To capture business data for Transaction Analytics what must be configured first?
- A. an Information Point
- B. a Custom Metric
- C. a Data Collector
- D. a Health Rule
正解：C
解説：
Explanation
To capture business data for Transaction Analytics, you must first configure a data collector. A data collector is a configuration that specifies what data to capture from a business transaction and how to store it in the analytics platform. You can capture data from HTTP requests, method invocations, custom fields, or information points. You can also apply filters and transformations to the captured data. Once you have configured a data collector, you can use it to enrich the transaction analytics data with business context and enable advanced queries and visualizations

To alert the operations team that a cloud-based application has provisioned a new instance of a JVM, which standard action should an administrator take?
- A. Create a Policy trigger for Application Change > New Tier
- B. Set up a simple extension that checks the number of nodes in a Tier and insert an event
- C. Create a Policy trigger for Discovery > New Node Discovered
- D. Create a Policy trigger for Server Restart > New Node Discovered.
正解：C
解説：
Explanation
To alert the operations team that a cloud-based application has provisioned a new instance of a JVM, an administrator should create a policy trigger for Discovery > New Node Discovered. This policy trigger will fire an event when a new node is discovered by the AppDynamics Controller, either by auto-discovery or manual registration. The event will contain information such as the node name, tier name, application name, and agent type. The administrator can then configure an action to send an email, SMS, or custom notification to the operations team with the event details. Alternatively, the administrator can also use the built-in alerting feature of the cloud provider to notify the operations team of the new instance creation.

質問 # 30
When creating a Health Rule condition, which two metrics could baselines be used instead of defining a specific threshold? (Choose two.)
- A. an expression containing multiple metrics
- B. overall average response time
- C. calls per millisecond
- D. Business Transaction errors per minute
- E. a metric with an average baseline of zero
正解：A、B
解説：
Explanation
When creating a Health Rule condition, you can use baselines instead of defining a specific threshold for some metrics. Baselines are the dynamic values that represent the normal or expected behavior of a metric, based on the historical data collected by the AppDynamics Cognition Engine. Using baselines can help you account for the variations and seasonality of your application performance, and avoid false positives or negatives. You can use baselines for metrics that have a non-zero average value and a meaningful deviation, such as the overall average response time of a business transaction or an expression containing multiple metrics. You cannot use baselines for metrics that have a zero average value or a negligible deviation, such as the Business Transaction errors per minute or the calls per millisecond.https://www.appdynamics.com/product/how-it-works/application-performance-baseline

質問 # 31
A customer wants to monitor 50th and 99th percentile response time in the Metric Browser for a particular Business Transaction Where do you configure and enable percentile metrics?
- A. Configuration > Instrumentation > Configure Percentile Metrics
- B. Configuration > Instrumentation > Transaction Detection > Configure Percentile Metrics
- C. Configuration > Baselines > Configure Percentile Metrics
- D. Configuration > Slow Transaction Thresholds > Configure Percentile Metrics
正解：D
解説：
Explanation
Percentile metrics are a way to measure the distribution of response times for a Business Transaction. They show the value below which a certain percentage of measurements fall. For example, the 50th percentile metric shows the median response time, and the 99th percentile metric shows the worst-case response time for
99% of the transactions. To enable percentile metrics, you need to go to Configuration > Slow Transaction Thresholds and indicate 5 whole numbers between 1 and 99 as Percentiles to Collect. You can then view the percentile metrics in the Metric Browser under Business Transaction Performance > Business Transactions >
<Application Name> > <Business Transaction Name> > Percentiles.

