1. Please provide a brief overview of your professional experience relevant to this position. Include your roles, responsibilities, and key functions, as well as how this opportunity aligns with your overall career path. 2. Please describe your methodology for designing border/perimeter routing solutions for a campus or enterprise network. The environment includes multiple routers, multiple peers, and multiple service providers, and uses BGP as the routing protocol. Explain your strategies for managing multiple upstream connections and peers, and discuss your approach to introducing new services into an existing architecture. 3. Please describe your general methodology for troubleshooting network issues. For example, a client reports intermittent slowness or packet loss between their on-campus workstation and an external internet destination. Tier 1 support has already replaced patch cables and confirmed no errors on the local switch port. How would you proceed? In addition, please describe the network test equipment and diagnostic tools you have used or would use in this type of investigation. 4. If you were in a situation where a co-worker was doing something against company policy, what would you do? 5. Please describe your experience with network configuration automation. Include your depth of experience in both vendor-provided and internally developed automation solutions. Do you have experience integrating automation workflows with change-management platforms such as ServiceNow? 6. Please describe your experience with resilient EVPN-VXLAN deployments. If applicable, discuss your experience with IS-IS underlay routing and BGP overlay routing. Please also address spine, leaf, and super spine architectures across geographically distributed campus environments. If EVPN-VXLAN is not directly applicable to your background, please describe other Layer 2 technologies you have deployed or operated, including the scale (number of switches, MAC addresses) and loop-avoidance strategies employed. 7. Please discuss your experience developing and deploying a significant new network service. Explain your design philosophy, how you break a project into phases, how you manage delivery and risk, and how you document the service throughout the project lifecycle and at completion. 8. Please describe your experience with operating systems and applications, including databases. Which built-in tools do you use for network troubleshooting? Which third-party tools do you rely on? Please also discuss the network management systems (NMS) you have used or helped develop, and describe your familiarity with scripting languages. 9. Please describe your experience with the following (or similar) equipment. Indicate the extent of your involvement and the protocols or functions in use: • Juniper MX — BGP border/perimeter routing • Gigamon — packet broker platforms • IPS/IDS solutions • Fortinet firewalls • Cisco Nexus 9000 — core, distribution, routing, and VXLAN • Brocade/Ruckus and Aruba — access switching • Aruba — wireless APs, controllers, authentication, clusters, and conductors • Ciena — WAN/DWDM transport • DSL/T1 — remote access technologies 10. Please describe your lead-level experience with the following protocols and technologies (provide examples if time permits): • 802.11 (various standards) • RADIUS / TACACS+ / 802.1X / NAC • ICMP, IP, TCP, UDP, IGMP, PIM • BGP, OSPF, IS-IS, EIGRP • Ethernet, MPLS, VPLS, VRRP, CARP, VSRP, Spanning Tree, VLANs, QoS • SIP, RTP, and associated CODECs • SNMP, RMON, sFlow, NetFlow 11.
