Practice - 5 Tasks

1fill in blank

easy

Complete the code to enable point-in-time recovery on a DynamoDB table.

DynamoDB

response = client.update_continuous_backups(
    TableName='MyTable',
    PointInTimeRecoverySpecification={
        'PointInTimeRecoveryEnabled': [1]
    }
)

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

BFalse

C'Enabled'

D1

💡 Hint

Common Mistakes

Using a string like 'True' instead of the boolean True.

Setting the value to False which disables PITR.

To enable PITR, set PointInTimeRecoveryEnabled to True.

2fill in blank

medium

Complete the code to get the status of point-in-time recovery for a DynamoDB table.

DynamoDB

response = client.describe_continuous_backups(TableName=[1])

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

💡 Hint

Common Mistakes

Passing the table name without quotes causing a syntax error.

Using a variable name without defining it.

The table name must be a string literal, so use quotes around it.

3fill in blank

hard

Fix the error in the code to restore a DynamoDB table to a specific point in time.

DynamoDB

response = client.restore_table_to_point_in_time(
    SourceTableName='MyTable',
    TargetTableName='RestoredTable',
    RestoreDateTime=[1]
)

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

A"2023-01-01 12:00:00"

B'2023-01-01T12:00:00Z'

C2023-01-01 12:00:00

Ddatetime.datetime(2023, 1, 1, 12, 0, 0)

💡 Hint

Common Mistakes

Passing a string instead of a datetime object.

Using an incorrect datetime string format.

The RestoreDateTime parameter requires a datetime object, not a string.

4fill in blank

hard

Fill the blank to check if PITR is enabled and print the status.

DynamoDB

status = response['ContinuousBackupsDescription']['[1]']\nprint(f\"PITR enabled: {status}\")

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

CContinuousBackupsStatus

DBackupEnabled

💡 Hint

Common Mistakes

Using incorrect keys that do not exist in the response.

Mixing up status and enabled keys.

The PointInTimeRecoveryStatus under ContinuousBackupsDescription indicates if PITR is enabled ('ENABLED' or 'DISABLED').

5fill in blank

hard

Fill all three blanks to restore a DynamoDB table to a point in time with correct parameters.

DynamoDB

response = client.restore_table_to_point_in_time(
    SourceTableName=[1],
    TargetTableName=[2],
    RestoreDateTime=[3]
)

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

A'OriginalTable'

B'RestoredTable'

Cdatetime.datetime(2024, 6, 1, 15, 30, 0)

D'BackupTable'

💡 Hint

Common Mistakes

Passing table names without quotes.

Passing RestoreDateTime as a string.

Use string literals for source and target table names, and a datetime object for the restore time.
