Question 1

What is NCEA AS 91642 about?

Accepted Answer

You'll set up a small Wide Area Network (WAN) by assembling and configuring the hardware and software, then test it to make sure it works properly. You'll also learn how to manage it day-to-day and fix problems when things go wrong—like incorrect cables or IP addressing issues. This is about getting hands-on experience with real networking equipment and the procedures professionals use.

Question 2

What do students need to do for AS 91642?

Accepted Answer

1. Assemble and configure a WAN using physical components (switches, routers, cables, PCs) according to given requirements 2. Test the WAN using standard tools like ping, ipconfig, and tracert to verify it's working correctly, and document your results 3. Manage IP addressing, DHCP settings, NAT, router security, and backups using standard admin procedures 4. Diagnose and troubleshoot network faults—such as faulty cables, wrong IP schemes, or misconfigured devices—and fix them 5. Work independently and accurately to complete these tasks with minimal supervision

Question 3

What's the difference between Achieved, Merit, and Excellence for AS 91642?

Accepted Answer

Achieved: You follow all the standard procedures to build, test, and manage a small WAN, and you can troubleshoot and fix the faults you're given. Merit: You work with accuracy and independence, following admin procedures skillfully and diagnosing/fixing faults without needing guidance. Excellence: You complete all procedures in a way that is economical with time, effort, and resources—working smartly and efficiently throughout.

Question 4

What mistakes do students typically make in AS 91642?

Accepted Answer

1. Not documenting test results properly—you must record what you tested and what the results show to prove the WAN works 2. Missing or incomplete troubleshooting steps—examiners expect to see clear evidence of how you identified and resolved each fault, not just that you fixed it 3. Incomplete IP addressing or DHCP configuration—many students set up basic connectivity but skip important admin procedures like NAT, router security, or config backups
