Problem Explanation of Proposed Solution Group A-D – Subnet addresses need corrected all should be 255.255.0.0 Correct the subnet addresses for group A-D by changing the subnet address on computer A to be the same as B‚C. Then correct D to match B&C. Router1 – the IP Addresses should match the network they flow from. IP Address flowing

OSI vs. TCP/IP Model Comparison & Overview The Open Systems Interconnection (OSI) reference model created in the late seventies and used today consists of seven layers that include Application‚ Presentation‚ Session‚ Transport‚ Network‚ Data Link and Physical. The Application layer often dubbed Layer 7 is the most common layer to end users and can consist of applications such as Microsoft’s Internet Explorer or other browser software. The Presentation layer provides a translation of application

Networking Topologies and TCP/IP protocol Bus Topology It just doesn’t get much simpler than the physical bus topology when it comes to connecting nodes on a Local Area Network (LAN). The most common implementation of a linear bus topology is IEEE 802.3 Ethernet. All devices in a bus topology are connected to a single cable called the bus‚ backbone‚ or ether. The transmission medium has a physical beginning and an end. All connections must be terminated with a resistor to keep data transmissions

of an IP address does which of the following? The subnet mask defines network and host portions of an IP address. 3. If a protocol is routable‚ which TCP/IP layer does it operate at? A routable protocol operates at the Internetwork layer of TCP/IP. 4. Which of the following is a private IP address and can’t be routed across the Internet? The IP address 172.19.243.254 falls within one of the IP address ranges reserved for private uses by Internet standards groups. 5. Which TCP/IP model

attempting to get industry participants to agree on common network standards to provide multi-vendor interoperability. It was common for large networks to support multiple network protocol suites‚ with many devices unable to interoperate with other devices because of a lack of common protocols. However‚ while OSI developed its networking standards‚ TCP/IP came into widespread use on multivendor networks for internetworking; while on the local network level both Ethernet and token ring gained prominence

TCP/IP LAN Check Point #8 Answer: C Explanation: The network address 150.50.0.0 that was originally assigned is a class B‚ so it has a default subnet mask of 255.255.0.0. Then you need to divide this network into 7 subnets and only the net work address 255.255.240.0 provides enough networks because it will provide 16 - 2 = 14 subnets (-1 for the network address and -1 for the broadcast address‚ which gives a -2 from the total of subnets). #9 Answer: C Explanation: The network address 209
