DEA-C02 Storage and Data Protection Practice Question
Which of the following describes the primary purpose of Snowflake's Fail-safe storage?
⚠ Common exam trap
Candidates confuse Fail-safe with Time Travel, mistakenly believing users can directly query or trigger data recovery from Fail-safe at any time.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
To provide a 7-day recovery period for catastrophic system failures.
Fail-safe is a critical component of Snowflake's data protection architecture, providing an immutable 7-day period that starts after the Time Travel window expires. It is intended for emergency recovery following system-level failures or catastrophic data loss. It is not designed for user-driven point-in-time recovery, which is the function of Time Travel, making Fail-safe a final, non-configurable safety mechanism for data durability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To allow users to query data state from up to 90 days ago.
Why it's wrong here
Querying historical data using Time Travel is a feature for user-driven recovery and auditing. This functionality relies on the DATA_RETENTION_TIME_IN_DAYS parameter, which is distinct from Fail-safe. Fail-safe is not accessible via SQL queries and does not provide an interface for users to retrieve past data states.
- ✓
To provide a 7-day recovery period for catastrophic system failures.
Why this is correct
Fail-safe acts as a disaster recovery mechanism for critical system failures. If data is permanently lost beyond the reach of Time Travel, Snowflake Support can potentially recover data from the Fail-safe window. This 7-day window is mandatory, immutable, and ensures that data remains protected against unexpected infrastructure-level incidents.
- ✗
To facilitate zero-copy cloning of large production databases.
Why it's wrong here
Zero-copy cloning is a feature that uses metadata to create a near-instant copy of a database without replicating the underlying data. It is unrelated to Fail-safe, which serves as a recovery buffer. Cloning relies on the shared storage architecture, while Fail-safe is a background retention process for deleted data.
- ✗
To enable cross-region replication for high availability.
Why it's wrong here
Cross-region replication is a separate feature that synchronizes database objects across different geographic locations to ensure high availability and disaster recovery. Fail-safe is a local storage protection mechanism and does not involve replicating data across regions or improving the availability of data in other Snowflake accounts.
