AWS Certified Data Analytics Specialty 2021 - Hands-On! - Amazon DynamoDB-Storing Large Objects

The video tutorial explains how to store large objects efficiently using Amazon S3 and DynamoDB. It highlights that while DynamoDB has a 400KB item size limit, large objects can be stored in S3 with a reference in DynamoDB. The tutorial provides a cost analysis, showing that using S3 for infrequently accessed items is more cost-effective. It concludes with recommendations on when to use S3 and DynamoDB based on access frequency and object size.

What is the maximum size of an item that can be directly stored in DynamoDB?

• 400 kilobytes

• 300 kilobytes

• 200 kilobytes

• 100 kilobytes

Why is it recommended to store large objects in Amazon S3 instead of DynamoDB?

• S3 is faster

• DynamoDB cannot store objects larger than 400 kilobytes

• DynamoDB is more expensive

• S3 is more secure

What is a key advantage of using S3 for storing underutilized items?

• Higher availability

• Lower storage costs

• Faster retrieval times

• Better data encryption

How does the cost of storing a 300 kilobyte object in DynamoDB compare to S3 when accessed infrequently?

• DynamoDB is cheaper

• S3 is cheaper

• Both are equally expensive

• Cost depends on the region

When is DynamoDB a better choice than S3 for storing items?

• When items are accessed frequently

• When items are larger than 400 kilobytes

• When items require encryption

• When items are rarely accessed
