Correct answers: A Critical condition where the value of `Business Transaction Performance > 95th Percentile Response Time (ms)` is `> (Baseline + 40%)` of the `Daily Trend`.; A Warning condition where the value of `Business Transaction Performance > 95th Percentile Response Time (ms)` is `> (Baseline * 1.2)` of the `Daily Trend`.

Correct answer: An Information Point configured on the `cart.addItem(Item item)` method.

Information Points are specifically designed to monitor business metrics from code that is not part of a Business Transaction entry point. By creating an Information Point on the `addItem` method, AppDynamics will automatically create metrics for Calls per Minute, which directly corresponds to the number of items added to carts, and this metric can then be used in custom dashboards.

Correct answer: Define a POJO-based Service Endpoint on the class containing the `calculateShippingRoute()` method.

A Service Endpoint is the ideal feature for this scenario. It allows you to monitor the performance of a specific class/method (a POJO in this case) as a distinct entity, complete with its own metrics like average response time and calls per minute. This isolates its performance from the calling Business Transactions and allows for independent trending, dashboarding, and health rule configuration, directly addressing all of the company's requirements.

Correct answer: True

This is true. The primary purpose of marking a transaction as a background task is to exclude its performance metrics (like slow or error transactions) from contributing to the application's overall health score and key performance indicators, as they are often long-running and not user-facing.

Correct answer: Thread contention for a shared resource.

'Time Waiting for Lock' explicitly indicates that the transaction's thread was blocked, waiting to acquire a lock (such as a synchronized block in Java) that was held by another thread. This is a classic sign of thread contention, where multiple threads are competing for exclusive access to the same resource.

Correct answer: An HTTP Request Data Collector.

The HTTP Request Data Collector is specifically designed to extract data from incoming HTTP requests, including headers, cookies, and parameters. To capture the `X-Customer-ID` header, the analyst would configure an HTTP Request Data Collector and specify the header name.

Correct answer: In the Dashboard's 'Settings' or 'Edit' mode.

The auto-refresh interval is a property of the individual dashboard. It can be configured by entering the dashboard's 'Edit' mode and accessing its settings, where the refresh interval can be enabled and set to the desired value, such as 1 minute (60 seconds).

Correct answers: Windows Performance Counters for .NET CLR Memory.; Windows Performance Counters for .NET CLR Exceptions.

Correct answer: Create a custom transaction threshold configuration for '/api/v1/healthcheck' and disable the 'Slow' threshold.

Transaction thresholds can be configured on a per-transaction basis. By creating a custom configuration for the specific health check transaction, the analyst can disable the 'Slow' threshold. This stops the creation of 'Slow Transaction' events for this BT only, while still collecting all other performance metrics like response time and error rate.

Correct answer: In the 'Memory' tab of the Node Dashboard for the affected node.

Data from memory diagnostic sessions, including Automatic Leak Detection and Object Instance Tracking, is displayed in the 'Memory' tab of the specific Node Dashboard. This tab provides views for memory usage, garbage collection, and a dedicated section for analyzing memory leak data collected during diagnostic sessions.
