Which statement describes a limitation of a typical GSLB setup?

• A. Apply spillover policies on a subset of GSLB services, and the user CANNOT have a backup for a subset of GSLB services.
• B. An administrator CANNOT define a backup for a backup Vserver in an active standby GSLB setup for a given GSLB domain.
• C. Restrict the selection of a GSLB service from a subset of GSLB service bound to a GSLB vServer for the given domain.
• D. Any given GSLB Vserver can load-balance only one FQDN.

Answer: (C)

In a typical GSLB setup, a GSLB vServer is bound to multiple GSLB services that represent different data centers or sites for a given domain. When a DNS query for that domain arrives, the GSLB engine evaluates all the bound services—taking into account health, proximity, and load—to decide which response to return. The limitation is that you cannot restrict that selection to only a subset of the bound services for the domain. The standard behavior uses the full pool of bound services to determine the response. If you need to target only a subset, you’d typically create separate GSLB domains or vServers bound to different subsets of services.
