Question 1 of 65

A table is loaded using Snowpipe and truncated afterwards. Later, a Data Engineer finds that the table needs to be reloaded, but the metadata of the pipe will not allow the same files to be loaded again.
How can this issue be solved using the LEAST amount of operational overhead?
Answer choices
Show answer

Correct answer: D

Recreating the pipe with CREATE OR REPLACE PIPE resets the pipe’s file-loading metadata, allowing previously loaded staged files to be processed again. Snowpipe normally tracks loaded filenames to prevent duplicate ingestion, even if the target table is later truncated. FORCE=TRUE is not available for Snowpipe-managed COPY operations, and modifying or waiting for file metadata adds unnecessary operational effort.

Question 2 of 65

A company using Snowflake works with a third party that provides economic data. The third-party provider recently moved their data to Snowflake.
How can the company access the third-party data in Snowflake with the LEAST amount of operational overhead?
Answer choices
Show answer

Correct answer: B

A Snowflake share lets the provider grant the company direct, secure access to selected database objects without copying or replicating data. The company creates a database from the shared data and queries it using its own Snowflake account, while the provider retains control over the source objects and permissions. This minimizes administration and avoids maintaining replicated databases or separate user accounts.

Question 3 of 65

A Data Engineer made modifications to staged files and re-staged them. A pipe is running but the changed data is not appearing in the table.
What step should the Engineer take in order to see the changed data without duplicating data?
Answer choices
Show answer

Correct answer: D

Creating new files with the changed data causes Snowpipe to treat them as new ingestion candidates. Snowpipe tracks loaded files by filename and does not reload a file that has already been processed, even if its contents are later modified and staged again. Replacing or recreating the pipe does not reset this file-load history safely, and reloading existing files could duplicate data.

Question 4 of 65

How can a Data Engineer return all the errors encountered during a previous file upload that used the COPY command?
Answer choices
Show answer

Correct answer: B

The VALIDATE table function returns all errors encountered during a previous COPY command execution when provided the COPY statement’s query ID. It exposes row-level loading errors, allowing the Data Engineer to review rejected records and diagnose file or data-format problems. VALIDATE_PIPE_LOAD is intended for Snowpipe loads, not COPY commands, while the information schema and account usage views do not provide this COPY error detail.

Question 5 of 65

A company called IOТ Corporation has subsidiary companies in Germany and Japan.
The German subsidiary has a Snowflake account called IOTGER in AWS region EU (Frankfurt) (Region ID: eu-central-1).
The Japanese subsidiary has a Snowflake account called IOTJPN in Azure region Japan East (Tokyo) (Region ID: japaneast).
The subsidiaries are totally independent of one another, and their Snowflake accounts belong to different Snowflake organizations.
A Data Engineer needs to share data in a database called IOT PROD from the German account to the Japanese account.
What steps need to be taken by the German subsidiary so that the Japanese subsidiary can use the shared data?
Answer choices
Show answer

Correct answer: D

Because the consumer account is in Azure Japan East while the source is in AWS Frankfurt, the data cannot be shared directly from IOTGER. The German subsidiary creates IOTGER2 in the consumer’s region, replicates IOT_PROD to that account, and creates the share there. IOTGER2 can then add IOTJPN as a consumer because both accounts are in the same region and cloud platform. Direct sharing from IOTGER would not satisfy the cross-cloud, cross-region requirement.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla
Italy
The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.
