Question:20

You develop a Web App on a tier D1 app service plan.
You notice that page load times increase during periods of peak traffic.
You want to implement automatic scaling when CPU load is above 80 percent. Your solution must minimize costs.
What should you do first?

  • A. Enable autoscaling on the Web App.
  • B. Switch to the Premium App Service tier plan.
  • C. Switch to the Standard App Service tier plan.
  • D. Switch to the Azure App Services consumption plan.
Correct Answer: C

Configure the web app to the Standard App Service Tier. The Standard tier supports auto-scaling, and we should minimize the cost. We can then enable autoscaling on the web app, add a scale rule and add a Scale condition.

Question:21

Your company's Azure subscription includes an Azure Log Analytics workspace.
Your company has a hundred on-premises servers that run either Windows Server 2012 R2 or Windows Server 2016, and is linked to the Azure Log Analytics workspace. The Azure Log Analytics workspace is set up to gather performance counters associated with security from these linked servers.
You must configure alerts based on the information gathered by the Azure Log Analytics workspace.
You have to make sure that alert rules allow for dimensions, and that alert creation time should be kept to a minimum. Furthermore, a single alert notification must be created when the alert is created and when the alert is resolved.
You need to make use of the necessary signal type when creating the alert rules.
Which of the following is the option you should use?

  • A. The Activity log signal type.
  • B. The Application Log signal type.
  • C. The Metric signal type.
  • D. The Audit Log signal type.
Correct Answer: C 

Metric alerts in Azure Monitor provide a way to get notified when one of your metrics cross a threshold. Metric alerts work on a range of multi-dimensional platform metrics, custom metrics, Application Insights standard and custom metrics.
Note: Signals are emitted by the target resource and can be of several types. Metric, Activity log, Application Insights, and Log.

Question:22

You are developing a .NET Core MVC application that allows customers to research independent holiday accommodation providers.
You want to implement Azure Search to allow the application to search the index by using various criteria to locate documents related to accommodation.
You want the application to allow customers to search the index by using regular expressions.
What should you do?

  • A. Configure the SearchMode property of the SearchParameters class.
  • B. Configure the QueryType property of the SearchParameters class.
  • C. Configure the Facets property of the SearchParameters class.
  • D. Configure the Filter property of the SearchParameters class.
Correct Answer: B

The SearchParameters.QueryType Property gets or sets a value that specifies the syntax of the search query. The default is 'simple'. Use 'full' if your query uses the Lucene query syntax.
You can write queries against Azure Search based on the rich Lucene Query Parser syntax for specialized query forms: wildcard, fuzzy search, proximity search, regular expressions are a few examples.

Question:30

DRAG DROP -
You are a developer for a company that provides a bookings management service in the tourism industry. You are implementing Azure Search for the tour agencies listed in your company's solution.
You create the index in Azure Search. You now need to use the Azure Search .NET SDK to import the relevant data into the Azure Search service.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions from left to right and arrange them in the correct order.
Select and Place:

 Answer: 

1. The index needs to be populated. To do this, we will need a SearchIndexClient. There are two ways to obtain one: by constructing it, or by calling
Indexes.GetClient on the SearchServiceClient. Here we will use the first method.
2. Create the indexBatch with the documents
Something like:
var hotels = new Hotel[];
{
new Hotel()
{
HotelId = "3",
BaseRate = 129.99,
Description = "Close to town hall and the river"
}
};
ג€¦
var batch = IndexBatch.Upload(hotels);
3. The next step is to populate the newly-created index
Example:
var batch = IndexBatch.Upload(hotels);
try
{
indexClient.Documents.Index(batch);
}
