1Which Snowflake edition is designed for organizations that require the highest level of security, including PHI and PII data protection?
A.Standard Edition
B.Enterprise Edition
C.Business Critical Edition
D.VPS (Virtual Private Snowflake) Edition
Explanation: VPS (Virtual Private Snowflake) Edition provides the highest level of security with dedicated, isolated infrastructure for organizations handling the most sensitive data including PHI and PII. While Business Critical Edition offers enhanced security features, VPS provides complete isolation.
2What is the default behavior when a virtual warehouse is created in Snowflake?
A.It starts automatically and runs indefinitely
B.It remains suspended until a query is executed
C.It runs for exactly 10 minutes then auto-suspends
D.It requires manual activation before any use
Explanation: When a virtual warehouse is created in Snowflake, it remains in a suspended state until a query is executed that requires compute resources. This is part of Snowflake consumption-based pricing model.
3In Snowflake architecture, which layer is responsible for storing the actual data in micro-partitions?
A.Storage Layer
B.Compute Layer (Virtual Warehouses)
C.Cloud Services Layer
D.Metadata Layer
Explanation: The Storage Layer in Snowflake is responsible for storing data in a columnar format using micro-partitions. This layer is separate from the Compute Layer, which handles query processing.
4What is the maximum size of a single micro-partition in Snowflake?
A.8 MB
B.16 MB
C.50 MB
D.100 MB uncompressed, 16 MB compressed
Explanation: Snowflake stores data in micro-partitions of up to 100 MB of uncompressed data (approximately 16 MB compressed). This size optimizes query pruning and parallel processing.
5Which Snowflake object is used to organize data into a logical group of schemas and other database objects?
A.Schema
B.Database
C.Warehouse
D.Role
Explanation: A Database in Snowflake is the top-level container that organizes schemas and other database objects. Schemas exist within databases and contain objects like tables, views, and stages.
6What happens when you create a clone of a database in Snowflake?
A.A complete physical copy of all data is created
B.Only metadata is copied; data is shared via pointers
C.Only empty schema structures are copied
D.A backup is created in a separate region
Explanation: Snowflake zero-copy cloning creates a metadata copy that points to the same underlying micro-partitions. No data is physically duplicated initially, making cloning nearly instantaneous and storage-efficient.
7Which type of table in Snowflake stores data persistently and requires explicit DML operations to modify?
A.Temporary Table
B.Transient Table
C.Permanent Table
D.External Table
Explanation: Permanent Tables are the standard table type in Snowflake that store data persistently. They require explicit DML operations (INSERT, UPDATE, DELETE) to modify data and have full Time Travel and Fail-safe protection.
8What is the purpose of a Stream object in Snowflake?
A.To load data from external sources
B.To track changes to a table for incremental processing
C.To execute SQL statements in sequence
D.To replicate data across regions
Explanation: A Stream in Snowflake is used to track changes (INSERTS, UPDATES, DELETES) made to a table. It provides a change data capture mechanism for incremental data processing, commonly used with Tasks for ETL workflows.
9Which Snowflake feature automatically suspends a virtual warehouse after a period of inactivity?
A.Auto-scaling
B.Auto-suspend
C.Auto-resume
D.Auto-clustering
Explanation: Auto-suspend is the feature that automatically suspends a virtual warehouse after a specified period of inactivity (default is 10 minutes). This helps control costs by stopping credit consumption when the warehouse is not in use.
10What is the minimum retention period for Time Travel in Enterprise Edition of Snowflake?
A.0 days
B.1 day
C.7 days
D.90 days
Explanation: Enterprise Edition provides a minimum Time Travel retention period of 1 day (24 hours). The maximum is 90 days for Enterprise Edition and above. Standard Edition has a fixed 1-day retention.
