500-430 Cisco AppDynamics Professional Implementer(CAPI) Free Practice Exam Questions (2025 Updated)

According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the REST API for health rule violations allows you to retrieve information about the health rule violations that occurred in a specified time range for a given application1. You can use the REST API for health rule violations for the following valid reasons:

For determining which actions have been executed (B): The REST API response includes the details of the actions that were triggered by the health rule violation, such as email, SMS, HTTP request, or custom action1. You can use this information to verify if the actions were executed successfully, or to troubleshoot any issues with the action execution.

When searching for historical events ©: The REST API allows you to specify a custom time range for retrieving the health rule violations, such as BEFORE_TIME, AFTER_TIME, BETWEEN_TIMES, or BEFORE_NOW1. You can use this feature to search for historical events that occurred in the past, or to analyze the trends and patterns of the health rule violations over time.

The incorrect options are:

For updating an AppDynamics dashboard (A): This is not a valid reason for using the REST API for health rule violations, because the AppDynamics dashboards already display the health rule violations that occurred in the selected time frame, along with the severity, status, affected entities, and actions2. You do not need to use the REST API to update the dashboard, as the dashboard is automatically refreshed with the latest data from the Controller.

For sending emails (D): This is not a valid reason for using the REST API for health rule violations, because the REST API does not send emails directly. The REST API only returns the information about the health rule violations, and the actions that were triggered by them. If you want to send emails based on the health rule violations, you need to configure an email action in the health rule configuration, or use a custom action that invokes an external email service3.

When pushing events to the Event Management System is NOT possible (E): This is not a valid reason for using the REST API for health rule violations, because the REST API does not push events to the Event Management System. The REST API only returns the information about the health rule violations, and the actions that were triggered by them. If you want to push events to the Event Management System, you need to configure an HTTP request action in the health rule configuration, or use a custom action that invokes an external API3.

A custom action is a type of Alert and Respond action that allows you to integrate AppDynamics notifications with your own alerting or ticketing system. You can create a custom action by writing an executable script and an XML file that describe how to pass information from AppDynamics to your system. A custom action can be triggered by a policy based on a health rule violation or an event. A custom action is available only on an on-premises Controller, because it requires access to the Controller file system and the ability to execute scripts on the Controller host machine. For a SaaS Controller, you can use HTTP request templates instead of custom actions to integrate with external systems. References: Build a Custom Action, Alert and Respond, Actions, Custom Actions

The AppDynamics Controller Admin Console lets you configure certain global settings for the Controller, such as metric retention periods, UI notification triggers, tenancy mode, and accounts in multi-tenancy mode1. Two of the settings that an administrator can configure from the AppDynamics Controller Admin Console are:

License allocation: This setting allows you to view and manage the license usage and availability for your Controller. You can see the total number of licenses, the number of licenses in use, the number of licenses available, and the license expiration date for each agent type. You can also allocate licenses to specific applications or accounts, and set license limits and alerts2.

Retention periods: This setting allows you to specify how long the Controller retains the metric data and the event data for your monitored applications. You can configure the retention periods for different types of data, such as minute-level metrics, hour-level metrics, day-level metrics, transaction snapshots, and events. You can also configure the data purge schedule and the data backup schedule3.

To set up AppDynamics Controllers as a high availability pair, you need to meet the following requirements1:

Passwordless SSH must be configured between the two Controller servers. This allows the Enterprise Console to automate the configuration and administration tasks associated with a highly available deployment on Linux systems.

Both servers must have the Controller software installed prior to setting up high availability. The Controllers in an HA pair must be equivalent versions, and be in the same data center.

Both servers must have identical directory structures for the Controller installation. The individual machines in the Controller HA pair need to have an equivalent amount of disk space. References: Prerequisites for High Availability

To install a .NET Agent patch, which is a minor update to the existing .NET Agent version, you do not need to uninstall the old agent or restart the machine. You only need to follow these steps:

Download the .NET Agent patch from the AppDynamics Download Center.

Launch an elevated command prompt with full administrator privileges.

Execute the Installer.bat file from the patch archive. The batch file installs the patch and starts the AppDynamics Agent Coordinator service.

Restart the instrumented applications, such as IIS, Windows services, or standalone applications.

 According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the method to import an existing keypair to manage the Controller SSL certificate without using the Enterprise Console UI is to add the keypair to the keystore.jks using a third-party tool (A). The keystore.jks file is the default keystore for the Controller that contains the private keys and certificates for the secure communication on port 8181. If the administrator already has a custom keypair that is signed by a third-party Certificate Authority (CA) or an internal CA, they can use a third-party tool, such as KeyStore Explorer or OpenSSL, to import the keypair into the keystore.jks file. The administrator should also import the root or intermediate certificates of the CA into the cacerts.jks file, which is the default truststore for the Controller. The administrator should use the keytool utility, which is bundled with the Controller installation, to import the certificates into the cacerts.jks file. The administrator should also update the password for the keystore.jks and cacerts.jks files, and restart the Controller to apply the changes12.

