List of questions
Question 41

What AppDynamics Alert Action does a Performance Analyst need to select to post an AppDynamics event to a third-party collaboration tool?
Make an HTTP Request
Take a thread dump
Create or Update a JIRA Ticket
Run a script or executable on problematic nodes
Explanation:
To post an AppDynamics event to a third-party collaboration tool, the Performance Analyst needs to select the 'Make an HTTP Request' alert action. This action allows AppDynamics to send an HTTP request to a specified URL, which can be the endpoint provided by the third-party tool's API. This integration capability enables the automatic posting of events, alerts, and notifications from AppDynamics to collaboration tools, enhancing communication and response times to performance issues.
AppDynamics documentation on Alert and Respond: Details the various alert actions available within AppDynamics, including the ability to make HTTP requests to integrate with external systems.
Question 42

Which item supplements business transaction and transaction analytics data with application data?
Demarcation collectors
Netflow data
Data collectors
Endpoint sensors
Explanation:
Data collectors in AppDynamics supplement business transaction and transaction analytics data with application data by capturing additional information during transaction execution. This can include method arguments, return values, and invocation context, which enriches the transaction data with more detailed application-level insights. This capability is crucial for in-depth performance analysis and troubleshooting, providing a more comprehensive view of application behavior.
AppDynamics documentation on Data Collectors: Explains how to configure data collectors to capture and display detailed application data within business transactions.
Question 43

A Business Transaction was registered and displayed on the Business Transaction Dashboard. It has continuous load on it. After an hour the Business Transaction stopped being displayed in the Business Transaction Dashboard. Which action stopped the display of the Business Transaction?
The Business Transaction Lock Down was enabled an hour ago.
The Business Transaction had been deleted an hour ago from the Business Transaction Dashboard.
The Business Transaction Custom Match Rule was deleted an hour ago.
The Business Transaction had been excluded an hour ago from the Business Transaction Dashboard.
Explanation:
If a Business Transaction stops being displayed on the Business Transaction Dashboard after continuous load, it could be due to the deletion of the Business Transaction Custom Match Rule. Custom Match Rules in AppDynamics are used to define custom business transactions based on specific criteria. If such a rule is deleted, transactions that were previously identified and displayed based on that rule may no longer be recognized as distinct business transactions, leading to their disappearance from the dashboard.
AppDynamics documentation on Business Transactions: Provides insights on configuring and managing business transactions, including the use of custom match rules.
Question 44

Which two methods are used to plot Host CPU and GC Time Spent in a single view? (Choose two.)
Server tab under 'Tiers and Nodes'
JMX tab under 'Tiers and Nodes'
Memory tab under Tier and Nodes'
Metrics Browser
Explanation:
To plot Host CPU and GC (Garbage Collection) Time Spent in a single view, the 'JMX tab under 'Tiers and Nodes'' and the 'Metrics Browser' are the appropriate methods. The JMX tab provides access to Java Management Extensions (JMX) metrics, including those related to GC time. The Metrics Browser allows for the customization and aggregation of various metrics, including Host CPU usage and GC metrics, enabling a combined view of these critical performance indicators.
AppDynamics documentation on Monitoring Tiers and Nodes: Discusses the JMX metrics available for Java applications, including garbage collection details.
AppDynamics documentation on the Metrics Browser: Describes how to use the Metrics Browser to view and analyze a wide range of performance metrics.
Question 45

Which type of Data Collector will capture code data such as method arguments, variables, and return values?
Method Invocation Data Collector
Servlet Container Collector
Transaction Data Collector
URI Data Collector
Explanation:
The 'Method Invocation Data Collector' is specifically designed to capture code-level data such as method arguments, variables, and return values. This type of data collector enables deep visibility into the execution of methods within transactions, providing valuable insights into the application's behavior and performance. This detailed level of monitoring is essential for diagnosing complex issues and understanding the inner workings of business transactions.
AppDynamics documentation on Data Collectors: Details the types of data collectors available, including Method Invocation Data Collectors, and how they can be used to capture detailed code-level data.
Question 46

When using the REST interlace where would a Performance Analyst go to see all of the captured endpoints by service?
Navigate to the Metric Browser then to the specific metric. Copy the REST URL from the Metric Browser and then use a wildcard query to get the metrics for other SEPs.
Navigate to the Applications browser then drill down the requested endpoint with the available Dashboard & Metrics indicators then selected the desired metric.
Navigate to the Metric Browser then to the Consumed Endpoints location. Drill down in the metric browser on the specific endpoint to call out its services.
Access the MySQL database and find all the endpoints in an app. where can drill down to the tier and transactions using the endpoints. Select the appropriate REST feature enabled by the service endpoint.
Explanation:
To view all captured endpoints by service using the REST interface in AppDynamics, a Performance Analyst would navigate to the Metric Browser and proceed to the 'Consumed Endpoints' section. From there, drilling down on specific endpoints within the Metric Browser allows the analyst to explore the services associated with each endpoint. This method enables detailed analysis of endpoint metrics, facilitating the monitoring and optimization of service performance.
AppDynamics documentation on Metric Browser: Guides on navigating the Metric Browser to access and analyze various application metrics, including those related to endpoints and services.
AppDynamics documentation on REST API: Provides information on how to utilize the REST API for retrieving metrics, including endpoint data.
Question 47

Which two functions does the Business Transaction Discovery Feature allow a user to perform? (Choose two.)
Identify servers on which to install an AppDynamics application agent
Identify new Business transactions in the Business Transaction Dashboard
Identify PHP Business Transactions and preview them
Identify potential Business Transactions and preview them
Identify entry points from uninstrumented code
Explanation:
The Business Transaction Discovery feature in AppDynamics allows users to identify new and potential business transactions directly within the Business Transaction Dashboard. This feature aids in the continuous monitoring and adaptation of the application's transaction tracking to changing business needs, ensuring comprehensive visibility. Users can also preview these identified transactions, assessing their relevance and impact on the application's performance before deciding to monitor them as official business transactions.
AppDynamics documentation on Business Transaction Monitoring: Discusses how to manage and monitor business transactions, including the discovery and preview of new or potential transactions.
AppDynamics documentation on Business Transaction Dashboard: Explains the functionalities and features of the Business Transaction Dashboard, including transaction discovery.
Question 48

A Performance Analyst needs to send a summary report of specific events every two hours. Which feature can enable this automated report summary?
Question 49

Which option should a Performance Analyst use in an environment where virtual machines are routinely created and destroyed?
Question 50
