Question 1
A company is using Snowflake Enterprise edition. A Data Engineer needs to optimize storage costs for a high-churn table that is recreated daily. The Engineer changes the table type from permanent to transient and sets the DATA_RETENTION_TIME_IN_DAYS = 1 . The Engineer also creates a clone of the table before the daily recreation process and sets the DATA_RETENTION_TIME_IN_DAYS = 1 for the clone. Four hours later, the table is accidentally dropped. Which methods can be used to retrieve the data? (Select TWO).
Question 2
A Data Engineer needs to optimize a very large fact table in a database that is frequently joined on the customer_id column and filtered by the transaction_time column. The customer_id column has nearly 50,000 unique values and the transaction_time data is a TIMESTAMP with millions of unique, discrete values with nanosecond precision. Which clustering key configuration will OPTIMIZE pruning and MINIMIZE credit consumption?
Question 3
A Data Engineer stores JSON data in a VARIANT column. Which factors will prevent JSON elements from being extracted into columnar storage, impacting query performance? (Select TWO).
Question 4
A Data Engineer needs to protect the ACCOUNT_NAME column in the dynamic table, ACCT_DIM . The table is sourced from the base table, ACCOUNT. How should the data in the dynamic table be protected?
Question 5
A Data Engineer is using a Snowpark Python User-Defined Function (UDF) that calls a third ‑ party fraud ‑ scoring REST API with the requests library. The API key is not hard ‑ coded in the handler. The UDF is registered as a permanent function and works in local testing, but when executed in Snowflake, it consistently fails with name ‑ resolution and network errors. The Engineer wants to avoid embedding the API key in code, running everything within Snowflake. How should these requirements be met?
Question 6
A Data Engineer needs to create an abstraction layer for an AI application that defines business metrics and relationships between the relevant data tables. Which solution options will meet the requirements? (Select TWO).

SnowPro Data Engineer DEA-C02 Practice and Access FAQs

Understand review, study tools and access before choosing your next step.

Who verifies the questions and answers?

Subject matter expert trainers in each niche review every question and answer before it enters the ExamPrepare database. Answer votes and discussions add perspectives after publication; they do not replace this review. Learn more on our methodology page.

How closely does the simulator match an exam?

The simulator uses vendor-style layouts and supported question interactions to help you practise navigation and pacing. Choose learning, practice or timed exam mode. Formats vary by exam; try the five-question sample to see the experience available for your certification.

What are hot questions?

Hot questions help you prioritise questions with stronger reporting or answer-vote activity. In the reading library, the filter selects questions with at least three recorded sightings or at least three votes for an answer. It has no recency cutoff and does not predict your exam questions. Use it alongside weaker topics and the exam objectives.

Can I read questions without starting a simulation?

Yes. Paid reading access lets you display 6, 10, 25, 50 or 100 questions per page, select a question range, filter for hot questions and show answers while reading. Choose the simulator whenever you want a learning, practice or timed exam session.

Can I download questions and answers as a PDF?

Each exam overview offers a free PDF sample of up to 10 supported questions. With paid reading access, you can also export supported single- and multiple-choice questions with their answers and images. Interactive question formats need the website and are not included as interactive PDF exercises.

How do votes and discussions relate to verified answers?

SME trainers review the questions and answers before publication. Imported answer reports show aggregate responses, while on-site votes and comments reflect participation on ExamPrepare. Use discussion to compare reasoning and investigate disagreements; a majority vote alone does not prove an answer correct.

What does a purchase unlock?

A purchase unlocks the complete question bank for the selected exam, access without CAPTCHA checks, reading controls, supported PDF exports and full learning, practice and timed simulation features. It covers that exam for the duration of the plan you choose, rather than every certification in the catalogue.

Where can I find my purchased exams and expiry dates?

Sign in to the account used for your purchase and open your profile. Your purchased exam library shows study links and access expiry dates so you can return to an exam and check how much access time remains.
