Question 79
Correct answer: Question 79

Explanation:

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

New records are inserted with TableOperation.insert. Old records are not updated.

To update old records TableOperation.insertOrReplace should be used instead.

Box 3: No

Box 4: Yes
