NEW QUESTION 55
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. No
- B. Yes
Answer: A
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).

You have SQL Server on an Azure virtual machine that contains a database named DB1.
You have an application that queries DB1 to generate a sales report.
You need to see the parameter values from the last time the query was executed.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
- A. Enable PARAMETER_SNIFFING in DB1
- B. Enable Last_Query_Plan_Stats in the master database
- C. Enable Lightweight_Query_Profiling in the master database
- D. Enable Lightweight_Query_Profiling in DB1
- E. Enable Last_Query_Plan_Stats in DB1
Answer: B,E
Explanation:
Last_Query_Plan_Stats allows you to enable or disable collection of the last query plan statistics (equivalent to an actual execution plan) in sys.dm_exec_query_plan_stats.
Lightweight profiling can be disabled at the database level using the LIGHTWEIGHT_QUERY_PROFILING database scoped configuration: ALTER DATABASE SCOPED CONFIGURATION SET LIGHTWEIGHT_QUERY_PROFILING = OFF;.
Incorrect Answers:
E: Parameter sensitivity, also known as "parameter sniffing", refers to a process whereby SQL Server "sniffs" the current parameter values during compilation or recompilation, and passes it along to the Query Optimizer so that they can be used to generate potentially more efficient query execution plans.
Parameter values are sniffed during compilation or recompilation for the following types of batches:
* Stored procedures
* Queries submitted via sp_executesql
* Prepared queries

You have an on-premises Microsoft SQL Server 2016 server named Server1 that contains a database named DB1.
You need to perform an online migration of DB1 to an Azure SQL Database managed instance by using Azure Database Migration Service.
How should you configure the backup of DB1? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: Full and log backups only
Make sure to take every backup on a separate backup media (backup files). Azure Database Migration Service doesn't support backups that are appended to a single backup file. Take full backup and log backups to separate backup files.
Box 2: WITH CHECKSUM
Azure Database Migration Service uses the backup and restore method to migrate your on-premises databases to SQL Managed Instance. Azure Database Migration Service only supports backups created using checksum.
Incorrect Answers:
NOINIT Indicates that the backup set is appended to the specified media set, preserving existing backup sets. If a media password is defined for the media set, the password must be supplied. NOINIT is the default.
UNLOAD
Specifies that the tape is automatically rewound and unloaded when the backup is finished. UNLOAD is the default when a session begins.

Overview
Existing Environment
Contoso, Ltd. is a financial data company that has 100 employees. The company delivers financial data to
customers.
Active Directory
Contoso has a hybrid Azure Active Directory (Azure AD) deployment that syncs to on-premises Active
Directory.
Database Environment
Contoso has SQL Server 2017 on Azure virtual machines shown in the following table.
SQL1 and SQL2 are in an Always On availability group and are actively queried. SQL3 runs jobs, provides
historical data, and handles the delivery of data to customers.
The on-premises datacenter contains a PostgreSQL server that has a 50-TB database.
Current Business Model
Contoso uses Microsoft SQL Server Integration Services (SSIS) to create flat files for customers. The
customers receive the files by using FTP.
Requirements
Planned Changes
Contoso plans to move to a model in which they deliver data to customer databases that run as platform as a
service (PaaS) offerings. When a customer establishes a service agreement with Contoso, a separate resource
group that contains an Azure SQL database will be provisioned for the customer. The database will have a
complete copy of the financial data. The data to which each customer will have access will depend on the
service agreement tier. The customers can change tiers by changing their service agreement.
The estimated size of each PaaS database is 1 TB.
Contoso plans to implement the following changes:
* Move the PostgreSQL database to Azure Database for PostgreSQL during the next six months.
* Upgrade SQL1, SQL2, and SQL3 to SQL Server 2019 during the next few months.
* Start onboarding customers to the new PaaS solution within six months.
Business Goals
Contoso identifies the following business requirements:
* Use built-in Azure features whenever possible.
* Minimize development effort whenever possible.
* Minimize the compute costs of the PaaS solutions.
* Provide all the customers with their own copy of the database by using the PaaS solution.
* Provide the customers with different table and row access based on the customer's service agreement.
* In the event of an Azure regional outage, ensure that the customers can access the PaaS solution with
minimal downtime. The solution must provide automatic failover.
* Ensure that users of the PaaS solution can create their own database objects but he prevented from
modifying any of the existing database objects supplied by Contoso.
Technical Requirements
Contoso identifies the following technical requirements:
* Users of the PaaS solution must be able to sign in by using their own corporate Azure AD credentials or
have Azure AD credentials supplied to them by Contoso. The solution must avoid using the internal Azure
AD of Contoso to minimize guest users.
* All customers must have their own resource group, Azure SQL server, and Azure SQL database. The
deployment of resources for each customer must be done in a consistent fashion.
* Users must be able to review the queries issued against the PaaS databases and identify any new objects
created.
* Downtime during the PostgreSQL database migration must be minimized.
Monitoring Requirements
Contoso identifies the following monitoring requirements:
* Notify administrators when a PaaS database has a higher than average CPU usage.
* Use a single dashboard to review security and audit data for all the PaaS databases.
* Use a single dashboard to monitor query performance and bottlenecks across all the PaaS databases.
* Monitor the PaaS databases to identify poorly performing queries and resolve query performance issues
automatically whenever possible.
PaaS Prototype
During prototyping of the PaaS solution in Azure, you record the compute utilization of a customer's Azure SQL
database as shown in the following exhibit.
Role Assignments

