Exam Overview
The SnowPro Advanced: Architect (ARA-C01) is Snowflake's role-based advanced certification that validates the skills required to design, deploy, and optimize comprehensive data architecture solutions on the Snowflake Data Cloud. It tests a candidate's ability to architect end-to-end data flows from source to consumption, select appropriate Snowflake-native and third-party tooling to meet performance and scalability requirements, and deploy shared datasets using Snowflake Marketplace and Data Exchange. The exam covers four weighted domains: Accounts and Security, Snowflake Architecture, Data Engineering, and Performance Optimization.
This certification is positioned as an advanced-level credential, building directly on the SnowPro Core and requiring demonstrated production-grade expertise. Candidates are expected to understand Snowflake's multi-cluster architecture, virtual warehouse configuration, data governance controls including column- and row-level security, RBAC hierarchies, CI/CD integration, and disaster recovery mechanisms such as Time Travel, Fail-safe, and zero-copy cloning. Snowflake updates its exam content periodically to reflect platform releases, so candidates should always reference the current official exam study guide.
Who Should Take This Exam
The ARA-C01 is designed for professionals who operate as architects in production Snowflake environments with a minimum of two years of hands-on experience. Primary job titles include Solution Architect, Data Architect, Database Architect, Cloud Architect, and Systems Architect. Candidates typically own enterprise-scale architectural decisions spanning multi-account strategy, data security and compliance design, workload isolation, and cross-organizational data sharing.
Strong candidates have practical experience building and optimizing complex ETL/ELT pipelines, implementing Snowflake security and governance frameworks, working with multiple data modeling methodologies (Star, Snowflake schema, Data Vault), and coding outside of SQL in contexts such as DevOps or DataOps workflows. Professionals who manage or advise on Snowflake deployments across Business Critical or higher editions will find the content especially relevant.
Prerequisites
Snowflake requires candidates to hold an active SnowPro Core Certification before sitting for the ARA-C01 exam. The Core certification ensures a baseline understanding of Snowflake's foundational architecture, storage and compute separation, and standard platform features. Snowflake does not enforce additional formal prerequisites beyond the Core cert, but the exam is calibrated for candidates with substantial real-world exposure.
Recommended knowledge includes proficiency with Snowflake virtual warehouse sizing and multi-cluster configuration, SQL and SQL analytics, Snowflake's object hierarchy (organization, account, database, schema, object), data security concepts such as RBAC and network policies, Snowpipe and streaming ingestion patterns, Streams and Tasks for pipeline automation, and familiarity with cloud provider networking on AWS, Azure, or GCP. Prior experience with DevOps tooling for CI/CD pipelines integrated with Snowflake is also beneficial.
Exam Format
The ARA-C01 exam consists of 65 scored questions delivered over 115 minutes, administered either via online proctoring through Kryterion's Webassessor platform or at an onsite Kryterion testing center. Question types include multiple choice (single correct answer), multiple select (multiple correct answers), and true/false. The exam fee is $375 USD per attempt.
Scoring uses a scaled system ranging from 0 to 1000, with a passing threshold of 750. Scores are reported on this scale rather than as a raw percentage, meaning scaled scoring accounts for minor variations in question difficulty across exam versions. Candidates who need to renew the credential can take the shorter recertification exam (ARA-R01, $188 USD) instead of repeating the full exam; passing the Advanced recertification also automatically renews the associated SnowPro Core certification.

Study Tips
- Download and work through the official ARA-C01 Exam Study Guide from learn.snowflake.com before doing anything else — it maps every testable subdomain with explicit topic lists and domain weights, giving you a precise study checklist rather than broad categories.
- Complete the Snowflake-provided instructor-led or on-demand courses on Snowflake's learning portal (learn.snowflake.com), particularly the Advanced Architect learning path, which aligns content directly to the four exam domains.
- Build hands-on labs in a Snowflake trial account covering multi-account architecture scenarios: set up RBAC hierarchies with custom roles, configure network policies, create Streams and Tasks pipelines, and experiment with Snowpipe vs. Snowpipe Streaming to understand real trade-offs tested in scenario questions.
- Focus significant study time on Domain 2 (Snowflake Architecture, 30% weight) — particularly data sharing across regions and cloud providers, Time Travel cost and table-type interactions, and CI/CD integration patterns, as these are the highest-weighted topics with the most scenario-based question depth.
- Practice interpreting Query Profile outputs and know when to apply clustering keys, search optimization, materialized views, or warehouse resizing — Domain 4 questions are scenario-driven and require understanding which optimization technique is appropriate given specific workload and cost constraints.
- Use the Snowflake documentation on Business Critical edition features (Tri-Secret Secure, customer-managed keys, Private Link) and multi-account organization features, as these advanced security and governance topics appear in Domain 1 and are not covered in depth by the SnowPro Core curriculum.
- Take at least two full-length timed practice exams under real conditions (115 minutes, 65 questions) using reputable sources such as the practice sets on CertSafari or CertificationPractice.com to calibrate your pacing and identify remaining weak domains before your scheduled exam date.
