Which two preparatory tasks are required prior to installing an AppDynamics Controller on Linux? (Choose two.)

Show Suggested Answer Hide Answer
Suggested Answer: D, E

Before installing an AppDynamics Controller on Linux, you need to perform some preparatory tasks to ensure the system meets the requirements and the installation runs smoothly. Two of these tasks are:

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 that you have enough temporary (tmp) space available on the system, at least 1 GB. The Controller installation uses the tmp space to extract and install the software components.You can check the tmp space by runningdf -h /tmp2.If the tmp space is insufficient, you can either free up some space by deleting unnecessary files, or specify a different temporary directory for the installation by passing the-Djava.io.tmpdirparameter to the installer3.

Other preparatory tasks include verifying the user account permissions, configuring the virus scanners, installing the netstat network utility, and setting the file descriptor limit2.Reference:Prepare Linux for the Controller,Install the Controller on Linux, and [Controller System Requirements] in the AppDynamics documentation.

1 GB of tmp space? That's a lot! Are you sure?

I'm pretty confident the right answers are A and E - installing JRE and verifying temp space. The other options don't seem directly relevant to the Controller installation.

Wait, what's the MySQL port requirement about? That seems a bit odd for just installing the Controller. I'll double-check the details on that one.

Okay, I think I've got this. Install JRE and verify sufficient temporary space - those seem like the key preparatory tasks based on the options provided.

This looks straightforward. I'll start by checking the options and seeing which two make the most sense for preparing to install the AppDynamics Controller.

Hmm, I'm not too familiar with AppDynamics, so I'll need to read through the options carefully. Installing JRE and libaio seem like they could be important prerequisites.

I've got a good feeling about this one. The VLANs listed in option A sound familiar to me, so I'm going to go with that. Hopefully, my memory serves me well on this FortiSwitch question.
