Question 52:
What does the Live Preview option in a Business Transaction Discovery Session allow a user to do?
A. See if new Transaction Discovery Rules work
B. Provide streaming logs from the application agent
C. Search classes and methods currently running on the system
D. Stream entry points in your application
Correct Answer: A
The Live Preview option in a Business Transaction Discovery Session in AppDynamics allows a user to verify the effectiveness of newly configured Transaction Discovery Rules. This feature provides real-time feedback on how these rules
identify and categorize business transactions, enabling users to adjust and fine-tune the rules to ensure accurate and meaningful transaction monitoring.

Question 53:
What is the purpose of a transaction snapshot?
A. To analyze issues with a specific business transaction
B. To analyze issues only with a transaction flagged as stalled
C. To analyze issues with a specific instances of a transaction
D. To analyze issues only with a transaction flagged as slow
Correct Answer: A
A transaction snapshot in AppDynamics is a detailed report of a single execution of a business transaction. Its primary purpose is to analyze issues with a specific business transaction by providing a comprehensive view of the transaction's
execution path, including timing, call graphs, and database queries. This allows performance analystsand developers to drill down into individual transactions to diagnose performance bottlenecks, errors, or anomalies.

Question 54:
A Performance Analyst received an alert that the Average Response Time is increasing after a new marketing offer was released. Which metric would quickly help the Performance Analyst determine that users may not be critically impacted?
A. Errors per Minute increase
B. Calls per Minute decrease
C. Errors per Minute decrease
D. Calls per Minute increase
Correct Answer: D
If the Average Response Time is increasing after the release of a new marketing offer, seeing an increase in Calls per Minute could quickly help the Performance Analyst determine that users may not be critically impacted. This increase may
indicate that despite the higher average response time, more users are engaging with the application, possibly due to interest generated by the marketing offer. It suggests that the system is handling more load, which could be a factor in the
increased response time.
References:
AppDynamics documentation on Performance Metrics: Discusses the implications of various key performance indicators, including how an increase in Calls per Minute can be interpreted in the context of application performance.
Question 55:
Which two functions does the Business Transaction Discovery Feature allow a user to perform? (Choose two.)
A. Identify servers on which to install an AppDynamics application agent
B. Identify new Business transactions in the Business Transaction Dashboard
C. Identify PHP Business Transactions and preview them
D. Identify potential Business Transactions and preview them
E. Identify entry points from uninstrumented code
Correct Answer: BD
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.

Question 56:
What are two examples of backend calls? (Choose two.)
A. a request coming from a browser
B. a tier-to-tier request
C. an asynchronous request
D. a remote services call
Correct Answer: BD
Backend calls in AppDynamics are the interactions that an application component has with external components or services. These can include calls to databases, remote service calls, and interactions between different tiers of an application.
A tier-to-tier request refers to any internal call that happens between different tiers (or nodes) within the same application. For example, a web tier calling an API service tier within the same application ecosystem. A remote services call is an
external call from an application to a service that resides outside of the application's environment, like a call to an external web service, REST API, or a third-party service provider.
Which item supplements business transaction and transaction analytics data with application data?
A. Demarcation collectors
B. Netflow data
C. Data collectors
D. Endpoint sensors
Correct Answer: C
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 58:
A Performance Analyst needs to send a summary report of specific events every two hours. Which feature can enable this automated report summary?
A. Email Templates
B. HTTP Request Templates
C. Email Digests
D. Email / SMS Configuration
Correct Answer: C
To send a summary report of specific events every two hours, a Performance Analyst can use the "Email Digests" feature in AppDynamics. This feature allows for the automated aggregation and delivery of pertinent event information at
predefined intervals, ensuring stakeholders remain informed about the application's performance and significant events without the need for constant manual monitoring.

Question 59:
Which tab within the Application Dashboard displays performance trends for each of Snapshots, Average Response Time, and Events within one central view?
A. Application Flow Map
B. Dashboard
C. Events
D. Transaction Score
E. Network Dashboard
Correct Answer: D
The Transaction Score tab within the Application Dashboard is designed to display performance trends across various metrics including Snapshots, Average Response Time, and Events. It gives a comprehensive view of the transaction
performance, providing a score that reflects the health and reliability of transactions over time.

Question 60:
The performance impact on the_______would lead a Performance Analyst to limit the duration and frequency of automatic diagnostic sessions.
A. Application
B. Controller
C. Network
D. Operating System
Correct Answer: A
The primary concern for a Performance Analyst when considering the impact of automatic diagnostic sessions is the application itself. Intensive diagnostic sessions can be resource-heavy, potentially affecting the application's performance.
Therefore, it is often necessary to limit the duration and frequency of these sessions to ensure they do not negatively impact the application's end-user experience.