The incorrect options are:

Re-run the Controller installer and specify the new keypair. (B) This is not a valid method because the Controller installer does not allow the administrator to specify a custom keypair for the Controller SSL certificate. The Controller installer only allows the administrator to specify the Controller host name, port, account name, access key, and database settings. The Controller installer does not modify the keystore.jks or cacerts.jks files, and does not import any custom keypair or certificate into the Controller keystore or truststore3.

Upload a new keystore.jks file through the Controller UI. © This is not a valid method because the Controller UI does not provide any feature to upload a new keystore.jks file for the Controller SSL certificate. The Controller UI only allows the administrator to view and edit the Controller settings, such as the license, the security, the email, the analytics, and the EUM. The Controller UI does not access or modify the keystore.jks or cacerts.jks files, and does not import any custom keypair or certificate into the Controller keystore or truststore4.

Upload the keypair from within the Controller UI. (D) This is not a valid method because the Controller UI does not provide any feature to upload a custom keypair for the Controller SSL certificate. The Controller UI only allows the administrator to view and edit the Controller settings, such as the license, the security, the email, the analytics, and the EUM. The Controller UI does not access or modify the keystore.jks or cacerts.jks files, and does not import any custom keypair or certificate into the Controller keystore or truststore4.

As an AppDynamics Controller grows beyond supporting 500 agents, network throughput becomes more important. This is because the Controller needs to handle a large volume of data from the agents, as well as serve requests from the UI and API clients. Network throughput is the measure of how much data can be transferred over a network in a given time. A low network throughput can cause delays, errors, or timeouts in the communication between the Controller and the agents or clients. Therefore, it is recommended to monitor the network throughput of the Controller and ensure that it meets the minimum requirements for the expected load123. References: Controller System Requirements, Performance and Controller Sizing Guidelines, How to Run AppDynamics in Microsoft Azure

According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the two recommendations for servers in an Events Service Cluster are:

Should be on the same local network ©: This is a valid recommendation because the Events Service Cluster is based on Apache Cassandra, which is a distributed database that relies on network communication between the nodes. Having the servers on the same local network reduces the network latency and improves the performance and reliability of the cluster. The network bandwidth should be at least 1 Gbps, and the network firewall should allow the required ports for the Events Service Cluster12.

Should have identical hardware specifications (D): This is a valid recommendation because the Events Service Cluster is horizontally scalable, which means that the nodes share the data storage and processing load equally. Having identical hardware specifications for the servers ensures that the cluster is balanced and efficient, and avoids performance bottlenecks or failures due to hardware differences. The hardware specifications should meet the minimum requirements for the Events Service Cluster, such as CPU cores, RAM, disk space, and disk type12.

The incorrect options are:

Should be installed using the same user account (A): This is not a valid recommendation because the Events Service Cluster does not require the same user account for installation. The user account that is used to install the Events Service Cluster should have sudo privileges on the target hosts, but it does not have to be the same for all the hosts. The user account that is used to run the Events Service Cluster should have read and write permissions on the installation directory, but it does not have to be the same for all the hosts either12.

Should have eight or more CPU cores (B): This is not a valid recommendation because the Events Service Cluster does not require eight or more CPU cores for the servers. The minimum requirement for the CPU cores is four, and the recommended requirement is six. Having more CPU cores may improve the performance of the cluster, but it is not a mandatory recommendation12.

Should be running the same operating system version (E): This is not a valid recommendation because the Events Service Cluster does not require the same operating system version for the servers. The Events Service Cluster supports various Linux operating systems, such as CentOS, Red Hat, Ubuntu, and SUSE. The operating system version should be compatible with the Events Service version, but it does not have to be the same for all the hosts12.

According to the Cisco AppDynamics Professional Implementer (CAPI) documents, when updating the Database Agent, you need to follow these steps12:

Stop the agent as described for your specific installation in Start and Stop the Database Agent.

Make a copy of the existing agent directory, . Backing up allows you to revert to the previous agent installation if you need to. You can also copy over the controller-info.xml configuration file to the new installation to ensure the agent configuration is maintained.

Install the Database Agent as described for your specific installation in Administer the Database Agent.

Copy the \conf\controller-info.xml file to the new installation directory, \conf. To ensure the agent configuration is maintained, copy the \conf\controller-info.xml file to the new installation directory, \conf.

Start the new agent. See Start and Stop the Database Agent.

Verify the Database Agent Installation. See Verify the Database Agent Installation.

