Enabling MIR on a GSLB vServer affects responses by:

• A. The best global server load balancing (GSLB) service as the first record in the response, and the remaining active services as additional records
• B. The Remote GSLB service as the first record in the response and adds the remaining active services as additional records
• C. Only the best GSLB service in the response
• D. The Local GSLB service as the first record in the response and adds the remaining active services as additional records

Answer: (A)

MIR on a GSLB vServer controls how the DNS response is built when there are multiple healthy GSLB services available. When MIR is enabled, the response is constructed so that the best GSLB service appears as the first record, and the remaining active services are included as additional records. This provides a prioritized list for clients: connect to the top choice for the best performance, but still have backup options if that top choice is unavailable or slower. This behavior helps with both optimal user experience and resilience. The first record reflects the service deemed most suitable based on health, proximity, and performance metrics, while the subsequent records offer alternatives so clients can fail over quickly or distribute load if the top option changes in the future. The other options don’t fit this behavior because MIR doesn’t force only the best service to be returned, nor does it specifically select a local or remote service as the first by default. It’s about presenting a ranked set of all active services, starting with the best.
