What NetSim Is Reported to Provide for ENCOR Practice
The strongest case for NetSim is its hands-on format.
This role is useful, but it has a defined scope. The practical value here is the value of a starting point: a way to work with a virtual lab while preparing for CCNP ENCOR. It does not, by itself, establish that every lab area needed for your preparation is available. A lab can be useful for retaining skills while still requiring supplementation for particular technologies, configuration patterns, or practice methods.
The reported assessment makes that distinction directly. NetSim is described as a good start for practical CCNP ENCOR study, while another lab resource is still considered necessary to pass the exam. The same assessment also says that, when it comes to practical CCNP ENCOR preparation, NetSim is not enough. Those statements define a sensible way to use the product: treat its hands-on exercises as one stage of preparation, not as proof that no additional lab work is needed.
Before relying on it as your only practice environment, identify the tasks you expect to rehearse. If those tasks fit the available hands-on experience, NetSim may provide useful practice for that portion of your plan. If your plan depends on technologies or workflows outside that experience, the starting-point benefit does not remove the need to cover them elsewhere. The relevant question is not whether the virtual lab has value; it is whether that value covers the work you actually intend to perform.

Check Whether the Reported Missing Lab Areas Matter to Your Practice Plan
The reported omissions are specific enough to evaluate individually. They include GRE and IPSEC tunnel labs, QoS coverage beyond CoPP, BGP work beyond the very basics, and an automation lab focused on NETCONF or RESTCONF. Each omission represents a different kind of practice question, so a single overall label such as “complete” or “incomplete” is less useful than checking the areas one by one.
Start with tunnel practice. No GRE/IPSEC tunnel labs are reported. If your preparation plan requires hands-on work with either of those tunnel types, that practice is not supplied by the identified coverage. The appropriate response is to mark tunnel configuration and troubleshooting as a supplementation item rather than assume that general virtual-lab access covers it.
QoS requires a separate check. The reported QoS coverage does not extend beyond CoPP. That means CoPP is identified, but broader QoS practice is not represented in the reported coverage. If your plan includes QoS tasks outside CoPP, check those tasks explicitly and arrange additional practice for the parts that are not covered.
The same distinction applies to BGP. The reported BGP coverage is limited to the very basics, with no route maps or prefix lists identified. Basic BGP practice and policy-oriented BGP work are therefore different checks. If route maps or prefix lists are part of the work you need to perform, they should be treated as an uncovered practice requirement rather than inferred from the presence of basic BGP material.
Automation is another independent decision point. The automation section is described as benefiting heavily from a NETCONF/RESTCONF lab. That is a specific indication that the reported automation practice does not fully address the need identified for those interfaces. If your plan includes this kind of automation work, add it to the list of areas requiring further lab coverage.
This approach keeps the supplementation decision tied to actual practice requirements. Compare your intended work with the four reported areas: GRE/IPSEC tunnels, QoS beyond CoPP, BGP route maps and prefix lists, and NETCONF/RESTCONF automation. Any area that is necessary to your plan but absent from the reported coverage remains an open lab requirement. The omissions do not need to determine every learner’s preparation, but they do matter wherever the omitted task is part of the work you need to practice.
Factor Reported Workflow Limits Into Your Lab Choice
Technology coverage is only one part of a lab environment. The way you build, run, read, and recover from lab work also affects whether the environment fits your practice plan. Several reported limitations concern those workflow steps rather than a particular ENCOR technology.
Custom-topology testing is the first distinction to make. The designer does not let you run your topology to test custom labs, a limitation described as disappointing. Following prepared lab work and testing a topology of your own are therefore separate needs. If your plan is based on completing existing exercises, this limitation concerns a capability you may not require every day. If your plan depends on creating and running custom labs, the limitation is directly relevant and should be accounted for before treating the environment as your only practice option.
Recoverability is another consideration. Frequent bugs were reported, especially console environments freezing and requiring the lab to be restarted from the beginning. A restart requirement changes the practical cost of an interruption: work may need to be repeated rather than simply resumed. The experience here is an individual report, not a claim that the same behavior occurs for every user or environment. It is still a relevant workflow question for anyone whose study plan depends on uninterrupted practice sessions.
Visibility can also affect how efficiently you work. The lab information is online, but reading it while both the information and the lab are loaded on a single screen was reported as very difficult. In addition, a port-label view was reported as unavailable while running a topology. These are different visibility concerns: one involves reading instructions alongside the lab, while the other involves identifying ports during topology work.
Evaluate these limitations against your own method. Ask whether you need to run custom topologies, whether repeating a lab after a freeze would disrupt your sessions, whether you normally work from one screen, and whether port labels are important during topology exercises. A limitation matters most when it conflicts with a requirement of your practice routine. This check prevents a coverage decision from overlooking the mechanics of using the lab day to day.
The result may be a need for supplementation even when a particular technology is present. Additional practice may be necessary because of a missing lab area, or because the available workflow does not support the way you need to build and test. Those are separate reasons, and both should be considered before relying on one environment for all practical preparation.
Plan for Supplementary Labs While Evaluating the Update
The reported conclusion is direct: NetSim is described as a good start for practical CCNP ENCOR study, but another lab resource is needed. That recommendation should shape the preparation plan now. Use the available hands-on practice where it fits, identify the omitted areas that matter to your work, and arrange supplementary lab practice for those areas rather than waiting for one environment to become sufficient by assumption.
The planned update is relevant, but it is a future condition rather than a completed solution. Work is described as underway on an update to NetSim for 350-401 ENCOR. The update will include additional labs intended to cover the gaps that were mentioned. This response acknowledges the specific needs around the current coverage, but it does not establish that the update has already been released or that it resolves every gap.
The subscription condition is also specific. Once available, the update is stated to be free and to run concurrently with an existing NetSim subscription. That gives current subscribers a condition to verify when the update becomes available. It does not establish any unstated eligibility condition, guarantee that a subscription will remain active, or replace the need to evaluate whether the added labs match the tasks in your own preparation plan.
A practical plan can therefore use three stages. First, use NetSim for the hands-on practice it provides and for retaining those skills. Second, list the reported gaps that matter to you: GRE/IPSEC tunnels, QoS beyond CoPP, BGP route maps or prefix lists, and NETCONF/RESTCONF automation. Third, use another lab resource for the required gaps while monitoring the ENCOR update.
When the update is available, compare its additional labs with that same list instead of accepting the update as a general completeness claim. Check whether the relevant tunnel, QoS, BGP-policy, and automation work is actually present for your needs. Also reconsider the workflow requirements identified above, including custom-topology testing, console recovery, single-screen readability, and port identification. New content may affect coverage, but the reported update statement does not by itself resolve the separate workflow limitations.
The clearest decision is consequently conditional. NetSim can be included as a useful hands-on component for practical ENCOR study, but the reported gaps support planning for another lab resource. The update may change that assessment for some practice needs once it is available and evaluated, while the present preparation decision should continue to account for the missing areas and the reported working constraints. This treats the product as a starting point without turning that starting point into a claim of complete preparation.
