最新的 Storage Administrator D-XTR-DS-A-24 免費考試真題 (Q29-Q34):

問題 #29
A storage administrator is configuring SAN switches and zoning to connect a four X-Brick XtremlO array. A VMware ESXi server is hosted on a blade chassis with 16 HBA ports.
In addition, the SAN consists of two separate SAN switches.
What is the recommended XtremlO best practice for zoning?

A. Two HBA connections per host
Single initiator/multiple targets per zone
Maximum of 16 paths for each device
Host connected to each SAN switch
B. Single Storage Controller HBA port to the first switch
Single Storage Controller HBA port to the second switch
Single initiator/multiple targets per zone
Maximum of 4 paths for each LUN per zone
C. Two HBA connections per host connected to a single switch
Multiple initiators/multiple targets per zone
Maximum of 4 paths for each LUN per zone
D. First Storage Controllers' HBA ports to the first switch
Second Storage Controllers' HBA ports to the second switch
Multipath all host ports to single LUNs per zone

答案：A

解題說明：
For a four X-Brick XtremIO array, the recommended best practice for zoning in a SAN environment with VMware ESXi servers is to have two HBA connections per host, with each host connected to both SAN switches. This configuration allows for redundancy and high availability. The zoning should be set up with a single initiator (the HBA on the host) to multiple targets (the storage controllers' HBA ports) per zone. This ensures that each host has multiple paths to the storage, allowing for failover and load balancing.The maximum number of paths for each device should be 16 to prevent exceeding the path limits and to maintain optimal performance1.
References:
* Dell Technologies community discussions on XtremIO Zoning Best Practices provide insights into the recommended zoning configurations for different XtremIO setups1.
* The Host Configuration Guide for XtremIO, which can be found on the Dell EMC support site, offers detailed instructions on zoning best practices for XtremIO storage arrays2.

問題 #30
An XtremlO administrator has a cluster consisting of two X2 X-Bricks in production. The administrator plans to expand the cluster to a total of four X2 X-Bricks.
How many snapshots and volumes can the newly upgraded XtremlO cluster support?

A. 0
B. 1
C. 2
D. 3

答案：D

解題說明：
An XtremIO cluster's ability to support snapshots and volumes scales with the number of X-Bricks in the cluster.According to the documentation, an XtremIO X2 cluster can support up to 32K objects (root volumes + snapshots) per cluster1. Therefore, with the expansion from two to four X2 X-Bricks, the cluster would be able to support up to 32,768 snapshots and volumes.
References:
* The Dell EMC XtremIO X2: Next-Generation All-Flash Array document states the infrastructural scale supporting up to 32K objects per cluster1.
* Additional information on the scalability and performance of XtremIO X2 clusters can be found in the Introduction to XtremIO X2 Storage Array document2.

問題 #31
When creating XtremlO volumes for a host, which operating systems will benefit by changing the default logical block size for applications consisting of 4 KB I/Os?

A. RHEL and IBM AIX
B. Microsoft Windows and RHEL
C. VMware ESX and Microsoft Windows
D. Sun Solaris and HP-UX

答案：C

解題說明：
When creating XtremIO volumes for a host, operating systems like Microsoft Windows and RHEL (Red Hat Enterprise Linux) will benefit from changing the default logical block size to better match applications that consist of 4 KB I/Os. This is because these operating systems are commonly used with applications that have a
4 KB I/O size, and aligning the logical block size with the application I/O size can improve performance by reducing the need for read-modify-write cycles.
For instance, in Windows environments, the NTFS file system often uses a default cluster size of 4 KB, which aligns well with a 4 KB logical block size.Similarly, for RHEL, the Ext4 file system can be configured with a
4 KB block size, which is a common setting for many Linux-based applications12.
References:
* Discussions on Dell Technologies community forums indicate that changing the logical block size can prevent issues with unaligned I/O and is part of a larger configuration strategy for optimizing storage performance3.
* The Reference Architecture Guide for Dell EMC XtremIO documents mention using a block size of 64 KB for database data and log file drives after the installation of the operating system in the VMs, for Windows and RHEL operating systems respectively12. This suggests that the block size is an important consideration for performance tuning in these environments.

問題 #32
Which XtremlO X2 hardware component provides a backup power source to save journaling data during an unplanned emergency shutdown?

A. BBU
B. NVRAM
C. PSU
D. SuperCap

答案：D

解題說明：
In the event of an unplanned emergency shutdown, the XtremIO X2 hardware component that provides a backup power source to save journaling data is the SuperCapacitor (SuperCap). The SuperCap is designed to maintain power to the system long enough to ensure that all in-flight writes are committed to non-volatile memory, preserving data integrity.Unlike a battery backup unit (BBU) which may provide power for a longer duration, the SuperCap is specifically designed for short-term power retention to protect data during transient power interruptions1.
References:
* The User Guide for XtremIO, which includes power down and power up procedures, would typically detail the role of the SuperCap in emergency shutdown scenarios1.
* Additional information on the hardware components and their functions can be found in the Reference Architecture Guide for Dell EMC XtremIO2.

問題 #33
What is a benefit of XtremIO All Flash arrays?

A. Cost per I/O per GB is lower than spinning disk
B. Cost per GB is lower than spinning disk
C. Cost per GB is the same as spinning disk
D. Cost per I/O per GB is the same as spinning disk

答案：A

解題說明：
XtremIO All Flash arrays provide a significant benefit in terms of cost per I/O per GB when compared to traditional spinning disks. This is due to the higher performance and efficiency of flash storage, which delivers faster data access speeds and better I/O rates. As a result, the cost per I/O operation, when spread over the total capacity of the storage (GB), is lower for all-flash arrays.This efficiency translates into better overall value, especially for workloads that require high I/O throughput1.
References:
* It is a common understanding that all-flash arrays, like XtremIO, offer better performance and efficiency compared to spinning disks, which results in a lower cost per I/O per GB1.
* The "Introduction to XtremIO X2 Storage Array" document from Dell Technologies highlights the efficiency of the storage array, which contributes to reducing the $/GB cost of storage2.
* Additional data from industry sources supports the notion that all-flash storage can be more cost-effective in the long run due to operational cost reductions and lower total cost of ownership (TCO) over time1.
