Consider the following simplified description of deployment with hardware andsoftware load balancing and clusters. Construct a deployment diagram for the system."A network load balancer is an appliance device that is used to split network load across multipleservers. A jetNEXUS ALB-X hardware load balancer combines the functions of OSI Layer 7(Application Layer) load balancing, HTTP compression, SSL offload and content caching in onesolution. It has 2 active hardware load balancers connected to 2 to 4 Sun Fire Servers. Eachserver has 3 instances of IBM WebSphere 7 J2EE application servers installed, so we have bothvertical and horizontal clustering. When database connection is requested by application, Oraclerun-time connection load balancing selects connection that belongs to the best instance fromthe connection cache provided by Oracle RAC (Real Application Clusters) database."

Given: A network load balancer is an appliance device that is used to split network load across…

I need help in this question 2. Consider the following scenario: Either Heather attended the meeting or Heather was not invited (or both). If the boss wanted Heather at the meeting, then she was invited. Heather did not attend the meeting. If the boss did not want Heather there, and the boss did not invite her there, then she is going to be fired. Prove Heather is going to be fired using resolution inference algorithm. Show the step-by-step process of the algorithm, including the formulas in conjunctive normal form, and the derivation of each new formula leading to the proof
. Suppose a 10-Mbps Ethernet hub (repeater) is replaced by a 10-Mbps switch, in an environment where all traffic is between a single server and N "clients." Because all traffic must still traverse the server-switch link, nominally there is no improvement in bandwidth. (a) Would you expect any improvement in bandwidth? If so, why? (b) What other advantages and drawbacks might a switch offer versus a hub?
Which address on a personal computer (PC) does not change, even if the PC is moved to a different network? Justify your answer. Your answer: 2. Which OSI model layer manages communications in simplex, half-duplex, and full-duplex modes? Your answer: 3.How does the OSI reference model guarantee independence of layer functionality?

The Open Systems Interconnection (OSI) Reference Model defines seven layers that describe standards from the physical wire all the way up to the application interfaces on computers. Each layer has a specific function, common among all devices, and a specific way of communicating with the layer above and the layer below in the stack. Answer the following questions: Why is it important to wireless networking to understand the layers of the OSI Reference Model? Fully address the questions in this discussion; provide valid rationale for your choices, where applicable; and respond to at least two other students’ views. use at least two scholarly articles.
How do hubs, switches, and routers operate at different layers of the OSI model, and what are their specific functions?
