Draw a diagram of all machines and devices in the School of Engineering$$s LAN. Clearly label all $2$nd$$and $3$rd$$layer devices that will be needed to provide internal and external connectivity; all subnets in the building should be clearly identified in your diagram.

Ground floor

$4$ Computer$$labs $(70$ sq$.$ m$.$ each$)$

Each lab has capacity of $30$ students$$: $20$ desktops and $10$ hot desks for personal, mobile machines$$

A lectern with a desktop machine, an IP telephone$$and a projector for the TA in each lab$$

$4$ specialised labs $(70$ sq$.$ m$.$ each$)$

$20$ student capacity$$

Up to $10$ desktop computers in each$$

Students can bring their own machine$$

A lectern with a desktop machine, an IP telephone and a projector for the TA in each lab$$

The Tesla Lecture Theatre has a seating capacity of $150$; area: $216$sq$.$ m$.$

It has a lectern with a desktop machine, IP telephone and a projector$$

$$The lobby and hallway will be fitted with scattered seating and tables.

One networked multifunction printer for students and staff.$$

First floor

$30$ individual offices for the School academics equipped with desktop machines and IP telephones$$

$2$ shared offices $(6$ desks in each$)$

$2$ meeting rooms$$

$3$ school admin offices$$equipped with desktop machines and IP telephones$$

One networked multifunction printer for staff and postgraduate students.$$

You can assume that all offices on the $1$st$$floor and all desks and lecterns in the labs have been provided with ethernet cabling.$$

There are no local servers. Any servers required by the School will be located$$within the campus data centre, in a different building. Physical layer connectivity to the campus data centre has been already provided via high bandwidth cabling. Part of your design should include any necessary devices within the School building to enable that.

You must draw a diagram!
