Exam Overview
The SnowPro Specialty: Native Apps (NAS-C01) certification validates specialized knowledge, skills, and best practices for designing and deploying native application workloads within Snowflake's Data Cloud. The exam assesses proficiency across the full lifecycle of native application development—from understanding the Native App Framework architecture and constructing application packages to implementing versioning, release management, and publishing on the Snowflake Marketplace. Candidates are tested on their ability to apply Snowflake's programming constructs, integrate Snowpark, manage data sharing and monetization strategies, and enforce security and access control within native apps.
The NAS-C01 is one of three certifications in the SnowPro Specialty series, alongside Snowpark (SPS-C01) and Gen AI (GES-C01), each targeting practitioners with deep, production-level expertise in specific Snowflake feature areas. The exam is scored on a scaled 0–1000 point scale with a passing threshold of 750, is administered through Pearson VUE (at testing centers or via remote proctoring), and costs $375 USD per attempt.
Who Should Take This Exam
This certification is designed for software engineers, data engineers, and platform developers who have at least one year of hands-on experience building and deploying native applications using the Snowflake Native App Framework in production environments. Ideal candidates are professionals who architect, develop, test, and release native apps distributed via the Snowflake Marketplace, and who routinely work with application packages, setup scripts, manifest files, container services, and lifecycle management workflows.
Candidates are expected to have working knowledge of at least one Snowflake-supported language such as Python, familiarity with standard software development lifecycle (SDLC) practices, and experience integrating security controls, billing events, and monetization mechanisms into their native app solutions.
Prerequisites
There are no mandatory prerequisites listed to sit for NAS-C01, but Snowflake strongly recommends that candidates hold the SnowPro Core certification or possess equivalent foundational knowledge of Snowflake's platform before pursuing this specialty. Core competency in SQL and at least one Snowflake-supported programming language (particularly Python) is expected, as is familiarity with Snowpark for building data pipelines and application logic.
Beyond technical knowledge, candidates should have practical, production-level experience working with the Snowflake Native App Framework—including constructing and versioning application packages, writing setup scripts, managing permissions, and understanding deployment and release pipelines. Candidates with experience in CI/CD tooling, application distribution, and data marketplace operations will be especially well-prepared.
Exam Format
The NAS-C01 exam consists of approximately 55 scored questions, delivered entirely in multiple-choice format. Candidates are given 60 minutes to complete the exam. The exam is administered through Pearson VUE and can be taken either at a physical testing center from Pearson VUE's global network of 1,000+ locations, or remotely via online proctoring from a home or office environment.
Scoring uses a scaled system ranging from 0 to 1,000 points, and a passing score of 750 is required. The exam costs $375 USD per attempt. Upon passing, the certification remains valid for two years, after which candidates must retake the current version of the exam to maintain their credential.

Study Tips
- Start with the official SnowPro Specialty: Native Apps Exam Study Guide available on learn.snowflake.com, which maps directly to the four exam domains and their weightings—prioritize Design & Creation (35%) and Deployment (25%) as they carry the most weight.
- Complete Snowflake University's Native App Framework training course, available through learn.snowflake.com, to build hands-on familiarity with application packages, setup scripts, manifest files, and the full application lifecycle.
- Build and deploy at least one native app from scratch using the Snowflake Native App Framework in a Snowflake trial account, covering the complete workflow: package creation, versioning, permissions setup, testing, and publishing to a private listing.
- Practice with Snowflake's official SnowPro Practice Exams (available at learn.snowflake.com/en/certifications/snowpro-practice-exams/), which are built using the same domain weightings and question style as the live NAS-C01 exam—note that each practice exam can only be attempted once.
- Study the Snowflake Native App Framework developer documentation closely, especially topics covering billing events, consumer permissions, container services, event sharing, and Marketplace monetization models, as these are heavily tested in the Deployment domain.
- Review Snowflake's security model as it applies to native apps—understand the difference between application roles, consumer grants, and provider-defined permissions, since access control is a cross-cutting concern tested across multiple domains.
- Use Snowpark (Python) to build application logic within a native app, as the exam expects familiarity with Snowflake-supported languages; practice creating stored procedures, UDFs, and Streamlit-based UIs packaged within an application.
