Question No. 1

Which directory should an administrator back up if the goal is to back up the EUM Server?

Show Answer Hide Answer
Correct Answer: A

The <eum_server_home> 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 <installDir>/AppDynamics/EUM, where <installDir> is the directory where you installed the Controller.You can also use the backup-eum.sh script to back up the EUM Server data12.Reference:Upgrade the Production EUM Server,Configure the EUM Server


Question No. 2

What becomes more important as an AppDynamics Controller grows beyond supporting 500 agents?

Show Answer Hide Answer
Correct Answer: C

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.Reference:Controller System Requirements,Performance and Controller Sizing Guidelines,How to Run AppDynamics in Microsoft Azure


Question No. 3

What are two actions that an administrator should take to upgrade an EUM Server that is currently in production? (Choose two.)

Show Answer Hide Answer
Correct Answer: D, E

To upgrade an EUM Server that is currently in production, the administrator should follow these steps:

Stop the EUM Server before the upgrade. This ensures that the EUM Server does not process any incoming data from the EUM agents during the upgrade process.The administrator can use theeum.shoreum.batscript to stop the EUM Server gracefully1.

Run the new installer on the EUM host machine. The installer will detect the existing EUM Server installation and prompt the administrator to upgrade it to the latest version. The installer will also migrate the EUM data from the old version to the new version, if needed.The administrator should follow the instructions on the installer wizard to complete the upgrade2.

The other options are not necessary or correct for upgrading the EUM Server. The administrator does not need to stop or upgrade the EUM agents, as they are compatible with the new version of the EUM Server. The administrator does not need to update the EUM Server access key, as it remains the same after the upgrade.The administrator does not need to install MySQL, as it is bundled with the EUM Server installation package2.Reference:Upgrade the Production EUM ServerandStart and Stop the EUM Serverin the AppDynamics documentation.


Question No. 4

What are three recommended steps to prepare a Linux environment for the installation of an AppDynamics Controller with a Large performance profile? (Choose three.)

Show Answer Hide Answer
Correct Answer: A, D, F

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 runyum 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 runningulimit -nand modify it by editing the/etc/security/limits.conffile2.

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 runningulimit -uand modify it by editing the/etc/security/limits.conffile2.

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.Reference:Prepare Linux for the Controller,Install the Controller on Linux, andController System Requirementsin the AppDynamics documentation.


Question No. 5

Which implementation mode should be used when deploying an EUM Server with reverse proxy from a security and performance standpoint in a production environment?

Show Answer Hide Answer
Correct Answer: D

The EUM Server is the on-premises version of the EUM Cloud that receives, processes, and stores data from EUM agents. For production installation, AppDynamics recommends that the EUM Server and the Controller sit on different hosts, and the EUM Server hosts its own MySQL instance. This improves the scalability and performance of both components. Moreover, AppDynamics strongly recommends that SSL traffic from agents to the EUM Server is terminated at a reverse proxy that sits in front of the EUM Server in the network path, and forwards connections to the EUM Server using HTTP. This relieves the SSL processing load from the EUM Server, simplifies the certificate management, and enhances the security by isolating the EUM Server from the external Internet. Therefore, the best implementation mode for deploying an EUM Server with reverse proxy in a production environment is option D.Reference:EUM Server Deployment,Install a Production EUM Server,Reverse Proxy configuration for EUM, andBrowser EUM installationin the AppDynamics documentation and community.
