EMC Dell XtremIO Design Achievement Sample Questions (Q36-Q41):

NEW QUESTION # 36
A customer has a complex virtualized environment and wants to see a topology view from virtual or physical hosts down to the storage array volumes to identify application to storage dependencies.
Which Dell EMC product provides this solution?

A. XtremIO VAAI plug in
B. Technician Advisor
C. ViPR SRM
D. AppSync

Answer: C

Explanation:
ViPR SRM (Storage Resource Management) is the Dell EMC product that provides a comprehensive topology view from virtual or physical hosts down to the storage array volumes. This tool is designed to help customers manage complex virtualized environments by offering insights into application-to-storage dependencies.ViPR SRM delivers detailed reporting and analytics, which can be used to optimize storage performance and capacity planning1.
References:
* The Introduction to XtremIO X2 Storage Array document provides information on the system features and management tools available for XtremIO arrays, which includes details on how ViPR SRM can be used to visualize and manage the storage infrastructure1.
* Additional resources on the Dell EMC support site offer documentation and guides on how to effectively use ViPR SRM for storage resource management2.

NEW QUESTION # 37
What is an example of a Decision Support Systems (DSS) workload?

A. Data Warehouse
B. Order Entry applications
C. Online banking applications
D. Airline reservation systems

Answer: A

Explanation:
Explore
A Decision Support System (DSS) is a computer-based tool designed to aid individuals and organizations in making informed decisions. It integrates data, models, and analytical tools to solve complex problems and support strategic planning.A DSS is particularly effective in handling large volumes of data and applying sophisticated algorithms to generate insights that guide effective choices1.
A Data Warehouse is an example of a DSS workload because it is a centralized repository for storing large amounts of data from multiple sources.Its primary purpose is to facilitate reporting and analysis1. Data Warehouses are designed to perform queries and analysis on historical data and are an integral part of business intelligence that supports decision-making processes.
References:
* A comprehensive explanation of what constitutes a DSS and its applications can be found in various resources, including those that define a Data Warehouse as a key component of DSS1.
* The "Introduction to XtremIO X2 Storage Array" document by Dell Technologies provides insights into the system features that support DSS workloads like Data Warehouses2.

NEW QUESTION # 38
What should the Oracle Redo Log block size be set to in order to prevent log entries from being misaligned by read-modify-write operations for an Oracle database?

A. 24 kB
B. 8 kB
C. 16 kB
D. 4 kB

Answer: B

Explanation:
The Oracle Redo Log block size is recommended to be set to 8 kB.This is based on the best practices for Oracle 19c Database, where it was found that increasing the size of the Oracle redo logs can improve database performance12. However, it's important to note that not every workload will show significant performance increase when increasing the size of the redo logs. Customers should evaluate the AWR to determine if the redo logs have an associated high number and duration of wait times.If the redo logs show a possible bottleneck, then increasing the size of the redo logs could improve performance2.

NEW QUESTION # 39
Which XtremlO X2 hardware component provides a backup power source to save journaling data during an unplanned emergency shutdown?

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

Answer: C

Explanation:
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.

NEW QUESTION # 40
An XtremlO administrator wants to understand the I/O transfer process. What are the parts of a typical I/O transfer?

A. Protocol, header, data, and handshaking
B. Metadata, header, data, and log
C. Protocol, header, data, and address
D. Negotiation, header, data, and acknowledgement

Answer: A

Explanation:
A typical I/O transfer involves several components that work together to ensure data is correctly sent and received. These components include:
* Protocol: This defines the rules for how data is transmitted between devices. It ensures that the sender and receiver are using a common language and standards.
* Header: The header contains metadata about the data being transferred, such as source and destination addresses, error checking codes, and sequencing information.
* Data: This is the actual payload or information that is being transferred.
* Handshaking: This part of the process involves the exchange of control messages before the actual data transfer begins. It establishes the parameters of the communication channel and confirms that both sender and receiver are ready for the transfer.
These components are essential for the successful completion of an I/O transfer, ensuring that data is accurately and reliably transmitted from one point to another.
References:
* The Dell XtremIO Design documents provide a detailed understanding of the product features, functionality, use cases, and configurations, which includes the I/O transfer process as a fundamental aspect of storage array operations1.
* Additional resources on I/O transfer processes can be found in the support documentation for the XtremIO Family on Dell's official website2.
