What statement describes the behavior of a GSLB response when multiple active services are available and MIR is enabled?

• A. It returns only one service
• B. It returns multiple active services, with the primary first
• C. It returns a random subset of services
• D. It disables Local GSLB and uses only remote services

Answer: (B)

With MIR enabled, when several services are healthy, the GSLB DNS response returns all active endpoints in a prioritized list, placing the designated primary service first. This means clients receive multiple options, attempt the primary first, and automatically fall back to the next active endpoints if the primary is unavailable or slow. It provides deterministic ordering for the preferred site while still offering redundancy across the other active services.
