NEW QUESTION # 22
An administrator wants to improve performance of heavily used volumes. What is the best approach?
Answer: D
Explanation:
Adding SDS nodes increases parallelism and improves performance. Reducing replication risks data protection.
NEW QUESTION # 23
A node failure occurs in a PowerFlex cluster. What ensures that data remains accessible?
Answer: D
NEW QUESTION # 24
What is the primary purpose of snapshots in PowerFlex?
Answer: A
Explanation:
* Enable point-in-time data recovery (Option B): A snapshot freezes the state of a volume at a specific second. If data is subsequently corrupted, deleted, or encrypted by ransomware, the administrator can use the snapshot to restore the data exactly as it was at that "point in time," minimizing data loss.
NEW QUESTION # 25
Which logical entity is used to group Storage Data Server (SDS) nodes for fault isolation and resource management?
Answer: B
Explanation:
The Protection Domain (PD) is the highest level of logical aggregation for storage nodes in PowerFlex.
* Fault Isolation: The Protection Domain acts as a "walled garden" for failures. If a catastrophic failure occurs (e.g., a power outage affecting a specific rack), the impact is contained within that Protection Domain. Data replication and rebuilding occur within the boundaries of the PD. An SDS in Protection Domain 1 cannot mirror data to an SDS in Protection Domain 2.
* Resource Management: Administrators manage resources at the PD level to balance the cluster. For example, a cluster might have one Protection Domain for "High Performance Flash" nodes and another PD for "High Capacity HDD" nodes.
* Differentiation:
* Storage Pools exist inside a Protection Domain to group disks.
* Fault Sets exist inside a Protection Domain to further granularize failure zones (e.g., preventing mirroring between nodes in the same rack).
NEW QUESTION # 26
A PowerFlex cluster shows degraded protection after a disk failure. What process restores redundancy?
Answer: C
Explanation:
The rebuild process redistributes data to restore redundancy after disk or node failure. Snapshots do not restore redundancy automatically.
