A Citrix Administrator configured global server load balancing (GSLB) for www.citrix.com, with two ADNS services named Citrix ADC 1 and Citrix ADC 2 in the setup.
Which record does the administrator need to add on the parent DNS server to delegate requests from www.citrix.com to Citrix ADC 1 and Citrix ADC 2?
To delegate requests from www.citrix.com to Citrix ADC 1 and Citrix ADC 2, the administrator needs to add a Name Server (NS) record on the parent DNS server. NS records are used to delegate a subdomain to a set of name servers. They specify the authoritative DNS servers for a particular domain, enabling the delegation of DNS resolution to Citrix ADC 1 and Citrix ADC 2 for the www.citrix.com domain.