Career Benefits
Professionals who earn the NAS-C01 certification demonstrate production-level expertise in one of Snowflake's most strategic growth areas—native application development—which differentiates them in a market where demand for Snowflake-skilled engineers continues to outpace supply. Certified professionals are well-positioned for roles such as Snowflake Native App Developer, Data Platform Engineer, Cloud Application Architect, and Marketplace Solution Provider, with mid-to-senior-level Snowflake developers in the United States earning between $120,000 and $190,000 per year in base salary, and total compensation ranging significantly higher in top-tier technology organizations.
As ISVs (independent software vendors) and enterprise data teams increasingly adopt the Snowflake Marketplace to distribute and monetize data products, demand for engineers who can architect and operate native apps within Snowflake's governed environment is growing. The NAS-C01 complements other Snowflake credentials—particularly the SnowPro Core and SnowPro Specialty: Snowpark—and together these certifications form a compelling credential stack for professionals building Snowflake-native data products and commercial applications.
Sample Questions
5 sample questions with answers and explanations. The full bank has 600 questions, enough for 6 full-length practice exams.
Preview — answers shown1. A provider at Helios Systems is managing their Native App's rollout using release channels. They want to maintain a separate internal validation environment for their own engineers while also sharing a pre-release version with select enterprise consumer accounts for early feedback before general availability. Which two statements accurately describe the behavior of the QA and ALPHA release channels in this context? (Select two!)
Multiple correct answersAThe QA channel is designed for internal provider testing and does not require applications to pass automated security scans before versions are added to it
BThe ALPHA channel is restricted to internal provider accounts only and cannot be used to share pre-release versions with external consumer accounts
CThe ALPHA channel supports external collaboration with select consumer accounts and requires applications to pass automated security scans before versions can be assigned to it
DThe DEFAULT channel does not enforce security scan requirements for application packages that have INTERNAL distribution configured
EVersions added to the QA channel are automatically promoted to ALPHA after a 48-hour validation window if no critical defects are detected by Snowflake monitoring
Explanation
Snowflake Native App release channels serve distinct and well-defined purposes in the release lifecycle. The QA channel is intended exclusively for internal provider testing and validation workflows. Because versions in QA never reach external consumer accounts, automated security scans are not required before adding versions to this channel, enabling faster iteration cycles during active development. The ALPHA channel serves a fundamentally different purpose: it is designed for external collaboration, allowing providers to share pre-release versions with specific consumer accounts for structured early feedback and validation. Because ALPHA versions reach external consumers, they are subject to the same automated security scan requirements enforced for the DEFAULT production channel. The DEFAULT channel is the general availability channel for all consumers and also enforces security scans. Versions do not automatically promote between channels—promotion is always a deliberate provider action. The INTERNAL versus EXTERNAL distribution setting on the application package determines whether a Marketplace listing is required, but security scan enforcement is governed by the release channel classification, not the distribution setting.
2. A developer at Axion Analytics issues a CREATE APPLICATION PACKAGE FINANCIAL_INSIGHTS statement and immediately receives a naming conflict error. No application package with that name exists in the account. Which of the following best explains the root cause of this error? (Select one!)
AA warehouse named FINANCIAL_INSIGHTS already exists in the account, and warehouses share the namespace with application packages
BThe name FINANCIAL_INSIGHTS contains underscores, which are not permitted in application package identifiers
CThe user executing the command lacks the SYSADMIN role required to create application packages in the account
DA database named FINANCIAL_INSIGHTS already exists in the account, and application packages share the same namespace as databases
Explanation
Application packages occupy the same namespace as databases in Snowflake. If a database with the identical name already exists in the account, a CREATE APPLICATION PACKAGE command will fail with a naming conflict even though no application package with that name exists yet. This is a fundamental architectural constraint of the Native App Framework—application packages are not stored in a separate namespace but share the account-level database namespace, meaning the two object types cannot coexist under the same name. Underscores are valid characters in Snowflake identifiers and do not cause naming errors. The scenario specifies a naming conflict error rather than a privilege error, ruling out the role requirement as the cause. Warehouses maintain their own separate namespace and do not conflict with application package or database names.
3. A provider at Fabrikam Dev has been iteratively patching version 1.0 of their Native App to deliver frequent bug fixes and performance improvements. They have now created patch 15 for version 1.0, and the application package has DISTRIBUTION set to EXTERNAL. How many patches of version 1.0 will be included in the automated security scan? (Select one!)
