  • You should have hands-on experience in creating guest accounts, creating and editing web login pages and self-registration pages. Apart from that, study workflows related to guest provisioning. You may do some tests on Guest services using Aruba Controller.

Summary:

After passing the written exam, you will only have 18 months to pass the ACCX Practical Exam. If you do not pass the ACCX Practical Exam within 18 months then you will have to retake the current ACCX Written Exam. ACCX practical exam (HPE0-A127P) is an eight-hour exam that tests skills on many aspects that are common to enterprise network deployments and focuses on configuration elements related to Clearpass products used in larger enterprise environments.
