$1.$ Using a packet analyzer tool $($e$.$g$.,$ Wireshark, packet tracer$),$ capture

a set of packets from a network activity $($such as visiting a website$).$

Analyze the captured packets to:

a$)$Identify the protocols used at each OSI layer.

b$)$Explain the role of each identified protocol in the data

communication process.

c$)$ Highlight any findings that indicate how Layer $3($Network

Layer$)$ routing decisions are made.

d$)$Discuss how Layer $4($Transport Layer$)$ protocols ensure data

integrity and order.

$2.$ You are provided with a network topology and a list of symptoms

indicating network issues, such as slow internet connectivity,

inability to access certain network resources, and intermittent

connectivity problems. Your tasks are:

a$)$Diagnose the issues based on the symptoms and the

provided network topology.

b$)$Identify potential causes for each symptom.

c$)$ Propose solutions to resolve the identified issues.

d$)$Implement the solutions on a network simulator and test

the network to ensure that the issues are resolved.
