Senior Network Engineer Assessment Test

A Senior Network Engineer Assessment Test evaluates individuals on their advanced knowledge and skills in designing, implementing, managing, and troubleshooting complex network infrastructures. Senior Network Engineers are responsible for maintaining network performance, ensuring security, optimizing resources, and supporting large-scale enterprise environments.

A Senior Network Engineer Assessment Test evaluates candidates for:

• Proficiency in networking protocols, including TCP/IP, UDP, ICMP, DNS, and DHCP, and understanding the OSI and TCP/IP models for data transmission across networks.
• Skills in subnetting and IP addressing, including IPv4 and IPv6 networks, subnetting, supernetting, and using CIDR (Classless Inter-Domain Routing) for efficient IP allocation and routing.
• Proficiency in routing protocols such as OSPF, EIGRP, BGP, and RIP, understanding the configuration and troubleshooting of dynamic routing protocols in enterprise environments.
• Experience with Layer 2 switching, including configuring VLANs, VTP (VLAN Trunking Protocol), and STP (Spanning Tree Protocol) to manage network segmentation and prevent loops.
• Proficiency in managing switch configurations, including 802.1Q trunking, EtherChannel, port security, and QoS (Quality of Service) settings to optimize network performance and security.
• Skills in configuring high availability (HA) and redundancy protocols, including HSRP (Hot Standby Router Protocol), VRRP (Virtual Router Redundancy Protocol), and GLBP (Gateway Load Balancing Protocol) to ensure network uptime and failover.
• Proficiency in advanced routing, such as route summarization, policy-based routing (PBR), and redistribution between routing protocols for efficient routing in complex networks.
• Experience with firewalls, including configuring firewalls (e.g., Cisco ASA, Palo Alto, Fortinet), creating Access Control Lists (ACLs), and managing advanced firewall features like deep packet inspection and SSL decryption.
• Proficiency in VPN technologies, configuring IPSec, SSL VPNs, and site-to-site VPNs for secure remote access and connectivity between multiple locations.
• Skills in managing network intrusion detection and prevention systems (IDS/IPS), configuring tools like Snort, Suricata, or integrated IDS/IPS systems for network threat detection and prevention.
• Proficiency in using network monitoring tools, such as Wireshark, SolarWinds, PRTG, Nagios, or Cisco Prime, for tracking network performance and identifying issues.
• Skills in troubleshooting networks, using commands like ping, traceroute, netstat, and tcpdump, and managing SNMP for diagnosing network problems, such as packet loss, latency, and configuration errors.
• Experience with wireless networking, configuring and managing WLAN controllers and access points (e.g., Cisco, Aruba, Ubiquiti) and understanding 802.11 wireless standards.
• Proficiency in wireless security protocols, including WPA2, 802.1X, and RADIUS, to ensure secure wireless communications in enterprise networks.
• Proficiency in cloud networking, configuring virtual networks in AWS, Azure, or Google Cloud, including VPNs, Direct Connect, and Virtual Private Clouds (VPCs) for secure cloud connectivity.
• Knowledge of network automation, using tools like Ansible, Python, and Cisco DevNet to automate network tasks, manage configurations, and improve network efficiency.
• Skills in deploying SDN (Software-Defined Networking) solutions, including Cisco ACI, VMware NSX, and other SDN platforms for centralized control and automation of network resources.
• Proficiency in network security best practices, including configuring network segmentation, firewall rules, VPNs, and encryption protocols to protect sensitive data and ensure network integrity.
• Experience in configuring and managing data center networks, including load balancers, Layer 2 and Layer 3 switching, and network virtualization for high availability and scalability.
• Knowledge of disaster recovery (DR) strategies, including configuring network redundancy, failover systems, and ensuring business continuity through network disaster recovery plans.

Overall, a Senior Network Engineer Assessment Test evaluates candidates' abilities to design, implement, and manage advanced network infrastructures, ensuring they can maintain secure, scalable, and high-performance networks.

It assesses both technical skills (such as routing, switching, and security) and practical expertise (such as network automation, cloud networking, and SDN), ensuring candidates can handle complex network challenges and deliver reliable networking solutions for enterprises.
