Network Engineer-AI-powered network optimization tool

Example

Designing a scalable and redundant network topology for a multi-site enterprise.

Scenario

A financial company with multiple global offices requires a secure and resilient network to connect its sites. The Network Engineer designs a hybrid WAN solution using MPLS and SD-WAN, with VPN backups for redundancy. The design includes firewall policies, network segmentation, and optimized routing for efficient traffic flow across all branches.

Example

Diagnosing and resolving a network outage affecting an organization’s internal applications.

Scenario

A hospital’s network experiences intermittent connectivity issues, affecting access to critical healthcare applications. The Network Engineer uses network monitoring tools like Wireshark and SolarWinds to isolate the root cause—a faulty switch. They replace the hardware and reconfigure it to restore full functionality and improve performance.

Example

Tuning Quality of Service (QoS) policies to prioritize real-time communication applications.

Scenario

An e-commerce company faces latency in their VoIP systems during peak hours. The Network Engineer implements QoS policies on the network to prioritize voice traffic over less critical data, ensuring uninterrupted, clear communication during busy periods.

Example

Deploying firewalls and Intrusion Detection Systems (IDS) for improved network security.

Scenario

A government agency requires strict security policies due to the sensitive nature of their data. The Network Engineer configures advanced firewall rules and deploys IDS/IPS systems at critical network points to detect and block potential cyber threats, ensuring compliance with security standards.

Example

Continuous monitoring of network health using NMS (Network Management System).

Scenario

A large university needs to ensure reliable connectivity for students, faculty, and administrative staff. The Network Engineer sets up automated monitoring systems like Nagios or PRTG to monitor network performance in real-time and alert the IT team in case of any issues. This proactive approach helps prevent downtime and maintains high availability.
