NEW QUESTION # 10
What is the minimum number of nodes required to create a production PowerFlex Management Platform Cluster?
Answer: A
Explanation:
The minimum number of nodes required to create a production PowerFlex Management Platform Cluster is 3, ensuring fault tolerance and redundancy.
* Reason for 3 Nodes (Option D):
* A minimum of three nodes is required to ensure proper cluster functionality, including quorum for the Metadata Manager (MDM) roles.
* This configuration supports high availability and fault tolerance, ensuring the cluster remains operational even if one node fails.
* Why Not the Other Options?
* Option A: 9: While additional nodes can be added to enhance capacity and redundancy, nine nodes are not the minimum requirement.
* Option B: 1: A single node does not provide redundancy or failover capabilities, which are critical for production environments.
* Option C: 5: While five nodes increase capacity and resilience, the minimum requirement is only three nodes.

NEW QUESTION # 11
PowerFlex is being deployed on the Management Controller. Three MDMs have been added to the cluster.
Which step should you take next?
Answer: A
Explanation:
After adding three Metadata Managers (MDMs) to the cluster, the next critical step is to add a tie breaker MDM (Option B).
* Why Add a Tie Breaker MDM?
* A tie breaker MDM ensures cluster quorum in case of a split-brain scenario or if there is a failure of the primary or secondary MDMs.
* It maintains the consistency and availability of the cluster, ensuring data integrity during failover situations.
* Why Not the Other Options?
* Option A: Move on to creating protection domains: Protection domains can only be created after the cluster setup, including tie-breaker addition, is complete.
* Option C: Convert the cluster to a multi-node cluster: The cluster is already in a multi-node configuration after adding three MDMs.
* Option D: Add a second MDM to the cluster: This step has already been completed with three MDMs added, so it is unnecessary at this stage.

NEW QUESTION # 12
Which two steps must be completed to finish configuring the Management Controller, once the PowerFlex has been deployed? (Select 2)
Answer: B,D
Explanation:
After deploying PowerFlex, additional steps are necessary to finalize the Management Controller configuration:
* Enable VMware vSphere HA and DRS (Option A):
* vSphere High Availability (HA) ensures VMs are restarted on another host in case of host failure.
* Distributed Resource Scheduler (DRS) automatically balances workloads across the cluster to optimize performance and resource usage.
* Enabling these features is critical for ensuring resilience and load balancing in the PowerFlex environment.
* Reconfigure MDM Roles (Option E):
* The Metadata Manager (MDM) roles must be reconfigured to align with the deployed topology.
* This involves setting the Primary, Secondary, and Tie-Breaker roles for fault tolerance and system consistency.
Why Not the Other Options?
* Option B: Configure a File Services node: This is applicable if deploying file services, but it is not a mandatory step for the Management Controller.
* Option C: Set up a NAS server: Similar to Option B, this is not a general requirement for configuring the Management Controller unless file services are explicitly needed.
* Option D: Delete vSwitch0: While network configuration may require adjustments, deleting vSwitch0 is not a standard step and could disrupt connectivity.

NEW QUESTION # 13
Which four prerequisites must be met before deploying PowerFlex on the Management Controller?
(Select 4)
Answer: A,C,D,F
Explanation:
Before deploying PowerFlex on the Management Controller, there are essential prerequisites to ensure a smooth and functional deployment:
* Deploy VMware vCenter (Option B):
* VMware vCenter is required to manage the ESXi hosts and VMs in the PowerFlex cluster. This ensures proper virtualization management and cluster configuration.
* vCenter also supports features like High Availability (HA) and Distributed Resource Scheduler (DRS), which are essential for PowerFlex operations.
* Install and Configure ESXi on the Management Controller (Option C):
* The Management Controller must have a functioning ESXi hypervisor to host the PowerFlex management components and virtual machines.
* ESXi installation ensures the virtualization layer is ready to manage PowerFlex VMs.
* Deploy and Configure the Storage VMs (Option D):
* PowerFlex storage nodes and VMs must be properly configured to enable storage pooling and service delivery.
* This includes ensuring the SDS (Storage Data Server) and MDM (Meta Data Manager) roles are assigned to VMs.
* Configure the Switch Ports (Option E):
* Network connectivity must be established by configuring switch ports to support proper communication between components.
* This step includes setting VLANs, MTU settings (jumbo frames), and ensuring link aggregation configurations are in place for redundancy and performance.
Why Not the Other Options?
* Option A: Set up hardware affinity: While hardware affinity is important for VM placement, it is not a prerequisite for deploying PowerFlex.
* Option F: Configure VM HA and DRS: These are typically configured after deployment and are not prerequisites for the initial setup.
