EMC Dell PowerFlex Operate Exam Sample Questions (Q72-Q77):NEW QUESTION # 72
Which characteristics define a Fault Set in PowerFlex? (Choose two).
  • A. Contains metadata for storage pools
  • B. Ensures data availability during node failure
  • C. Requires a minimum of 3 nodes
  • D. Is limited to a single Protection Domain
Answer: B,D
Explanation:
* Is limited to a single Protection Domain (Option D): A Fault Set is a logical subdivision within a Protection Domain. You cannot span a Fault Set across multiple Protection Domains.
* Ensures data availability (Option B): The purpose of a Fault Set is to simulate "Rack Awareness." PowerFlex ensures that copies of data (mirrors) are never placed in the same Fault Set. If Fault Set 1 (Rack 1) fails completely, the system guarantees that the secondary copies of that data exist in Fault Set
2 or 3, keeping the data available.
Note on C: While a cluster using Fault Sets requires 3+ nodes total, the definition of the Fault Set itself is about availability (B) and its hierarchy (D).

NEW QUESTION # 73
What is the minimum number of nodes required to create a Storage Data Server (SDS)?
  • A. 0
  • B. 1
  • C. 2
  • D. 3
Answer: C
Explanation:
* 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.

NEW QUESTION # 74
Which logical entity is used to group Storage Data Server (SDS) nodes for fault isolation and resource management?
  • A. Resource Groups
  • B. Protection Domains
  • C. Storage Pools
  • D. Fault Sets
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 # 75
Which actions can be performed within a Protection Domain? (Choose two).
  • A. Group nodes for metadata management
  • B. Create multiple Storage Pools
  • C. Enable automatic volume snapshots
  • D. Monitor fault tolerance compliance
Answer: B,D
Explanation:
* Create multiple Storage Pools (Option A): A Protection Domain (PD) is a container for nodes. Inside that container, you can define multiple storage pools (e.g., "PD1_Performance_Pool" and
"PD1_Capacity_Pool") to segregate media types within the same group of servers.
* Monitor fault tolerance compliance (Option B): Since the PD is the boundary for mesh mirroring, you monitor the health and rebuild status at the PD level. If a node fails, you monitor the PD to see the
"Rebuild Progress" to ensure fault tolerance is restored.
Incorrect Options: Nodes are grouped for storage (SDS), not metadata management (C). Snapshots (D) are enabled on Volumes, not on the Protection Domain object itself.

NEW QUESTION # 76
Which feature of PowerFlex is leveraged to expand storage capacity in a cluster?
  • A. Snapshots
  • B. Shared File Systems
  • C. Dynamic Node Addition
  • D. Fault Sets
Answer: C
Explanation:
PowerFlex is a scale-out architecture.
* Dynamic Node Addition (Option B): This refers to the ability to add new x86 servers (nodes) to the cluster on the fly. When you add a node with local drives, the PowerFlex software automatically recognizes the new capacity. It then initiates a Rebalance operation, moving data chunks from existing full nodes to the new empty node until usage is uniform across the cluster. This process increases both Storage Capacity and Performance (IOPS/Bandwidth) linearly.
Incorrect Options:
* Fault Sets (A) organize nodes for availability, they do not add capacity.
* Snapshots (C) consume capacity.
* Shared File Systems (D) manage how capacity is accessed (NAS), not the expansion of the raw block layer.
