EMC Dell PowerFlex Operate Exam Sample Questions (Q21-Q26):NEW QUESTION # 21
What type of authentication is supported for managing user accounts in PowerFlex?
  • A. TACACS+
  • B. RADIUS
  • C. LDAP
  • D. SAML
Answer: C
Explanation:
LDAP (Lightweight Directory Access Protocol) is the primary external authentication method supported by the PowerFlex core (MDM) for managing user access.
* Integration: PowerFlex can be configured to query an Active Directory or OpenLDAP server. This allows administrators to map AD Groups (e.g., "Storage Admins") to PowerFlex roles (e.g.,
"SuperUser"), centralizing password management and user termination.
* Note on SAML: While PowerFlex Manager (the management platform) and newer versions (v4.x) support SAML/OIDC for Single Sign-On, LDAP remains the fundamental answer for core authentication in most exam contexts unless specifically asking about PowerFlex Manager 4.0 Identity Management. TACACS+ and RADIUS are network-centric protocols and are generally not supported by the PowerFlex storage core.

NEW QUESTION # 22
What is the benefit of enabling deduplication in PowerFlex storage?
  • A. Increases node discovery rates
  • B. Ensures fault tolerance
  • C. Reduces data redundancy and capacity footprint
  • D. Enhances data replication speed
Answer: C
Explanation:
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).

NEW QUESTION # 23
What is the minimum number of nodes required to create a Storage Data Server (SDS)?
  • A. 0
  • B. 1
  • C. 2
  • D. 3
Answer: A
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 # 24
What actions are taken when reconfiguring Storage Data Servers during cluster expansion? (Choose two).
  • A. Reallocate storage pools for load balancing
  • B. Validate new node compatibility with existing SDS configurations
  • C. Configure Fault Sets for the new nodes
  • D. Enable data deduplication on new SDS nodes
Answer: B,C
Explanation:
When expanding a cluster by adding new Storage Data Server (SDS) nodes:
* Validate new node compatibility (Option A): Before adding a node, you must ensure it matches the hardware compatibility list (HCL). More importantly, to prevent performance bottlenecks ("stragglers"), the new nodes should ideally match the CPU, RAM, and most importantly, the drive type
/performance of the existing nodes in the Storage Pool.
* Configure Fault Sets for the new nodes (Option C): If the cluster is configured to use Fault Sets (which is recommended for larger clusters to ensure rack-level availability), the new node must be explicitly assigned to a specific Fault Set before it is added. You cannot add a node to a Protection Domain that uses Fault Sets without specifying which Fault Set it belongs to.
Incorrect Options: Option B describes "Rebalance," which is an automatic background process, not a manual
"reallocation" action. Option D is incorrect because deduplication is a pool-wide setting; you do not enable it on a per-node basis.

NEW QUESTION # 25
What are the benefits of using snapshots in PowerFlex? (Choose two).
  • A. Enable quick data recovery
  • B. Minimize storage capacity usage
  • C. Create a point-in-time copy of data
  • D. Reduce fault tolerance across clusters
Answer: A,C
Explanation:
* Enable quick data recovery (Option A): Snapshots provide a "rewind" button. If a database is corrupted or a file is accidentally deleted at 2:00 PM, an administrator can instantly restore the volume to the state captured in the 1:00 PM snapshot.
* Create a point-in-time copy of data (Option D): This is the definition of a snapshot. It freezes the view of the data at a specific second. This is crucial for backups (backup software backs up the static snapshot while the production application continues to write to the live volume) or for creating test/dev clones of production data.
