NEW QUESTION 17
You have 50 Azure SQL databases.
You need to notify the database owner when the database settings, such as the database size and pricing tier, are modified in Azure.
What should you do?
- A. For the database, create a diagnostic setting that has the InstanceAndAppAdvanced metric enabled.
- B. Create an alert rule that uses an Activity Log signal type.
- C. Create an alert rule that uses a Metric signal type.
- D. Create a diagnostic setting for the activity log that has the Security log enabled.
Answer: B
Explanation:
Activity log events - An alert can trigger on every event, or, only when a certain number of events occur.
Incorrect Answers:
C: Metric values - The alert triggers when the value of a specified metric crosses a threshold you assign in either direction. That is, it triggers both when the condition is first met and then afterwards when that condition is no longer being met.

NEW QUESTION 19
You have a new Azure SQL database. The database contains a column that stores confidential information.
You need to track each time values from the column are returned in a query. The tracking information must be stored for 365 days from the date the query was executed.
Which three actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
- A. Turn on Azure Advanced Threat Protection (ATP).
- B. Turn on Advanced Data Security for the Azure SQL server.
- C. Add extended properties to the column.
- D. Apply sensitivity labels named Highly Confidential to the column.
- E. Turn on auditing and write audit logs to an Azure Storage account.
Answer: B,D,E
Explanation:
C: Advanced Data Security (ADS) is a unified package for advanced SQL security capabilities. ADS is available for Azure SQL Database, Azure SQL Managed Instance, and Azure Synapse Analytics. It includes functionality for discovering and classifying sensitive data D: You can apply sensitivity-classification labels persistently to columns by using new metadata attributes that have been added to the SQL Server database engine. This metadata can then be used for advanced, sensitivity-based auditing and protection scenarios.
A: An important aspect of the information-protection paradigm is the ability to monitor access to sensitive data. Azure SQL Auditing has been enhanced to include a new field in the audit log called data_sensitivity_information. This field logs the sensitivity classifications (labels) of the data that was returned by a query. Here's an example:

You have a version-8.0 Azure Database for MySQL database.
You need to identify which database queries consume the most resources.
Which tool should you use?
- A. Query Store
- B. Alerts
- C. Query Performance Insight
- D. Metrics
Answer: A
Explanation:
Section: [none]
Explanation:
The Query Store feature in Azure Database for MySQL provides a way to track query performance over time.
Query Store simplifies performance troubleshooting by helping you quickly find the longest running and most
resource-intensive queries. Query Store automatically captures a history of queries and runtime statistics, and it
retains them for your review. It separates data by time windows so that you can see database usage patterns.
Data for all users, databases, and queries is stored in the mysql schema database in the Azure Database for
MySQL instance.

You have an Azure virtual machine named VM1 on a virtual network named VNet1. Outbound traffic from VM1 to the internet is blocked.
You have an Azure SQL database named SqlDb1 on a logical server named SqlSrv1.
You need to implement connectivity between VM1 and SqlDb1 to meet the following requirements:
Ensure that all traffic to the public endpoint of SqlSrv1 is blocked.
Minimize the possibility of VM1 exfiltrating data stored in SqlDb1.

What should you create on VNet1?
- A. a VPN gateway
- B. an ExpressRoute gateway
- C. a private link
- D. a service endpoint
Answer: C
Explanation:
Azure Private Link enables you to access Azure PaaS Services (for example, Azure Storage and SQL Database) and Azure hosted customer-owned/partner services over a private endpoint in your virtual network.
Traffic between your virtual network and the service travels the Microsoft backbone network. Exposing your service to the public internet is no longer necessary.

NEW QUESTION 35
You have an Azure SQL database that contains a table named factSales. FactSales contains the columns shown in the following table.
FactSales has 6 billion rows and is loaded nightly by using a batch process.
Which type of compression provides the greatest space reduction for the database?
- A. columnstore compression
- B. page compression
- C. columnstore archival compression
- D. row compression
Answer: C
Explanation:
Columnstore tables and indexes are always stored with columnstore compression. You can further reduce the size of columnstore data by configuring an additional compression called archival compression.
Note: Columnstore - The columnstore index is also logically organized as a table with rows and columns, but the data is physically stored in a column-wise data format.
Incorrect Answers:
B: Rowstore - The rowstore index is the traditional style that has been around since the initial release of SQL Server.
For rowstore tables and indexes, use the data compression feature to help reduce the size of the database.

NEW QUESTION 37
You are planning disaster recovery for the failover group of an Azure SQL Database managed instance.
Your company's SLA requires that the database in the failover group become available as quickly as possible if
a major outage occurs.
You set the Read/Write failover policy to Automatic.
What are two results of the configuration? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
- A. In the event of a datacenter or Azure regional outage, the databases will fail over automatically.
- B. In the event of an outage, the databases in the primary instance will fail over immediately.
- C. In the event of an outage, you can selectively fail over individual databases.
- D. In the event of an outage, the minimum delay for the databases to fail over in the primary instance will be
one hour. - E. In the event of an outage, you can set a different grace period to fail over each database.
Answer: A,D
Explanation:
Section: [none]
Explanation:
A: Auto-failover groups allow you to manage replication and failover of a group of databases on a server or all
databases in a managed instance to another region.
E: Because verification of the scale of the outage and how quickly it can be mitigated involves human actions
by the operations team, the grace period cannot be set below one hour. This limitation applies to all databases
in the failover group regardless of their data synchronization state.
Incorrect Answers:
C: individual SQL Managed Instance databases cannot be added to or removed from a failover group.
