Criticize my topology

RouterOS Beginner Basics
1

Hello guys. I need your help. (In some places I will use a translator because my English level is not as perfect as I would like, please forgive me in advance for this: 3 )

The fact is that I started working with mikrotik equipment not so long ago, and I’m still studying to become a system administrator. I was faced with the task of modernizing the entire network at the enterprise. I studied the issue through long sleepless nights and came to the following scheme and the choice of equipment. I am very much asking for criticism and constructive advice from you.

Whether I chose the main router correctly. Will he cope with the upcoming load, and so on. I apologize for the scarcity of incoming data. But if something is needed, I will immediately add the necessary information. Thanks!

Howmany & what cabling do you have between BUILDING 1 / 2 / 3
What are you requirements towards resilience / redundancy ?

Dear friend,

I am not a specialist, but your topology has one point of failure : the main router.
You could think of redundancy and build direct links between the three networks so that if the main router is dead, the networks are still interconnected.

Kind regards,

The biggest question is how much traffic will this network need to handle. What I mean by that is for example, how fast is the internet connection? How many client devices will there be? Will clients be WiFi or wired. Will the clients be primarily communicating with the internet or with local services? How much traffic will the clients be needing (for example, 100 people watching YouTube will need far more bandwidth than 100 people reading E-Mai).

The 2nd 48P on each building is for?

Fiber-optic cable between buildings
I am counting more on redundancy, for the possibility of further expansion of the network

150Mbit now
the expansion to 500 is planned in early 2022

Between 170-250 wired clients. And ~70-100 Wi-Fi clients.

Both

Ordinary office users with their routine tasks

For fiber-optic connection to main router.

I do not understand, the 1st already do not do that?



Use two CRS328-24P-4S+RM instead to one CRS354-48P-4S+2Q+RM

Instead of one main CCR1036-8G-2S+EM, put one CCR1016-12S-1S+ for building
and one CRS305-1G-4S+IN where is the ISP gateway for share ISP betwen the 3 CCR1016-12S-1S+

Place separate CAPsMAN for each building.

I am confused,
If you are studying to be a system administrator, why are you in charge of this project.

I think it would be more accurate to state this clealry as
as part of my system admin course we have to design a network with these requirments.

Then state exactly where you are having problems with your planned design in very specific terms.
Asking us to solve your entire HOMEWORK problem and design your system is not the purpose of this forum.
