Discuss Cisco 500-430 Exam Topic 4 Question 22

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

AInstall JRE.

BEnsure that MySQL port (3388) is opened.

CInstall SSH.

DInstall libaio.

EVerify that sufficient temporary (tmp) space is available (at least 1 GB).

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?

Paul 11 months ago

Definitely need libaio, can't skip that step!

Nieves 11 months ago

Wait, do we really need SSH? Seems unnecessary.

Luis 11 months ago

MySQL port needs to be open, that's a must.

Luis 12 months ago

Gotta install JRE for sure!

Marla 12 months ago

I thought SSH was necessary for remote access, but I can't remember if it's a prerequisite for the Controller installation.

Ma 1 year ago

I practiced a similar question, and I feel like verifying tmp space is important too. Did we cover that in our notes?

Rebbeca 1 year ago

I remember something about ensuring MySQL port is open, but I can't recall if that's critical for the installation.

Veta 1 year ago

I think we definitely need to install JRE, but I'm not sure about the second task. Maybe it's libaio?

Kristine 1 year ago

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.

Johnson 1 year ago

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.

Antione 1 year ago

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.

Earleen 1 year ago

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.

Lilli 1 year ago

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.

Lilli 1 year ago

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.

Hubert 1 year ago

Hmm, this seems like a pretty straightforward multiple-choice question. I'm going to go through the options and try to eliminate any that don't seem likely to be supported by the workflow page.

Hassie 2 years ago

I'm going to go with A and E. Seems like the most logical and straightforward prerequisites to me.

Let's make sure to follow those steps for a smooth installation process.

Henriette 2 years ago

↳ replying to Hassie

I agree, those are important steps before installing the AppDynamics Controller.

Jaclyn 2 years ago

↳ replying to Hassie

Yeah, installing JRE and making sure there's enough temporary space makes sense.

Nichelle 2 years ago

↳ replying to Hassie

I think A and E are the right choices.

Sue 2 years ago

↳ replying to Hassie

Yeah, those seem like the most important tasks to do before installing the Controller.

Elbert 2 years ago

↳ replying to Hassie

I think A and E are the correct ones.

Bea 2 years ago

E is definitely important too. You don't want your installation to fail because you didn't have enough temporary space.

Lourdes 2 years ago

↳ replying to Bea

E) Verify that sufficient temporary (tmp) space is available (at least 1 GB).

Lera 2 years ago

↳ replying to Bea

A) Install JRE.

Amber 2 years ago

I agree with both of you. Installing JRE and checking temporary space are crucial steps.

Eliz 2 years ago

Haha, they're really trying to trick us with that MySQL port option. Nice try, but I'm not falling for that one!

Nieves 2 years ago

Yes, that's correct. We also need to verify that we have enough temporary space available.

Alva 2 years ago

I'm a bit confused about the MySQL port requirement. Isn't the AppDynamics Controller its own separate application? Why would we need to open that port?

Mitzie 2 years ago

↳ replying to Alva

Opening MySQL port is for communication between Controller and MySQL database.

Latosha 2 years ago

↳ replying to Alva

E) Verify that sufficient temporary (tmp) space is available (at least 1 GB).

Iluminada 2 years ago

↳ replying to Alva

A) Install JRE.

Erin 2 years ago

A and D seem like the obvious choices here. You need to have the JRE installed and the libaio library to run the AppDynamics Controller on Linux.

Farrah 2 years ago

↳ replying to Erin

E) Verify that sufficient temporary (tmp) space is available (at least 1 GB).

Jamey 2 years ago

↳ replying to Erin

Yes, you're right. Those are the two preparatory tasks required.

Dong 2 years ago

↳ replying to Erin

D) Install libaio.

Alonzo 2 years ago

↳ replying to Erin

A) Install JRE.

Orville 2 years ago

I think we need to install JRE before installing the AppDynamics Controller.
