Dell EMC Dell XtremIO Deploy Achievement Exam Practice Test

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 : C

When configuring Linux hosts to support XtremIO storage, it is recommended to set the LUN queue depth to 64. This setting helps to optimize the performance of the host when communicating with the XtremIO storage system.

Access Host Configuration: Log into the Linux host that will be connected to the XtremIO storage.

Modify HBA Parameters: Locate the HBA (Host Bus Adapter) parameters within the host's configuration files.

Set Queue Depth: Adjust the queue depth parameter for the HBA to 64. This can typically be done by editing the options.conf file or similar, depending on the HBA driver in use.

Apply Changes: Save the changes and reload the HBA driver or reboot the host to apply the new configuration.

Verify Configuration: Confirm that the new queue depth setting is active and functioning as expected.

Answer : D

When connecting a VMware cluster to an XtremIO array using QLogic Fibre Channel Host Bus Adapters (HBAs), the recommended value for the Execution Throttle is typically set to 4096. This setting controls the maximum number of outstanding I/O operations that can be sent to a Fibre Channel port.

Here's how to apply this setting:

Access HBA Settings: Log into the VMware host and access the settings for the QLogic Fibre Channel HBA.

Locate Execution Throttle: Find the parameter for the Execution Throttle within the HBA settings.

Set Value: Change the value of the Execution Throttle to 4096. This is the recommended setting to balance performance and resource utilization.

Save and Apply: Save the changes and apply them to the HBA. A reboot of the host may be required for the changes to take effect.

Verify Configuration: After the host is back online, verify that the new Execution Throttle setting is active and functioning as expected.

Monitor Performance: Monitor the performance of the host and the storage array to ensure that there are no adverse effects from the change.

Consult Official Documentation: For the most accurate and detailed instructions, always refer to the official Dell XtremIO Deploy Achievement document1. This document will provide the authoritative guidance on HBA settings and best practices for connecting to an XtremIO array.

It's important to note that while the value of 4096 is a common recommendation, the optimal setting may vary based on the specific environment and workload. Therefore, it's essential to refer to the latest Dell XtremIO documentation and possibly consult with Dell support for the most current and tailored advice.

Answer : D

The maximum number of 10 TB X-Bricks that can be configured in an XtremIO X1 cluster is four. This information is based on the data available up to my last update in 2021 and the search results obtained from the web.

Understanding X-Bricks: An X-Brick is the storage building block of an XtremIO system. Each X-Brick contains SSDs and provides a certain amount of storage capacity.

Cluster Configuration: The XtremIO X1 cluster is designed to scale out by adding additional X-Bricks to increase performance and capacity.

Maximum Number: At launch, the XtremIO platform supported up to 4 X-Bricks1. This allowed for expansion within a single cluster by adding more X-Bricks as needed.

Reference to Official Documentation: For the most accurate and up-to-date information, it is essential to refer to the latest official Dell XtremIO Deploy Achievement documents. These documents provide detailed specifications, including the maximum number of X-Bricks supported in different configurations.

Consulting Dell Support: If there have been updates or changes after my last knowledge update in 2021, consulting Dell support or the latest technical documentation would provide the current specifications.

In summary, based on the information available, the maximum number of 10 TB X-Bricks that can be configured in an XtremIO X1 cluster is four. However, always refer to the latest official documentation or Dell support for the most current information.