APatches 1 through 15 are bundled and evaluated as a single combined artifact
BAll 15 patches are individually scanned to ensure full version history compliance
COnly the 10 most recent patches are scanned regardless of the total patch count
DOnly the most recent patch is scanned since earlier patches are considered superseded
Explanation
When DISTRIBUTION is set to EXTERNAL, Snowflake's automated security scanner evaluates only the 10 most recent patches for a given version. With 15 total patches on version 1.0, patches 6 through 15 fall within the active scanning window while patches 1 through 5 are outside it. This scanning limit is specific to EXTERNAL distribution — QA channel releases do not require security scans at all, while ALPHA and DEFAULT channels enforce the same 10-patch window. The limit does not reduce the maximum number of patches allowed per version, which can be up to 130 patches per version. Providers should be aware that although older patches remain accessible to consumers who have not yet upgraded, those older patches may not have been re-validated under the most current security scanning rules. Scanning every individual patch regardless of count would be computationally prohibitive, and patches are never merged into a single artifact for scanning purposes.
4. A Snowflake Native App provider at TerraMetrics has set DISTRIBUTION = EXTERNAL on their application package and has been iterating rapidly, creating 15 patches for version 3.0 over the past sprint cycle. A new team member attempts to assign patch 3 of version 3.0 to a release directive for a canary consumer group, but the operation fails. Patches 6 through 15 function correctly in release directives. What is the correct explanation for this behavior? (Select one!)
ASecurity scanning results expire after 72 hours, and older patches must be recreated to obtain a fresh scan before they can be used in release directives
BPatches older than 30 calendar days are automatically archived by Snowflake and can no longer be assigned to release directives for EXTERNAL applications
CFor application packages with DISTRIBUTION set to EXTERNAL, only the 10 most recent patches per version are eligible for security scanning and publication to consumers
DAssigning non-sequential patches to release directives requires submitting a variance request through the Snowflake partner portal before the assignment can proceed
Explanation
When an application package has DISTRIBUTION set to EXTERNAL, Snowflake enforces a constraint where only the 10 most recent patches for any given version are eligible for automated security scanning and subsequent publication. In this scenario with 15 total patches on version 3.0, only patches 6 through 15 fall within the eligible window. Patch 3 is outside that window and cannot be assigned to a release directive or published to consumers, regardless of whether it passed security review when it was originally created. This limit keeps security evaluations focused on current code and prevents distribution of significantly outdated patch states. Patches are not managed based on calendar age — the limit is purely ordinal, based on recency relative to other patches within the same version. There is no partner portal variance request process for individual patches. Security scan results do not expire on a 72-hour timer; they are associated with the patch at the time of creation.
5. A developer at Pacific Analytics Group is designing the setup script for a Native App. The app collects consumer-specific configuration preferences, such as alert thresholds and report layout settings, that must survive application upgrades. The developer plans to store these preferences in a versioned schema, reasoning that its automatic recreation on each upgrade will keep the schema structure current. What critical flaw exists in this design? (Select one!)
AVersioned schemas cannot contain TABLE objects and are restricted exclusively to views, stored procedures, and UDFs, making them unsuitable for storing row-level preference data
BVersioned schemas require the ACCOUNTADMIN role to create and cannot be instantiated within the restricted app owner execution context used by the setup script
CThe CREATE OR ALTER VERSIONED SCHEMA syntax requires manifest_version: 2 to be set in manifest.yml; apps using manifest_version: 1 will encounter a compilation error during installation
DVersioned schemas and all their contents are automatically dropped and recreated on every upgrade, meaning all stored consumer configuration data will be permanently lost each time the app is patched or versioned
Explanation
Versioned schemas in Snowflake Native Apps are designed exclusively for code objects such as stored procedures, UDFs, and views that need to reflect the current version of the application. On every upgrade—whether a patch or a full version change—the versioned schema is automatically dropped and recreated from the new version's artifacts. Any table data stored within a versioned schema is permanently destroyed during this recreation cycle. Consumer configuration preferences and all other persistent state must be stored in a standard, non-versioned schema using CREATE TABLE IF NOT EXISTS patterns, which preserves the table and its data across upgrades. The CREATE OR ALTER VERSIONED SCHEMA syntax is available regardless of the manifest_version setting. Versioned schemas are created within the standard app owner execution context without requiring elevated roles. Versioned schemas can technically contain tables, but doing so causes data loss on every upgrade, which is precisely the anti-pattern this question illustrates.
