Common Mistakes

Choosing GLACIER for frequently accessed data causes slow retrieval.

The STANDARD storage class is the default for frequently accessed data in S3.

2fill in blank

medium

Complete the code to specify the S3 storage class for infrequent access.

AWS

aws s3 cp file.txt s3://mybucket/ --storage-class [1]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using GLACIER instead causes longer retrieval times.

STANDARD_IA is for data accessed less frequently but requires rapid access when needed.

Fix the error in the storage class name to use Glacier archival storage.

AWS

aws s3 cp file.txt s3://mybucket/ --storage-class [1]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using GLACIER_IR when standard Glacier is required.

GLACIER is the correct storage class for archival with longer retrieval times.

4fill in blank

hard

Fill both blanks to set the storage class to One Zone-Infrequent Access and enable encryption.

AWS

aws s3 cp file.txt s3://mybucket/ --storage-class [1] --sse [2]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using STANDARD_IA instead of ONEZONE_IA or wrong encryption flag.

ONEZONE_IA stores data in one availability zone for lower cost, and AES256 enables server-side encryption with Amazon S3-managed keys.

5fill in blank

hard

Fill all three blanks to copy a file to Glacier storage with KMS encryption and specify the storage class.

AWS

aws s3 cp file.txt s3://mybucket/ --sse [1] --storage-class [2] --metadata-directive [3]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using AES256 instead of aws:kms or missing metadata directive.

aws:kms enables KMS encryption, GLACIER sets the archival storage class, and REPLACE tells S3 to replace metadata during the copy.
