A. The last calendar month
B. The last 35 days
C. The last 10 days
D. The last week
Answer
B. The last 35 days
Explanation
With point-in-time recovery, the table can be restored to any point in time during the previous 35 days.
Amazon DynamoDB’s point-in-time recovery (PITR) feature allows you to restore a table to any point in time within the last 35 days. This feature provides continuous backups of your DynamoDB table, enabling you to recover from accidental writes, deletes, or any other unintended actions.
When you enable PITR for a table, DynamoDB maintains incremental backups of the table. These backups are automatically created and managed by DynamoDB, without affecting the table’s performance or availability. You can restore the table to any second in the last 35 days, up to the most recent five minutes.
To restore a table using PITR, you need to specify the source table, the restore timestamp, and a new table name. DynamoDB then restores the table data to the selected point in time, creating a new table with the specified name. The restored table has the same provisioned read and write capacity units, local and global secondary indexes, and other settings as the source table at the restore point.
It’s important to note that PITR only restores the data in the table, not the table’s settings or configuration. If you need to restore the table’s settings, such as auto scaling policies or tags, you’ll need to reconfigure them manually after the restore process.
In summary, Amazon DynamoDB’s point-in-time recovery feature allows you to restore a table to any point in time within the last 35 days, providing a reliable way to recover from accidental data loss or unintended modifications.
