Perform a course?

Answer:
From my point of view, if you want to have warranties to pass the exams, will be better if you perform a course. Anyway, I don’t know your real knowledge about ISO 27001, but with the resources that you have and your experience could be enough (although my recommendation is a course)

Regarding the questions of the exam, I am sorry but we do not have this specific information, although this free webinar can help you for the preparation of the Lead Auditor exam “ISO 27001 Lead Auditor Course preparation training” : https://advis era.com/27001academy/webinar/iso-27001iso-22301-the-certification-process-free-webinar/01-lead-auditor-course-preparation-training-free-webinar/
