EMC Dell XtremIO Maintenance Achievement Sample Questions (Q40-Q45):

NEW QUESTION # 40
What is indicated when the XtremIO X2 NVRAM status LED is flashing red at one second intervals?

A. Backup is in progress
B. Uncorrectable error
C. Firmware or driver is loaded
D. Restore is in progress

Answer: B

Explanation:
When the NVRAM status LED on an XtremIO X2 is flashing red at one-second intervals, it indicates an uncorrectable error. This is a critical status that typically signifies a hardware malfunction or failure within the NVRAM module, which requires immediate attention. NVRAM, or Non-Volatile Random Access Memory, is crucial for retaining data integrity during power losses or system crashes1.
The steps to address this issue usually involve:
Investigating the system logs to identify the specific nature of the error.
Contacting Dell EMC support for guidance on diagnosing and resolving the issue.
Following the recommended procedures for troubleshooting or replacing the affected NVRAM module, as per the support team's instructions.
It is important to resolve such errors promptly to prevent potential data loss and to maintain the overall health and performance of the storage system1.

NEW QUESTION # 41
When preparing for a single-to-dual online cluster expansion, which power cables are pre-staged by being connected to PDU-B only?

A. X2-DAE-PSU-R and X2-DAE-PSU-L
B. X2-SC1-PSU-R and X2-SC2-PSU-R
C. IBSW-PSU-L and IBSW-PSU-R
D. X1-SC1-PSU-L and X1-SC2-PSU-L

Answer: B

Explanation:
In preparation for a single-to-dual online cluster expansion, the power cables that are pre-staged by being connected to Power Distribution Unit B (PDU-B) only are for the right-side Power Supply Units (PSUs) of the Storage Controllers (SCs). Specifically, these would be the power cables for X2-SC1-PSU-R and X2-SC2-PSU-R. This configuration ensures that there is a balanced power distribution across the PDUs and that the new cluster components will have power connectivity once they are physically installed1.
The process typically involves:
Identifying the correct power cables for the SCs' PSUs.
Connecting these cables to the designated ports on PDU-B.
Ensuring that the cables are properly managed and labeled for easy identification during the expansion process.
This procedure is part of the standard practices for expanding an XtremIO cluster, as detailed in the Official Dell XtremIO Maintenance Achievement document1.

NEW QUESTION # 42
What is the impact of a serial cable failure in a multi X-Brick XtremIO X1 cluster?

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

Answer: B

Explanation:
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.

NEW QUESTION # 43
On an XtremlO X2-S, which ports are used on the InfiniBand switches for an ISL connection?

A. 17 and 18
B. 35 and 36
C. 1 and 2
D. 11 and 12

Answer: B

Explanation:
For an XtremIO X2-S, the ports used on the InfiniBand switches for an Inter-Switch Link (ISL) connection are typically high-numbered ports, which are usually at the end of the port range on the switch. While the specific port numbers can vary depending on the switch model and configuration, ports 35 and 36 are commonly used for ISL connections in many configurations1.
The process to identify the ISL ports is as follows:
Access the InfiniBand switch via the management interface.
Use the appropriate command to list the port configuration (this command can vary based on the switch's firmware).
Identify the ports configured for ISL, which will be indicated in the port configuration settings.
It's important to refer to the official Dell XtremIO Maintenance Achievement document or the InfiniBand switch documentation for the exact port numbers as they can differ based on the switch model and the cluster configuration1.

NEW QUESTION # 44
A multi X-Brick XtremlO X1 cluster is being installed. How many BBU connections, and of which type, are required per X-Brick?

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

Answer: B

Explanation:
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.
