You need to increase the logging level when the web app exceeds normal usage patterns. The solution must minimize administrative overhead.
Which two resources should you include in the solution? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

• an Azure Automation runbook

• an Azure Monitor alert that has a dynamic threshold

• an Azure Monitor alert that has a static threshold

• the Azure Monitor autoscale settings

• an Azure Monitor alert that uses an action group that has an email action

Answer explanation

Correct Answer: AB

A: You can use Azure Monitor to monitor base-level metrics and logs for most services in Azure. You can call Azure Automation runbooks by using action groups or by using classic alerts to automate tasks based on alerts.
B: Metric Alert with Dynamic Thresholds detection leverages advanced machine learning (ML) to learn metrics' historical behavior, identify patterns and anomalies that indicate possible service issues. It provides support of both a simple UI and operations at scale by allowing users to configure alert rules through the Azure
Resource Manager API, in a fully automated manner.

You have a Microsoft ASP.NET Core web app in Azure that is accessed worldwide.
You need to run a URL ping test once every five minutes and create an alert when the web app is unavailable from specific Azure regions. The solution must minimize development time.
What should you do?

• Create an Azure Monitor Availability metric and alert.

• Create an Azure Application Insights availability test and alert.

• Write an Azure function and deploy the function to the specific regions.

• Create an Azure Service Health alert for the specific regions.

Answer explanation

Correct Answer: B
There are three types of Application Insights availability tests:
URL ping test: a simple test that you can create in the Azure portal.

You have a multi-tier application. The front end of the application is hosted in Azure App Service.
You need to identify the average load times of the application pages.
What should you use?

• Azure Application Insights

• the activity log of the App Service

• the diagnostics logs of the App Service

• Azure Advisor

Answer explanation

Correct Answer: A
Application Insights will tell you about any performance issues and exceptions, and help you find and diagnose the root causes.
Application Insights can monitor both Java and ASP.NET web applications and services, WCF services. They can be hosted on-premises, on virtual machines, or as Microsoft Azure websites.

Your company uses ServiceNow for incident management.
You develop an application that runs on Azure.
The company needs to generate a ticket in ServiceNow when the application fails to authenticate.
Which Azure Log Analytics solution should you use?

• Application Insights Connector

• Automation & Control

• IT Service Management Connector (ITSM)

• Insight & Analytics

Answer explanation

Correct Answer: C
The IT Service Management Connector (ITSMC) allows you to connect Azure and a supported IT Service Management (ITSM) product/service.
ITSMC supports connections with the following ITSM tools:
✑ ServiceNow
✑ System Center Service Manager
✑ Provance
✑ Cherwell

HOTSPOT -
Your company is building a new web application.
You plan to collect feedback from pilot users on the features being delivered.
All the pilot users have a corporate computer that has Google Chrome and the Microsoft Test & Feedback extension installed. The pilot users will test the application by using Chrome.
You need to identify which access levels are required to ensure that developers can request and gather feedback from the pilot users. The solution must use the principle of least privilege.
Which access levels in Azure DevOps should you identify? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

• Developers: Stakeholder

  Pilot users: Basic

• Developers: Basic

  Pilot users: Stakeholder

Answer explanation

Box 1: Basic -
Assign Basic to users with a TFS CAL, with a Visual Studio Professional subscription, and to users for whom you are paying for Azure Boards & Repos in an organization.

Box 2: Stakeholder -
Assign Stakeholders to users with no license or subscriptions who need access to a limited set of features.

You use Azure SQL Database Intelligent Insights and Azure Application Insights for monitoring.
You need to write ad-hoc queries against the monitoring data.
Which query language should you use?

• Kusto Query Language (KQL)

• PL/pgSQL

• PL/SQL

• Transact-SQL

Answer explanation

A.Azure Monitor Logs is based on Azure Data Explorer, and log queries are written using the same Kusto query language (KQL). This is a rich language designed to be easy to read and author, and you should be able to start using it with minimal guidance.

Your company creates a web application.
You need to recommend a solution that automatically sends to Microsoft Teams a daily summary of the exceptions that occur in the application.
Which two Azure services should you recommend? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

• Azure Logic Apps

• Azure Pipelines

• Microsoft Visual Studio App Center

• Azure DevOps Project

• Azure Application Insights

Answer explanation

Correct Answer: AE
E: Exceptions in your live web app are reported by Application Insights.
Note: Periodical reports help keep a team informed on how their business critical services are doing. Developers, DevOps/SRE teams, and their managers can be productive with automated reports reliably delivering insights without requiring everyone to sign in the portal. Such reports can also help identify gradual increases in latencies, load or failure rates that may not trigger any alert rules.
A: You can programmatically query Application Insights data to generate custom reports on a schedule. The following options can help you get started quickly:
✑ Automate reports with Microsoft Flow
✑ Automate reports with Logic Apps

Answer explanation

Correct Answer: A
The "Exploratory Testing" extension is now "Test & Feedback" and is now Generally Available.
Anyone can now test web apps and give feedback, all directly from the browser on any platform: Windows, Mac, or Linux. Available for Google Chrome and
Mozilla Firefox (required version 50.0 or above) currently. Support for Microsoft Edge is in the pipeline and will be enabled once Edge moves to a Chromium- compatible web platform.