Therefore, the correct statements are:

The Database Agent must be stopped and restarted during the upgrade. (A)

Controller-info.xml is the only file that needs to be migrated from the previous agent to the new agent. (D)

The incorrect statements are:

If the agent is moved to a new location during the upgrade, the AppDynamics Controller must be reconfigured to reference the new location of the agent. (B) This is not true because the controller-info.xml file contains the information about the Controller host, port, account name, access key, and SSL settings. As long as this file is copied to the new agent location, the Controller does not need to be reconfigured.

All data collectors created from the previous agent must be migrated to the new agent. © This is not true because the data collectors are configured on the Controller UI, not on the agent. The agent collects the metrics from the databases and sends them to the Controller. The data collectors do not need to be migrated to the new agent.

After the Database Agent is upgraded, the AppDynamics Controller must be restarted. (E) This is not true because the Controller does not depend on the agent version. The agent and the Controller are compatible as long as they meet the Agent and Controller Compatibility requirements.

To prepare a Linux environment for the installation of an AppDynamics Controller with a Large performance profile, which is suitable for monitoring up to 1000 agents, you need to perform the following steps:

Install libaio on the host machine if it does not already have it installed. This library facilitates asynchronous I/O operations on the system, which are required by the Controller. You can use the package manager of your Linux distribution to install libaio, such as yum or apt-get. For example, on CentOS, you can run yum install libaio1.

Verify the open file descriptor limit on the system. The file descriptor limit determines how many files a process can open at a time. The Controller requires a high file descriptor limit to handle the large number of connections and transactions. AppDynamics recommends setting the file descriptor limit to at least 65535 for the user account that runs the Controller. You can check the current file descriptor limit by running ulimit -n and modify it by editing the /etc/security/limits.conf file2.

Verify the process limit on the system. The process limit determines how many processes a user can run at a time. The Controller requires a high process limit to handle the large number of threads and subprocesses. AppDynamics recommends setting the process limit to at least 65535 for the user account that runs the Controller. You can check the current process limit by running ulimit -u and modify it by editing the /etc/security/limits.conf file2.

Other steps that are not required but recommended for the Controller installation are verifying the user account permissions, configuring the virus scanners, installing the netstat network utility, and setting the NUMA configuration2. You do not need to install MySQL or Java separately, as they are included in the Controller installation package3. References: Prepare Linux for the Controller, Install the Controller on Linux, and Controller System Requirements in the AppDynamics documentation.

The EUM agent is a special agent that runs in web, mobile, or IoT applications and collects metrics on the end user experience. The EUM agent communicates with the EUM Collector, which is a component that verifies, aggregates, and packages the raw metrics sent by the EUM agent12. The EUM Collector can be either a SaaS service provided by AppDynamics or an on-premises server installed by the customer12. The EUM Collector then sends the processed metrics to the AppDynamics Controller and the Events Service for storage, analysis, and visualization12. References: Overview of End User Monitoring, EUM Data

The directory contains the EUM Server installation files, configuration files, and data files. It is recommended to back up this directory as a precaution before upgrading or migrating the EUM Server. The default location of this directory is /AppDynamics/EUM, where is the directory where you installed the Controller. You can also use the backup-eum.sh script to back up the EUM Server data12. References: Upgrade the Production EUM Server, Configure the EUM Server

In a split-host configuration, where the EUM Server and Controller are on separate hosts, the EUM Server requires access to the Controller primary HTTP(s) port. This is because the EUM Server needs to communicate with the Controller API server to send data and receive configuration information. The default primary HTTP port for the Controller is 8090 and the default primary HTTPS port is 81811. The dedicated EUM HTTP(s) ports are used by the EUM agents to send data to the EUM Server, not by the EUM Server to access the Controller2. The GlassFish administration port is used to access the Controller Admin Console, not by the EUM Server3. The Controller database port is used by the Controller to connect to the MySQL database, not by the EUM Server4. References: Controller Port Settings, Configure the Port for the EUM Agent, Access the Administration Console, Controller System Requirements

The Database Agent collects hardware metrics from a Windows database server using PowerShell1. PowerShell is a scripting language and a command-line shell that allows the Database Agent to execute commands and access Windows Performance Counters on the target host12. The Database Agent uses PowerShell to collect metrics such as CPU, memory, disk, and network utilization from the Windows database server1. To enable hardware monitoring for a Windows database server, the Database Agent requires the following permissions1:

The user that runs the Database Agent must have permission to execute PowerShell scripts on the local machine.

The user that runs the Database Agent or the Collector Service user (if using Windows Authentication) must have permission to establish a WMI connection to the target host and collect Windows Performance Counters. References: Required Monitored Host Permissions, PowerShell Overview