- B. Top 10 Connections by Application
- C. Average Number of Slow Connections
- D. Top 10 Query Wait States
- E. Top Leaked Connections
正解：C、E
解説：
Explanation
Database Visibility provides metrics on the performance of your database and helps troubleshoot performance-related issues. Database Visibility consists of four main components: Database Agent, Collector, Controller, and Events Service (on-premises only). The Database Agent is a standalone Java program that collects performance metrics about your database instances and database servers. The Collector is the process that runs within the Database Agent to collect performance metrics about your database instances and database servers. The Controller is the central interface where you can see all your database instances and database server performance metrics. The Events Service stores high volumes of metric data.
According to the Overview of Database Visibility, the following types of information are sent to the Controller:
Database-level metrics, such as the number of queries processed and other database statistics Names and attributes of all sessions, clients, queries, and other objects on the monitored system The following types of information are sent to the Events Service:
Time that each query spends at each wait state
Individual query statistics for databases that support it
Information about individual execution plans in databases that support it Therefore, B (Average Number of Slow Connections) and C (Top Leaked Connections) are two stats that are available in Database Visibility. References:

While troubleshooting a performance issue on a Java application the engineer determines there is a possible memory leak in the JVM Using AppDynamics, how would the engineer determine rf there is a memory leak?
- A. Examine the values on the Server tab on one of the affected Nodes.
- B. Configure Object Instance Tracking on the Tier in question.
- C. Analyze the information on the Memory tab on one of the affected Nodes
- D. Verify and adjust the Memory Monitoring configuration for the Tier in question
正解：C
解説：
Explanation
According to the Java Memory Leaks document1, one of the ways to detect and troubleshoot Java memory leaks is to use the Automatic Leak Detection feature on the Memory tab of the Node Dashboard. This feature captures and analyzes the collections that are actively used and growing in size over time, indicating a potential memory leak. You can also drill down into the leaking collections to see the content summary and the access traces that show the code path and the business transactions that access the collection. Therefore, the correct answer is D. Examining the values on the Server tab, configuring Object Instance Tracking, or verifying and adjusting the Memory Monitoring configuration may not directly reveal the source of the memory leak, but they may provide some useful information or metrics to support the diagnosis.

Node-name: This property defines the name of the node that appears in the Controller UI. You can use the GUI to change the node name or use auto-naming rules based on environment variables or system properties1 Max-business-transactions per node: This property sets the maximum number of business transactions that can be registered on a node. If the number of business transactions exceeds this limit, the agent stops registering new business transactions and reports them as "All Other Traffic". You can use the GUI to increase or decrease this limit2 References: 1: Node Naming 2: Configure Business Transaction Limits
質問 # 40
Which two would be marked as an exception in AppDynamics? (Choose two)
- A. HTTP errors that do not occur in the context of a Business Transaction
- B. a handled exception after the business transaction terminates
- C. a custom-configured error method and error message
- D. any message that is logged with a severity of Error or Fatal
正解：C、D
解説：
Explanation
An exception in AppDynamics is a code-level event that indicates a problem or abnormality in the execution of a business transaction. AppDynamics captures and presents information on exceptions in the monitored environment, and allows you to configure the rules and criteria for detecting and reporting exceptions.
According to the Errors and Exceptions - AppDynamics, the following two types of events would be marked as an exception in AppDynamics:
A custom-configured error method and error message: This is a type of event that you can define as an exception based on a specific method and message that indicate an error condition in your application code. You can configure the error detection rules to mark a business transaction as an error and capture the exception information when such a method and message are encountered. For example, you can configure a rule to mark a business transaction as an error and capture the exception when the method com.example.MyClass.myMethod returns the message Invalid input.
Any message that is logged with a severity of Error or Fatal: This is a type of event that AppDynamics automatically detects as an exception based on the log messages that are generated by your application code. AppDynamics scans the log messages for the keywords Error or Fatal, and marks the business transaction as an error and captures the exception information when such a message is found. For example, AppDynamics will mark a business transaction as an error and capture the exception when the log message contains Error: Null pointer exception.
Therefore, B (a custom-configured error method and error message) and C (any message that is logged with a severity of Error or Fatal) are two types of events that would be marked as an exception in AppDynamics.

