EMC Dell XtremIO Design Achievement Sample Questions (Q18-Q23):

NEW QUESTION # 18
What can be demonstrated with the XMS Simulator?

  • A. Deploying XMS
  • B. Configuring connectemc
  • C. Initializing cluster
  • D. Creating volumes

Answer: D

Explanation:
The XtremIO XMS Simulator can be used for various purposes, including demos, product training, comparing XMS/XtremIO version release functionality, testing scripts against XtremIO's RESTful API, and XtremIO development, testing, and simulation1. Among the options provided, creating volumes is a task that can be demonstrated with the XMS Simulator.This is because the simulator allows users to interact with a simulated XtremIO environment, which includes managing and operating volumes as part of the overall management simulation1.


NEW QUESTION # 19
What is an example of a Decision Support Systems (DSS) workload?

  • A. Order Entry applications
  • B. Data Warehouse
  • C. Online banking applications
  • D. Airline reservation systems

Answer: B

Explanation:
Explore
A Decision Support System (DSS) is a computer-based tool designed to aid individuals and organizations in making informed decisions. It integrates data, models, and analytical tools to solve complex problems and support strategic planning.A DSS is particularly effective in handling large volumes of data and applying sophisticated algorithms to generate insights that guide effective choices1.
A Data Warehouse is an example of a DSS workload because it is a centralized repository for storing large amounts of data from multiple sources.Its primary purpose is to facilitate reporting and analysis1. Data Warehouses are designed to perform queries and analysis on historical data and are an integral part of business intelligence that supports decision-making processes.
References:
* A comprehensive explanation of what constitutes a DSS and its applications can be found in various resources, including those that define a Data Warehouse as a key component of DSS1.
* The "Introduction to XtremIO X2 Storage Array" document by Dell Technologies provides insights into the system features that support DSS workloads like Data Warehouses2.


NEW QUESTION # 20
Which SCSI instructions are used to build a bitmap of the changes between the first snapshot and subsequent snapshots when RecoverPoint is used with XtremIO?

  • A. SCSI TRANSFER
  • B. SCSI DIFF
  • C. SCSI DELTA
  • D. SCSI UPDATE

Answer: B

Explanation:
TheSCSI DIFFinstruction is used to build a bitmap of the changes between the first snapshot and subsequent snapshots when RecoverPoint is used with XtremIO1.
The DIFF protocol is a vendor-specific SCSI command which RecoverPoint uses to query XtremIO in order to obtain a bitmap of changes between two snapshot sets1.RecoverPoint uses the output of the DIFF command to read the actual data and transfer it to the target side1.
The other options provided are not typically used for this purpose:
* SCSI DELTAis not a recognized SCSI command2.
* SCSI TRANSFERis not a recognized SCSI command3.
* SCSI UPDATEis not a recognized SCSI command4.
Therefore, the verified answer is A.SCSI DIFF, as it is the SCSI instruction used to build a bitmap of the changes between the first snapshot and subsequent snapshots when RecoverPoint is used with XtremIO1.


NEW QUESTION # 21
A customer is using a third party RESTful API client to create a series of new objects on an XtremlO cluster for use with their SQL application. Which HTTP method should be used to create the objects needed for integration with the SQL application?

  • A. GET
  • B. POST
  • C. DELETE
  • D. PUT

Answer: B

Explanation:
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.
References:
* 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.


NEW QUESTION # 22
Which disk format should be used for ESXi Disks provisioned by XtremIO?

  • A. Eager zeroed thick
  • B. Thin
  • C. Zeroed thick
  • D. Thick

Answer: A

Explanation:
For ESXi disks provisioned by XtremIO, the recommended disk format is 'Eager Zeroed Thick'. This format is preferred because it allocates all the space required for the disk at the time of creation and zeroes out any previous data on the physical media. Compared to other formats, 'Eager Zeroed Thick' provides better performance due to the pre-zeroing of the disk space, which helps in avoiding any latency that might occur during write operations as there is no need to zero out blocks before writing new data.
References:
* While the specific Dell XtremIO Design document was not available, the general best practice for high-performance storage solutions like XtremIO is to use 'Eager Zeroed Thick' provisioning for VMs running on VMware ESXi to ensure optimal performance1.
* Additional information on disk provisioning and best practices can be found in VMware's official documentation and Dell EMC's storage configuration guides2.
