A real-life scenario and the lab environment your college could adopt
Troubleshooting and problem-solving skills are one of the most fundamental skills in the IT industry, which can apply in IT work on a daily basis. IT experts use these skills to determine the type of network problems in order to take accurate and prompt action. Therefore, when students graduate from a college and are ready to face the real work challenges in the IT industry, troubleshooting skills are essential and will come into play.
To help colleges easily adopt the unit ICTNWK308 in Certificate III in Information Technology ICT30120 , eduLAB has prepared a real-life scenario along with the eduLAB portal and possible activity suggestions where students are able to participate in determining and taking actions to resolve network problems.
Skills that students can learn and master in ICTNWK308 are beneficial in careers such as:
- Helpdesk & IT Support Technician
- Systems Administrator
- Infrastructure & Network Engineer
- Security & Support Engineer
- Infrastructure Solution Designer
Maxmit Pty Ltd is a small pharmaceutical research company with 15 staff members. Its IT infrastructure is small, consisting of an Active Directory with a file server, and a proxy firewall that protects staff computers against malicious and inappropriate websites.
The company executives have decided to hire an IT Support Technician to help them with day-to-day issues and bring stability to their IT infrastructure. Recently, there have been complaints from staff members as they could not access the internet. Additionally, there is a list of outstanding IT issues that incapable of being resolved internally.
To resolve the issues, the IT Support Technician must stabilise the IT infrastructure by going through the outstanding IT issues and solve them. Then finally, revises the website content filtering rules and apply changes as per the company’s IT policy.
