EMC Dell XtremIO Design Achievement Sample Questions (Q15-Q20):

NEW QUESTION # 15
A customer has purchased an XtremlO X2-R, four X-Brick cluster. How many ports are available on a single InfiniBand Switch?

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

Answer: C

Explanation:
In a Dell XtremIO X2-R system, a four X-Brick cluster configuration includes two InfiniBand Switches1.
Each InfiniBand Switch in a multi X-Brick system, such as the X2-R, is included to interconnect the X-Bricks within the cluster. While the specific number of ports is not directly stated in the search results, the configuration implies a high number of ports to support the connectivity between multiple X-Bricks. Based on the available information and typical configurations of such systems, it is reasonable to infer that each InfiniBand Switch would have 36 ports to provide the necessary interconnectivity for a four X-Brick cluster.
References:
* The XtremIO X2 Specifications document provides details on system configurations and components, including InfiniBand Switches1.
* Additional information on InfiniBand Switches and their role in multi X-Brick systems can be found in the XtremIO X2 Specification Sheet2.

NEW QUESTION # 16
When troubleshooting SAN performance problems what would be a key indicator of a physical issue?

A. High Class 3 Discards
B. Low Buffer to Buffer Credits
C. High Buffer to Buffer Credits
D. High CRC error count

Answer: D

Explanation:
When troubleshooting SAN performance problems, a key indicator of a physical issue is a high CRC (Cyclic Redundancy Check) error count. CRC errors are indicative of corrupt data packets during transmission, which often points to issues such as faulty cables, bad ports, or other physical problems in the network infrastructure.
High CRC error counts can lead to retransmissions, reduced throughput, and overall degradation of SAN performance. Addressing the physical components associated with high CRC error counts is essential for restoring optimal SAN operations.
References:
* While the specific Dell XtremIO Design document was not available, general SAN troubleshooting guidelines and best practices indicate that CRC errors are a critical metric to monitor for physical connectivity issues1.
* Additional resources on SAN performance troubleshooting can be found in the support documentation for the XtremIO Family on Dell's official website2.

NEW QUESTION # 17
What is an accurate statement about XtremIO XVC refresh operations?

A. Refreshed volume cannot be resized
B. Only snapshot-to-production refresh is supported
C. O/S side device scan is not required
D. Unmount of a production volume is not required

Answer: D

Explanation:
XtremIO XVC (XtremIO Virtual Copies) allows for efficient snapshot management and operations, including the refresh of volumes. One of the key features of XVC is that it enables the refresh of a production volume from a snapshot without requiring the volume to be unmounted from the host. This capability is designed to minimize disruption and maintain continuous availability of data to applications during refresh operations.The refresh operation is handled within the XtremIO storage array, and the production volume remains accessible to the host during this process1.
References:
* The Dell XtremIO Design Achievement document provides information on the capabilities and features of XtremIO X2 systems, including XVC operations1.
* Additional details on XVC refresh operations can be found in the support documentation for the XtremIO Family on Dell's official website2.

NEW QUESTION # 18
A customer is adding a new volume to their XtremlO environment using the RESTful API. When attempting to create the volume, a response code of 400 is returned. What is the cause of this response code?

A. RESTful API command contains a syntax error
B. RESTful API command encountered an internal error
C. RESTful API command is not authorized
D. RESTful API command timed out

Answer: A

Explanation:
A response code of 400 in the context of RESTful API operations generally indicates that the request made by the client was malformed or contains a syntax error. This means that the data stream sent by the client to the server did not follow the rules as defined by the API specification.It could be due to various reasons such as incorrect request format, missing required parameters, or invalid parameter values1.
In the case of the Dell XtremIO environment, if a customer receives a 400 response code when attempting to create a volume via the RESTful API, it is likely due to a syntax error in the API command.The customer should review the API request to ensure that it conforms to the expected format and includes all necessary information as per the XtremIO API documentation2.
References:
* Community discussions on the Dell Technologies website where similar issues have been addressed and the cause of the 400 error was identified as a syntax error in the RESTful API command2.
* General information about the meaning of a 400 Bad Request error in REST APIs, which supports the
* conclusion that a syntax error is the cause1.

NEW QUESTION # 19
A user attempts to create a quorum disk for a host cluster. Volume parameters are:
Size = 1000 Kb
. Name 1 MB_Vol
However, the volume creation fails. What caused the process to fail?

A. XtremlO volumes cannot be quorum disks
B. Volume size is too small
C. Volume name is invalid
D. Quorum disks cannot have an 8 kB block size

Answer: B

Explanation:
The process to create a quorum disk for a host cluster failed because the volume size is too small12.
In a storage environment, the size of the volume plays a crucial role.If the volume size is too small, it may not be able to accommodate the data required for the quorum disk, leading to a failure in the creation process12.
In this case, the volume size is specified as 1000 Kb, which is likely insufficient for a quorum disk in a host cluster environment12.Therefore, increasing the volume size could potentially resolve this issue12.
