The lead developer at your company reports that adding new application features takes longer than expected due to a large accumulated technical debt. You need to recommend changes to reduce the accumulated technical debt.
Solution: You recommend reducing the code coupling and the dependency cycles?
Does this meet the goal?

A.    Yes
B.    No

Answer: B
Instead reduce the code complexity. Note: Technical debt is the accumulation of sub-optimal technical decisions made over the lifetime of an application. Eventually, it gets harder and harder to change things: it’s the `sand in the gears’ that sees IT initiatives grind to a halt.

You have an Azure DevOps project. Your build process creates several artifacts. You need to deploy the artifacts to on-premises servers.
Solution: You deploy an Octopus Deploy server. You deploy a polled Tentacle agent to an on-premises server. You add an Octopus task to the deployment pipeline.
Does this meet the goal?

A.    Yes
B.    No

Answer: B
Instead you should deploy an Azure self-hosted agent to an on-premises server. Note: To build your code or deploy your software using Azure Pipelines, you need at least one agent. If your on-premises environments do not have connectivity to a Microsoft-hosted agent pool (which is typically the case due to intermediate firewalls), you’ll need to manually configure a self-hosted agent on on-premises computer(s).

You are building an ASP.NET Core application. You plan to create an application utilization baseline by capturing telemetry data. You need to add code to the application to capture the telemetry data. The solution must minimize the costs of storing the telemetry data. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A.    Add the <InitialSamplingPercentage>99</InitialSamplingPercentage> parameter to the ApplicationInsights.config file.
B.    From the code of the application, enable adaptive sampling.
C.    From the code of the application, add Azure Application Insights telemetry.
D.    Add the <MaxTelemetryItemsPerSecond>5</MaxTelemetryItemsPerSecond> parameter to the ApplicationInsights.config file.
E.    From the code of the application, disable adaptive sampling.

Answer: BD
B: Sampling is a feature in Azure Application Insights. It is the recommended way to reduce telemetry traffic, data costs, and storage costs, while preserving a statistically correct analysis of application data. The Application Insights SDK for ASP.NET Core supports both fixed-rate and adaptive sampling. Adaptive sampling is enabled by default.
D: For adaptive sampling: The volume is adjusted automatically to keep within a specified maximum rate of traffic, and is controlled via the setting MaxTelemetryItemsPerSecond. If the application produces a low amount of telemetry, such as when debugging or due to low usage, items won’t be dropped by the sampling processor as long as volume is below MaxTelemetryItemsPerSecond.

You have an Azure DevOps organization named Contoso and an Azure subscription. The subscription contains an Azure virtual machine scale set named VMSS1 and an Azure Standard Load Balancer named LB1. LB1 distributes incoming requests across VMSS1 instances. You use Azure DevOps to build a web app named App1 and deploy App1 to VMSS1. App1 is accessible via HTTPS only and configured to require mutual authentication by using a client certificate. You need to recommend a solution for implementing a health check of App1. The solution must meet the following requirements:
– Identify whether individual instances of VMSS1 are eligible for an upgrade operation.
– Minimize administrative effort.
What should you include in the recommendation?

A.    an Azure Load Balancer health probe
B.    Azure Monitor autoscale
C.    the Custom Script Extension
D.    the Application Health extension

Answer: D
Monitoring your application health is an important signal for managing and upgrading your deployment. Azure virtual machine scale sets provide support for rolling upgrades including automatic OS-image upgrades, which rely on health monitoring of the individual instances to upgrade your deployment. You can also use health extension to monitor the application health of each instance in your scale set and perform instance repairs using automatic instance repairs.

You have an existing build pipeline in Azure Pipelines. You need to use incremental builds without purging the environment between pipeline executions. What should you use?

A.    a self-hosted agent
B.    Microsoft-hosted parallel jobs
C.    a File Transform task

Answer: A
When you run a pipeline on a self-hosted agent, by default, none of the subdirectories are cleaned in between two consecutive runs. As a result, you can do incremental builds and deployments, provided that tasks are implemented to make use of that. You can override this behavior using the workspace setting on the job.
Not B: The workspace clean options are applicable only for self-hosted agents. When using Microsoft-hosted agents, job are always run on a new agent.

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. Choose two.)

