Explanation:
Box 1: Node majority with witness
As a general rule when you configure a quorum, the voting elements in the cluster should be an odd number.
Therefore, if the cluster contains an even number of voting nodes, you should configure a disk witness or a file
share witness.
Note: Mode: Node majority with witness (disk or file share)
Nodes have votes. In addition, a quorum witness has a vote. The cluster quorum is the majority of voting nodes
in the active cluster membership plus a witness vote. A quorum witness can be a designated disk witness or a
designated file share witness.
Box 2: Azure Standard Load Balancer
Microsoft guarantees that a Load Balanced Endpoint using Azure Standard Load Balancer, serving two or more
Healthy Virtual Machine Instances, will be available 99.99% of the time.
Scenario: Business Requirements
Litware identifies business requirements include: meet an SLA of 99.99% availability for all Azure deployments.
Incorrect Aswers:
Basic Balancer: No SLA is provided for Basic Load Balancer.
Note: There are two main options for setting up your listener: external (public) or internal. The external (public)
listener uses an internet facing load balancer and is associated with a public Virtual IP (VIP) that is accessible
over the internet. An internal listener uses an internal load balancer and only supports clients within the same
Virtual Network.

You have two Azure SQL Database servers named Server1 and Server2. Each server contains an Azure SQL database named Database1.
You need to restore Database1 from Server1 to Server2. The solution must replace the existing Database1 on Server2.
Solution: You run the Remove-AzSqlDatabase PowerShell cmdlet for Database1 on Server2. You run the Restore-AzSqlDatabase PowerShell cmdlet for Database1 on Server2.
Does this meet the goal?
- A. No
- B. Yes
Answer: A
Explanation:
Instead restore Database1 from Server1 to the Server2 by using the RESTORE Transact-SQL command and the REPLACE option.
Note: REPLACE should be used rarely and only after careful consideration. Restore normally prevents accidentally overwriting a database with a different database. If the database specified in a RESTORE statement already exists on the current server and the specified database family GUID differs from the database family GUID recorded in the backup set, the database is not restored. This is an important safeguard.

You have an Azure Data Lake Storage account that contains a staging zone.
You need to design a daily process to ingest incremental data from the staging zone, transform the data by executing an R script, and then insert the transformed data into a data warehouse in Azure Synapse Analytics.
Solution: You use an Azure Data Factory schedule trigger to execute a pipeline that executes mapping data flow, and then inserts the data into the data warehouse.
Does this meet the goal?
- A. No
- B. Yes
Answer: A
Explanation:
If you need to transform data in a way that is not supported by Data Factory, you can create a custom activity, not a mapping flow,5 with your own data processing logic and use the activity in the pipeline. You can create a custom activity to run R scripts on your HDInsight cluster with R installed.

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 Data Flush Interval
- B. Double the value of Data Flush interval
- C. Decrease by half the value of Statistics Collection interval
- D. Double the value of Statistics Collection Interval
Answer: A
Explanation:
Section: [none]
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.
Incorrect Answers:
C: Statistics Collection Interval: Defines the level of granularity for the collected runtime statistic, expressed in minutes. The default is 60 minutes. Consider using a lower value if you require finer granularity or less time to detect and mitigate issues. Keep in mind that the value directly affects the size of Query Store data.
