You are in the process of building a mobile app aimed at Android and iOS devices. All work items and release cycles are managed via Azure DevOps.
You want to make sure that crash reports for issue analysis is collected, and that beta releases are distributed to your testers. Also, you want to ensure that user feedback on the functionality of new apps is received.
Which of the following must be part of your solution?

  1. The Microsoft Test & Feedback extension.
  2. OWASP ZAP
  3. TFS Integration Platform
  4. Code Style

Answer(s): A

Explanation:

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.

You manage an Azure web app that supports an e-commerce website.

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.

  1. an Azure Automation runbook
  2. an Azure Monitor alert that has a dynamic threshold
  3. an Azure Monitor alert that has a static threshold
  4. the Azure Monitor autoscale settings
  5. an Azure Monitor alert that uses an action group that has an email action

Answer(s): A,B

Explanation:

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.

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.

HOTSPOT (Drag and Drop is not supported)
You have an Azure Kubernetes Service (AKS) pod.
You need to configure a probe to perform the following actions:

Confirm that the pod is responding to service requests. Check the status of the pod four times a minute.
Initiate a shutdown if the pod is unresponsive.

How should you complete the YAML configuration file? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:




Box 1: readinessProbe:
For containerized applications that serve traffic, you might want to verify that your container is ready to handle incoming requests. Azure Container Instances supports readiness probes to include configurations so that your container can't be accessed under certain conditions.

Incorrect Answers:
livenessProbe: Containerized applications may run for extended periods of time, resulting in broken states that may need to be repaired by restarting the container. Azure Container Instances supports liveness probes so that you can configure your containers within your container group to restart if critical functionality is not working.

Box 2: periodSeconds: 15
The periodSeconds property designates the readiness command should execute every 15 seconds.
