Suggested Answer: 
    

Box 1: Yes -
Create a table.
A CloudTableClient object lets you get reference objects for tables and entities. The following code creates a CloudTableClient object and uses it to create a new
CloudTable object, which represents a table
// Retrieve storage account from connection-string.
CloudStorageAccount storageAccount =
CloudStorageAccount.parse(storageConnectionString);
// Create the table client.
CloudTableClient tableClient = storageAccount.createCloudTableClient();
// Create the table if it doesn't exist.
String tableName = "people";
CloudTable cloudTable = tableClient.getTableReference(tableName); cloudTable.createIfNotExists();
Box 2: No -
