Question 1

• 
• I incorrectly selected answer D when the the correct answer was option C as the algorithm doesn't work with the selected step as remainder needs to be decided and the quotient stored to properly make the program function this was a result of not being able to understand the calculations

Question 2

• 
• I incorrectly selected answer A when the correct answer was answer C as the selection would not allow the bot to move to the correct location but option C would allow the bot to be able to move the needed amount of spaces to the right location this was due to not properly evaluating the options.

Question 3

• 
• I didn't know the nature of IPv6 addresses so I guessed a random choice in fact the correct answer is that the address is longer and thus allows for more connected devices on the internet thus the correct answer is option B

Question 4

• 
• I selected option C as through not understanding what a certificate authority does the correct answer is option D as the authority verifies encryption keys

Question 5

• 
• I incorrectly selected option B as the second answer when in fact it was option D, the selection of option A was correct the reason option B was incorrect was line 8 needs to be there and line 11 incorrectly adds to the count variable this was correctly determined when reasoning but I mis-selected the answer.
