• B. Not Mastered

Answer: A

Explanation:
Box 1: memory-optimized table
In-Memory OLTP can provide great performance benefits for transaction processing, data ingestion, and transient data scenarios.
Box 2: materialized view
To support efficient querying, a common solution is to generate, in advance, a view that materializes the data in a format suited to the required results set. The Materialized View pattern describes generating prepopulated views of data in environments where the source data isn't in a suitable format for querying, where generating a suitable query is difficult, or where query performance is poor due to the nature of the data or the data store.
These materialized views, which only contain data required by a query, allow applications to quickly obtain the information they need. In addition to joining tables or combining data entities, materialized views can include the current values of calculated columns or data items, the results of combining values or executing transformations on the data items, and values specified as part of the query. A materialized view can even be optimized for just a single query.

NEW QUESTION 10

A company plans to use Azure Storage for file storage purposes. Compliance rules require: A single storage account to store all operations including reads, writes and deletes
Retention of an on-premises copy of historical operations You need to configure the storage account.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

• A. Configure the storage account to log read, write and delete operations for service type Blob
• B. Use the AzCopy tool to download log data from $logs/blob
• C. Configure the storage account to log read, write and delete operations for service-type table
• D. Use the storage client to download log data from $logs/table
• E. Configure the storage account to log read, write and delete operations for service type queue

Answer: AB

Explanation:
Storage Logging logs request data in a set of blobs in a blob container named $logs in your storage account. This container does not show up if you list all the blob containers in your account but you can see its contents if you access it directly.
To view and analyze your log data, you should download the blobs that contain the log data you are interested in to a local machine. Many storage-browsing tools enable you to download blobs from your storage account; you can also use the Azure Storage team provided command-line Azure Copy Tool (AzCopy) to download your log data.

NEW QUESTION 17

You plan to use Microsoft Azure SQL Database instances with strict user access control. A user object must:
Move with the database if it is run elsewhere
Be able to create additional users
You need to create the user object with correct permissions.
Which two Transact-SQL commands should you run? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

• A. ALTER LOGIN Mary WITH PASSWORD = 'strong_password';
• B. CREATE LOGIN Mary WITH PASSWORD = 'strong_password';
• C. ALTER ROLE db_owner ADD MEMBER Mary;
• D. CREATE USER Mary WITH PASSWORD = 'strong_password';
• E. GRANT ALTER ANY USER TO Mary;

Answer: CD

Explanation:
C: ALTER ROLE adds or removes members to or from a database role, or changes the name of a user-defined database role.
Members of the db_owner fixed database role can perform all configuration and maintenance activities on the database, and can also drop the database in SQL Server.
D: CREATE USER adds a user to the current database.
Note: Logins are created at the server level, while users are created at the database level. In other words, a login allows you to connect to the SQL Server service (also called an instance), and permissions inside the database are granted to the database users, not the logins. The logins will be assigned to server roles (for example, serveradmin) and the database users will be assigned to roles within that database (eg. db_datareader, db_bckupoperator).
