Minimum of three-node MDM cluster

Minimum of three SDS nodes

NO.36 An administrator is creating an NFS export on a PowerFlex system with existing File shares. They are unable to select the NFS option.
What is the cause of the issue?

The NAS server is not joined to Active Directory.

The NAS server does not have NFS enabled.

The file system has quotas that are applied.

The file system is out of available capacity.

NO.37 Which PowerFlex component provides the information that application servers require to connect to the cluster’s virtualized storage?

MDM

SDC

SDR

SDS

The PowerFlex component that provides the information application servers require to connect to the cluster’s virtualized storage is the Storage Data Client (SDC). The SDC is installed on application servers and is responsible for translating standard block I/O requests from the server’s operating system into network I/O requests that can be understood and processed by the PowerFlex storage cluster.
Here’s a detailed explanation:
SDC Role: The SDC acts as the interface between the application servers and the PowerFlex storage system. It allows servers to access the virtualized storage as if it were local to the server1.
Connection Process: When an application server needs to connect to the PowerFlex cluster, the SDC communicates with the Meta Data Manager (MDM) to understand the layout of the storage and then interacts with the Storage Data Server (SDS) to perform I/O operations1.
Virtualized Storage Access: Through the SDC, application servers can perform read and write operations on the virtualized storage volumes provided by the PowerFlex cluster, ensuring seamless integration with the existing applications and services1.
The SDC is a critical component in the PowerFlex architecture, enabling the connection and communication between application servers and the PowerFlex storage cluster, thus facilitating the use of virtualized storage resources1.

NO.38 A user must make data available over the SMB protocol.
Which software component must be used?

FSN

SDT

MDM

SDS

NO.39 What are the deployment models supported by PowerFlex?

Standalone only

Hyperconverged only

Both standalone and hyperconverged

Distributed only

NO.40 What role does PowerFlex Manager play in the architecture?

Storage provisioning only

Network management only

Centralized management and orchestration

Compute resource allocation only

NO.41 What is the amount of spare space that PowerFlex Sizer assumes?

10%

11%

12%

15%

NO.42 Which authentication protocols are commonly used for secure integration of PowerFlex? (Select all that apply)

LDAP (Lightweight Directory Access Protocol)

Kerberos

RADIUS (Remote Authentication Dial-In User Service)

SNMP (Simple Network Management Protocol)

NO.43 In PowerFlex, what is the primary purpose of Protection Domains?

To provide network security

To manage storage capacity

To group related volumes

To ensure data durability and availability

NO.44 A customer has ordered five servers with NVDlMMs Each server has 5 x 3 84 TB SAS and 5 x 3 84 T8 NVMe disks They want to ensure that the highest capacity ot storage is available to the system Which design provides the required storage pool structure”

One Storage Pool and one Acceleration Pool

One Acceleration Pool only

One Storage Pool only

One Acceleration Pool and two Storage Pools

To maximize the storage capacity available to the system while utilizing NVDIMMs, SAS, and NVMe disks, the design should include both a Storage Pool and an Acceleration Pool. The Storage Pool will be used for the bulk storage provided by the SAS disks, while the Acceleration Pool, leveraging the high-speed NVMe disks, will be used to accelerate the performance of the storage system.
The use of NVDIMMs in PowerFlex is associated with enabling fine-granularity storage pools that provide compression, which is beneficial for space efficiency, especially with heavy snapshot use1. This configuration allows for the creation of a storage pool that can take advantage of the NVDIMMs’ capabilities for compression and the high capacity of the SAS disks, while the NVMe disks in the Acceleration Pool provide high-performance storage for more demanding workloads.
Therefore, the correct answer is A. One Storage Pool and one Acceleration Pool, as this design will provide the highest capacity of storage available to the system while also ensuring optimal performance through the use of NVMe disks in the Acceleration Pool.

NO.45 An administrator wants to delete a secure snapshot that was created 30 days ago and has a 60-day expiration period The snapshot was created by a snapshot policy and lock is enabled.
How can the administrator delete the snapshot?

Use the Dual Signature Policy agreement with Dell

Disable Uie snapshot policy lock on the snapshot.

Change the snapshot expiration period to 30 days

Secure snapshots in PowerFlex are controlled by policies that define their retention and expiration periods. If a snapshot has a lock enabled, it cannot be deleted until the lock is disabled. The lock is a security feature that prevents accidental or unauthorized deletion of the snapshot before its intended retention period1.
To delete a secure snapshot that is still within its expiration period but needs to be removed, the administrator must first disable the snapshot policy lock.
Here are the general steps to do so:
Access PowerFlex Manager.
Navigate to the Snapshots section.
Locate the specific snapshot that needs to be deleted.
Disable the lock on the snapshot policy associated with the snapshot.
Once the lock is disabled, the snapshot can be deleted manually.
Changing the snapshot expiration period to 30 days (Option C) would not affect the ability to delete the snapshot if the lock is still enabled. The Dual Signature Policy agreement with Dell (Option A) is not a standard procedure for deleting snapshots within PowerFlex and is not related to the administrative controls of snapshot policies.
Therefore, the correct answer is B. Disable the snapshot policy lock on the snapshot, as this action will allow the administrator to delete the snapshot before the expiration period, provided that the snapshot is no longer needed and can be safely removed from the system1.
