Cisco 500-425 Cisco AppDynamics Associate Administrator CAAA Exam Practice Test

Answer : A

The default length of time events can be viewed with full detail before being purged is 7 days, unless archived. Events are records of significant occurrences in the monitored environment, such as errors, exceptions, policy violations, health rule violations, and more. You can view the events in the Controller UI under Events > All Events.You can also archive the events to retain them for longer periods or export them to external systems1Reference:1:Events

Answer : D

According to the Troubleshoot Health Rule Violations document1, one of the ways to troubleshoot health rule violations is to click on the Events tab for the application on the Default Flow Map and then analyze the health rule(s) being violated. This will show you the details of the health rule violation events, such as the affected entity, the severity, the duration, the evaluation time, and the triggered actions. You can also drill down into the health rule violation details to see the health rule configuration, the metric values, and the snapshots. This will help you identify the root cause of the issue and take appropriate remediation actions. Therefore, the correct answer is D. Using the metric browser, disabling the health rule, or rebooting the server may not be the best or the most efficient ways to troubleshoot health rule violations, as they may not reveal the source of the problem, may affect other entities, or may not resolve the issue permanently.Reference:

Two types of information that can be shared without an AppDynamics login are Flow Map and Custom Dashboards. Flow Map is a graphical representation of the application topology, showing the interactions between the tiers, nodes, backends, and remote services. Custom Dashboards are user-defined views of the application performance data, metrics, and events.You can share these types of information by generating a shareable link from the Controller UI, which can be accessed by anyone who has the link, without requiring a login12Reference:1:Share a Flow Map2:Share a Custom Dashboard

Answer : A, C

Snapshots are the detailed records of the execution of a business transaction, including the call stack, the exit points, the errors, and the metrics. To locate snapshots showing slow database response, you can use the following methods:

Go to the list of snapshots and apply a filter based on slow database response: You can access the list of snapshots from the Business Transaction Dashboard or the Tier Dashboard. You can then apply a filter to show only the snapshots that have a slow database response time, which is the time spent by the business transaction in calling the database. You can specify the minimum and maximum values for the slow database response time, or use the predefined options such as slower than 1 second, slower than 5 seconds, etc. You can also combine this filter with other filters, such as time range, business transaction name, tier name, node name, etc.to narrow down the results1.

From the flow map, right-click the database icon and select view snapshots: You can access the flow map from the Application Dashboard, the Business Transaction Dashboard, or the Tier Dashboard. The flow map shows the graphical representation of the flow of the business transactions, including the tiers, the nodes, the backends, and the remote services. You can right-click on any database icon on the flow map and select view snapshots to see the list of snapshots that have called that database.You can then sort or filter the snapshots by the database response time column to find the slowest ones2.

The other options are not valid methods to locate snapshots showing slow database response. Going to the dashboard for the database and selecting slowest database calls will show the metrics and the flow map for the database, but not the snapshots. Going to the list of snapshots and selecting analyze for a group of snapshots will show the summary and the comparison of the selected snapshots, but not the database response time.

Answer : A, B

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 theServer 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) andB(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.Reference:

Answer : A

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 more1You 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 database2Reference:1:Add Database Collectors2: [Link a Database on the Application Flow Map to a Database Instance Monitored by Database Visibility]

Answer : C, D

Health Rules are the rules that define the normal or expected behavior of your application, such as the response time, error rate, or CPU utilization of a business transaction, tier, node, or backend. You can create health rules to monitor the performance and availability of your application and its components. When a health rule is violated, it changes the status of the corresponding key performance indicator (KPI) from normal to warning or critical, depending on the severity of the violation. The status change is also represented as an event in the AppDynamics Controller UI, which can trigger alerts, policies, and actions. You can view the health rule events in the Events tab of the application dashboard, or in the Health tab of the entity dashboard.
