Cisco Updated 500-430 Exam Questions and Answers by benji

 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.

According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the two reasons that would require an administrator to install the Events Service cluster manually are:

• Security concerns with passwordless SSH (B): This is a valid reason because the automated installation of the Events Service cluster requires passwordless SSH access to the target hosts. Passwordless SSH allows the Enterprise Console to execute commands on the remote hosts without prompting for a password. However, some organizations may have security policies that prohibit passwordless SSH access, as it may pose a risk of unauthorized access or malicious attacks. In such cases, the administrator can install the Events Service cluster manually, by following the steps described in the Manual Installation of the Events Service Cluster document1.
• Security requirements to install using a non-root user account ©: This is a valid reason because the automated installation of the Events Service cluster requires root privileges on the target hosts. Root privileges allow the Enterprise Console to create directories, change permissions, and install packages on the remote hosts. However, some organizations may have security policies that restrict root access, as it may pose a risk of accidental or intentional damage to the system. In such cases, the administrator can install the Events Service cluster manually, by following the steps described in the Manual Installation of the Events Service Cluster document1. The administrator can use a non-root user account that has sudo privileges to perform the manual installation.

The incorrect options are:

• Installation on SUSE Linux (A): This is not a valid reason for manual installation, because the automated installation of the Events Service cluster supports SUSE Linux as one of the compatible operating systems. The Enterprise Console can install the Events Service cluster on SUSE Linux hosts using the automated installation process, as long as the hosts meet the prerequisites described in the Events Service Requirements document2.
• Installation on Windows (D): This is not a valid reason for manual installation, because the Events Service cluster does not support Windows as an operating system. The Events Service cluster can only run on Linux hosts, as it is based on Apache Cassandra, which is a Linux-based distributed database. The Events Service cluster cannot be installed on Windows hosts, either manually or automatically2.

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.

The AppDynamics Rest API to retrieve business transactions allows you to get a list of all business transactions in a business application, along with their key metrics and properties1. The correct URL format for this API is1:

• http(s) ://:/controller/rest/applications//business-transactions

The other options are incorrect because12:

• Option A uses an invalid endpoint /allbts, which does not exist in the API.
• Option C uses an incorrect base URL /controller/applications, which is used for the Controller UI, not the Rest API.
• Option D uses a misspelled endpoint /allbis, which does not exist in the API. References: Retrieve All Business Transactions in a Business Application, AppDynamics APIs
