  1. Question 1

    Q1

    A manufacturing firm is deploying an on-premises AppDynamics Controller for a high-security environment. The security policy mandates that the Controller's GlassFish application server must not bind to 0.0.0.0 and should only listen on a specific internal IP address. Which configuration file and parameter must be modified to enforce this requirement?

    Show answer & explanation

    Correct answer: B

    The AppDynamics Controller runs on a GlassFish application server. The network listeners for GlassFish are configured in the domain.xml file. To restrict the Controller to a specific IP address, you must modify the address attribute of the relevant element (e.g., for http-listener-1) from the default 0.0.0.0 to the desired IP address. db.cnf is for the MySQL database, controller.sh is for startup scripts, and app-agent-config.xml is for agent configuration.

  2. Question 2

    Q2

    A DevOps team is using the AppDynamics REST API to automate the retrieval of metric data for a custom dashboard. They need to fetch the 'Average Response Time (ms)' for a business transaction named 'Process Payment' within the 'E-Commerce' application. The metric path needs to be constructed correctly for the API call. Which of the following represents the correct metric path format?

    Show answer & explanation

    Correct answer: C

    The AppDynamics REST API for metrics requires a specific, pipe-delimited path. For business transaction metrics, the path starts with 'Business Transaction Performance', followed by 'Business Transactions', the tier name (or application name if it's an overall BT), the BT name, and finally the specific metric name. The other options use incorrect delimiters or path structures.

  3. Question 3

    Q3

    During pre-deployment planning for a global logistics company, the architect must decide on the EUM Server deployment. The company has major user bases in North America, Europe, and Asia, and they want to minimize latency for beacon data transmission. What is the recommended EUM deployment strategy to meet this requirement?

    Show answer & explanation

    Correct answer: B

    For globally distributed users, the SaaS EUM service is the optimal choice. It provides geographically distributed collection points for EUM beacons, ensuring low latency for end-users regardless of their location. This removes the complexity of managing a distributed on-premises EUM infrastructure. A single on-prem server would introduce high latency for distant users. A geo-distributed on-prem deployment is possible but much more complex to manage than using the SaaS offering.

  4. Question 4

    Q4Multiple answers

    An administrator is installing a .NET Agent to monitor a set of critical Windows Services on a server. After running the installer and configuring the Controller details, the services do not appear in the Controller UI. The AppDynamics Agent Coordinator service is running. Which TWO of the following steps are required to complete the instrumentation of Windows Services? (Select TWO).

    Show answer & explanation

    Correct answers: B, C

    By default, the .NET Agent instruments IIS applications. To monitor standalone applications or Windows Services, you must explicitly enable them using the AppDynamics Agent Configuration utility. After specifying the services to instrument, those services must be restarted for the .NET profiler to attach to their processes. The installer typically sets the environment variables, and restarting the Coordinator service alone is insufficient.

  5. Question 5

    Q5

    True or False: When upgrading an on-premises, multi-node Events Service cluster, a rolling upgrade can be performed to maintain availability, but all nodes must be upgraded within the same maintenance window.

    Show answer & explanation

    Correct answer: A

    This statement is true. A rolling upgrade of the Events Service is the recommended procedure to avoid downtime. However, running a mixed-version cluster for an extended period is not supported. The entire upgrade process for all nodes in the cluster should be completed within a single, defined maintenance window to ensure cluster stability and data consistency.

  6. Question 6

    Q6

    A new AppDynamics administrator is tasked with configuring Role-Based Access Control (RBAC) for a team of junior operators. The operators need to view dashboards and metric browser data for the 'Inventory' application but must be prevented from viewing snapshots or changing any configuration. Which built-in role provides the closest match to these requirements?

    Show answer & explanation

    Correct answer: B

    The 'Application Viewer' role is the most appropriate choice. It grants permissions to view most application data, including flow maps, dashboards, and the metric browser, but explicitly denies access to sensitive data like snapshots and prevents any configuration changes. 'Dashboard Viewer' is too restrictive as it only allows viewing dashboards. 'Read-Only User' is a legacy term, and 'Custom Role' would be the next step if 'Application Viewer' wasn't a sufficient match.

