Recertification of JNCIP-ENT

Once certified, the JNCIP-ENT certification is valid for three years. You must recertify within the active period (three years) otherwise your designation will expire and you will need to re-earn the entire certification track, including the lower-level certificates as these are the prerequisites for more advanced validations such as the JNCIP-ENT certification. Generally, you can recertify by testing or by attending relevant courses. If need be, you can view the status of your certification by using CertManager.
