OSA Summer 2023 Mock - Task 3, Assignment 1
OSA Summer 2023 Mock – Task 3
KJ eLearning technical proposal
To conduct normal business operations and supply education to technical and non-technical adults, KJ eLearning must have a fast and reliable network. To create this digital environment, capable hardware must be installed to facilitate the amount of traffic and learners using it.
The company is looking to expand its workforce from 10 full time staff to 20 over the next 12 months. This means that high performance communication equipment must be installed to run the network reliable and allow stable data transmission.
Switches
Switches allow for data packets to be directed across a LAN to other endpoints. Switches use mac addressing to determine which host is receiving the data and avoids broadcasting the data like a hub, which is less secure due to the risk of a man-in-the-middle attack. Due to the expansion of the business premises and the planning of 3 new classrooms all which require network and power connections to each desk, there will need to be multiple switches implemented. This will also allow for further expansion when the new staff are inducted and features such as POE for CCTV camera implementation.
The switches would be configured such as this. The main (core) switch is directly connected to the servers whilst the 3 other switches are separated using VLANs.
VLAN1 – Used for desktop connectivity for staff and learners in the premises.
VLAN2 – Used for the CCTV network, enabling all cameras to be connected using PoE.
VLAN3 – Hosts the wireless network across the premises and connects the wireless communication equipment.
The reason for segregating the network using VLANs is because it is easier to manage and troubleshoot issues. It also increases network security as traffic is isolated from other traffic on the network.

Main (core) switch
The Ubiquiti standard 24 port switch is a powerful switch which will be capable of handling traffic from the servers without causing a bottleneck on the network. It has 24 GbE RJ45 ports capable of 26Gbps and a switching capacity of 52 Gbps. The additional ports would also allow for further expansion if the business were to need more network connections. It is ideal for medium to large enterprises and a very reliable core switch.
Switch01 and switch02
Switch01 and 02 will be Ubiquiti Pro Max 48 port switches. These are highly capable, and they will become the main switches for desktop connectivity in the classrooms and for staff. They each have 32 GbE RJ45 ports, 16 1/2.5 GbE RJ45 ports and 4 10G SFP+ ports. The total throughput of this switch is 112Gbps, allowing for reliable and fast connections. These switches will allow for learners and staff to connect to the network and share resources without any delays or performance decrease.
Switch03
Switch03 will be a Ubiquiti Pro 24 port PoE capable switch. This switch will provide network and power to devices such as internal CCTV cameras, external CCTV cameras and wireless access points. By separating PoE devices onto a separate switch, troubleshooting and network maintenance is made easier and controlled. This switch has 16 PoE/PoE+ ports and 8 60W PoE++ ports allowing for all the devices to be connected reliably. The total throughput of this switch is 44Gbps, suitable for connecting these devices to the network without performance drops.
Switch installations
All the switches will be installed in the server room due to the availability of air conditioning and the installed gas suppression systems. This will allow the switches to remain cool whilst being in a centralised place and easily accessible.
Access points
Access points allow for the wireless local area network (WLAN) to be spread across the premises and allow users to connect to it. Due to the size of the premises and the planned expansion of staff, 3 access points should be installed in strategic locations to provide coverage over all the devices.
Access point | Location | Coverage | Notes |
AP01 | Main hallway between rooms 1,2 and 3 | Room 1 Room 2 Room 3
| Ubiquiti U7 Pro Max. |
AP02 | Main hallway between reception and W/C | Server room W/Cs Reception Public waiting area
| Ubiquiti U7 Pro Max.
|
AP03 | Main hallway between administration office and classroom 1
| Classroom 1 Administration office Meeting room | Ubiquiti U7 Pro Max. |
AP01, AP02 and AP03
All the access points will be Ubiquiti U7 pro max APs. These access points are powered by PoE+ and will be connected to switch03. They have speeds of 8.6Gbps on 5 GHz which is more than enough to provide sufficient network capabilities to staff and learners. They also support WPA-PSK which allows for secure and encrypted transmissions. Their coverage is 160m^2, allowing for full coverage of the building with a wireless network solution. Each AP supports Wi-Fi 7 and allows 500+ connections.
Access point installations
To provide full coverage of the building, 3 access points should be ceiling mounted to provide the best coverage on the premises. Theoretically, anywhere someone goes in the building will be covered by the wireless network allowing for increased productivity and network accessibility.
CCTV
To deter and defend against physical threats to the premises, CCTV cameras will be installed internally and externally. All cameras will be connected and powered simultaneously by PoE to switch03. An NVR will also be installed to record and manage video recorded by the cameras placed around the premises.

Cameras
Most of the internal cameras will be Unifi G5 Bullet IP cameras. It has a 4MP camera that shoots at 30FPS, capable of recording activity in high definition.
CAM04 will be a Unifi AI dome camera. This camera is capable of pivoting to capture multiple angles which makes it a suitable fit for the hallway. It has an 8MP camera that shoots at 30FPS, capable of recording activity in high definition. It also has AI tracking capabilities, enabling it to identify and track threats inside the building.
The external cameras will be Unifi AI LPR cameras. This is due to their weatherproof IP66 rated enclosure enabling it to withstand and function in extreme weather. It has an 8MP camera that shoots at 30FPS, capable of recording activity in high definition.
Network video recorder
The network video recorder used is the Unifi UNVR. This NVR has a 1 GbE RJ45 port and 1 1/10 GbE SFP+ port. It has capacity for 60 HD cameras, which gives the business flexibility for upgrades or adding additional cameras in the future.
