please i want a help to understand that statement:

Access node’s DNS record should have CNAME entries equal to the number of protected
websites’ domain names. The entry format should have the access-node ID as a sub-domain
for each protected website domain name, i.e., “ANnumber.domainP.com”, this is to guarantee
compatibility with SSL, where wildcard certificates must be used by the protected web
servers. Access-node health information must be sent to the trusted public servers
periodically, or on the event of an abnormal event (i.e., access-node under sudden attack).

please for any help i am very thanks
regards
sarah
