What is the purpose of the MIR option in GSLB?

• A. To return multiple IPs for the best performing service
• B. To return only one service
• C. To store DNS records
• D. To drop responses

Answer: (A)

MIR in GSLB determines how many IP addresses are returned for the chosen (best performing) site. The idea is to give clients several healthy endpoints for that site, so if one endpoint is slow or unavailable, others are still reachable, improving availability and potentially performance. The best performing service is selected based on health checks, proximity, and other performance metrics configured in the GSLB policy. Returning multiple IPs avoids a single point of failure that comes with a lone IP, and it isn’t about storing DNS records or dropping responses.
