Dell EMC Dell XtremIO Deploy Achievement Exam Practice Test

Answer : D

The RESTful API method used to retrieve an existing configuration from an XtremIO system is the HTTP GET methD. This is a standard method used in RESTful APIs for retrieving resources. In the context of XtremIO, the GET method would be used to call endpoints that return information about the system's configuration. For example, a GET request to /api/json/v2/types/clusters would retrieve information about the clusters1. The Official Dell XtremIO Deploy Achievement document will contain specific details on the API calls and should be referred to for the most accurate instructions.

Answer : A

In the event of a power failure, the XtremIO X2 system's NVRAM (Non-Volatile Random Access Memory) card will initiate the discharging of the SuperCapacitor (SuperCap). The SuperCap is designed to provide enough power to the NVRAM card to allow it to write any data in transit to a non-volatile storage medium, ensuring data integrity and preventing loss1. This process is a critical part of the XtremIO X2's data protection mechanism during unexpected power interruptions.

Answer : D

The image provided shows the back panel of a network device, with ports labeled 'a', 'b', 'c', and 'd'. The ports 'b' and 'd' are indicated to be used for FC2 (Fibre Channel 2) and iSCSI 1 connections, respectively. This is inferred from the color coding and labeling typical in network hardware, which helps distinguish between different types of connections. While the Official Dell XtremIO Deploy Achievement documents would provide definitive information, standard network design practices suggest that the correct answer is D. b and d, for FC2 and iSCSI 1 connections respectively.

Answer : C

According to the Dell Technologies community forum and support articles, the show-clusters-info command in the XtremIO Management Server (XMS) CLI provides information about the clusters. For a healthy XtremIO cluster, the state should be displayed as active and connected1. This indicates that the cluster is operational (active) and has a stable connection with the necessary components and network (connected). It's important to ensure that the cluster state does not show as disconnected, which could imply issues with network connectivity or other problems affecting the cluster's operation2.

Answer : B

The Dell XtremIO Deploy Achievement documents specify different numbers for the maximum volumes in various contexts. However, for the XtremIO Consistency Group, the supported and QA certified number of volumes is 512. This is based on the authoritative information provided in the official release notes and support documents from Dell. It's important to note that while there may be higher numbers mentioned in some technical documents or API responses, such as 60000 or 32000, these are either not recommended or pertain to different aspects of the XtremIO system, not specifically to the Consistency Group1.

Answer : D

When powering up an XtremIO X2 multi X-Brick cluster, both the Disk Array Enclosures (DAEs) and the Storage Controllers will automatically power up once the rack Power Distribution Units (PDUs) are turned on. This process ensures that the essential components for storage and data management are operational immediately, facilitating a seamless startup of the storage environment. The DAEs contain the SSDs for data storage, while the Storage Controllers manage the data operations, ensuring high performance and reliability.

Dell EMC XtremIO X2 documentation explains that upon powering the PDUs, the DAEs and Storage Controllers automatically power up as part of the system's startup process

Answer : B

When configuring a VMware Horizon environment with 1000 linked clones connected to an XtremIO storage system, the minimum number of datastores required to support this configuration, based on best practices, is four. This recommendation ensures optimal performance and manageability while avoiding overcommitment of resources.

The process for determining the minimum number of datastores involves:

Assessing Performance Needs: Evaluate the performance requirements of the linked clones, considering factors such as IOPS (Input/Output Operations Per Second) and throughput.

Understanding XtremIO Capabilities: Recognize that XtremIO's all-flash array provides high performance and low latency, which can support a large number of clones per datastore.

Considering VMware Best Practices: VMware's best practices suggest balancing the number of clones across multiple datastores to optimize performance and manageability1.

Calculating Datastore Requirements: For 1000 linked clones, dividing them across four datastores allows for sufficient distribution without exceeding the capabilities of the XtremIO system.

Implementing the Configuration: Create and configure the four datastores within the VMware Horizon environment, ensuring they are properly connected and recognized by the XtremIO storage system.

Monitoring and Adjusting: After implementation, continuously monitor the performance and capacity of the datastores, making adjustments as necessary to maintain optimal operation.

It's important to note that while four is the minimum recommended number based on best practices, the actual number may vary depending on specific environmental factors and requirements. Always refer to the latest official documentation and consult with Dell support for tailored advice.
