Requirements traceability is the ability to relate and document two or more phases of a development process, which can then be traced both forward or backward from its origin. Requirements traceability help teams to get insights into indicators such as quality of requirements or readiness to ship the requirement. A fundamental aspect of requirements traceability is association of the requirements to test cases, bugs and code changes.

NEW QUESTION 255
You have a containerized solution that runs in Azure Container Instances. The solution contains a frontend container named App1 and a backend container named DB1. DB1 loads a large amount of data during startup. You need to verify that DB1 can handle incoming requests before users can submit requests to App1. What should you configure?

A.    a liveness probe
B.    a performance log
C.    a readiness probe
D.    an Azure Load Balancer health probe

Answer: C
Explanation:
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:
Not A: 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.

NEW QUESTION 256
You have an Azure DevOps organization named Contoso. You need to receive Microsoft Teams notifications when work items are updated. What should you do?

A.    From Azure DevOps, configure a service hook subscription.
B.    From Microsoft Teams, configure a connector.
C.    From Microsoft Teams admin center, configure external access.
D.    From Microsoft Teams, add a channel.
E.    From Azure DevOps, install an extension.

Answer: A
Explanation:
Service hooks let you run tasks on other services when events happen in your Azure DevOps projects. For example, create a card in Trello when a work item is created or send a push notification to your team’s mobile devices when a build fails. You can also use service hooks in custom apps and services as a more efficient way to drive activities when events happen in your projects. Note: Service hook publishers define a set of events. Subscriptions listen for the events and define actions to take based on the event. Subscriptions also target consumers, which are external services that can run their own actions, when an event occurs.
https://docs.microsoft.com/en-us/azure/devops/service-hooks/overview

NEW QUESTION 257
You have an Azure DevOps organization named Contoso and an Azure subscription. The subscription contains an Azure virtual machine scale set named VMSS1 that is configured for autoscaling. You use Azure DevOps to build a web app named App1 and deploy App1 to VMSS1. App1 is used heavily and has usage patterns that vary on a weekly basis. You need to recommend a solution to detect an abnormal rise in the rate of failed requests to App1. The solution must minimize administrative effort. What should you include in the recommendation?

A.    the Smart Detection feature in Azure Application Insights
B.    the Failures feature in Azure Application Insights
C.    an Azure Service Health alert
D.    an Azure Monitor alert that uses an Azure Log Analytics query

Answer: A
Explanation:
After setting up Application Insights for your project, and if your app generates a certain minimum amount of data, Smart Detection of failure anomalies takes 24 hours to learn the normal behavior of your app, before it is switched on and can send alerts.
https://docs.microsoft.com/en-us/azure/azure-monitor/app/proactive-failure-diagnostics

NEW QUESTION 258
You have a web app hosted on Azure App Service. The web app stores data in an Azure SQL database. You need to generate an alert when there are 10,000 simultaneous connections to the database. The solution must minimize development effort. Which option should you select in the Diagnostics settings of the database?

A.    Send to Log Analytics.
B.    Stream to an event hub.
C.    Archive to a storage account.

Answer: A
