Explain (Arabic) two chapters only with Data Center Topologies

I would like to explain two chapters only with Data Center Topologies

Do you understand this article and do explanations work??

I sent the two young men

And I want to explain today in the afternoon, so can you?

And the explanation is only a recorded video

And I want you to give me the lowest, lowest, lowest price, because I deal with you and have more than 5 explanations per week

Note: The explanation is in Arabic only