A.    an Azure Automation runbook
B.    an Azure Monitor alert that has a dynamic threshold
C.    an Azure Monitor alert that has a static threshold
D.    the Azure Monitor autoscale settings
E.    an Azure Monitor alert that uses an action group that has an email action

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 build pipeline in Azure Pipelines that occasionally fails. You discover that a test measuring the response time of an API endpoint causes the failures. You need to prevent the build pipeline from failing due to the test. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A.    Set Flaky test detection to Off.
B.    Clear Flaky tests included in test pass percentage.
C.    Enable Test Impact Analysis (TIA).
D.    Manually mark the test as flaky.
E.    Enable test slicing.

Answer: BD

You have an Azure DevOps project named Project1 and an Azure subscription named Sub1. You need to prevent releases from being deployed unless the releases comply with the Azure Policy rules assigned to Sub1. What should you do in the release pipeline of Project1?

A.    Add a deployment gate.
B.    Modify the Deployment queue settings.
C.    Configure a deployment trigger.
D.    Create a pipeline variable.

Answer: A
You can check policy compliance with gates. You can extend the approval process for the release by adding a gate. Gates allow you to configure automated calls to external services, where the results are used to approve or reject a deployment. You can use gates to ensure that the release meets a wide range or criteria, without requiring user intervention.

You have a project in Azure DevOps named Project1. Project1 contains a build pipeline named Pipe1 that builds an application named App1. You have an agent pool named Pool1 that contains a Windows Server 2019-based self-hosted agent. Pipe1 uses Pool1. You plan to implement another project named Project2. Project2 will have a build pipeline named Pipe2 that builds an application named App2. App1 and App2 have conflicting dependencies. You need to minimize the possibility that the two build pipelines will conflict with each ether. The solution must minimize infrastructure costs. What should you do?

A.    Add another self-hosted agent.
B.    Adds Docker Compose task to the build pipelines.
C.    Change the self-hosted agent to use Red Hat Enterprise Linux (RHEL) 8.
D.    Create two container jobs.

Answer: D
To get more control over software dependencies and operating system, you can use Container jobs. Note that the decisions whether to run your pipeline inside a container and whether to use a self-hosted agent are independent. You can directly run your pipeline on a self-hosted agent, or inside a container. You can also execute your pipeline in a container on a Microsoft-hosted agent or on a self-hosted agent.
Not A: For additional control over hardware, you can use a self-hosted build agent.

You have an Azure DevOps project that uses many package feeds. You need to simplify the project by using a single feed that stores packages produced by your company and packages consumed from remote feeds. The solution must support public feeds and authenticated feeds. What should you enable in DevOps?

A.    Universal Packages
B.    upstream sources
C.    views in Azure Artifacts
D.    a symbol server

Answer: B
Upstream sources enable you to use a single feed to store both the packages you produce and the packages you consume from “remote feeds”. This includes both public feeds, such as npmjs.com and nuget.org, and authenticated feeds, such as other Azure DevOps feeds in your organization. Once you’ve enabled an upstream source, any user connected to your feed can install a package from the remote feed, and your feed will save a copy.

You are monitoring the health and performance of an Azure web app by using Azure Application Insights. You need to ensure that an alert is sent when the web app has a sudden rise in performance issues and failures. What should you use?

A.    Custom Events
B.    Application Insights Profiler
C.    Usage Analysis
D.    Smart Detection
E.    Continuous Export

Answer: D
Smart Detection automatically warns you of potential performance problems and failure anomalies in your web application. It performs proactive analysis of the telemetry that your app sends to Application Insights. If there is a sudden rise in failure rates, or abnormal patterns in client or server performance, you get an alert.


You manage the Git repository for a large enterprise application. You need to minimize the data size of the repository. How should you complete the commands? (To answer, select the appropriate options in the answer area.)






You have an Azure web app named Webapp1. You need to use an Azure Monitor query to create a report that details the top 10 pages of Webapp1 that failed. How should you complete the query? (To answer, select the appropriate options in the answer area.)





Drag and Drop

You have a project in Azure DevOps that uses packages from multiple public feeds. Some of the feeds are unreliable. You need to consolidate the packages into a single feed. Which three actions should you perform in sequence? (To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.)





Drag and Drop

You have an Azure DevOps organization named Contoso. You have 10 Azure virtual machines that run Windows Server 2019. The virtual machines host an application that you build and deploy by using Azure Pipelines. Each virtual machine has the Web Server (IIS) role installed and configured. You need to ensure that the web server configurations on the virtual machines is maintained automatically. The solution must provide centralized management of the configuration settings and minimize management overhead. Which four actions should you perform in sequence? (To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.)
