INTRODUCTIONIT infrastructure is generally referred to set of a component which acts as foundation forIT services. Information technology refers to anything which is associated with computingtechnology like software, networking, internet, hardware or people who are making use oftechnology(Ajamieh and et. al, 2016). This assignment is based on Commonwealth Bank ofAustralia also known by CommBank or CBA. It is a public bank which provides banking andfinancial services. It is an Australian multinational bank which is headquartered in DarlingHarbour, Sydney, Australia. It provides its services worldwide with around 1100 branches andapprox. 4300 ATM's. This report includes geographical scope of network, three layerhierarchical model, IP addresses along with subnet mask. Furthermore, two organisations aretaken which renders cloud services, techniques of virtualisation and dynamic scaling of cloudcomputing.Task I1. Discuss geographical scope of network along with network backbone devices andcategorisation of network segments.Geographical scope of CBA (Commonwealth Bank of Australia) in given context that isthey are about to start their branch which will have 8 floors and each PC will be connected tonetwork point. As it covers small area than LAN is the best option which can be taken intoconsideration. It is explained below:Local area network (LAN):It is is defined as a computer number which is restricted to smalloffice or a building.
