Hadoop - Modern Data Architecture with Hadoop

ARaw zone for ingestion and a curated zone optimized with indexes for analytics

BSandbox zone for raw data and processed zone for fast queries

CProcessed zone for raw data and raw zone for cleaned data

DCurated zone for raw data and sandbox zone for analytics

Step-by-Step Solution

Solution:

Step 1: Identify zones for raw and cleaned data
Raw zone stores unprocessed data; curated zone holds cleaned, optimized data.
Step 2: Consider query performance
Curated zone can be optimized with indexes or formats for fast querying.
Step 3: Eliminate incorrect options
Sandbox is for experimentation, not raw data; processed zone is for cleaned data, not raw.
Final Answer:
Raw zone for ingestion and a curated zone optimized with indexes for analytics -> Option A
Quick Check:
Raw = ingestion, curated = optimized queries [OK]

Quick Trick: Raw stores data; curated optimized for queries [OK]
