ServiceNow Certified Implementation Specialist Security Incident Response certification exam is liked by me because of following reasons:
1. Because the questions are simulated and covers all the topics in the CIS-SIR syllabus
2. The performance record and result history is personalized and always available online
3. The unlimited access feature gives me peace of mind with no fear of subscription getting over
4. I can attempt the same set of questions repeatedly based on the feature of the unlimited attempts.
