Question 1

A systems administrator wants to double the throughput on an existing dual XtremIO X1 10 TB X-Brick cluster. All hosts performing I/O to the cluster are configured and tuned

according to Dell Technologies best practices.

To achieve the performance gain, what should be added?

AA single 10 TB X-Brick Expansion Kit

BA dual 20 TB X-Brick Expansion Kit

CA single 20 TB X-Brick Expansion Kit

DA dual 10 TB X-Brick Expansion Kit

Answer : D

To double the throughput on an existing dual XtremIO X1 10 TB X-Brick cluster, adding a dual 10 TB X-Brick Expansion Kit is recommended.

XtremIO uses a scale-out architecture, and adding a dual X-Brick expansion will increase both storage capacity and performance.

This expansion ensures balanced performance improvement and leverages the best practices configuration already in place for the existing setup.

Question 2

A systems administrator is responsible for the operations of 20 XtremlO X1 clusters; each are using a standalone XMS server. The administrator wants to consolidate management operations to the minimum number of XMS servers as possible.

What is the smallest number of XMS servers that can support the environment?

Answer : B

A single XtremIO Management Server (XMS) can manage up to 8 X-Brick clusters.

For 20 XtremIO X1 clusters, the smallest number of XMS servers required to support the environment is 4.

Consolidating management operations to the minimum number of XMS servers helps in simplifying administration and monitoring tasks.

Question 3

What is the minimum and maximum number of SSDs per DAE for an XtremIO X2-S?

A18 and 36

B36 and 72

C12 and 36

D18 and 72

Answer : C

The XtremIO X2-S system allows for a minimum of 12 SSDs and a maximum of 36 SSDs per Disk Array Enclosure (DAE).

This flexibility in the number of SSDs per DAE allows for scalable storage configurations tailored to varying performance and capacity requirements.

Question 4

Which RESTful API method is used to retrieve an existing XtremIO configuration?

AHTTP RETRIEVE

BHTTP GATHER

CHTTP POST

DHTTP GET

Answer : D

The RESTful API method used to retrieve an existing configuration from a system like XtremIO is the HTTP GET methD. The GET method is used to request data from a specified resource and is one of the most common HTTP methods used in RESTful APIs1.

In the context of the XtremIO REST API, the GET method would be used to access various types of information about the array's configuration. For example, to retrieve details about the volumes configured on an XtremIO array, you would issue a GET request to the appropriate endpoint of the XtremIO REST API2.

The HTTP POST method, on the other hand, is typically used to send data to the server to create or update a resource. The terms HTTP RETRIEVE and HTTP GATHER are not standard RESTful API methods and are not used in the context of the XtremIO REST API or any RESTful API1.

Question 5

A new administrator has the responsibility to register only the applications for protection and configuration of their RPOs. Which privilege level must be assigned to this user in

AppSync?

AData Administrator

BSecurity Administrator

CResource Administrator

DService Plan Administrator

Answer : D

In EMC's AppSync, the Service Plan Administrator role is responsible for managing service plans and RPOs (Recovery Point Objectives). This role includes the ability to register applications for protection and configure their RPOs, which aligns with the responsibilities described for the new administrator1.

The Service Plan Administrator has the privileges needed to assign service levels and manage protection policies within AppSync. This role is crucial for ensuring that applications are protected according to the organization's specific recovery requirements and service level agreements1.

The other roles mentioned, such as Data Administrator, Security Administrator, and Resource Administrator, have different sets of responsibilities and privileges that do not specifically align with the task of registering applications for protection and configuring RPOs within AppSync1. Therefore, the correct privilege level for a new administrator with these responsibilities would be the Service Plan Administrator.

Question 6

A systems administrator wants to add a new XtremlO cluster to their existing XMS that manages multiple clusters. What is a requirement for this activity?

AXMS must manage no more than six clusters

BXMS code version must be compatible with all clusters

CXMS needs to manage clusters on the same subnet

DXMS must manage clusters at the same code

Answer : B

This ensures that the XMS can effectively communicate with and manage each cluster, regardless of their individual configurations or the specific features they are using.

Compatibility is crucial for the XMS to perform its functions across all clusters, which includes tasks such as monitoring, reporting, and executing management operations. If the XMS code version is not compatible with a particular cluster, it may not be able to manage it properly, leading to potential issues with performance, reliability, and data integrity1.

Therefore, before adding a new XtremIO cluster to an existing XMS setup, the systems administrator must verify that the XMS code version is compatible with the firmware version running on the new cluster, as well as the versions on all other clusters currently being managed. This step is a fundamental requirement to ensure seamless management and operation of the XtremIO storage environment1.

Question 7

What is a characteristic of Data at Rest Encryption in XtremIO?

AAuthentication Key PIN is only used to lock SSD encryption

BPrevents unauthorized access in the event of media theft or loss

CData Encryption Key is shared between self-encrypting drives

DEncryption feature can be removed automatically

Answer : B

XtremIO implements Data at Rest Encryption (DARE) to secure data on its SSDs.

This encryption method is designed to prevent unauthorized access to data if the physical media is stolen or lost.

The encryption process involves using a Data Encryption Key (DEK) for each drive, ensuring that data cannot be read without proper authentication.

This feature is crucial for maintaining data integrity and security, especially in scenarios involving sensitive or critical information.
