Q3:- Answer only five. Chose the appropriate terminology which expresses the following concepts: (Flow control, A token-ring Network, RTT, star topology, non-persistent HTTP, persistent HTTP, Network layer, Persistent, Interconnection, ersistent, Interconnection, bus topology, Transport services, DNS). Description NO 1 2 3 4 5 6 Terminology megrees Is a deterministic network, meaning each station connected to the network is assured access for transmission of its messages at regular or fixed time intervals. Multiple objects can be sent over single TCP connection between client, server. Allows users to exchange information (data) with other network members. All LAN data traffic is carried over a common coaxial cable link. Value used for error checking. Response time = 2RTT+ file transmission time.

You need to send a document from one computer to another, and you want it to be encrypted. Because the target computer is on a different network, data must pass via one or more routers. Ethernet is the network technology on your network, while Wi-Fi is the network technology on the target network. Should this document transfer function based on what you've learnt about networking? Why do you think that is? In the italicized sections of this description, which levels of the OSI model are involved?

Include the five most common network topologies. Which one do you think is more trustworthy?

What network topologies are allowed, and which do you recommend?

Network Analysis Exercise Please work with a few other people to answer the following question as best you can. After about 5 minutes, the class as a whole will discuss the answers. Types of network analysis: Routing (shortest route) Closest Facilities Vehicle Routing Service Areas Location-Allocation Potential Input Data: Street network / Facilities / Start Locations / End Locations / Demand Locations See Types of network analysis layers—ArcMap | DocumentationLinks to an external site. for more information about these choices Each of the following problems could be addressed using a type of network analysis. For each of them: describe what general type of network analysis it is, what input data would be necessary to run the analysis, what information about the street network would be useful to refine the analysis, and any other information/analysis that would help solve this task?

The requirements given to you for the network design are as follow:Organization consist of 8 departments. Production unit have 1800 PCs. Production unit will have further divisions of three units under its shade unit 1, unit 2 and unit 3. Every unit work as a separate work force. Creative department have 1200 PCs. Finance department will have 300 PCs. External Affairs Department will have 256 PCs. Testing unit will have 500 PCs .Like production unit, testing unit will also be divided into three subunits to test each sub production unit separately. There will be a Creative Heads department which will have 20 PCs. A restricted department that stores the confidential documents of the organization and it will have an FTP server to store files. A Board of Directors (BOD) network consists of 14 PCs. There will be some…

Addressing Schemes – SubnettingThe Iconic Production is a company newly established in the vicinity of Midrand in the city of Tshwane. The company has just hired you as their network engineer. You are told that the company currently has three departments: HR, Marketing and Operations. You are given the IP address: 192.168.5.0/24. You are required to subnet it as efficiently as possible in order to meet the requirements for the following number of hosts in the company’s network:• HR department: 13 hosts• Marketing department: 61 hosts• Operations department: 28 hosts• Link HR-M: 2 addresses• Link HR-O: 2 addresses• Link M-O: 2 addresses For each of the subnets, determine:• The Network ID• The subnet mask• The total number of hosts addresses• The number of usable host addresses• The range of usable host addresses• The broadcast addressShow all your steps and calculations and for each subnet populate the following table:Name of subnet (LAN)Network IDSubnet mask (/notation)Total number of…

Question: Design and configure a network for a company named xyz, the company has 4 Departments called IT, HR, Sales, and Guest. Each department has 10 employees but currently, only 5 PCs are connected in each department. Note: Connect Guest department as a wireless connection. Using Dynamic IP addressing. we should have ping among all devices. In a Word document create a report, document your work, and show logical and physical topology for your design. Insert the Mac address table for the switches you will use with the Mac address of the PCs. As shown below. Logical Topology here

Q4: As a network administrator for the below network, provide the suitable solution for the following:i- The DNS server consume much time for searching and retrieve information such is IP address and domain names.ii- The network will be extended to be large network so there are several changes (such us IP address and devices names), how to solve the issues of DNS configuration with these changes.iii- DNS server does not secure enough.

Course name: Networking  Question Type:  MCQ An HTTP client requests a web page with 12 (additional) objects in it. The client can only figure out that the page contains 12 objects after downloading the first object (i.e., the web page HTML content). Assume that each packet exchange with the server incurs an RTT of delay and that other processing delays (e.g., parsing the web page) are negligible.  Suppose the client uses 5 persistent connections. How many RTTs elapse until the page and its objects are fully downloaded? A: 8 B: 14 C: 4 D: 5

Assignment 1b   The following is the scope for Assignment 1b.   Response to assignment 1a   It is mandatory that students should demonstrate how they have incorporated the feedback given in assignment 1a. You may use a tabular form whenever necessary.   Network design and justification Draw a network design that you think will be useful in the future for the industry that you have visited. Network should include the following requirements: 3 routers 4 switches 10 PCs 4 VLANs. Suitable IP addressing scheme in tabular form (assume as many hosts as necessary for each department). Use 1906702 to come up with your own IP addressing scheme (to avoid Academic Misconduct). Justify the choice of IP address. Indicate where do you use static routing, dynamic routing protocols (name the protocols, RIP, EIGRP, OSPF, etc.), Access Control List (ACL) as per the network preferences. Justify your choices.   Network configuration Configure your network using Packet Tracer. Write a report on…

When it comes to wireless networks, does the term "infrastructure mode" have any bearing on the situation? What use does the network serve if infrastructure mode is not enabled? And how does this infrastructure mode differ from the one that you're searching for exactly? Is there a reason for the person who administers the network to be concerned about this?