質問 # 41
The applications and servers are running normally What are two important reasons for the engineer to view and analyze server performancedata at this time? (Choose two.)
- A. Collecting Server metric performance during normal operations helps determine code problems
- B. Visualizing application performance during normal operations helps identify when the application performance is abnormal.
- C. Graphs and charts collected at this time are useful for showing application owners the stability of their application
- D. Collecting the errors during this period will identify memory problems in the application.
正解：B、C
解説：
Explanation
Server performance data is the information that AppDynamics collects and reports about the health and availability of the servers that host your applications and their components. Server performance data includes metrics such as CPU utilization, memory usage, disk I/O, network traffic, and so on. You can use server performance data to monitor and troubleshoot the performance issues of your servers and applications.
According to the Server Visibility - AppDynamics, the following two reasons are important for the engineer to view and analyze server performance data at this time:
Visualizing application performance during normal operations helps identify when the application performance is abnormal: This means that by comparing the current server performance data with the historical or baseline data, you can detect any anomalies or deviations that may indicate a potential problem or degradation of your application performance. For example, you can use the Server Dashboard to see the current and historical trends of the server metrics, and use the Anomaly Detection feature to identify any outliers or unusual patterns.
Graphs and charts collected at this time are useful for showing application owners the stability of their application: This means that by using the graphical and visual representations of the server performance data, you can communicate and demonstrate the reliability and efficiency of your application to the stakeholders and customers. For example, you can use the Server Health Report to generate a summary of the server health status, availability, and performance over a specified time period, and share it with the application owners.
Therefore, A (Visualizing application performance during normal operations helps identify when the application performance is abnormal) and B (Graphs and charts collected at this time are useful for showing application owners the stability of their application) are two important reasons for the engineer to view and analyze server performance data at this time.

Your organization has defined a set of health rules that accurately represent the business functions of its applications. Which two ways should you help the organization see the current status of health rules and events of the business process? (Choose two.)
- A. Create a report that runs every night and sends out the status.
- B. Set up a policy to send an email or text when a health rule status changes.
- C. Leave the mam applications page open for all to see
- D. Create a dashboard with health and events widgets displayed.
正解：B、D
解説：
Explanation
Health rules are the criteria that AppDynamics uses to evaluate the performance and availability of your applications and their components. Health rules can trigger alerts and actions when the conditions are violated or cleared. Events are the occurrences that AppDynamics records when something significant happens in your monitored environment, such as a health rule violation, a policy execution, a deployment, or a custom event.
According to the Health Rules - AppDynamics, the following two ways can help you see the current status of health rules and events of the business process:
Set up a policy to send an email or text when a health rule status changes: This way, you can get notified in real time when a health rule condition is met or cleared, and take appropriate actions to resolve or prevent issues. You can configure policies to send emails, texts, or other notifications to specific recipients or groups, and include relevant information such as the health rule name, the affected entity, the severity level, and the time range.
Create a dashboard with health and events widgets displayed: This way, you can visualize the health and performance of your applications and their components in a single view, and drill down to the details of each health rule or event. You can create custom dashboards with various widgets that show the health status, the event list, the event summary, the event correlation, and the event timeline of your applications and their components.
Therefore, A (Set up a policy to send an email or text when a health rule status changes) and D (Create a dashboard with health and events widgets displayed) are two ways that can help you see the current status of health rules and events of the business process. References:

