Snowflake SnowPro Advanced Administrator ADA-C02 Sample Questions (Q50-Q55):

NEW QUESTION # 50
A retailer uses a TRANSACTIONS table (100M rows, 1.2 TB) that has been clustered by the STORE_ID column (varchar(50)). The vast majority of analyses on this table are grouped by STORE_ID to look at store performance.
There are 1000 stores operated by the retailer but most sales come from only 20 stores. The Administrator notes that most queries are currently experiencing poor pruning, with large amounts of bytes processed by even simple queries.
Why is this occurring?

A. The cardinality of the stores to transaction count ratio is too low to use the STORE_ID as a clustering key.
B. The table is not big enough to take advantage of the clustering key.
C. Sales across stores are not uniformly distributed.
D. The STORE_ID should be numeric.

Answer: C

Explanation:
Clustering is effective when data distribution across the clustering key is relatively uniform. In this case, most transactions are concentrated in only 20 of the 1000 stores, leading to skewed data distribution. This imbalance causes poor pruning, since large portions of micro-partitions still need to be scanned, even for queries targeting specific stores.

NEW QUESTION # 51
What are characteristics of data replication in Snowflake? (Choose three.)

A. Users can have unlimited primary databases and they can be replicated to an unlimited number of accounts if all accounts are within the same organization.
B. Users must be granted REPLICATIONADMIN privileges in order to enable replication.
C. Databases created from shares can be replicated.
D. Replication can only occur within the same cloud provider.
E. The ALTER DATABASE ... ENABLE REPLICATION TO ACCOUNTS command must be issued from the primary account.
F. To start replication run the ALTER DATABASE ... REFRESH command on the account where the secondary database resides.

Answer: C,E,F

Explanation:
Replication must be enabled on the primary account using ALTER DATABASE ... ENABLE REPLICATION TO ACCOUNTS.
To refresh replicated data, ALTER DATABASE ... REFRESH is executed on the secondary database.
Databases created from shares can also be replicated.

NEW QUESTION # 52
What is the default data retention period for transient databases, schemas, and tables for Snowflake Enterprise edition and higher?

A. 30 days
B. 90 days
C. 1 day
D. 14 days

Answer: C

Explanation:
Transient databases, schemas, and tables are designed for temporary or non-critical data and therefore have a default Time Travel retention period of one day. Even in Enterprise Edition and higher, the default retention for transient objects remains one day, although permanent objects can have longer retention periods configured.

NEW QUESTION # 53
Which statement allows a Snowflake Administrator to retrieve the network policy applied to their Snowflake account?

A. DESC NETWORK POLICY <policy_name>;
B. SHOW PARAMETERS LIKE ‘NETWORK POLICY’ IN ACCOUNT;
C. SHOW NETWORK POLICIES IN ACCOUNT;
D. SHOW NETWORK POLICIES;

Answer: B

Explanation:
The network policy applied at the account level is stored as an account parameter. Using a SHOW PARAMETERS command with the filter for NETWORK POLICY at the account scope returns the currently configured value, which identifies the network policy associated with the account.

NEW QUESTION # 54
What session parameter can be used to test the integrity of secure views based on the account that is accessing that view?

A. SIMULATED DATA SHARING CONSUMER
B. TEST ACCOUNT ID
C. MIMIC CONSUMER ACCOUNT
D. PRODUCER TEST ACCT

Answer: C

Explanation:
The session parameter MIMIC_CONSUMER_ACCOUNT allows a data provider to test how secure views will appear to a specific consumer account. This ensures the integrity and correctness of secure views before they are shared.
