Recall & Review

beginner

What is the AWS S3 Standard storage class used for?

The S3 Standard storage class is used for frequently accessed data that requires high durability, availability, and low latency. It is ideal for active data and websites.

What does the S3 Infrequent Access (IA) storage class offer?

S3 IA is for data that is accessed less often but still needs to be quickly available when requested. It offers lower storage costs than Standard but charges for retrieval.

beginner

Describe the main use case for the S3 Glacier storage class.

S3 Glacier is designed for long-term archival storage where data is rarely accessed. It offers very low storage costs but retrieval can take minutes to hours.

beginner

Which S3 storage class provides the fastest data retrieval?

The S3 Standard storage class provides the fastest data retrieval with low latency and high throughput.

intermediate

What is a key cost difference between S3 Standard and S3 IA?

S3 IA has lower storage costs than Standard but charges a fee each time data is retrieved, making it cost-effective for infrequent access.

Which S3 storage class is best for data that is accessed frequently?

A S3 Infrequent Access

B S3 Glacier

C S3 Standard

D S3 One Zone-IA

S3 Standard is optimized for frequent access with high availability and low latency.

What is a characteristic of S3 Glacier storage?

A Instant data retrieval

B No retrieval fees

C High storage cost with frequent access

D Low storage cost with delayed retrieval

S3 Glacier offers very low storage costs but retrieval can take minutes to hours.

Which S3 storage class charges retrieval fees?

A S3 Infrequent Access

B Both B and C

C S3 Standard-IA

D S3 Standard

Both S3 Infrequent Access and Standard-IA charge fees when data is retrieved.

If you want to store backup data that you rarely access but want to keep for years, which storage class is best?

A S3 Glacier

B S3 Infrequent Access

C S3 Standard

D S3 Intelligent-Tiering

S3 Glacier is designed for long-term archival with low cost and infrequent access.

Which storage class offers the highest availability and durability for active data?

A S3 Standard

B S3 Glacier

C S3 One Zone-IA

D S3 Intelligent-Tiering

S3 Standard provides 99.99% availability and 99.999999999% durability for active data.

Explain the differences between S3 Standard, S3 Infrequent Access, and S3 Glacier storage classes.

Think about how often you access the data and how fast you need it.

When would you choose S3 Glacier over S3 Standard or IA?

Consider backup or archival scenarios.
