NEW QUESTION 80
You receive numerous alerts from Azure Monitor for an Azure SQL database.
You need to reduce the number of alerts. You must only receive alerts if there is a significant change in usage patterns for an extended period.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

• A. Set Threshold Sensitivity to Low
• B. Set the Alert logic threshold to Dynamic
• C. Set the Alert logic threshold to Static
• D. Set Threshold Sensitivity to High
• E. Set Force Plan to On

Answer: A,B

Explanation:
B: Dynamic Thresholds continuously learns the data of the metric series and tries to model it using a set of algorithms and methods. It detects patterns in the data such as seasonality (Hourly / Daily / Weekly), and is able to handle noisy metrics (such as machine CPU or memory) as well as metrics with low dispersion (such as availability and error rate).
D: Alert threshold sensitivity is a high-level concept that controls the amount of deviation from metric behavior required to trigger an alert.
Low - The thresholds will be loose with more distance from metric series pattern. An alert rule will only trigger on large deviations, resulting in fewer alerts.
Incorrect Answers:
A: High - The thresholds will be tight and close to the metric series pattern. An alert rule will be triggered on the smallest deviation, resulting in more alerts.

NEW QUESTION 83
You have an Azure SQL database named DB1.
You need to ensure that DB1 will support automatic failover without data loss if a datacenter fails. The solution
must minimize costs.
Which deployment option and pricing tier should you configure?

• A. Azure SQL Database Standard
• B. Azure SQL Database serverless
• C. Azure SQL Database managed instance Business Critical
• D. Azure SQL Database Premium

Answer: D

Explanation:
Section: [none]
Explanation:
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). The routing to a specific gateway ring is
controlled by Azure Traffic Manager (ATM). Because the zone redundant configuration in the Premium or
Business Critical service tiers does not create additional database redundancy, you can enable it at no extra
cost. By selecting a zone redundant configuration, you can make your Premium or Business Critical databases
resilient to a much larger set of failures, including catastrophic datacenter outages, without any changes to the
application logic. You can also convert any existing Premium or Business Critical databases or pools to the
zone redundant configuration.
Incorrect Answers:
C. This feature is not available in SQL Managed Instance.

Overview
General Overview
Contoso, Ltd. is a financial data company that has 100 employees. The company delivers financial data to customers.
Physical Locations
Contoso has a datacenter in Los Angeles and an Azure subscription. All Azure resources are in the US West 2 Azure region. Contoso has a 10-Gb ExpressRoute connection to Azure.
The company has customers worldwide.
Existing Environment
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 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.

 

NEW QUESTION 85
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 Business Critical service tier and Availability Zones.
Does this meet the goal?

• A. No
• B. Yes

Answer: B

Explanation:
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 86
You deploy a database to an Azure SQL Database managed instance.
You need to prevent read queries from blocking queries that are trying to write to the database.
Which database option should set?

• A. Delayed Durability to Forced
• B. READ_COMMITTED_SNAPSHOTto ON
• C. PARAMETERIZATIONto FORCED
• D. PARAMETERIZATIONto SIMPLE

Answer: B

Explanation:
In SQL Server, you can also minimize locking contention while protecting transactions from dirty reads of uncommitted data modifications using either:
* The READ COMMITTED isolation level with the READ_COMMITTED_SNAPSHOT database option set to ON.
* The SNAPSHOT isolation level.
If READ_COMMITTED_SNAPSHOT is set to ON (the default on SQL Azure Database), the Database Engine uses row versioning to present each statement with a transactionally consistent snapshot of the data as it existed at the start of the statement. Locks are not used to protect the data from updates by other transactions.
Incorrect Answers:
A: When the PARAMETERIZATION database option is set to SIMPLE, the SQL Server query optimizer may choose to parameterize the queries. This means that any literal values that are contained in a query are substituted with parameters. This process is referred to as simple parameterization. When SIMPLE parameterization is in effect, you cannot control which queries are parameterized and which queries are not.
B: You can specify that all queries in a database be parameterized by setting the PARAMETERIZATION database option to FORCED. This process is referred to as forced parameterization.
C: Delayed transaction durability is accomplished using asynchronous log writes to disk. Transaction log records are kept in a buffer and written to disk when the buffer fills or a buffer flushing event takes place.
Delayed transaction durability reduces both latency and contention within the system.
Some of the cases in which you could benefit from using delayed transaction durability are:
* You can tolerate some data loss.
* You are experiencing a bottleneck on transaction log writes.
* Your workloads have a high contention rate.
