EMC Dell PowerFlex Operate Exam Sample Questions (Q62-Q67):NEW QUESTION # 62
Which tasks can be performed using PowerFlex Manager (PFxM)? (Choose two)
  • A. Backup and recovery configuration
  • B. Lifecycle management (LCM) of nodes
  • C. Virtual machine migration (vMotion)
  • D. Monitoring cluster performance and health
Answer: B,D
Explanation:
PowerFlex Manager (PFxM) is the unified management and orchestration tool for the PowerFlex environment. Its capabilities are distinct from virtualization managers like vCenter or backup software like PowerProtect.
* Lifecycle Management (LCM): This is a core function of PFxM. It automates the entire lifecycle of the hardware and software stack. This includes discovering nodes, defining services (templates), and automating the complex process of upgrades. PFxM orchestrates non-disruptive upgrades (NDU) by interacting with the nodes to enter Maintenance Mode, update firmware/BIOS/OS/PowerFlex software, and return them to service sequentially.
* Monitoring Cluster Performance and Health: PFxM acts as a central dashboard. It aggregates alerts, events, and performance metrics from the underlying PowerFlex cluster. It provides health scores for the System, Compliance, and Resources, allowing administrators to visually identify bottlenecks or hardware failures (like a failed drive or disconnected NIC) in real-time.
Option A is a function of VMware vCenter, and Option C is typically handled by backup specific software, although PowerFlex supports snapshotting.

NEW QUESTION # 63
While setting up a PowerFlex cluster, an administrator needs to create a Storage Pool. What tasks must they complete first?
  • A. Enable Fault Sets for redundancy
  • B. Configure a Protection Domain
  • C. Assign drives with consistent performance metrics
  • D. Validate VLAN configurations
Answer: B
Explanation:
This question tests your knowledge of the logical hierarchy in PowerFlex:
System $ightarrow$ Protection Domain $ightarrow$ Storage Pool $ightarrow$ Device (Disk)
$ightarrow$ Volume.
* Configure a Protection Domain (Option A): You cannot create a Storage Pool without a parent entity. The Protection Domain (PD) is the container that isolates a specific group of nodes. Once the PD is created, you create a Storage Pool inside it.
* The Workflow:
* Install SDS software on nodes.
* Create a Protection Domain (e.g., PD_1).
* Add SDS nodes to PD_1.
* Create a Storage Pool (e.g., Pool_SSD) inside PD_1.
* Add devices (drives) to Pool_SSD.
Options B and C are important validation steps, but A is the mandatory structural prerequisite.

NEW QUESTION # 64
What is the primary purpose of a Protection Domain in PowerFlex?
  • A. Grouping nodes based on geographical location
  • B. Managing metadata for storage pools
  • C. Configuring node maintenance schedules
  • D. Isolating storage resources for fault containment
Answer: D
Explanation:
The Protection Domain (PD) is the fundamental unit of fault isolation.
* Isolating storage resources for fault containment (Option B): The PowerFlex mesh-mirroring algorithm works only within a Protection Domain. Data on Node A (in PD1) will only be mirrored to other nodes inside PD1. It will never be mirrored to PD2.
* Why is this important? If a catastrophic software bug or a massive power surge affects one Protection Domain, the damage is contained there. The other Protection Domains continue to function normally. It allows administrators to segment the cluster (e.g., PD_Production vs. PD_Test) to ensure that issues in one environment do not bleed into another.

NEW QUESTION # 65
What is the primary function of alerting in PowerFlex security?
  • A. Configure multi-factor authentication
  • B. Manage compliance baselines for devices
  • C. Notify administrators of potential security issues
  • D. Automate encryption key rotation
Answer: C
Explanation:
While "alerting" is a broad topic, in the context of security:
* Notify administrators of potential security issues (Option B): The alerting system is designed to trigger notifications for security-relevant events. Examples include:
* Failed Login Attempts: Repeated failures which might indicate a brute-force attack.
* Unauthorized Access: Connections from unapproved IPs (if restrictions are set).
* Certificate Expiry: Warning that SSL/TLS certificates are about to expire, which would break secure management connections.
* Encryption Failures: Alerts if a SED drive is unlocked or CloudLink key retrieval fails.

NEW QUESTION # 66
Which action ensures compliance with PowerFlex alerting configurations?
  • A. Configure VLAN tagging for alert traffic
  • B. Assign alerts to fault sets
  • C. Enable snapshot retention policies
  • D. Enable SNMP traps for event monitoring
Answer: D
Explanation:
To ensure that a PowerFlex system complies with enterprise monitoring standards and that administrators are notified of critical failures immediately, integrating with external monitoring tools is essential.
* Enable SNMP traps (Option A): PowerFlex (specifically the Gateway or PowerFlex Manager) can be configured to send Simple Network Management Protocol (SNMP) traps to a central Network Operations Center (NOC) console (like SolarWinds, Nagios, or Dell Secure Connect Gateway). This ensures that if a drive fails or a node goes offline, the event is pushed out immediately rather than waiting for an administrator to log in and check the GUI.
* Why others are incorrect: Alerts are global or device-specific; they are not "assigned to fault sets" (B). Snapshot retention (C) is a data protection setting, not an alerting configuration. VLAN tagging (D) is for network traffic separation, not specifically for "alert compliance."
