Box 1: CREATE EXTERNAL TABLE
An external table points to data located in Hadoop, Azure Storage blob, or Azure Data Lake Storage. External tables are used to read data from files or write data to files in Azure Storage. With Synapse SQL, you can use external tables to read external data using dedicated SQL pool or serverless SQL pool.
Syntax:
CREATE EXTERNAL TABLE { database_name.schema_name.table_name | schema_name.table_name | table_name } ( <column_definition> [ ,...n ] ) WITH ( LOCATION = 'folder_or_filepath', DATA_SOURCE = external_data_source_name, FILE_FORMAT = external_file_format_name Box 2. OPENROWSET When using serverless SQL pool, CETAS is used to create an external table and export query results to Azure Storage Blob or Azure Data Lake Storage Gen2.

NEW QUESTION # 141
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. ROUND_ROBIN
- B. HASH
- C. REPLICATE
Answer: C
Explanation:
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.

NEW QUESTION # 143
You have an Azure SQL database named sqldb1.
You need to minimize the possibility of Query Store transitioning to a read-only state.
What should you do?
- A. Decrease by half the value of Statistics Collection interval
- B. Decrease by half the value of Data Flush Interval
- C. Double the value of Data Flush interval
- D. Double the value of Statistics Collection Interval
Answer: B
Explanation:
Explanation
The Max Size (MB) limit isn't strictly enforced. Storage size is checked only when Query Store writes data to disk. This interval is set by the Data Flush Interval (Minutes) option. If Query Store has breached the maximum size limit between storage size checks, it transitions to read-only mode.

NEW QUESTION # 144
You have an Azure Stream Analytics job.
You need to ensure that the job has enough streaming units provisioned.
You configure monitoring of the SU % Utilization metric.
Which two additional metrics should you monitor? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
- A. Watermark Delay
- B. Backlogged Input Events
- C. Out of order Events
- D. Function Events
- E. Late Input Events
Answer: A,B
Explanation:
Explanation
To react to increased workloads and increase streaming units, consider setting an alert of 80% on the SU Utilization metric. Also, you can use watermark delay and backlogged events metrics to see if there is an impact.
Note: Backlogged Input Events: Number of input events that are backlogged. A non-zero value for this metric implies that your job isn't able to keep up with the number of incoming events. If this value is slowly increasing or consistently non-zero, you should scale out your job, by increasing the SUs.

Note: This question is part of a series of questions that present the same scenario. Each question in
the series contains a unique solution that might meet the stated goals. Some question sets might have
more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these
questions will not appear in the review screen.
You have an Azure SQL database named Sales.
You need to implement disaster recovery for Sales to meet the following requirements:
* During normal operations, provide at least two readable copies of Sales.
* Ensure that Sales remains available if a datacenter fails.
Solution: You deploy an Azure SQL database that uses the General Purpose service tier and failover groups.
Does this meet the goal?
- A. Yes
- B. No
Answer: B
Explanation:
Section: [none]
Explanation:
Instead deploy an Azure SQL database that uses the Business Critical service tier and Availability Zones.
Note: Premium and Business Critical service tiers leverage the Premium availability model, which integrates
compute resources (sqlservr.exe process) and storage (locally attached SSD) on a single node. High
availability is achieved by replicating both compute and storage to additional nodes creating a three to four-
node cluster.
By default, the cluster of nodes for the premium availability model is created in the same datacenter. With the
introduction of Azure Availability Zones, SQL Database can place different replicas of the Business Critical
database to different availability zones in the same region. To eliminate a single point of failure, the control ring
is also duplicated across multiple zones as three gateway rings (GW).
