Client Redirect is a Snowflake feature designed to support business continuity and disaster recovery in multi-account, multi-region architectures. When configured, it allows client applications to automatically connect to a secondary Snowflake account if the primary account becomes unavailable. This secondary account must be part of a configured failover group and promoted to act as the primary during a failover event.

The correct behavior of Client Redirect is to redirect client connections transparently to another Snowflake account—typically in a different region—where replicated data and objects are available and the account is acting as the primary (Answer D). This minimizes downtime and avoids the need for manual connection string updates across applications.

The feature does not simply provide alternate login URLs, nor does it dynamically route queries across multiple active accounts. It also does not automatically select the “closest” region; redirection follows the configured failover topology. For SnowPro Architect candidates, this question emphasizes understanding Snowflake’s native disaster recovery mechanisms and how Client Redirect integrates with failover groups.

QUESTION NO: 47 [Security and Access Management]

A call center processes sensitive PII and PHI data. Requirements:

Object owners and privileged roles must see sensitive columns.

Pre-tokenized data must be de-tokenized at query time.What should be used? (Select TWO).

A. Object tagging

B. Materialized views

C. External tokenization

D. Dynamic Data Masking

E. Role-Based Access Control (RBAC)

Answer: D, E

Dynamic Data Masking is a Snowflake security feature that conditionally masks or reveals column values at query time based on the executing role (Answer D). This allows privileged users (such as object owners or compliance roles) to see clear-text PII/PHI, while other users see masked or tokenized values. Because masking is evaluated at query time, it supports de-tokenization logic when the role is authorized.

Role-Based Access Control (RBAC) underpins this behavior by defining which roles are privileged and allowed to view unmasked data (Answer E). Masking policies are evaluated in the context of the active role, making RBAC essential for enforcing correct access.

Object tagging alone does not enforce access control. Materialized views duplicate data and do not support dynamic de-tokenization logic. External tokenization is not required when Snowflake masking policies can handle conditional reveal. This question tests SnowPro Architect knowledge of advanced column-level security and privacy controls.

QUESTION NO: 49 [Snowflake Data Engineering]

A table contacts_data contains a VARIANT column with nested JSON data.

Which queries correctly retrieve the first name value "Snow"? (Select TWO).

A. SELECT o[customer][name][first]::STRING FROM contacts_data;

B. SELECT o['customer']['name']['first']::STRING FROM contacts_data;

C. SELECT o:['customer']:['name']:['first']::STRING FROM contacts_data;

D. SELECT o:Customer.Name.First::STRING FROM contacts_data;

E. SELECT o:customer.name.first::STRING FROM contacts_data;

Answer: B, E

Snowflake supports multiple syntaxes for accessing elements in VARIANT columns. Bracket notation with quoted keys is valid for object traversal, making option B correct. Dot notation with colon syntax is also valid and commonly used for readability, as shown in option E.

Option A is invalid because unquoted identifiers inside brackets are interpreted as column names, not JSON keys. Option C contains incorrect syntax combining brackets and colons. Option D is invalid because JSON key names are case-sensitive unless quoted, and the provided structure uses lowercase keys.

Understanding VARIANT traversal syntax is a core SnowPro Architect skill for semi-structured data handling and transformation.

QUESTION NO: 50 [Cost Control and Resource Management]

An Architect is evaluating compute and storage costs related to performance optimization techniques.

Which Snowflake performance optimizations have storage costs associated with them? (Select THREE).

A. Rekeying

B. Materialized views

C. Clustering a table

D. Query Acceleration Service

E. Search Optimization Service

F. Multi-cluster virtual warehouse

Answer: B, C, E

Some Snowflake performance features require additional storage to maintain auxiliary data structures. Materialized views store precomputed query results and therefore consume storage (Answer B). Clustering a table can increase storage usage due to additional micro-partitions created during reclustering operations (Answer C).

Search Optimization Service builds and maintains search access paths that persist as additional metadata structures, incurring storage costs (Answer E). In contrast, Query Acceleration Service and multi-cluster warehouses affect compute usage only. Rekeying is a security operation and does not create separate storage structures.

This question tests SnowPro Architect understanding of cost tradeoffs between compute and storage when selecting optimization techniques.

 A reader account is a type of Snowflake account that allows external users to access data shared by a provider account without being a Snowflake customer. A reader account can be created and managed by the provider account, and can use the Snowflake web interface or JDBC/ODBC drivers to query the shared data. A reader account is billed to the provider account based on the credits consumed by the queries1. A secure view is a type of view that applies row-level security filters to the underlying tables, and masks the data that is not accessible to the user. A secure view can be shared with a reader account to provide granular and governed access to the data2. In this scenario, creating a reader account for the partner and sharing the data sets as secure views would be the most cost-effective and secure design, while using the required Snowflake features, because:

It would avoid the data transfer and storage costs of using an S3 bucket as a destination, and the potential security risks of exposing the data to unauthorized access or modification.

It would avoid the complexity and overhead of publishing the data sets on the Snowflake Marketplace, and the potential loss of control over the data ownership and pricing.

It would avoid the need to create a database user for the partner and grant them access to the required data sets, which would require the partner to have a Snowflake account and consume the provider’s resources.
