AWS - S3 Fundamentals

You want to store 10 TB of backup data that you rarely access but must keep for years. You want to minimize cost but still be able to retrieve data within a few hours if needed. Which S3 storage class should you choose and why?

ASTANDARD_IA, because it balances lower cost with quick access.

BSTANDARD, because it offers instant access despite higher cost.

CGLACIER, because it is the cheapest but retrieval takes days.

DGLACIER INSTANT RETRIEVAL, because it offers low cost and milliseconds access.

Step-by-Step Solution

Solution:

Step 1: Analyze access frequency and retrieval time needs
Data is rarely accessed but must be retrievable within hours, not instantly.
Step 2: Compare storage classes for cost and retrieval speed
STANDARD_IA offers lower cost than STANDARD and retrieval in milliseconds to seconds; GLACIER has longer retrieval times.
Final Answer:
STANDARD_IA, because it balances lower cost with quick access. -> Option A
Quick Check:
Rare access + quick retrieval = STANDARD_IA [OK]

Quick Trick: Rare access + hours retrieval? Pick STANDARD_IA [OK]

Common Mistakes:

MISTAKES

Choosing GLACIER despite slow retrieval
Picking STANDARD and paying too much
Confusing GLACIER INSTANT RETRIEVAL (not standard GLACIER)
