NEW QUESTION # 100
An administrator is using SCLI commands to monitor the cluster On which MDM are the commands performed?
- A. Standby
- B. Tie-breaKer
- C. Primary
- D. Secondary
Answer: C
Explanation:
In a PowerFlex system, the SCLI (ScaleIO Command Line Interface) commands are typically performed on the Primary MDM (Metadata Manager). The Primary MDM is responsible for the overall management and operation of the cluster, including configuration changes and monitoring1. It is the authoritative source for metadata and cluster configuration, making it the primary point of interaction for administrative tasks.
The Tie-breaker and Standby MDMs serve as part of the high availability setup. The Tie-breaker MDM is used to avoid split-brain scenarios, and the Standby MDM is a backup that can take over the role of the Primary MDM if it fails. The Secondary MDM works in conjunction with the Primary MDM to manage the cluster but does not serve as the main point for executing SCLI commands.
Therefore, the correct answer is C. Primary, as it is the MDM where SCLI commands are executed for monitoring and managing the PowerFlex cluster.
NEW QUESTION # 101

NEW QUESTION # 102
For what reason would an administrator choose to set the Force Clean SDS option to YES when adding devices to an SDS In the PowerFlex system?
- A. Ensure that the device Is error-free and compatible with PowerFlex
- B. Perform a clean check on the device before adding II
- C. Overwrite existing data on the device during the addition process
- D. Bypass restrictions and proceed with adding The device
Answer: C
Explanation:
The "Force Clean" option in PowerFlex is used when adding devices to an SDS (Storage Data Server) to ensure that any existing data on the device is overwritten during the addition process. This is particularly important when repurposing storage devices that may have been previously used and contain old data or configurations that could interfere with the new PowerFlex deployment1. Setting the Force Clean SDS option to YES will initiate a process that clears any residual data from the device, effectively returning it to a clean state before it is integrated into the PowerFlex system. This step is crucial for maintaining data integrity and preventing potential conflicts that could arise from leftover data on the devices1.
The other options, such as ensuring the device is error-free and compatible with PowerFlex (Option A), performing a clean check on the device before adding it (Option C), or bypassing restrictions to proceed with adding the device (Option B), are not directly related to the purpose of the Force Clean SDS option. While compatibility checks and clean checks are important, they do not involve actively overwriting data on the device.
Therefore, the correct answer is D. Overwrite existing data on the device during the addition process, as it accurately describes the action taken when the Force Clean SDS option is set to YES in the PowerFlex system.
NEW QUESTION # 103
In PowerFlex, what is the purpose of configuring Storage Data Servers (SDS)?
- A. To facilitate user access control
- B. To monitor system health

Answer: C
NEW QUESTION # 104
A user leverages Postman lo send an API request.
What is the default format of the request1?
- A. XML
- B. JSON
- C. JAVA
- D. CSV
Answer: B
Explanation:
When using Postman to send an API request, the default format for the request body is JSON (JavaScript Object Notation). JSON is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is commonly used in API communication because it is language-independent and can be used with most modern programming languages12.
Here's why JSON is the default format:
Human-readable: JSON structures are clear and understandable, making it easy for developers to work with.
Widely supported: JSON is supported by a vast number of APIs and is often the preferred format for RESTful web services.
Efficient: JSON's lightweight nature makes it efficient for network transmission.
While Postman can handle other formats like XML (Option A) and CSV (Option D), and you can write scripts in languages like Java (Option B), JSON remains the default choice for structuring the body of an API request12.

What does FNA enable a customer to do with PowerFlex Manager?
- A. Configure core switches upstream ol the PowerFlex system
- B. Automate configuration ot server-facing ports.
- C. Automate node operating system networking only
- D. Leverage existing network investments and processes
Answer: D
Explanation:
FNA, or Full Network Automation, in the context of PowerFlex Manager, enables customers to leverage their existing network investments and processes. This feature is designed to simplify the deployment and management of PowerFlex systems by automating the configuration of network-related settings and integrating with existing network infrastructures.
Here's how FNA contributes to leveraging existing network investments and processes:
Network Integration: FNA allows PowerFlex Manager to integrate seamlessly with the customer's existing network setup, making use of current investments in network hardware and configurations1.
Automation: It automates the network configuration process for PowerFlex nodes, reducing the need for manual intervention and minimizing the potential for human error2.
Optimization: By automating network configurations, FNA helps optimize network performance and ensures that the PowerFlex system is utilizing the network resources efficiently1.
Simplification: FNA simplifies the management of network settings, making it easier for customers to maintain and scale their PowerFlex environments without having to overhaul their existing network processes1.
The ability to leverage existing network investments and processes is a key advantage of using FNA with PowerFlex Manager, as it allows customers to maintain their current network strategies while benefiting from the automation and optimization that PowerFlex Manager provides1.
NEW QUESTION # 113
What maximum raw capacity can a user expect in a 1U Node while configuring a PowerFlex with an MG pool?
- A. 307.2 TB
- B. 76.8 TB
- C. 153.6 TB
- D. 384TB
Answer: D
Explanation:
The maximum raw capacity that can be expected in a 1U Node while configuring a PowerFlex system with an MG (Multi-Granularity) pool is 38.4 TB. This is based on the typical maximum raw storage capacity available for a 1U node configuration, which is designed to fit within the physical constraints of a 1U rack space while providing a balance of capacity and performance1.
The MG pool in PowerFlex is designed to optimize storage efficiency and performance, and the capacity of a 1U node would be aligned with the specifications that ensure the system's reliability and scalability. The other options listed provide capacities that are generally too high for a single 1U node within the PowerFlex architecture1.
Therefore, the correct answer is
A). 38.4 TB, as it represents the realistic maximum raw capacity for a 1U Node in a PowerFlex system with an MG pool.

Which configuration should be selected''
- A. 36vCPU and 600 GB Disk Space
- B. 42vCPU and 600 GB DisK Space
- C. 36vCPU and 400 GB DisK Space
- D. 42vCPU and 400 GB DisK Space
Answer: A
Explanation:
For setting up PowerFlex Manager with the minimal supported configuration, the customer should select the option with 36vCPU and 600 GB DISK Space. This configuration provides a sufficient amount of resources to support the management operations of PowerFlex Manager while adhering to the minimal requirements.
The selection process for the minimal supported configuration typically involves:
Evaluating Requirements: Understanding the minimal resource requirements for PowerFlex Manager, which includes CPU and disk space.
Matching Specifications: Aligning the available options with the known minimal requirements.
Selecting the Configuration: Choosing the configuration that meets or exceeds the minimal requirements without unnecessary resource allocation.