- D. You can clean up stale database connections
正解：A
解説：
Explanation
The main benefit of defining Database Collectors is that you can see which applications are calling a database and how they impact the database performance. Database Collectors enable the Database Agent to collect data from your database instances and database servers, such as metrics, queries, sessions, wait states, and more1 You can also link a database on the application flow maps to a database instance monitored by Database Visibility, which allows you to see the correlation between the application and the database2 References: 1: Add Database Collectors 2: [Link a Database on the Application Flow Map to a Database Instance Monitored by Database Visibility]
質問 # 45
After agents are installed, and application data is flowing through a Java application, a user sees that a remote database has not been discoveredin a known Business Transaction.To determine and configure the exit call to the database where would you go?
- A. Database Calls > Options > Backend Detection > JDBC
- B. Configuration > Java > Backend Detection > JDBC
- C. Databases > Configuration > Collectors
- D. Configuration > Instrumentation > Backend Detection > Java
正解：D
解説：
Explanation
To determine and configure the exit call to the database, you need to go to Configuration > Instrumentation > Backend Detection > Java. An exit call is a call from an application component to an external service or system, such as a database, a web service, a message queue, or a cache. A backend is a logical representation of an external service or system that receives exit calls from an application component. AppDynamics automatically detects and identifies common types of backends, such as JDBC, HTTP, JMS, and so on.
According to the Exit Point Detection Rules - AppDynamics, the following steps are required to determine and configure the exit call to the database:
Go to Configuration > Instrumentation > Backend Detection > Java.
Select the application and the tier that contains the exit call to the database.
Click the Add button to create a new exit point detection rule.
Enter a name and description for the rule.
Select the type of exit call from the drop-down list, such as JDBC, HTTP, JMS, and so on.
Specify the class and method that make the exit call to the database.
Specify the match criteria for the exit call, such as the URL, the query, the host, the port, and so on.
Click Save.
Therefore, C (Configuration > Instrumentation > Backend Detection > Java) is the correct answer.

An HTTP Data Collector can capture which three kinds of data? (Choose three.)
- A. Headers
- B. Method Invocation
- C. Cookies
- D. Parameter Values
- E. Variables
正解：A、C、D
解説：
Explanation
An HTTP Data Collector is a type of data collector that captures data from HTTP requests and responses. It can capture three kinds of data: parameter values, headers, and cookies. Parameter values are the values of the query string or form parameters in the HTTP request. Headers are the key-value pairs that are sent or received as part of the HTTP request or response. Cookies are the small pieces of data that are stored by the browser and sent to the server with each request. An HTTP Data Collector can be configured to capture any of these data types by specifying the name of the parameter, header, or cookie in the data collector settings. The captured data can be used for various purposes, such as adding context to business transactions, creating custom metrics, or triggering health rules.

質問 # 47
By default, which two Sensitive Data Filters substring does the Java Agent enable? (Choose two.)
- A. substring "ssn"
- B. substring "credit card"
- C. substring "key"
- D. substring "password"
- E. substring "account"
正解：C、D
解説：
Explanation
By default, the Java Agent enables two Sensitive Data Filters substring: substring "key" and substring
"password". These filters prevent the agent from capturing and sending any data that contains these substrings to the Controller, such as query parameters, HTTP headers, cookies, environment variables, or system properties. This helps to protect sensitive information from being exposed in the Controller UI or reports. You can also add more filters or modify the existing ones by editing the agent configuration file1 References: 1: Filter Sensitive Data
質問 # 48
Which two conditions would be a reason to update an existing Data Collector? (Choose two.)
- A. A new method parameter has been added to an instrumented class
- B. A new HTTP parameter has been added to an existing Business Transaction
- C. The Business Transaction has been deprecated.
- D. A new class and method have been deployed to the application.
正解：A、D
解説：
Explanation
According to the Data Collectors document1, a data collector is a configuration that captures application data from a method invocation or an HTTP request. A data collector is associated with a specific method signature or an HTTP parameter name. Therefore, if a new class and method have been deployed to the application, or a new method parameter has been added to an instrumented class, the existing data collector may not match the new code and may need to be updated. However, if the business transaction has been deprecated, or a new HTTP parameter has been added to an existing business transaction, the existing data collector may still work as expected, unless the data collector is specifically configured to filter by the business transaction name or the HTTP parameter value. References:
Data Collectors
