Dell EMC Dell XtremIO Design Achievement D-XTR-DS-A-24 Exam Questions

Answer : A

In RESTful API design, the HTTP method used to create new resources or objects is POST. This method is utilized when the client needs to send data to the server to create a new entity. For example, when integrating with an SQL application and creating new objects on an XtremIO cluster, using a POST request with the appropriate payload will instruct the server to create the new resources as specified1.

A well-designed REST API implements CRUD operations using different HTTP methods, with POST being the method for Create operations1.

The Dell Technologies Developer Portal provides resources and documentation on REST APIs, including the methods used for various operations2.

Answer : D

To maximize the connectivity between Storage Controllers and Fibre Channel switches, all available ports should be utilized. This ensures redundancy and maximizes throughput. The exhibit provided shows a Storage Controller with four ports labeled 1, 2, 3, and 4. Without specific design documents, the general best practice is to use all available ports for such connections, assuming the ports are configured for Fibre Channel traffic and the infrastructure supports it.

General best practices for Fibre Channel connectivity and port usage are discussed in various Dell EMC documents, such as the ''Introduction to XtremIO X2 Storage Array'' and ''Configuring Fibre Channel Storage Arrays'' documents12.

Specific port configurations and their usage would be detailed in the Dell XtremIO Design documents, which would provide definitive guidance on which ports to use for connecting to Fibre Channel switches.

Answer : A

Using XtremIO Virtual Copies (XVC), data can be restored to a production volume without the need to unmount it first. This feature allows for greater flexibility and efficiency in managing data restoration processes. The XVC technology enables the creation of space-efficient snapshots and copies of volumes that can be used for various purposes, including data restoration1.

The XtremIO Snapshots (XVC) Inquiries on Dell Technologies Community Forum provides insights into the capabilities of XVC, including the ability to restore data without unmounting the production volume1.

Additional information on the functionality and usage of XVC can be found in the XtremIO Host Configuration Guide2.

Answer : D

The Dell EMC Power Calculator is a tool designed to help IT professionals plan and tune their computer and infrastructure equipment for maximum efficiency. The outputs generated by the Dell EMC Power Calculator include:

Power Consumption: This is the total amount of electrical power used by the equipment.

Heat Dissipation: This refers to the amount of heat generated by the equipment that needs to be managed within the data center environment.

Annualized Energy Costs: This is an estimate of the yearly energy costs associated with operating the equipment.

Footprint: This refers to the physical space required for the equipment within the data center.

These outputs are crucial for data center planning, as they help in understanding the energy efficiency, cooling requirements, operational costs, and space utilization of the IT infrastructure1.

The Dell Technologies Enterprise Infrastructure Planning Tool (EIPT) provides detailed information on the configuration flexibility and environmental inputs that can help right-size an IT environment, which includes the Dell EMC Power Calculator1.

Answer : D

When Global Technical Support requests a connection to the TECH port of a physical XtremIO X2 XMS, the service machine should be connected to the MGMT ETH0 port on the server. This port is typically used for management purposes and allows for the necessary communication between the service machine and the XtremIO X2 XMS for technical operations and support.

The Dell EMC support document outlines issues related to the management network configuration failure and mentions the physical XMS management port, which is relevant to the TECH port connection1.

Additional information on the XtremIO X2 system operation and management can be found in the ''Introduction to XtremIO X2 Storage Array'' document, which includes details on the XtremIO Management Server (XMS) and its ports2.

Answer : A

For Microsoft Windows servers running MPIO, the optimal path selection policy when connected to an XtremIO cluster is Round Robin. This policy allows for load balancing across all available paths by distributing I/O evenly, which can lead to better performance and utilization of the storage resources. The Round Robin policy ensures that no single path is overloaded with I/O requests, which helps in maintaining consistent performance levels1.

The Dell EMC SC Series: Microsoft Multipath IO Best Practices document provides insights into the recommended path selection policies for optimal performance2.

Additional information on MPIO and path selection policies can be found in the Dell EMC knowledge base articles1.

Answer : A

The recommended execution throttle setting for Qlogic adapters, when used with Windows, Linux, and VMware, is typically set to the maximum value to allow for the greatest throughput and performance. The execution throttle setting determines the maximum number of outstanding I/O operations that can be queued to the storage controller. For Qlogic Fibre Channel adapters, especially when the HBA speed is 8GBs or over, the execution throttle can be set to 65,5351. This high setting is used to ensure that the storage array can handle a large number of concurrent I/O requests, which is beneficial in environments with high-performance requirements.
