You are designing a date dimension table in an Azure Synapse Analytics dedicated SQL pool. The date
dimension table will be used by all the fact tables.
Which distribution type should you recommend to minimize data movement?
A replicated table has a full copy of the table available on every Compute node. Queries run fast on replicated tables since joins on replicated tables don't require data movement. Replication requires extra storage, though, and isn't practical for large tables.
Incorrect Answers:
C: A round-robin distributed table distributes table rows evenly across all distributions. The assignment of rows to distributions is random. Unlike hash-distributed tables, rows with equal values are not guaranteed to be assigned to the same distribution.
As a result, the system sometimes needs to invoke a data movement operation to better organize your data before it can resolve a query.
You have an Azure SQL database named DB1. DB1 has a table named Table1 that contains the following columns.
You plan to enable Always Encrypted for Table1.
Which two columns support encryption? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point
