ITIL Foundation certificate

Answer:
ITIL Foundation certificate can be achieved by passing certification exam. For Foundation level classroom training is not necessary. That means that you can make certification exam trough web proctoring. However, in that case you must study whole material by yourselves. However, classroom training provides faster learning track and includes (almost always) certification exam opportunity. Also, there are plenty online trainings and some of them include or provide certification exam.
Since 01.01.2018 Peoplecert is the only exam provider, so please check there for web-proctored exam or training providers.
