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 Point-in-time recovery (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 payments API requires point-in-time recovery and accidental-delete protection for a DynamoDB table. Which two settings should the architect enable? The team wants the control to be enforceable during normal operations.
Deletion protection or tightly controlled delete permissions
Deletion protection and least-privilege controls reduce accidental table removal risk.
Point-in-time recovery
PITR allows restoration to a specific second within the supported recovery window.
Global secondary indexes
Why wrong: GSIs support query access patterns but do not protect against data loss.
DAX
Why wrong: DAX improves read performance but does not provide recovery.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Deletion protection or tightly controlled delete permissions
Deletion protection (Option A) prevents accidental table deletion by blocking drop-table operations, which is enforceable during normal operations. Point-in-time recovery (Option B) enables continuous backups with 35-day granularity, allowing restoration to any second within that window. Together, they satisfy the requirements for accidental-delete protection and point-in-time recovery.
Key principle: DynamoDB Point-in-time recovery (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.
Deletion protection or tightly controlled delete permissions

Global secondary indexes
Why it's wrong here
GSIs support query access patterns but do not protect against data loss.
DAX
Why it's wrong here
DAX improves read performance but does not provide recovery.
Common exam traps
The trap here is that candidates often confuse point-in-time recovery with backup solutions like AWS Backup or assume that GSIs or DAX provide data protection, when in fact they serve entirely different purposes (performance optimization and caching).
Detailed technical explanation
Point-in-time recovery (PITR) uses continuous backups stored in a separate Amazon S3 bucket, enabling restores to any second within the last 35 days with a one-second granularity. Deletion protection is a table-level setting that, when enabled, blocks all DeleteTable API calls regardless of IAM permissions, ensuring the table cannot be dropped even by administrators. Note that PITR does not protect against accidental writes or deletes of individual items—only table-level deletion is blocked by the deletion protection setting.
Key takeaway
DynamoDB Point-in-time recovery (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.
