   a. They appear in a column called “_corrupt_record”
   b. They get deleted automatically
   c. They throw an exception and exit the read operation
8. Why do you chain methods:
   (operations) myDataFrameDF.select().filter().groupBy()?
   a. to get accurate results
   b. to avoid the creation of temporary DataFrames as local variables
   c. it is the only way to do it
9. Authentication for an Event hub is defined with a combination of an Event Publisher and which other components?

    a. Diagnose and solve problems
    b. Azure monitor
    c. Network performance monitor

Check the correct answers here:

1. b.
   Explanation: High Availability duplicates customers’ content for redundancy and meeting Service Level Agreements in Azure.
2. b.
   Explanation: Azure Cosmos DB is a globally distributed, multi-model database that can offer sub-second query performance.
3. a.
   Explanation: Azure Data Factory (ADF) is a cloud integration service that orchestrates the movement of data between various data stores.
4. a.
   Explanation: Replication policy is a characteristic of a storage account. Every member of the storage account must use the same policy. If you need some data to use the geo-replication strategy and other data to use the local replication strategy, then you will need two storage accounts
5. b.
   Explanation: If you want to enable the best performance for Analytical Workloads in Data Lake Storage Gen 2, then on the Advanced tab of the Storage Account creation set the Hierarchical Namespace to enabled.
6. a.
   Explanation: JDBC. JDBC stands for Java Database Connectivity and is a Java API for connecting to databases such as MySQL, Hive, and other data stores. ODBC is not an option and the REST API Layer is not available
7. a.
   Explanation: They appear in a column called “_corrupt_record”. They do not get deleted automatically or throw an exception and exit the read operation
8. b.
   Explanation: To avoid the creation of temporary DataFrames as local variables. You could have written the above as – tempDF1 = myDataFrameDF.select(), tempDF2 = tempDF1.filter() and then tempDF2.groupBy(). This is syntatically equivalent, but, notice how you now have extra local variables.
9. b.
   Explanation: A Shared Access Signature in combination with an Event Publisher is used to define authentication for an event hub.
10. a.
    Explanation: Diagnose and solve problems. Diagnose and solve problems can quickly show you the service availability. Azure Monitor allows you in collecting, analyzing, and acting on telemetry from both cloud and on-premises environments. A network performance monitor measures the performance and reachability of the networks that you have configured.
