D-ISM-FN-01 PDF 117 Questions

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?

  1. Store the data in a traditional relational database for easy access and analysis
  2. Send generic marketing emails to all customers promoting new products and offers
  3. Ignore the data and rely on initiation to make business decisions
  4. Segment customers into different groups based on its characteristics and preferences

Answer(s): D

Explanation:

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?

  1. Utilizes products and services from the vendors that provide specific functions with more configuration options
  2. Combines the datacenter components into a single standalone computing platform managed by software
  3. Utilizes preconfigured preinstalled and prepackaged vendor ready solutions
  4. Combines datacenter components into a distributed Infrastructure platform manages by software

Answer(s): A

Explanation:

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?

  1. Fetching requested data that is already in cache
  2. Deleting data from the cache
  3. Fetching requested data that is not in cache
  4. Writing data to the cache

Answer(s): C

Explanation:

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.)

  1. Simplified storage management
  2. Reduced need for storage tiering policies
  3. Cost optimization
  4. Granular control over data placement
  5. Reduced need for storage capacity

Answer(s): C,D

Explanation:

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.)

  1. Network bandwidth between the server and the storage array
  2. Capacity of the cache memory
  3. Write performance of the remaining disks
  4. Capacity of the failed disk

Answer(s): C,D

Explanation:

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?

  1. Reduces the amount of data to be replicated, migrated, and backed up
  2. Migrates data from a data center to the cloud at no cost
  3. Enables efficient and optimized storage and management of information
  4. Reduces the complexity of managing information by creating silos of storage

Answer(s): C

Explanation:

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?

  1. Write penalty associated with dual parity calculations
  2. Insufficient storage on the RAID controller
  3. High read I/O load on the array
  4. Increased network latency between the server and the storage array

Answer(s): A

Explanation:

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?

  1. Support FC protocols to access files over FC-SAN
  2. Reduce the size of the object ID
  3. Increase data redundancy
  4. Centralize and optimizes file sharing operations

Answer(s): D

Explanation:

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.

i just took my oracle exam and let me tell you, this exam dumps was a lifesaver! without them, iam not sure i would have passed. the questions were tricky and the answers were obscure, but the exam dumps had everything i needed. i would recommend to anyone looking to pass their oracle exams with flying colors (and a little bit of cheating) lol.

22. if you need to make sure that one computer in your hot-spot network can access the internet without hot-spot authentication, which menu allows you to do this? answer is ip binding and not wall garden. wall garden allows specified websites to be accessed with users authentication to the hotspot
