A retail company wants to use Big Data to personalize customer experiences and improve sales. The company has collected a large amount of data about customer demographics, purchase history, and online behavior.Which action would effectively leverage this data to achieve the company's goals?
Answer(s): D
Segmenting customers into groups based on their characteristics and preferences leverages big data to deliver personalized experiences and targeted promotions, directly improving engagement and sales.
What is an accurate statement about the Do-It-Yourself approach for building modern Infrastructure?
Answer(s): A
The Do-It-Yourself approach involves selecting and integrating individual products and services from multiple vendors - each offering specific functions and extensive configuration options - rather than relying on pre integrated or pre-packaged solutions.
What is a read miss in cache operations?
Answer(s): C
A read miss occurs when the requested data is not found in the cache, requiring the system to fetch the data from the underlying storage before supplying it to the application.
What are the two benefits of using sub-LUN tiering? (Choose two.)
Answer(s): C,D
Sub-LUN tiering moves only portions of a LUN (at the block level) to different performance tiers. This allows frequently accessed blocks to be placed on high-performance storage while less active blocks remain on lower-cost storage. As a result, it optimizes costs and provides fine-grained control over where data resides.
A company needs to rebuild a failed disk in its RAID 5 array.Which two factors should significantly impact the rebuild time? (Choose two.)
RAID 5 rebuild requires parity calculations and data reconstruction using the surviving disks. The rebuild time is heavily influenced by the size of the failed disk and the write performance of the remaining disks, as they must handle the additional workload during the rebuild process.
What is an advantage of deploying of deploying intelligent storage systems in the data center?
Intelligent storage systems automate data placement, optimization, and management, improving storage efficiency and performance while reducing administrative overhead.
A company is experiencing slow write performance on its RAID 6 array.What is the most likely cause of this performance bottleneck?
RAID 6 requires two parity blocks for each write operation, resulting in a higher write penalty compared to other RAID levels. This overhead from dual parity calculations is the most likely cause of slow write performance.
What is the main advantage of Network Attached Storage (NAS) systems over general-purpose servers?
NAS systems are specialized for file-level storage and provide a centralized platform for efficient file sharing across a network. This optimizes access, management, and performance compared to general-purpose servers handling files.
