NEW QUESTION # 381
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 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 restore Database1 from Server1 to the Server2 by using the RESTORE Transact-SQL command and the REPLACE option.
Does this meet the goal?
Answer: A
Explanation:
The REPLACE option overrides several important safety checks that restore normally performs. The overridden checks are as follows:
* Restoring over an existing database with a backup taken of another database.
With the REPLACE option, restore allows you to overwrite an existing database with whatever database is in the backup set, even if the specified database name differs from the database name recorded in the backup set. This can result in accidentally overwriting a database by a different database.

NEW QUESTION # 382
You have an Azure subscription.
You need to deploy two instances of SQL Server on Azure virtual machines in a highly available configuration that will use an Always On availability group. The solution must meet the following requirements:
- Minimize how long it takes to fail over.
- Maintain existing connections to the primary replica during a
failover.
What should you do?
Answer: D
Explanation:
To match the on-premises experience for connecting to your availability group listener, deploy your SQL Server VMs to multiple subnets within the same virtual network. Having multiple subnets negates the need for the extra dependency on an Azure Load Balancer, or a distributed network name (DNN) to route your traffic to your listener. ref: https://learn.microsoft.com/en- us/azure/azure-sql/virtual-machines/windows/availability-group-overview?view=azuresql- vm#connectivity
NEW QUESTION # 383
You have an Azure subscription that contains an Azure SQL managed instance named Server1.
You need to ensure the availaibility of Server1 if an Azure region fails.
What should you do?
Answer: D
Explanation:
To protect an Azure SQL Managed Instance from Azure region failures, you should enable zone redundancy for high availability within the region and implement disaster recovery with failover groups to a secondary region. Zone redundancy ensures resilience to zonal outages, while failover groups enable failover to a secondary instance in case of a region-wide outage.
1. Zone Redundancy:
Enable zone redundancy to ensure the managed instance is distributed across multiple availability zones within the same region.
This provides redundancy against hardware and software failures in a single zone, maintaining high availability with up to 99.99% SLA.
You can enable zone redundancy through the Azure portal or PowerShell.
2. Disaster Recovery with Failover Groups:
Create a failover group that includes your primary managed instance and a secondary managed instance in a different region.
The secondary instance serves as a failover target in case of a region-wide outage.
Configure the failover group to replicate data continuously between the instances, ensuring minimal data loss during a failover.

NEW QUESTION # 384
You have SQL Server on an Azure virtual machine that contains a database named DB1.
The database reports a CHECKSUM error.
You need to recover the database.
How should you complete the statements? To answer, select the appropriate options in the answer area.
NOTE:Each correct selection is worth one point.
Answer:
Explanation:
Explanation
Box 1: SINGLE_USER
The specified database must be in single-user mode to use one of the following repair options.
Box 2: REPAIR_ALLOW_DATA_LOSS
REPAIR_ALLOW_DATA_LOSS tries to repair all reported errors. These repairs can cause some data loss.
Note: The REPAIR_ALLOW_DATA_LOSS option is a supported feature but it may not always be the best option for bringing a database to a physically consistent state. If successful, the REPAIR_ALLOW_DATA_LOSS option may result in some data loss. In fact, it may result in more data lost than if a user were to restore the database from the last known good backup.
