What does MIR do in GSLB?

• A. It always returns all services
• B. It randomizes the order
• C. It returns only the best service
• D. It returns the best GSLB service as the first record and adds remaining as extra records

Answer: (D)

MIR in GSLB focuses on delivering a prioritized DNS response. It sends the best GSLB service as the first record and includes the remaining services as extra records. This means the client will typically connect to the most suitable site first, while still having other options available if the primary one isn’t reachable or is slower. The “best” service is determined by the GSLB logic (health, proximity, latency, load, and configured weights). By placing that optimal option upfront, MIR helps improve performance and reliability without discarding other sites. It isn’t about always returning every service in a random order, and it isn’t about returning only one service; it’s about giving the best first, followed by the others as backups.
