Question 1
Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You have a virtual machine (VM) in Microsoft Azure, which has a 2 terabyte (TB) database. Microsoft SQL Server backups are performed by using Backup to URL. 
You need to provision the storage account for the backups while minimizing costs. 
Which storage option should you use?
  1. Premium P10 disk storage
  2. Premium P20 disk storage
  3. Premium P30 disk storage
  4. Standard locally redundant disk storage
  5. Standard geo-redundant disk storage
  6. Standard zone redundant blob storage
  7. Standard locally redundant blob storage
  8. Standard geo-redundant blob storage
Correct answer: G
Explanation:
A URL specifies a Uniform Resource Identifier (URI) to a unique backup file. The URL is used to provide the location and name of the SQL Server backup file. The URL must point to an actual blob, not just a container. If the blob does not exist, it is created. If an existing blob is specified, BACKUP fails, unless the “WITH FORMAT” option is specified to overwrite the existing backup file in the blob. LOCALLY REDUNDANT STORAGE (LRS) makes multiple synchronous copies of your data within a single datacenter. Incorrect Answers:F: Zone redundant blob storage would be me more expensive as it stores three copies of data across multiple datacenters within or across regions.References:https://msdn.microsoft.com/en-us/library/dn435916.aspxhttps://azure.microsoft.com/en-us/pricing/details/storage/blobs/

Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You have deployed a GS-series virtual machine (VM) in Microsoft Azure. You plan to deploy Microsoft SQL Server. 
You need to deploy a 30 megabyte (MB) database that requires 100 IOPS to be guaranteed while minimizing costs. 
Which storage option should you use?
  1. Premium P10 disk storage
  2. Premium P20 disk storage
  3. Premium P30 disk storage
  4. Standard locally redundant disk storage
  5. Standard geo-redundant disk storage
  6. Standard zone redundant blob storage
  7. Standard locally redundant blob storage
  8. Standard geo-redundant blob storage
Correct answer: A
Explanation:
Premium Storage Disks Limits When you provision a disk against a Premium Storage account, how much input/output operations per second (IOPS) and throughput (bandwidth) it can get depends on the size of the disk. Currently, there are three types of Premium Storage disks: P10, P20, and P30. Each one has specific limits for IOPS and throughput as specified in the following table:  References: https://docs.microsoft.com/en-us/azure/storage/storage-premium-storage

Question 5
You plan to deploy 20 Microsoft Azure SQL Database instances to an elastic pool in Azure to support a batch processing application. 
Two of the databases in the pool reach their peak workload threshold at the same time every day. This leads to inconsistent performance for batch completion. 
You need to ensure that all batches perform consistently. 
What should you do?
  1. Create an In-Memory table.
  2. Increase the storage limit in the pool.
  3. Implement a readable secondary database.
  4. Increase the total number of elastic Database Transaction Units (eDTUs) in the pool.
Correct answer: D
Explanation:
In SQL Database, the relative measure of a database's ability to handle resource demands is expressed in Database Transaction Units (DTUs) for single databases and elastic DTUs (eDTUs) for databases in an elastic pool. A pool is given a set number of eDTUs, for a set price. Within the pool, individual databases are given the flexibility to auto-scale within set parameters. Under heavy load, a database can consume more eDTUs to meet demand. Additional eDTUs can be added to an existing pool with no database downtime. References: https://docs.microsoft.com/en-us/azure/sql-database/sql-database-elastic-pool

Question 6
A company has an on-premises Microsoft SQL Server 2014 environment. The company has a main office in Seattle, and remote offices in Amsterdam and Tokyo. You plan to deploy a Microsoft Azure SQL Database instance to support a new application. You expect to have 100 users from each office. 
In the past, users at remote sites reported issues when they used applications hosted at the Seattle office. 
You need to optimize performance for users running reports while minimizing costs. 
What should you do?
  1. Implement an elastic pool.
  2. Implement a standard database with readable secondaries in Asia and Europe, and then migrate the application.
  3. Implement replication from an on-premises SQL Server database to the Azure SQL Database instance.
  4. Deploy a database from the Premium service tier.
Correct answer: B