  7. Question 7

    Q7

    A consultant is deploying a Standalone Machine Agent on a Linux server that does not have a Java Agent installed. The goal is to monitor basic hardware metrics and run a custom script extension that reports application cache size. After placing the extension script in the correct directory, the custom metrics do not appear in the Metric Browser. What is the most likely reason for this issue?

    Show answer & explanation

    Correct answer: B

    For a Machine Agent to run a custom script extension on a Linux system, the script file itself must have execute permissions. A common oversight is to copy the script to the monitors directory without setting the appropriate permissions (chmod +x script_name.sh). The agent will fail to execute the script, and no metrics will be reported. While ownership and output format are important, the lack of execute permissions is the most frequent and fundamental cause of this specific problem.

  8. Question 8

    Q8

    A financial services company is planning a new AppDynamics on-premises deployment. They have a requirement for end-to-end transaction correlation across two distinct applications that communicate via a proprietary TCP-based messaging queue that is not supported out-of-the-box. The architect needs to determine the best approach to ensure visibility across this boundary. What capability should be central to their pre-deployment plan to address this?

    Show answer & explanation

    Correct answer: C

    When dealing with unsupported protocols or frameworks for transaction correlation, the correct approach is to use custom correlation. This involves defining a custom exit point on the calling application to identify the outbound call and a corresponding custom transaction demarcation (entry point) on the receiving application. The developer must also ensure the AppDynamics correlation header is propagated within the message payload across the proprietary TCP queue. This allows AppDynamics to stitch the two business transactions together.

  9. Question 9

    Q9

    Case Study:

    A regional bank, 'SecureTrust Bank', is modernizing its online banking platform. The current platform is a monolithic Java application running on JBoss, connected to an Oracle database. The bank is moving to a microservices architecture deployed on-premises using Red Hat OpenShift. The new architecture involves approximately 50 microservices communicating via REST APIs and Kafka messaging. The bank has strict security and compliance requirements, including data residency within their own data centers.

    The project team has chosen AppDynamics for performance monitoring. They have a primary data center and a disaster recovery (DR) site. The requirements are to monitor the new OpenShift environment, the legacy JBoss application (during the transition), and the Oracle databases. They need a highly available Controller setup that can fail over to the DR site with minimal data loss. The security team has mandated that all communication between agents and the Controller must be encrypted with their corporate-issued SSL certificates.

    Requirement Summary:

    • Monitor OpenShift (Kubernetes), JBoss, and Oracle.
    • On-premises Controller deployment with High Availability (HA) across two data centers.
    • All agent-to-controller traffic must be encrypted using custom SSL certificates.
    • The deployment must be fully operational before the first set of microservices goes live.

    Which implementation plan best satisfies all of SecureTrust Bank's requirements?

    Show answer & explanation

    Correct answer: B

    This plan correctly addresses all key requirements. It establishes an on-premises HA Controller pair across the two data centers, which is necessary for disaster recovery. It correctly identifies the need to import the custom SSL certificate into the Controller's keystore to secure communications. It also specifies the correct agent types for each part of the environment (Java Agent for JBoss, Cluster Agent for OpenShift, DB Agent for Oracle) and points them to a virtual IP, which is best practice for an HA setup.

  10. Question 10

    Q10

    When instrumenting a mobile application using the Mobile Agent SDK, a developer needs to report a specific business-relevant event, such as 'Item Added to Cart', along with properties like 'Item ID' and 'Price'. Which Mobile SDK method should be used to send this custom data to the AppDynamics platform?

    Show answer & explanation

    Correct answer: D

    The reportEvent method is specifically designed for this purpose. It allows developers to send custom-named events (like 'Item Added to Cart') along with a dictionary or map of key-value properties ('Item ID', 'Price'). This data flows into the Events Service and can be queried using ADQL. reportMetric is for numerical metrics, leaveBreadcrumb is for tracking user flow before a crash, and timers are for measuring custom time intervals.
