Problem Based Learning (PBL) Exercise
Tutor will provide instructions on the requirements of the PBL and submission guidelines.
There will not be any solutions provided to any of the PBL exercise, as solutions defer. Problem Based questions are open-ended to allow students to think critically, analyse and provide solutions based on their understanding. Make sure solutions should be concise and address each point specific to in-depth technical knowledge.
However, tutors will provide feedback during each class.
All PBL classes are based on flip-learning.
"The flipped classroom describes a reversal of traditional teaching where students gain first exposure to new material outside of class, usually via reading or lecture videos, and then class time is used to do the harder work of assimilating that knowledge through strategies such as problem-solving, discussion or debates.
Week 1 Exercise:
XYZ company is planning to have a network of 18 luxury hotels which are located on three continents, in locations such as Hong Kong, London, Geneva, Bermuda, Bangkok and Singapore.
Discuss on the following topics:
- What type of network can be designed?
- What are the networking devices to be used?
- What type of cables to be used?

3. LAN Network design with redundancy
Project Scope
A network which has redundancy in the design to be setup for an organization. The organization is currently having an internet connection, which is setup using a Cisco router. The gateway addresses for users in the LAN is currently provided as an intermediate routers address, which would then forward all internet bound packets to the internet router. The network has to be upgraded by having dual intermediate routers which would automatically failover, and provide high availability access to the internet. HSRP is to be used for the deployment. The project identifies the configurations required on Cisco routers to achieve the same.

5. Remote access VPN Network design behind NAT router
Project scope and description
In this project, a network has to be designed for remote access VPN. A windows XP VPN server is to be setup behind a Cisco NAT router.
The NAT router has a public IP address received dynamically by the ISP, which is also required to be used by the LAN users for internet. The remote users should be able to connect to the public IP address of the router, and establish connectivity with the VPN server. After connection is established, the remote user should be able to access systems on the LAN. LAN and VPN network should be segregated using appropriate VLAN's
