Cisco 500-420 Exam is a comprehensive test that covers a wide range of topics related to AppDynamics technology. It tests the candidate's understanding of the AppDynamics architecture, the various components of the AppDynamics platform, and how to configure and manage them. It also tests the candidate's knowledge of AppDynamics best practices, troubleshooting techniques, and performance optimization techniques.
NEW QUESTION # 109
Which view presents a calculated percentage of the slow, very slow, and stalled Business Transactions?
Answer: A
Explanation:
The Transaction Score view presents the calculated percentage of Business Transaction executions classified by performance category, including normal, slow, very slow, stalled, and error transactions. AppDynamics determines these classifications by comparing each transaction's response time with the configured slow and very slow thresholds, which may be based on dynamic baselines or static threshold values.
The resulting Transaction Score provides a concise, application-level indication of user-impacting performance. A rising percentage of slow, very slow, or stalled transactions quickly shows that a greater portion of the workload is experiencing degradation, even when overall average response time appears acceptable.
The Slow Responses troubleshooting view is used to investigate individual slow transaction instances and snapshots rather than calculate the overall percentage distribution. The Business Transactions view lists transaction-level metrics and trends but does not provide the same summarized scoring visualization. The Metric Browser displays raw and aggregated metrics but requires manual selection and interpretation.
Relevant CAAPA Study Guide topics include Transaction Score, Business Transaction Performance Classification, Slow and Very Slow Thresholds, Stalled Transactions, Dynamic Baselines, Transaction Snapshots, and Application Health Analysis.
NEW QUESTION # 110
A Performance Analyst has noticed a significant decrease in an application ' s workload, measured in calls per minute, and is trying to identify the root cause. Which option will give the Performance Analyst insight into the behavior of the affected Business Transactions?
Answer: A
Explanation:
The Performance Analyst should open the Business Transactions view and enable Show Trends. This presents historical behavior for individual Business Transactions, making it possible to identify which transactions experienced a decline in calls per minute and when the change began. The analyst can compare workload patterns across transactions and correlate the decrease with changes in response time, errors, transaction activity, or application usage.
The Top Business Transactions by Load widget emphasizes the highest-volume transactions for the selected period, but it may not clearly expose transactions whose volume has sharply declined. Plotting application- level Calls/min in the Metric Browser confirms that total workload decreased but does not immediately identify the affected Business Transactions. The Application Flow Map focuses on tier and dependency relationships, while Transaction Score summarizes transaction performance classifications rather than workload trends.
The Show Trends capability is therefore the most direct method for examining historical transaction behavior and isolating the Business Transactions responsible for the workload change.
Relevant CAAPA Study Guide topics include Business Transaction Monitoring, Show Trends, Calls per Minute, Workload Analysis, Historical Comparison, and Application Performance Troubleshooting.
NEW QUESTION # 111
Developers and operations personnel complain the Controller tracks many irrelevant Java classes and methods.
How does a Performance Analyst exclude this unhelpful information?
Answer: A
Explanation:
To streamline the monitoring process and enhance the relevance of collected data, AppDynamics allows Performance Analysts to exclude certain Java classes and methods from instrumentation. This is done through the "Configuration > Instrumentation > Call Graph Settings" menu, where irrelevant packages and classes can be specified for exclusion. This approach prevents the AppDynamics agent from tracking unnecessary or irrelevant methods, thus reducing overhead and focusing on the most critical aspects of application performance.
References:
AppDynamics documentation on Call Graph Settings: This section details how to configure call graph settings, including the exclusion of specific classes and methods from instrumentation, to optimize performance monitoring.
NEW QUESTION # 112
Which two roll-up types can be configured for an Information Point? (Choose two.)
Answer: B,D
Explanation:
An Information Point custom metric can be configured with the roll-up types Average and Sum. The selected roll-up determines how values reported by repeated executions of the monitored class and method are aggregated during each metric reporting interval.
Average calculates the mean of all collected values within the interval. This is appropriate for measurements such as average item-processing time, average order value, or another numeric value where typical behavior is the primary concern.
Sum adds all collected values reported during the interval. It is appropriate for cumulative business or operational measurements, such as the total number of items processed, total transaction value, or total quantity handled by the instrumented method.
Max is not one of the configurable Information Point roll-up choices in this context. Although maximum values can appear in other AppDynamics metric-analysis scenarios, they are not selected as an Information Point custom-metric roll-up type. Count is represented separately through invocation-frequency metrics such as Calls per Minute rather than as the configured roll-up method for the collected numeric value.
Relevant CAAPA Study Guide topics include Information Points, Custom Metrics, Metric Aggregation, Average Roll-Up, Sum Roll-Up, Method Invocation Monitoring, and Calls per Minute.
NEW QUESTION # 113
A Performance Analyst is reviewing Business Transactions with an application team. The application team wants to increase the Application Business Transaction limit because it needs visibility into all the different transactions. What should the Performance Analyst do?
Answer: D
Explanation:
The Performance Analyst should first investigate the Business Transactions exceeding the configured limit and determine why so many unique transactions are being registered. Business Transaction limits protect the Controller from excessive metric creation, unnecessary cardinality, and degraded monitoring performance.
A high transaction count is often caused by overly granular transaction naming, dynamic URL segments, request parameters, identifiers, or automatic discovery rules that create a separate Business Transaction for each variation. The analyst should review All Other Traffic, transaction detection rules, naming rules, and the entry points generating excessive registrations. Low-value traffic such as health checks, static resources, or framework-generated requests can be excluded, while related requests can be grouped or split more deliberately through Custom Match Rules.
Increasing the limit without correcting the underlying detection behavior may only postpone the problem and increase Controller resource consumption. The limit should be raised only after the transaction model has been validated and a genuine business requirement remains.
Relevant CAAPA Study Guide topics include Business Transaction Limits, All Other Traffic, Transaction Detection Rules, Custom Match Rules, Exclude Rules, Transaction Naming, and Metric Cardinality Management.
