最新的 Storage Administrator D-XTR-MN-A-24 免費考試真題 (Q23-Q28):

問題 #23
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 more than half of the BBU COM cables results in a loss of service
C. Failure of one serial cable makes the BBU not visible to the cluster's environment monitoring
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.

問題 #24
Into which directory must the XtremApp software be copied on the XMS?

A. /home
B. /xtremapp
C. /media
D. /images

答案：B

解題說明：
The XtremApp software must be copied into the /xtremapp directory on the XtremIO Management Server (XMS). This directory is specifically designated for the XtremApp software, ensuring that it is stored in the correct location for installation and execution1.
The process for copying the software typically involves:
Accessing the XMS via a secure shell (SSH) connection.
Navigating to the root directory.
Locating or creating the /xtremapp directory.
Using the appropriate command to copy the XtremApp software from its source location to the /xtremapp directory on the XMS.
It is important to follow the Official Dell XtremIO Maintenance Achievement document for the correct procedures and to ensure that the software is placed in the proper directory for successful installation and operation1.

問題 #25
When comparing XtremlO X1 to XtremlO X2, how much memory is installed in a Storage Controller that has a DAE attached with 400 GB SSDs?

A. X1: 384 GB; X2: 384 GB
B. X1: 256 GB; X2: 384 GB
C. X1: 256 GB; X2: 512 GB
D. X1: 512 GB; X2: 1024 GB

答案：C

解題說明：
When comparing XtremIO X1 to XtremIO X2, the amount of memory installed in a Storage Controller with a DAE attached with 400 GB SSDs differs. For the X1, it is 256 GB, while for the X2, it is 512 GB. This increase in memory in the X2 model supports higher performance and improved handling of data operations.

問題 #26
In addition to the cluster name, which parameters are required for creation of the cluster?

A. Code level of the XMS and the installed image code, and IP addresses of the X-Bricks
B. IP addresses for the second X-Brick and XMS name
C. Upgrade software version, XMS code level, and expected number of X-Bricks
D. Expected number of X-Bricks, IP address of X1-SC1, and package name

答案：D

解題說明：
When creating a cluster, in addition to the cluster name, the following parameters are required: the expected number of X-Bricks, the IP address of X1-SC1 (the first Storage Controller), and the package name. These parameters are essential for setting up the cluster configuration and ensuring proper communication between components.

問題 #27
In an XtremIO X2, what is the maximum number of lifetime cycles for NVRAM?

A. 7,000
B. 5,000
C. 10,000
D. 4,000

答案：C

解題說明：
In an XtremIO X2 system, the maximum number of lifetime cycles for NVRAM is 10,000. This number represents the total count of write and erase cycles the NVRAM can endure throughout its lifespan, ensuring data integrity and reliability over time.
