  • Midterm: Update

    Posted by Salil Kanhere Sunday 05 July 2020, 06:29:47 PM.

    I have realised that I stuffed up a couple of answer choices for a question in the mid-term exam. I have included the question below and the correct choices which I messed up. I have updated the exam marks to reflect this error. You can check the remarked exam in Moodle. Marks also updated in the SMS database. The revised statistics are as follows.

    Max: 21.25, Min: 7.75, Mean: 15.5, Median: 15.5, Std. Dev: 3.7.

    Apologies for the error.

    Question: An organisation is granted a block of addresses with the beginning address 14.24.74.0/24. The network administrator needs to create 3 sub-blocks of addresses for 3 subnets which require 120, 60, and 10 addresses, respectively. The following sub-blocks are allocated for the first and second subnet (the beginning address of each block is provided):

    Subnet 1: 14.24.74.0/25

    Subnet 2: 14.24.74.128/26

    Which of the following could be a possible beginning address of the block for the last subnet?

    • 14.24.74.128/27
    • 14.24.192.0/29 -> Should have been 14.24.74.192/29
    • 14.24.192.0/28 -> Should have been 14.24.74.192/28 (correct answer)
    • 14.24.74.0/24
