質問 # 85
What is the minimum number of nodes required to create a Storage Data Server (SDS)?
正解：C
解説：
* 3 Nodes: While you can technically install the SDS software on a single server, to create a functioning Storage Pool and a valid PowerFlex cluster that supports the standard 2-copy mesh-mirroring protection scheme, a minimum of 3 SDS nodes is required.
* Why? Data is divided into chunks (Primary and Secondary).
* Chunk A Primary goes to Node 1.
* Chunk A Secondary goes to Node 2.
* If Node 1 fails, the system needs a third node (Node 3) to rebuild the missing copy from Node 2 to restore redundancy. A 2-node cluster cannot rebuild data if one node fails (nowhere to put the copy), leaving it permanently degraded.
質問 # 86
A Fault Set in PowerFlex requires a minimum of 3 nodes to ensure fault tolerance. True or False?
正解：A
解説：
To utilize Fault Sets effectively for their intended purpose (rack-level fault tolerance), the cluster architecture imposes specific minimums.
PowerFlex relies on distributing data copies (Mesh Mirroring). The standard redundancy scheme creates 2 copies of data. To ensure that data remains available even if one entire Fault Set (e.g., an entire rack) fails, the system must be able to distribute the mirrors across different Fault Sets. Consequently, you generally need a minimum of 3 Fault Sets (System requires 3+ Fault Sets to support 2-copy layouts effectively). Since a Fault Set must contain at least one node, the cluster requires a minimum of 3 nodes to support a Fault Set configuration.
質問 # 87
Which tasks are automated when configuring snapshots in PowerFlex? (Choose two).
正解：A、B
解説：
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.
質問 # 88
What are the considerations for configuring new Metadata Managers during cluster expansion?
(Choose two).
正解：A、D
解説：
The Metadata Manager (MDM) cluster is the critical control plane of PowerFlex.
Maintain redundancy for metadata storage (Option D): The MDM cluster (typically 3 or 5 nodes) must always maintain a quorum. When reconfiguring or expanding the management capabilities, you must ensure that there are enough replicas (Primary, Secondary, Tie-Breakers) to survive a node failure without bringing down the cluster management.
Ensure even distribution (Option A): Best practice dictates that MDM roles should be distributed across different failure domains (different racks or chassis) to prevent a single physical failure (like a rack power outage) from taking down the entire MDM cluster simultaneously.
質問 # 89
What is the primary benefit of PowerFlex architecture?
正解：B
解説：
PowerFlex provides software-defined storage that scales linearly, integrating compute and storage resources for flexibility and performance.