Career Benefits
The SnowPro Advanced: Architect credential signals enterprise-grade Snowflake expertise in a market where demand for certified Snowflake architects significantly outpaces supply. Certified professionals qualify for senior and principal-level roles such as Senior Data Architect, Cloud Solutions Architect, and Principal Data Engineer at organizations that have standardized on Snowflake as their data platform. Industry salary data for 2025 places SnowPro Advanced Architects at approximately $185,000 USD annually in the United States, with certified professionals reporting 10–15% salary increases post-certification relative to non-certified peers in equivalent roles.
Unlike the vendor-neutral AWS Solutions Architect or Google Professional Data Engineer credentials, the ARA-C01 directly certifies deep platform-specific expertise that organizations actively seek when scaling Snowflake deployments to Business Critical or higher editions with multi-region, multi-cloud, or data-sharing requirements. Holding both the SnowPro Core and Advanced: Architect certifications creates a recognized dual credential in the Snowflake ecosystem, and passing the Advanced recertification exam simultaneously renews the Core, reducing long-term maintenance overhead. Snowflake's partner network and marketplace ecosystem also give certified architects visibility through Snowflake's official certification directory.
Sample Questions
5 sample questions with answers and explanations. The full bank has 592 questions, enough for 5 full-length practice exams.
Preview — answers shown1. Fabrikam BI Platform operates a Medium virtual warehouse serving 200 business analysts running interactive reports. Usage peaks sharply Monday through Friday from 8 AM to 10 AM with 180 simultaneous users, while the remaining 22 hours of the day average only 5 to 10 concurrent users. The team wants to eliminate query queuing during peak hours while minimizing credit consumption during off-peak hours with no manual warehouse management required. What should they configure? (Select one!)
AConfigure a multi-cluster warehouse in Auto-scale mode with min clusters set to 1 and max clusters sized to absorb peak concurrency, with auto-suspend enabled.
BEnable the Query Acceleration Service on the existing Medium warehouse to distribute peak query processing across serverless compute.
CResize the warehouse permanently to X-Large to provide enough compute slots to accommodate 180 concurrent users at all times.
DConfigure a multi-cluster warehouse in Maximized mode with max clusters set to 8 and auto-suspend set to 1 minute.
Explanation
Multi-cluster warehouses in Auto-scale mode automatically provision additional compute clusters when query queuing is detected during peak demand and remove clusters as demand subsides. Auto-suspend then stops idle clusters to eliminate credit consumption during off-peak periods. Setting min clusters to 1 ensures only a single cluster runs during the 5-to-10-user baseline hours, while max clusters scales upward to eliminate queuing for the 180-user morning peak — all without manual intervention. Permanently resizing to X-Large provides constant large compute even when only 5-10 users are active, consuming significantly more credits across the 22 daily off-peak hours. Maximized mode runs all clusters simultaneously at all times regardless of actual demand, producing the same excessive off-peak cost as permanent resizing. Query Acceleration Service offloads portions of individual large queries to serverless compute but does not address concurrency queuing, which results from many users submitting separate queries simultaneously.
2. Contoso Analytics is building a Secure Data Sharing solution to expose processed data to external partners. The engineering team has built the following objects in ANALYTICS_DB: a permanent table SALES_FACT, a regular non-secure view SALES_SUMMARY_VW, a secure view CUSTOMER_MASKED_VW, a regular materialized view MONTHLY_AGGREGATES_MV, a secure materialized view REGIONAL_TOTALS_SMV, and a stored procedure CALCULATE_DISCOUNT_SP. The team wants to include every shareable object in the share. Which three objects can be included? (Select three!)
Multiple correct answersASALES_FACT (permanent table)
BSALES_SUMMARY_VW (regular non-secure view)
CCUSTOMER_MASKED_VW (secure view)
DMONTHLY_AGGREGATES_MV (regular materialized view)
EREGIONAL_TOTALS_SMV (secure materialized view)
FCALCULATE_DISCOUNT_SP (stored procedure)
Explanation
Secure Data Sharing supports only tables, secure views, secure materialized views, and secure UDFs. Regular views, regular materialized views, and stored procedures cannot be included in a share. SALES_FACT as a permanent table is shareable. CUSTOMER_MASKED_VW as a secure view is shareable and commonly used to apply column-level masking or row filtering before exposing data to partners. REGIONAL_TOTALS_SMV as a secure materialized view is shareable. SALES_SUMMARY_VW cannot be included because regular views expose the underlying query logic and are explicitly excluded from sharing. MONTHLY_AGGREGATES_MV cannot be included because only secure materialized views — not regular materialized views — are permitted in shares. CALCULATE_DISCOUNT_SP cannot be shared because stored procedures are not a supported shareable object type regardless of their implementation details.
3. Northwind Data Services loads daily supplier inventory snapshots from an external stage. File sizes vary considerably, ranging from 800 rows to 80,000 rows per file depending on the supplier. The data governance policy specifies: files in which more than 5% of rows contain formatting or parsing errors must be entirely rejected and requeued for vendor remediation; files that pass the quality threshold must load their valid rows while silently skipping individual error rows; the daily batch must continue processing all remaining files even when a given file is rejected. Which COPY INTO ON_ERROR value satisfies all three policy conditions? (Select one!)