Question 7
You administer all the deployments of Microsoft SQL Server 2012 in your company. You have two servers in the same data center that hosts your production database. 
You need to ensure that the database remains available if a catastrophic server failure or a disk failure occurs. 
You also need to maintain transactional consistency of the data across both servers. 
You need to achieve these goals without manual intervention. 
Which configuration should you use?
  1. Two servers configured in a Windows Failover Cluster in the same data center SQL Server configured as a clustered instance
  2. SQL Server that includes an application database configured to perform transactional replication
  3. Two servers configured in the same data centerA primary server configured to perform log-shipping every 10 minutes A backup server configured as a warm standby
  4. Two servers configured in different data centersSQL Server Availability Group configured in Synchronous-Commit Availability Mode One server configured as an Active Secondary
  5. Two servers configured in the same data centerSQL Server Availability Group configured in Asynchronous-Commit Availability Mode One server configured as an Active Secondary
  6. Two servers configured in different data centersSQL Server Availability Group configured in Asynchronous-Commit Availability Mode
  7. SQL Server that includes an application database configured to perform snapshot replication
  8. Two servers configured on the same subnetSQL Server Availability Group configured in Synchronous-Commit Availability Mode
Correct answer: H
Explanation:
Always On availability groups supports two availability modes—asynchronous-commit mode and synchronous-commit mode Synchronous-commit mode emphasizes high availability over performance, at the cost of increased transaction latency. References: https://docs.microsoft.com/en-us/sql/database-engine/availability-groups/windows/availability-modes-always-on-availability-groups#SyncCommitAvMode

References: https://docs.microsoft.com/en-us/sql/database-engine/availability-groups/windows/availability-modes-always-on-availability-groups#SyncCommitAvMode
Question 8
You create an availability group that has replicas named HA/Server01 and HA/Server02. 
Currently, HA/Server01 is the primary replica. 
You have multiple queries that read data and produce reports from the database. 
You need to offload the reporting workload to the secondary replica when HA/Server01 is the primary replica. 
What should you do?
  1. Set the Availability Mode property of HA/Server02 to Asynchronous commit.
  2. Set the Readable Secondary property of HA/Server02 to Read-intent only.
  3. Set the Connections in Primary Role property of HA/Server01 to Allow read/write connections.
  4. Set the Availability Mode property of HA/Server01 to Asynchronous commit.
Correct answer: B
Explanation:
To set up a readable secondary replica, you first create an availability group. Then you add replicas. You can choose either Yes or Read-intent only options.   References: http://msdn.microsoft.com/en-us/library/jj542414.aspx

Question 9
You administer a Microsoft SQL Server 2012 database instance. 
You plan to migrate the database to Windows Azure SQL Database. You verify that all objects contained in the database are compatible with Windows Azure SQL Database. 
You need to ensure that database users and required server logins are migrated to Windows Azure SQL Database. 
What should you do?
  1. Use the copy database wizard
  2. Use the Database Transfer wizard
  3. Use SQL Server Management Studio to deploy the database to Windows Azure SQL Database
  4. Backup the database from the local server and restore it to Windows Azure SQL Database
Correct answer: C
Explanation:
You would need to use either the SQL Server Management Studio or Transact-SQL. References: https://docs.microsoft.com/en-us/azure/sql-database/sql-database-cloud-migrate

Question 10
You administer a Microsoft SQL Server 2012 environment. One of the SQL Server 2012 instances contains a database named Sales. 
You plan to migrate Sales to Windows Azure SQL Database. 
To do so, you need to implement a contained database. 
What should you do? (Each correct answer presents part of the solution. Choose all that apply.)
  1. Set database containment to AZURE.
  2. Enable server property contained database authentication.
  3. Disable server property cross db ownership chaining.
  4. Set database containment to PARTIAL.
  5. Disable server property contained database authentication.
  6. Set database containment to FULL.
Correct answer: BD
Explanation:
A contained database is a database that is isolated from other databases and from the instance of SQL Server that hosts the database. B: In the contained database user model, the login in the master database is not present. Instead, the authentication process occurs at the user database, and the database user in the user database does not have an associated login in the master database.SQL Database and SQL Data Warehouse support Azure Active Directory identities as contained database users. D: The contained database feature is currently available only in a partially contained state. A partially contained database is a contained database that allows the use of uncontained features.References: https://docs.microsoft.com/en-us/sql/relational-databases/databases/contained-databases
