Hello,
The fast track exam is only allowed for engineers that meet the requirement of having an equivalent or higher level certification from another vendor (for example Cisco CCNP or CCIE). You will be asked to send proof of this upon applying for your certification.
If you don't meet this requirement, you will have to take the 3 regular exams to get the HCIP-R&S certification.
It looks like the exam center has taken the relevant page off the shelf. For any questions related to certification, you can send an email to the official email address certification@huawei.com .
For more detail, please check the following post:

Hope this helps!
Thanks
