- Summarise the main points in this module. Make sure that you include references to the learning objectives.
- How is this useful?

- Reflecting on the content
Provide a reflection by answering the following questions:
- What is the most important thing you learnt in this module?
- How does this relate to what you already know?
- Why do you think your course team wants you to learn the content of this module?

2. Evidence of Learning
Provide evidence of your work on this module. This can contain notes that you took, activities and analyses you have done in the active classes rated to this module, and any other work that you produced. You can take screenshots of your analyses and simulations and include in here. If you have developed an application/ program (for example using Python), then please also provide the code along with the submission labelling the code. If you used external resources in your learning, please include links to them. Please also make sure to include short comments together with your evidence. You can,

• Provide references to activities that you have done to highlight your learning on the key learning objectives of this module and active class. Make sure that you provide evidence for the all the activities you have done in the relevant Active Classes.
• Provide references to any specific content that you found difficult, how you overcame these difficulties, and what you learnt from them.
• Include questions where you made mistakes and comment what you learnt from those mistakes, or how you overcame them.

1. Evidence of self-assessment, with a sufficient score.

Please include evidence that you reached the minimum required score at the self-assessment. On the results page of the self-assessment, you can use print/ save page as pdf option in your browser to save the results into a pdf file. You can then upload this file as your evidence.

Task 6.2C

As you are targeting above the pass grade, you will be expected to gain deeper understanding of the topics we cover in this unit, going above and beyond in your learning journey. For this credit task, you will be developing a DNS server using Python.

Task Requirement

Present evidence that you have been able to develop the DNS server according to the instructions provided. You need to submit your summary and reflections on your learning & evidence to OnTrack.

Task Instruction
For this task, you will build a DNS server using Python. Your DNS server must have the following features and functionality.
• As we have learnt in Module 2, DNS uses UDP as the transport layer protocol.
• Uses the query and response messages.
• Capable of supporting two types of resource records, A and CNAME.
• Capable of supporting Hostname-to-IP-address translation and host aliasing.
• The server must display a message on the terminal when it is started to indicate it is running.
You must also build a client program to test the DNS server. The client program must be able to provide the hostname /alias name in the terminal and send a DNS query to the server. The client process must display the response received from the server in the terminal. Client program should also prompt the user to check whether the user would like to continue with another DNS query or not.

Task 5.2D

As you are targeting above the pass grade, you will be expected to gain deeper understanding of the topics we cover in this unit, going above and beyond in your learning journey. For this distinction task, you will be expected to demonstrate your deeper understanding of six core modules (except Module 1) that you complete in this unit. In your credit task, Task 4.2C, you demonstrate your deeper understanding of topics we cover in three core modules. In this task, you can include what you have included in Task 4.2. In addition, you will be expected to demonstrate your deeper understanding of the rest of the core modules you complete in the unit. Altogether, in this task, you will be expected to demonstrate your deeper understanding of six core modules (except Module 1).

Task Requirement
Present evidence that you have been able to gain deeper understanding of the content you complete in six core modules of the unit along with a summary and a reflection that indicate how you have demonstrated deeper understanding of the chosen modules.
You need to submit your summary, reflections, and evidence to OnTrack.

Task Instruction
For this task, we want you to demonstrate that you have been able to use what you have learnt in the unit to extend your knowledge on the chosen topics. You can go above and beyond in completing more activities in addition to what you have completed in module exercises and active classes relevant to each module. In this task, you need to provide a summary, reflection, and evidence on your deeper understanding of the topics. The evidence can contain the additional activities and analyses you have done, and any other work that you produced. You can take screenshots of your analyses and simulations and include in here. If you have developed an application/ program (for example using Python), then please also provide the code along with the submission labelling the code. Please make sure to include a separate summary, reflection, and evidence for each module that you include in this task.
