EMC Dell PowerFlex Operate Exam Sample Questions (Q62-Q67):NEW QUESTION # 62
What are the benefits of enabling Maintenance Mode on a PowerFlex node? (Choose two).
Answer: B,C
Explanation:
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.

NEW QUESTION # 63
What is the minimum number of nodes required for creating a Fault Set in PowerFlex?
Answer: A
Explanation:
* 6 Nodes: To utilize the Fault Set feature (which provides higher availability than standard SDS grouping, typically for rack awareness), PowerFlex requires a minimum configuration.
* The Math:
* A Protection Domain requires a minimum of 3 Fault Sets to support the 2-copy mirroring (Primary, Secondary, and a third location for rebuilding if a set fails).
* Dell PowerFlex engineering requirements state that each Fault Set must contain at least 2 SDS nodes to ensure local redundancy and performance balance within the set.
* $3         ext{ Fault Sets}         imes 2         ext{ Nodes} = 6         ext{ Nodes}$ minimum.

NEW QUESTION # 64
Which tasks can be performed using Dynamic Node Addition in PowerFlex? (Choose two).
Answer: B,C
Explanation:
Dynamic Node Addition is the process of scaling out the cluster by adding more physical servers.
* Expand storage capacity (Option A): When a new node running the SDS (Storage Data Server) service is added, its local drives are added to the Storage Pool. PowerFlex automatically rebalances data to these new drives, increasing the total usable capacity of the cluster.
* Increase compute resources (Option C): In an HCI (Hyper-Converged Infrastructure) deployment, adding a node adds not just storage, but also CPU and RAM available for running applications or VMs (Compute). Even in a two-layer configuration, adding a compute-only node (SDC) increases compute resources.

NEW QUESTION # 65
What are the benefits of using shared file systems in PowerFlex? (Choose two).
Answer: A,B
Explanation:
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.

NEW QUESTION # 66
What is the default state of snapshots created in PowerFlex?
Answer: A
Explanation:
* Editable (Writable): Unlike many traditional storage arrays where a snapshot is a read-only frozen image requiring a "clone" to become writable, PowerFlex snapshots are fully writable volumes by default.
* Behavior: Immediately upon creation, a snapshot is mapped as a volume. You can mount it to a host, write new data to it, delete files from it, or format it, without affecting the source parent volume (due to the Redirect-on-Write architecture).

NEW QUESTION # 67
