最新的 Storage Administrator D-XTR-MN-A-24 免費考試真題 (Q10-Q15):

問題 #10
What must be submitted with an RPQ prior to a dispersed XtremlO cluster installation?

A. Cabling kits and X-Brick component location diagram
B. Wiring diagram and X-Brick component location diagram
C. Cabling kits and list of allowed deviations from the RPQ
D. Wiring diagram and list of cables needed for the cluster

答案：B

解題說明：
When submitting a Request for Product Qualification (RPQ) prior to a dispersed XtremIO cluster installation, it is necessary to include a wiring diagram and an X-Brick component location diagram. The wiring diagram provides a detailed representation of the electrical connections between the components, while the X-Brick component location diagram shows the physical placement of the X-Brick components within the installation environment. These documents are essential for planning the installation to ensure that all components are correctly positioned and connected for optimal performance and serviceability1.
The process for preparing these documents typically involves:
Creating a detailed wiring diagram that outlines all the necessary connections between the X-Brick components and other infrastructure elements.
Developing an X-Brick component location diagram that illustrates where each component will be physically located in the data center.
Reviewing the diagrams to ensure they meet the technical requirements and specifications for a dispersed XtremIO cluster installation.
Submitting the diagrams along with the RPQ for approval before proceeding with the installation.
These steps are crucial for a successful installation and are outlined in the Official Dell XtremIO Maintenance Achievement document1.

問題 #11
On XtremlO X1, what is required before the cluster will start?

A. BBUs must be charged to at least 70%
B. BBUs must be charged to at least 50%
C. At least one BBU has to be online
D. End of Life BBUs must be replaced

答案：A

解題說明：
Before an XtremIO X1 cluster can start, it is required that the Battery Backup Units (BBUs) are charged to at least 70%. This ensures that there is sufficient power reserve to maintain data integrity and allow for safe shutdown procedures in case of an unexpected power loss. The BBUs provide power to the Storage Processors and other critical components during an outage, allowing them to complete any in-progress operations and commit data to SSDs1.
The startup process checks the BBU charge level and will only proceed if the minimum charge requirement is met. This is a safety feature designed to protect the system and the data it holds. If the BBUs are not adequately charged, the system will not start, preventing potential data loss or corruption that could occur if the system were to lose power without the ability to properly shut down1.

問題 #12
A multi X-Brick XtremlO X1 cluster is being installed. How many BBU connections, and of which type, are required per X-Brick?

A. 1 BBU providing protective power to the Storage Controllers
2 BBU COM ports; one connected to each Storage Controller
B. 1 BBU providing protective power to the bottom Storage Controller
2 BBU COM ports; one connected to each Storage Controller
C. 2 BBUs providing protective power to X-Brick 1 and 2 Storage Controllers only
4 BBU COM ports connected to each Storage Controller
D. 2 BBUs providing protective power to the Storage Controllers
1 BBU COM port connected to the bottom Storage Controller

答案：A

解題說明：
For a multi X-Brick XtremIO X1 cluster, each X-Brick requires one Battery Backup Unit (BBU) that provides protective power to both Storage Controllers within the X-Brick. Additionally, there are two BBU COM (communication) ports required, with one connected to each Storage Controller. This configuration ensures that in the event of a power failure, the BBU can maintain power to the Storage Controllers, allowing them to safely shut down and protect data integrity1.
The installation process would typically involve:
Installing the BBU in the designated slot within the X-Brick.
Connecting the BBU power cable to the power supply of both Storage Controllers.
Connecting a BBU COM port to each Storage Controller for communication and monitoring purposes.
This setup is crucial for maintaining the high availability and data protection standards that XtremIO systems are known for1.

問題 #13
What is the correct sequence of steps to power up an XtremlO X1 cluster after an emergency shutdown?

答案：

解題說明：

1 - Determine the cause of the shutdown
2 - Power up the Battery Backup Units
3 - Power up the XMS
4 - Power up the Storage Controllers
5 - Start the cluster

問題 #14
What is the impact of a serial cable failure in a multi X-Brick XtremIO X1 cluster?

A. Failure of more than half of the COM cables forces the cluster into a degraded mode
B. Failure of one serial cable makes the BBU not visible to the cluster's environment monitoring
C. Failure of more than half of the BBU COM cables results in a loss of service
D. Failure of one COM cable results in a loss of service

答案：A

解題說明：
In a multi X-Brick XtremIO X1 cluster, the failure of more than half of the COM (communication) cables forces the cluster into a degraded mode. This degraded mode is a protective measure to ensure that the cluster can continue operating with reduced performance and redundancy until the issues with the COM cables are resolved.