AON_ERROR = SKIP_FILE_5% to skip entire files where the proportion of error rows exceeds 5% while loading valid rows from files that meet the quality threshold, with erroneous rows in those files individually skipped and the batch continuing across all remaining files
BON_ERROR = ABORT_STATEMENT to terminate the entire COPY INTO operation immediately when the first error row is encountered in any file, halting all further loading
CON_ERROR = SKIP_FILE to skip any file containing even a single parsing error, ensuring only completely error-free files are loaded into the target table
DON_ERROR = CONTINUE to skip individual error rows across all files regardless of each file's overall error rate and continue processing the entire batch without any file-level quality filtering
Explanation
SKIP_FILE_5% enforces a percentage-based file quality gate. When the proportion of error rows in a file exceeds 5%, Snowflake skips the entire file and continues to the next one. For files where errors remain at or below the 5% threshold, Snowflake loads only valid rows — erroneous rows within those files are individually skipped and never written to the target table — and batch processing continues uninterrupted. The percentage-based variant is especially appropriate when file sizes vary widely: a fixed error-count option such as SKIP_FILE_40 would represent a 5% rate in an 800-row file but only 0.05% in an 80,000-row file, producing inconsistent policy enforcement across suppliers. SKIP_FILE rejects every file containing any error at all, far exceeding the 5% tolerance and discarding large volumes of valid rows unnecessarily. CONTINUE applies no file-level quality filter, meaning a file with 60% error rows would still partially load its valid rows, violating the governance requirement that high-error files be entirely rejected and requeued. ABORT_STATEMENT halts the entire COPY INTO operation on the very first error encountered, preventing all subsequent files from loading and making it impossible to complete the daily batch.
4. Fabrikam Insurance is onboarding to Snowflake and requires a data security model in which even Snowflake's own infrastructure teams cannot access customer data at rest. The security team demands the ability to immediately invalidate all access to their encrypted data by revoking a key they exclusively control. Which Snowflake feature and edition combination satisfies this requirement? (Select one!)
AAutomatic annual key rekeying with AES-256-bit encryption, available on all Snowflake editions
BTri-Secret Secure, which creates a composite encryption key combining Snowflake's key and the customer's key stored in AWS KMS, Azure Key Vault, or GCP Cloud KMS, available on Business Critical edition and above
CPrivateLink network connectivity combined with IP-based network policies to prevent unauthorized data access, available on Business Critical edition
DColumn-level encryption using external tokenization through masking policies that reference the customer's own key vault, available on Enterprise edition
Explanation
Tri-Secret Secure is the only Snowflake feature that prevents even Snowflake employees from accessing a customer's encrypted data at rest. It creates a composite encryption key that requires both Snowflake's managed key and the customer's key stored in their own cloud KMS (AWS KMS, Azure Key Vault, or GCP Cloud KMS). If the customer revokes their key from the KMS, Snowflake cannot reconstruct the composite key and therefore cannot decrypt the data, satisfying the requirement for customer-controlled access revocation. This feature is exclusive to Business Critical and higher editions. Automatic annual key rekeying is a standard AES-256-bit rotation feature managed entirely by Snowflake — it does not prevent Snowflake from accessing data and is available as a default on Business Critical+. External tokenization with masking policies can obfuscate column values at query time but the underlying raw data remains fully accessible to Snowflake internally. PrivateLink and network policies govern network-level connectivity and do not affect the encryption architecture that protects data stored on disk.
5. Contoso Financial Services is subject to strict data sovereignty regulations requiring that the organization, not Snowflake, must retain ultimate control over all encryption keys protecting stored data. The compliance team requires that if the organization revokes access to their encryption infrastructure, Snowflake must be rendered permanently unable to decrypt any stored data. They have provisioned a Snowflake Business Critical edition account. Which Snowflake feature should the architect configure to satisfy this requirement? (Select one!)
AApply dynamic data masking policies to all columns containing sensitive customer data
BEnable automatic annual key rotation for Snowflake-managed AES-256 encryption at the account level
CImplement PrivateLink to ensure all data traffic remains within the organization's private network boundary
DConfigure Tri-Secret Secure using a customer-managed key stored in the organization's AWS KMS
Explanation
Tri-Secret Secure creates a composite encryption key combining a Snowflake-managed key with a customer-managed key stored in AWS KMS, Azure Key Vault, or GCP Cloud KMS. Because decryption requires both halves of the composite key simultaneously, revoking the customer-managed key from the cloud KMS makes it cryptographically impossible for Snowflake to decrypt any stored data, satisfying the regulatory requirement. Automatic AES-256 key rotation is always active in all Snowflake editions, but Snowflake retains sole ownership of those keys, meaning the customer cannot independently revoke access. PrivateLink creates a private network connection that prevents data from traversing the public internet but does not affect Snowflake's ability to access and decrypt data stored in its own infrastructure. Dynamic data masking controls query-time visibility of column values for specific roles but does not protect the underlying stored data from Snowflake's infrastructure access.
