AZ-400 Test 2

Question 1

You're in charge of an Azure web app that powers an e-commerce site.
When the web app's usage patterns deviate from regular, you'll need to boost the logging level. The solution must have a low administrative cost.
Which two resources do you think you should include in your solution? Each accurate response reveals a piece of the solution.

Accepted Answer

an Azure Automation runbook

Answer

To automatically boost the logging level when web app usage patterns deviate, an Azure Monitor alert with a dynamic threshold is ideal. This alert type automatically learns normal behavior and triggers on anomalies, minimizing administrative overhead. When the alert fires, it can then trigger an Azure Automation runbook, which can execute a script to programmatically adjust the web app's logging level, providing an automated and low-cost solution.

Question 2

In Azure, you have a Microsoft ASP.NET Core web app that is accessed from all over the world.
Once every five minutes, run a URL ping test and create an alert if the web app is inaccessible in particular Azure regions. The solution should take as little time as possible to build.
What are your options?

Accepted Answer

Create an Azure Application Insights availability test and alert

Answer

To run a URL ping test every five minutes and alert if a web app is inaccessible in specific Azure regions with minimal build time, creating an Azure Application Insights availability test and alert is the best option. Application Insights allows you to configure multi-step web tests or simple URL ping tests from various global locations. These tests automatically monitor your web app's availability and performance, and you can easily set up alerts to notify you of any failures in specific regions.

Question 3

For monitoring, you use Azure SQL Database Intelligent Insights and Azure Application Insights.
Ad-hoc searches against the monitoring data are required.
What is the best query language to use?

Accepted Answer

Kusto Query Language (KQL)

Answer

Both Azure SQL Database Intelligent Insights and Azure Application Insights send their monitoring data to Azure Monitor Logs, which uses a Log Analytics workspace. The Kusto Query Language (KQL) is the powerful and flexible query language used within Azure Monitor Logs for performing ad-hoc searches, complex analysis, and creating custom alerts on all collected data. Therefore, KQL is the best language for ad-hoc searches against this monitoring data.

Question 4

For incident management, your organization employs ServiceNow.
You're working on an Azure-based application.
When the application fails to authenticate, the company must create a ServiceNow ticket.
Which Azure Log Analytics solution is best for you?

Accepted Answer

IT Service Management Connector (ITSM)

Answer

The IT Service Management Connector (ITSM) in Azure Log Analytics is specifically designed to integrate Azure Monitor alerts with external ITSM solutions like ServiceNow. When an alert is triggered in Azure Monitor (e.g., due to an application authentication failure), the ITSM Connector can automatically create a corresponding incident, event, or work item in ServiceNow, streamlining your incident management process.

Question 5

You're working on a multi-tiered application. The application's front end is hosted in Azure App Service.
The average load times of the application pages must be determined.
What type of material should you use?

Accepted Answer

Azure Application Insights

Answer

Azure Application Insights is the ideal service for determining the average load times of application pages. It is an Application Performance Management (APM) service that automatically collects comprehensive telemetry data from your web application, including request rates, response times, page views, and dependency calls. This data provides detailed insights into the performance and usage patterns of your application, directly showing page load times.
