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 consumer at Fabrikam has been using a Native App that maintains internal configuration settings and user preferences in tables created by the app's setup script. The consumer decides to drop the Native App object to free up resources. What happens to the data stored in the application's internal tables? (Select one!)
AThe data is transferred to the provider's application package stage for the consumer to retrieve later
BThe data is retained in a suspended state within the application package and can be recovered by reinstalling
CThe data is automatically exported to the consumer's default storage location before the application is dropped
DThe data is permanently lost because application-internal state is owned by the app object itself
Explanation
Application-internal state — tables and other stateful objects created by the setup script inside the Native App — is owned by the application object itself, not the consumer. When a consumer drops the Native App object, all internal state is permanently lost because there is no automatic backup or recovery mechanism. Consumers who need to preserve this data must explicitly export it before dropping the application. The data is not automatically moved to any consumer or provider storage location, nor is it retained in a recoverable suspended state. The application package is a provider-side artifact containing code and metadata, not per-consumer runtime data. Reinstalling the application creates a completely fresh instance with no prior state restored.
2. Fabrikam Analytics has built a Snowflake Native App for data quality validation. During development, the application package had DISTRIBUTION set to INTERNAL and was shared with internal test accounts. The team is now ready to publish the app on the public Snowflake Marketplace so that any Snowflake customer can discover and install it. Which two steps are required to make the app available to consumers outside Fabrikam's organization? (Select two!)
Multiple correct answersASet DISTRIBUTION = EXTERNAL on the application package and ensure the automated security scan passes
BCreate a Marketplace listing associated with the application package
CGrant the INSTALL APPLICATION privilege on the application package to the PUBLIC role
DSet MULTIPLE_INSTANCES = TRUE on the application package to allow installs from external Snowflake accounts
ESubmit a support ticket to Snowflake requesting manual partner engineer review and external publishing approval
Explanation
Publishing a Snowflake Native App to the public Marketplace requires two distinct steps. First, the provider must set DISTRIBUTION = EXTERNAL on the application package. This change immediately triggers the automated security scan run by Snowflake's Native App Anti-Abuse Pipeline Service — the scan must pass before external consumers can install the app. Second, a Marketplace listing must be created and linked to the application package. A listing is mandatory for EXTERNAL distribution; without it, the app cannot appear in the Snowflake Marketplace catalog regardless of the DISTRIBUTION setting. Granting INSTALL APPLICATION to the PUBLIC role is not the mechanism for Marketplace distribution. Marketplace access is governed through listings and the consumer install flow, not direct SQL privilege grants on the application package. The MULTIPLE_INSTANCES setting controls whether a consumer can install more than one instance of the app within their own account — it has no effect on enabling distribution to accounts outside the provider's organization. There is no manual support ticket or partner engineer review required as a prerequisite; the automated security scan is the required review mechanism, and it runs programmatically when DISTRIBUTION is set to EXTERNAL.
3. A provider at Aurora Data Services wants to list their Native App on the Snowflake Marketplace and make it discoverable to any Snowflake customer. The provider wants to offer a 14-day free trial period, after which consumers are billed a standard monthly subscription fee. Which listing type should the provider use? (Select one!)
APaid listing
BPrivate listing
CFree listing
DPersonalized listing
Explanation
A paid listing allows providers to offer their Native App on the Snowflake Marketplace with a defined pricing model, including subscription fees and optional trial periods. Free listings are for apps with no cost to the consumer. Personalized listings are used when pricing or contract terms are customized per consumer account, such as negotiated enterprise agreements with bespoke terms. Private listings restrict discoverability to specific consumer accounts and are not visible to the general Marketplace audience. Since Aurora Data Services wants broad public discoverability with a standard subscription pricing model, a paid listing is the correct choice.
4. A provider at Luminos Data Co has deployed a Native App containing proprietary machine learning algorithms implemented as UDFs. After deployment, consumers report they can query the information schema to view the full function body of these UDFs, exposing the provider's intellectual property. What is the correct remediation? (Select one!)
AMove the UDF logic into the manifest.yml artifacts block, which is not accessible to consumers after installation
BSet extension_code: false in the manifest.yml to prevent consumers from reading the handler implementation
CDeclare the UDFs and any views exposed to consumers as SECURE, which prevents consumers from viewing the function body or execution query plan
DEncrypt the UDF source code before uploading it to the provider stage so consumers cannot read the raw handler files
Explanation
Declaring UDFs and views as SECURE is the correct mechanism for protecting provider intellectual property in a Native App. The SECURE keyword prevents consumers from viewing the function body or the query execution plan, which would otherwise be accessible through the information schema. All UDFs and views exposed to consumers within a Native App should be defined as SECURE. Encrypting source code before stage upload is not a supported obfuscation mechanism — the SECURE attribute is what controls visibility at query time. The manifest.yml artifacts block holds configuration metadata and file paths, not function definitions. Setting extension_code: false disables non-SQL handler support entirely and would break the UDFs rather than hiding their implementation.
5. A developer at Lucerne Publishing is building a Native App that classifies documents using a stored procedure. The procedure must query a consumer-owned staging table that the consumer has bound as a reference at setup time. During integration testing, the procedure installs successfully but returns an access error indicating it cannot see the referenced consumer table. What change must the developer make to the stored procedure to allow it to access the consumer's table through the bound reference? (Select one!)
AAdd an EXTERNAL ACCESS INTEGRATION attribute to the procedure definition to allow cross-account data access
BGrant the application's owner role direct SELECT on the consumer table inside the setup script
CChange the procedure to EXECUTE AS OWNER so the application owner role can access all objects in the consumer's account
DChange the procedure to EXECUTE AS CALLER so the procedure runs with the consumer's session privileges
Explanation
Stored procedures that must access consumer-owned objects must use EXECUTE AS CALLER. In this execution mode, the procedure runs with the privileges of the consumer's calling session, which includes access to objects the consumer has bound via references. The default execution mode, EXECUTE AS OWNER, runs the procedure using the app's own owner role privileges, which are isolated from the consumer's account — this isolation is the cause of the access error in the test. EXTERNAL ACCESS INTEGRATION is for enabling outbound HTTP connections to external endpoints, not for accessing consumer database objects. Granting direct privileges to the application owner role in the setup script is not possible for consumer-owned tables, because the app cannot reference arbitrary consumer schemas at setup time without going through the reference binding mechanism.
