in a greenfield deployment. If Storage Pools already exist, converting to Fault Sets is complex/restricted, so
"Existing Storage Pool" is not a prerequisite for creating the Fault Set structure itself.
質問 # 85
What is the primary purpose of a Protection Domain in PowerFlex?
正解：C
解説：
The Protection Domain (PD) is the fundamental unit of fault isolation.
* Isolating storage resources for fault containment (Option B): The PowerFlex mesh-mirroring algorithm works only within a Protection Domain. Data on Node A (in PD1) will only be mirrored to other nodes inside PD1. It will never be mirrored to PD2.
* Why is this important? If a catastrophic software bug or a massive power surge affects one Protection Domain, the damage is contained there. The other Protection Domains continue to function normally. It allows administrators to segment the cluster (e.g., PD_Production vs. PD_Test) to ensure that issues in one environment do not bleed into another.
