In a typical global server load balancing (GSLB) setup, how many FQDNs can a single GSLB vServer balance?

• A. Up to 2
• B. Up to 10
• C. Several FQDNs
• D. Only one FQDN

Answer: (D)

A GSLB vServer is created to handle DNS responses for a single FQDN. Its configuration, health checks, and load‑balancing policy apply to that particular hostname, directing traffic to the appropriate global resources. Because of this one‑to‑one relationship between a vServer and an FQDN, a single GSLB vServer can balance only one FQDN. If you need to balance additional FQDNs, you would set up separate GSLB vServers for those hostnames. The vServer can still distribute traffic across multiple IPs and sites behind that FQDN, but not across multiple FQDNs within the same vServer.
