Question No : 1
Which four pre-requisites must be met before deploying PowerFlex on the Management Controller? (Select 4)

A.Deploy VMware vCenter.
B.Deploy and configure the storage VMs
C.Configure VM HA and DR
D.Set up hardware affinity.
E.Configure the switch ports.
F.Install and configure ESXi on the management controller.

正解:

Question No : 2
See the image:

PowerFlex is being deployed on the Management Controller. Three MDMs have been added to the cluster.
Which step should you take next?

A.Add a second MDM to the cluster.
B.Convert the cluster to a multi node cluster.
C.Move on to creating protection domains.
D.Add a tie breaker MDM to the cluster.

正解:

Question No : 3
Where are DNS server records configured, when deploying the PowerFlex Management Controller VMs?

A.hosts
B.Config
C.ifcfg-eth<##>
D.Routes

正解:

Question No : 4
When deploying a new PowerFlex cluster, what is the most logical order to deploy the following components?

A.SDC → SDS → MDM → Manager
B.MDM → SDS → SDC → Manager
C.Manager → MDM → SDS → SDC
D.MDM → Manager → SDS → SDC

正解:
Explanation:
MDM provides core metadata services and is the first step in system construction; Manager is used to deploy and configure components such as SDS and SDC.

Question No : 5
You are configuring a storage network for PowerFlex.
Which of the following network configurations best align with best practices for a production environment? (Multiple choice)

A.Set Jumbo Frame and MTU value to 9000
B.Use a dedicated storage VLAN to isolate from the production network
C.Enable LACP and ECMP on the storage traffic path
D.Place management and data traffic on the same physical NIC to save port resources

正解:
Explanation:
In high-performance environments, large frame transmission should be used, and independent VLANs should be used to ensure isolation; LACP and ECMP should be used to improve link reliability and bandwidth. D will affect performance and isolation.

Question No : 6
After deploying PowerFlex, you find that only some of the SDS nodes in the created storage pool are successfully added, and the system prompts that some disks are unavailable.
Which of the following is most likely the reason?

A.No trust relationship is established between the SDS node and MDM
B.These disks are not properly set up in JBOD mode or do not have HBA pass-through
C.SDC is not connected to SDS
D.SDS nodes are running different versions of PowerFlex software

正解:
Explanation:
Solution: If the disk is not exposed in JBOD mode or does not support pass-through, it cannot be added to the PowerFlex storage pool.

Question No : 7
A customer wants to centrally manage storage resources and deploy computing resources on heterogeneous virtualization platforms (including VMware and KVM).
Which of the following deployment modes is most suitable?

A.Hyperconverged
B.Two-layer deployment
C.Traditional SAN model
D.Public cloud backup mode

正解:
Explanation:
Two-tier deployment decouples computing and storage, allowing storage resources to be centrally managed while serving multiple different virtualization platforms.

Question No : 8
In a PowerFlex environment, which of the following situations would most likely cause the SDC to lose access to storage volumes?

A.The MDM Primary node fails and the Secondary node does not take over the metadata management role
B.The SDS node has a firewall enabled, blocking communication on port 7072
C.The network MTU is inconsistent between SDC and SDS, but MDM is accessible
D.All SDCs are operating normally but are not registered with the management controller

正解:
Explanation:
Port 7072 is the key port for communication between SDS and SDC. Firewall blocking will result in access interruption. Although MDM failure will affect management functions, it will not immediately interrupt the established data path.

Question No : 9
After completing the PowerFlex installation, which of the following configuration steps are required to put the system into production use? (Multiple choice)

A.Configuring storage pools
B.Create and assign volumes
C.Set up a shared folder
D.Configure performance and data protection strategies

正解:

Question No : 10
Once installed, how should you verify connectivity of the PowerFlex cluster components?

A.Check the BIOS log
B.Use ping or telnet to test component IP connectivity
C.View the file system mount point
D.Check for driver updates

正解:

Question No : 11
What types of file system shares do PowerFlex File Nodes support? (Multiple choice)

A.NFS
B.CIFS/SMB
C.iSCSI
D.FTP

正解:

Question No : 12
What is the purpose of deploying PowerFlex File Node?

A.Implement automatic snapshot function
B.Add file-level storage services (such as NFS/SMB)
C.As a management node
D.Enable multipath IO

正解:

Question No : 13
Which of the following is responsible for the connection between the client and the storage?

A.SDS
B.MDM
C.SDC
D.GUI

正解:

Question No : 14
Which of the following statements is true about the PowerFlex Manager and PowerFlex Management Controller?

A.They have the same function, only the names are different
B.Manager is used for deployment and configuration, and Controller is responsible for performance monitoring
C.Manager is a tool for comprehensive management and automated deployment, while Controller focuses on lifecycle operations
D.Controller is a hardware plug-in, Manager is a software service

正解:

Question No : 15
What are the key features of PowerFlex Management Controller 2.0?

A.Provide centralized log management
B.Simplify lifecycle management
C.Monitor virtual machine performance
D.As iSCSI storage target service
