- Suppose that the WFQ scheduling policy is applied to a buffer that supports three classes (of priority packets), and suppose the weights are 0.25, 0.5, and 0.75 for the three classes. Further suppose that each class has a large number of packets in the buffer. In what sequence might the three classes be served in order to achieve the WFQ weights?Sort DNS records according to their kind. Briefly describe each one with examples and explain why they are employed. Is it conceivable for a web server and a mail server in an organization to have the exact same alias for a hostname?Sort DNS records according to their kind. Give a short description of each with examples, as well as an explanation of why they are utilized. Is it feasible for a web server and a mail server in an organization to use the same alias for a hostname?
- It is important to keep in mind that the reordering and reassembly of packets takes place during the transport step of the TCP/IP protocol suite. The Internet or the data layer are two examples of lower levels of abstraction that a firewall is able to function at. If a traffic stream is either out of order or has been deleted, a firewall that uses stateful inspection will be unable to determine anything about the stream's contents.Are the TCP receive buffer and the client's application buffer same when utilizing HTTP streaming? How do they engage with one another if they don't talk to one another?Data collision occurs when many senders access the same media at the same time; which protocols and whose Layers are available to manage this issue? Is it possible to use these protocols without worrying about a loss of data due to collisions? In the event that this does not work, what other solutions are available?
- We may evaluate the two modes of cypher encryption, cypher block chaining and cypher feedback mode, by looking at how many encryption operations are needed to transport a large file.To what extent is the more efficient option preferred?When a web client requests access to protected resources on a web server, show the step-by-step implementation of native authentication and authorization services. What are the two most compelling arguments for using layered protocols? Give instances to back up your position.When a web client requests access to protected resources on a web server, show the step-by-step implementation of native authentication and authorization services. What are the two most persuasive arguments to adopt layered protocols? Give instances to back up your position.
- Demonstrate the step-by-step implementation of native authentication and authorization services on a web server when a web client requests access to protected resources on the server. What are the two most compelling arguments in favor of using layered protocols? Give specific instances to support your point.Compare the number of encryption operations necessary to transfer a large file using cypher block chaining versus the amount of encryption operations required using cypher feedback mode.Which one is more effective, and by what margin is it more effective?You have the option of categorizing DNS records by category. Every single one of them has to be segmented into manageable pieces and accompanied with examples and arguments. Is it possible for an organization's email server and web server to have the same hostname?
