Cisco AppDynamics Associate Performance Analyst 500-420 Prüfungsfragen mit Lösungen (Q65-Q70):

65. Frage
Where would a Performance Analyst view detailed trend graphs representing application performance from the viewpoint of the end user in AppDynamics?

Antwort: C

Begründung:
The Performance Analyst should use Browser Apps. This area contains Browser Real User Monitoring data and presents application performance from the actual end user's perspective. It provides detailed trend graphs for browser pages and AJAX requests, including metrics such as end-user response time, page load time, network time, server time, DOM processing time, resource-loading time, request volume, errors, and geographic or browser-related performance variations.
These measurements enable the analyst to determine whether a performance problem originates in the browser, network, content-delivery path, application server, or a downstream dependency. The graphs can also be filtered by time range, page, browser type, device, operating system, location, and other user-session dimensions.
Transaction Analytics is used for querying and analyzing transaction and business-event data. Remote Services focuses on backend dependencies and external service calls. Applications primarily provides server- side APM visibility into Business Transactions, tiers, nodes, and application flow.
Relevant CAAPA Study Guide topics include Browser Real User Monitoring, Browser Applications, End- User Response Time, Page and AJAX Performance, User Experience Analysis, and Client-Side Performance Trends.


66. Frage
Which option should a Performance Analyst use in an environment where virtual machines are routinely created and destroyed?

Antwort: C

Begründung:
In an elastic environment where virtual machines are frequently provisioned and terminated, the Performance Analyst should enable node-name reuse by using -Dappdynamics.agent.reuse.nodeName together with - Dappdynamics.agent.reuse.nodeName.prefix.
The reuse setting allows an Application Agent to register against an available historical node identity rather than continually creating a new node record each time a replacement virtual machine starts. The prefix groups reusable node names for a particular tier, service, or deployment pool, ensuring that agents select node identities from the correct logical set. This prevents excessive node proliferation in the Controller and preserves cleaner historical monitoring for short-lived infrastructure.
A typical configuration enables reuse and supplies a stable prefix, for example:
-Dappdynamics.agent.reuse.nodeName=true
-Dappdynamics.agent.reuse.nodeName.prefix=checkout-node
Proxy properties only control Controller connectivity through an HTTP proxy. Node metadata and a fixed node name do not provide controlled reuse across an automatically scaling pool.
Relevant CAAPA Study Guide topics include Dynamic and Elastic Environments, Node Name Reuse, Application Agent Registration, Tier and Node Configuration, and Controller Node Management.


67. Frage
Which view allows a Performance Analyst to visualize a single aggregated value representing all of a server's CPU, memory, disk, and network I/O utilization?

Antwort: D

Begründung:
The Tiers and Nodes - Health tab provides a consolidated health representation for the selected server or node. It summarizes underlying infrastructure-resource behavior into a single health-oriented value or status, incorporating indicators associated with processor utilization, memory consumption, disk activity, and network I/O. This enables the Performance Analyst to identify an unhealthy or resource-constrained node quickly without first examining each hardware metric independently.
The Hardware tab is used for deeper analysis of the individual resource categories. It presents separate CPU, memory, disk, and network measurements, allowing the analyst to determine which specific resource is responsible after the Health view indicates degradation.
The Application Dashboard focuses on overall application behavior, Business Transactions, tiers, backends, and application flow rather than providing one aggregated server-resource value. The Metric Browser offers detailed time-series access to individual infrastructure metrics, but it requires manual navigation and comparison rather than presenting the consolidated server-health visualization.
Relevant CAAPA Study Guide topics include Tiers and Nodes Dashboard, Node Health, Server Resource Monitoring, Hardware Metrics, CPU and Memory Utilization, Disk and Network I/O, and Infrastructure-to- Application Correlation.


68. Frage
When should URI Segments be used in Transaction Detection rules?

Antwort: A

Begründung:
URI Segments should be used in Transaction Detection rules when the application is web-oriented. Web- oriented applications often have meaningful information in the URI that can identify different business transactions. URI Segments can help in defining patterns that match specific parts of the URI to distinguish different transactions.

AppDynamics documentation on Transaction Detection: https://docs.appdynamics.com/latest/en/application- monitoring/business-transactions


69. Frage
Which two options are forms of data collectors? (Choose two.)

Antwort: B,E

Begründung:
AppDynamics supports HTTP data collectors and method invocation data collectors for enriching transaction snapshots with contextual diagnostic information.
An HTTP data collector captures selected request details associated with a Business Transaction, including URL or URI information, query or form parameters, HTTP headers, and cookies. These values help analysts distinguish transaction variants, correlate user input with application behavior, and identify request-specific causes of latency or errors. Sensitive values should be filtered or excluded through data-collection configuration.
A method invocation data collector captures information from instrumented application methods. Depending on configuration and agent support, it can collect method arguments, object properties, local or instance data, and return values. This provides code-level context when examining transaction snapshots and call graphs.
URN, URI, and SNMP are not separate AppDynamics transaction data-collector categories in this context.
URI-related values are handled under HTTP request data collection, while SNMP belongs to network- management protocols rather than Application Agent transaction diagnostics.
Relevant CAAPA topics include Transaction Data Collectors, HTTP Request Data Collection, Method Invocation Data Collection, Transaction Snapshots, Sensitive Data Filtering, and Business Transaction Diagnostics.
