Highlights
Question 1
From the grades in your Cisco NetAcad gradebook (look in the grades section), calculate your average grade for Introduction to Networks – module sprints 1-3, 4-7, 8-10 (i.e: 3 tests in all) and submit the calculated result as your answer to this question. The calculation you must use and fully show in the TMA is:
- gradeAverage = (M1>3 + M4>7 + M8>10) / 3
- questionScore = (0.2 × gradeAverage)
If the questionScore is a decimal (not a whole value), then you may round it up to the next nearest whole number (e.g. 17.2 will become 18). For example:
- M1>3: 81
- M4>7: 79
- M8>10: 67
- gradeAverage is (81 + 79 + 72) / 3 = 77.33 (to 2 decimal places)
- questionScore is (0.2 × 77.33) = 15.46
Note: always round up to the next whole number. Therefore, rounded up, the final mark is 16.
Question 2
Draw an annotated simple diagram representing an encapsulated TCP PDU, clearly showing the data elements involved in a web server HTTP request. You are expected to explore alternate sources to create this simple diagram – you are not expected to cite these.
Question 3
This question allows you to demonstrate your ability to work with the hexadecimal (hex), binary and denary numbering systems. Which is covered in module five (Number
Systems). In each case you must show your working to gain full marks. By all means use a calculator to check that your answers are correct, but it will be very useful for you to be able to manipulate these types of numbers without using a calculator.
a. Convert the following binary MAC address to hexadecimal form. Please show your working; failure to do so will only gain up to half marks:
11000001-01011100-00001101-00010101-11000000-01010111
b. Convert the following binary IP address to dotted decimal form as shown in module 5. Show your working; failure to do so will only gain up to half marks. 01100011.01000010.00100001.00000001
c. Convert the following IP address into binary. Show your working; failure to do so will only gain up to half marks. 192.168.100.5
d. For the following IPv6 address, identify the address type and write the address in compressed format.
