About this exam

The NCoE Selection Test is a skills-based screening exam used to identify engineers ready to work in a Network Center of Excellence environment. It is aimed at network professionals who already hold foundational certification-level knowledge and now need to demonstrate operational judgement: reading a topology, choosing a path, hardening access, and diagnosing faults under time pressure. The exam is delivered in English and mixes multiple choice, multiple response, short answer, and practical scenario items. Content is organised around seven domains: network fundamentals and protocols; routing and switching; security and access control; network services and infrastructure such as DNS, DHCP, load balancing, and WAN; monitoring, troubleshooting, and performance analysis; automation, scripting, and configuration management; and documentation, change management, and operational best practices. Preparation should be lab-led rather than reading-led. Build a small virtual topology, break it deliberately, and practise explaining your diagnosis in writing, because short-answer items reward structured reasoning. Be fluent in reading packet captures, routing tables, and device logs, and be able to sketch a change plan with rollback steps. Question count, time limit, and pass mark are set by the administering body; check its official site for current figures.

What you'll study

Common questions

About NCoE Selection Test preparation

What is the NCoE Selection Test actually measuring?

It measures readiness for operational network work rather than recall of trivia. Expect items that ask you to interpret evidence, such as a routing table or capture, and justify a decision. Strong candidates explain why an option is wrong, not just why one is right.

What question formats appear?

The published format list includes multiple choice, multiple response, short answer, and practical scenario-based items. Multiple response items usually require every correct option with no partial credit, so read the stem carefully and count the selections before submitting.

How long is the exam and how many questions are there?

Those figures are set by the administering body and change between sittings, so they are not stated here. Check the official NCoE programme site or your invitation letter for the current question count, duration, and any section timing rules before you plan your pacing.

What score do I need to pass, and can I retake it?

Passing scores and retake rules are published by the exam owner, not fixed here. Confirm both on the official site before registering, especially if you are booking travel, because retake waiting periods can affect scheduling.

How difficult is it compared with a baseline certification?

Most candidates find the technical depth similar to an associate-level certification but the delivery harder, because scenario and short-answer items remove process-of-elimination shortcuts. The difficulty comes from synthesis across domains, not from obscure protocol minutiae.

In what order should I study the domains?

Start with fundamentals and routing/switching, since security, services, and troubleshooting items assume that base. Add automation once you are comfortable with device configuration. Leave documentation and change management for last, but do not skip them, as they are easy marks.

Where do candidates lose the most points?

Three patterns dominate: jumping to a fix without stating the evidence, ignoring the second fault in a multi-symptom scenario, and writing short answers as fragments. Practise answering in full sentences that name the layer, the evidence, and the next diagnostic step.

How should I prepare for the troubleshooting domain?

Build a lab with at least three routers and a couple of switches, then inject faults one at a time: wrong mask, asymmetric route, blocked DNS, duplicate address. Time yourself finding each fault and write a short incident note afterwards. That mirrors the scenario items closely.

Is automation knowledge really required?

Yes, at a working level. Expect questions on configuration management concepts, idempotency, version control for device configs, and reading simple scripts. You do not need to be a developer, but you should be able to explain what a script does and spot a risky change.

What should I bring on the day?

Follow the administering body's candidate instructions exactly, as identification and permitted-materials rules are set by them. In general, arrive early, read the scenario stem twice before answering, and reserve the final minutes for unanswered short-answer items rather than rechecking multiple choice.
