Failed CCIE Enterprise Infrastructure? Here's Your Recovery Plan

Pro tip: Review the exam topics page on Cisco's site, they update objectives periodically.

• Preparing for the lab as though it were the old single configuration exam. A whole module of the eight hours is Design, in which you write no configuration at all.
  Split your practice the same way Cisco splits the exam. Rehearse design scenarios separately from configuration drills, and get comfortable committing to an answer you cannot revisit, since Cisco's CCIE exam product manager states you cannot go back to a previous question once you move forward in the Design module.
• Studying MPLS to service provider depth. The blueprint scopes MPLS to label stack, LSR, LSP, LDP, MPLS ping and traceroute, and L3VPN with MP-BGP VPNv4 and VPNv6.
  Stop at L3VPN. Traffic engineering, segment routing and L2VPN are not on the Enterprise Infrastructure lab blueprint. Redirect the saved hours into SD-Access and SD-WAN, which together carry 25 percent.
• Building DMVPN from scratch in practice when the blueprint asks you only to troubleshoot Phase 3 with dual hub.
  Practise fault isolation on a pre-built dual-hub Phase 3 topology. Break NHRP registration, break IKEv2 preshared keys, break the tunnel source, and drill on diagnosing each from show output rather than rebuilding.
• Not saving configurations during the eight hours. Cisco's policy states plainly that under no circumstance is it the responsibility of the lab proctor to save candidate configurations.
  Save after every completed task. Build the habit during mock labs so it survives hour six, when fatigue erodes discipline and a device reload can cost you an entire section.
• Burning half an hour troubleshooting suspected equipment failure instead of escalating. Cisco instructs candidates to spend no more than 10 minutes on a suspected equipment problem before reporting it.
  Set a ten-minute cap and stick to it. Note that proctors do not troubleshoot candidate configurations, so be sure the fault is in the environment rather than in your own work before you raise it.
• Arriving late on lab day. If you arrive more than two hours after the exam start time, Cisco will not allow you to start, and cancellation forfeits the full 1,600 USD.
  Arrive the day before, especially for a Mobile Lab site or an overseas booking. Cisco also warns that start times vary by location, and the address is in your confirmation email rather than assumed from the city.
• Booking a lab date without checking visa lead time. Cisco recommends applying at least 10 to 12 weeks before the exam date and will not assist with documentation beyond the visa invitation letter.
  Download the visa invitation letter from the Visa Invite tab in the Cisco Expert Level Certifications Tracker as soon as you book. If the visa does not arrive, the cancellation policy still applies and the payment is not refunded.
• Assuming a re-read is a cheap second opinion. It costs 1,000 USD plus tax, must be requested within 14 days, takes up to three weeks, and is limited to one per attempt.
  Request a re-read only when the tracker offers the option, since Cisco makes it available only for exams with the potential to change from Fail to Pass. The 1,000 USD is refunded only if the result actually flips.
• Ignoring the automation domain because it is only 15 percent. It carries the same weight as the entire Transport Technologies and Solutions domain, and it is graded on working output rather than on description.
  Rehearse EEM applets, guest shell Python, vManage and Catalyst Center API calls and a gRPC on-change telemetry subscription until each runs first time. The DevNet Sandbox costs nothing and mirrors the exam tooling.

• 7-10 years of networking experience recommended
• Pass ENCOR 350-401 written exam first ($450)
• Lab exam is 8 hours hands-on, practice speed
• INE and Cisco's own labs are top prep resources
• Master BGP, OSPF, MPLS, SD-WAN, and automation
• Budget 12-18 months of dedicated study