Contoso has a hybrid Azure Active Directory (Azure AD) deployment that syncs to on-premises Active Directory.
Database Environment
Contoso has SQL Server 2017 on Azure virtual machines shown in the following table.
SQL1 and SQL2 are in an Always On availability group and are actively queried. SQL3 runs jobs, provides historical data, and handles the delivery of data to customers.
The on-premises datacenter contains a PostgreSQL server that has a 50-TB database.
Current Business Model
Contoso uses Microsoft SQL Server Integration Services (SSIS) to create flat files for customers. The customers receive the files by using FTP.
Requirements
Planned Changes
Contoso plans to move to a model in which they deliver data to customer databases that run as platform as a service (PaaS) offerings. When a customer establishes a service agreement with Contoso, a separate resource group that contains an Azure SQL database will be provisioned for the customer. The database will have a complete copy of the financial data. The data to which each customer will have access will depend on the service agreement tier. The customers can change tiers by changing their service agreement.
The estimated size of each PaaS database is 1 TB.
Contoso plans to implement the following changes:
* Move the PostgreSQL database to Azure Database for PostgreSQL during the next six months.
* Upgrade SQL1, SQL2, and SQL3 to SQL Server 2019 during the next few months.
* Start onboarding customers to the new PaaS solution within six months.
Business Goals
Contoso identifies the following business requirements:
* Use built-in Azure features whenever possible.
* Minimize development effort whenever possible.
* Minimize the compute costs of the PaaS solutions.
* Provide all the customers with their own copy of the database by using the PaaS solution.
* Provide the customers with different table and row access based on the customer's service agreement.
* In the event of an Azure regional outage, ensure that the customers can access the PaaS solution with minimal downtime. The solution must provide automatic failover.
* Ensure that users of the PaaS solution can create their own database objects but be prevented from modifying any of the existing database objects supplied by Contoso.
Technical Requirements
Contoso identifies the following technical requirements:
* Users of the PaaS solution must be able to sign in by using their own corporate Azure AD credentials or have Azure AD credentials supplied to them by Contoso. The solution must avoid using the internal Azure AD of Contoso to minimize guest users.
* All customers must have their own resource group, Azure SQL server, and Azure SQL database. The deployment of resources for each customer must be done in a consistent fashion.
* Users must be able to review the queries issued against the PaaS databases and identify any new objects created.
* Downtime during the PostgreSQL database migration must be minimized.
Monitoring Requirements
Contoso identifies the following monitoring requirements:
* Notify administrators when a PaaS database has a higher than average CPU usage.
* Use a single dashboard to review security and audit data for all the PaaS databases.
* Use a single dashboard to monitor query performance and bottlenecks across all the PaaS databases.
* Monitor the PaaS databases to identify poorly performing queries and resolve query performance issues automatically whenever possible.
PaaS Prototype
During prototyping of the PaaS solution in Azure, you record the compute utilization of a customer's Azure SQL database as shown in the following exhibit.
Role Assignments
For each customer's Azure SQL Database server, you plan to assign the roles shown in the following exhibit.

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. No
- B. Yes
Answer: A
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).

NEW QUESTION 70
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.
D18912E1457D5D1DDCBD40AB3BF70D5D
What should you create on VNet1?
- A. a VPN gateway
- B. a private link
- C. an ExpressRoute gateway
- D. a service endpoint
Answer: B
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.

You have an Azure Databricks resource.
You need to log actions that relate to changes in compute for the Databricks resource.
Which Databricks services should you log?
- A. DBFS
- B. SSH
- C. workspace
- D. clusters
- E. jobs
Answer: C
Explanation:
Section: [none]
Explanation:
Cloud Provider Infrastructure Logs.
Databricks logging allows security and admin teams to demonstrate conformance to data governance standards within or from a Databricks workspace. Customers, especially in the regulated industries, also need records on activities like:
* User access control to cloud data storage
* Cloud Identity and Access Management roles
* User access to cloud network and compute
Azure Databricks offers three distinct workloads on several VM Instances tailored for your data analytics workflow-the Jobs Compute and Jobs Light Compute workloads make it easy for data engineers to build and execute jobs, and the All-Purpose Compute workload makes it easy for data scientists to explore, visualize, manipulate, and share data and insights interactively.
