Says IT Pros 
Must Know
With over 15 years in IT, Zuri Ozeomachukwu Njoku 
has learned that strong networking skills are key to 
building safe, reliable, and high-performing systems. 
Whether you're new to IT or already experienced, these 
six rules can help you create networks that support 
business needs and protect important data.
1. Keep Network 
Architecture Simple and 
SZucria belaliebvelse a simple, well-organized 
network is easier to manage and fix. 
When the design is clean, problems are 
less common and easier to find. She also 
says every network should be built to 
grow, so new users and devices can be 
added without causing issues or 
downtime.
2. Prioritize Security 
at Every Layer
Security should be part of every step, 
not just one. Zuri recommends adding 
security controls across the whole 
network using firewalls, access lists, 
encryption, and secure device settings. 
Regular monitoring and checking for 
weaknesses help stop threats before 
they become bigger problems.
3. Document Every 
Change Clearly
Good documentation saves time and 
prevents confusion. Zuri stresses 
writing down network diagrams, IP 
addresses, device settings, and any 
changes made during upgrades or 
repairs. Clear records make it easier for 
anyone on the team to understand and 
manage the network at any time.
4. Monitor Network 
Performance Continuously
You can’t solve an issue if you can’t see 
it. Zuri encourages using strong 
monitoring tools to watch bandwidth, 
device health, delays, and strange 
activity. Real-time alerts help catch 
problems early so the network runs 
smoothly without unexpected 
interruptions.
5. Build for Reliability 
and Redundancy
Network downtime can cost a lot. Zuri 
advises creating networks with backup 
options, extra links, failover systems, 
load balancing, and high-availability 
setups. These features keep the 
network running even if one device or 
connection stops working.
6. Keep Learning and 
Stay Updated
Technology changes quickly, and 
networks change with it. Zuri 
highlights the need for continuous 
learning through certifications, hands-
on work, and staying updated on new 
tools, risks, and best practices. 
Ongoing learning helps IT pros stay 
prepared for future challenges.
