This SAA-C03 practice question tests your understanding of design resilient architectures. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: dynamoDB PITR provides continuous backups for 35 days.. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A claims workflow requires point-in-time recovery and accidental-delete protection for a DynamoDB table. Which two settings should the architect enable?
Point-in-time recovery
PITR allows restoration to a specific second within the supported recovery window.
DAX
Why wrong: DAX improves read performance but does not provide recovery.
Deletion protection or tightly controlled delete permissions
Deletion protection and least-privilege controls reduce accidental table removal risk.
Global secondary indexes
Why wrong: GSIs support query access patterns but do not protect against data loss.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Point-in-time recovery
Point-in-time recovery (PITR) for DynamoDB enables continuous backups with 35-day granularity, allowing restoration to any second within that window. This directly satisfies the requirement for point-in-time recovery by providing the ability to restore the table to a specific state before a data corruption or accidental write event.
Key principle: DynamoDB PITR provides continuous backups for 35 days.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Point-in-time recovery
Why this is correct
PITR allows restoration to a specific second within the supported recovery window.

DAX
Why it's wrong here
DAX improves read performance but does not provide recovery.
Deletion protection or tightly controlled delete permissions
Why this is correct
Deletion protection and least-privilege controls reduce accidental table removal risk.
Related concept
DynamoDB PITR provides continuous backups for 35 days.
Global secondary indexes
Why it's wrong here
GSIs support query access patterns but do not protect against data loss.
Common exam traps
The trap here is that candidates often confuse DAX or GSIs as data protection mechanisms, but neither provides backup, recovery, or deletion prevention—they are performance and query optimization features, not resilience controls.
Detailed technical explanation
DynamoDB PITR restores the entire table to a new table using incremental backups stored in Amazon S3, with a restore time proportional to the table size. Deletion protection prevents accidental table drops by blocking DeleteTable API calls at the service level, while tightly controlled IAM delete permissions add a second layer of defense. In a real-world scenario, combining PITR with deletion protection ensures both recovery from logical errors (e.g., unintended updates) and protection against structural deletion.
Key takeaway
DynamoDB PITR provides continuous backups for 35 days.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
