Can you solve these mystery puzzles?
In the context of global DNS load balancing for highly available applications, which of the following DNS record types is LEAST suitable for implementing sophisticated health checking and failover mechanisms directly within the DNS resolution process?
When designing a global DNS load balancing solution for an application with geographically diverse user bases and varying latency sensitivities, what is the primary advantage of employing a "latency-based routing" strategy over "round-robin" or "weighted round-robin" for the initial resolution?
Consider a scenario where a global application relies on a DNS load balancer to direct traffic to multiple data centers. If a primary data center experiences a complete outage, and the DNS load balancer is configured with a low TTL (Time To Live) for its A records, what is the most immediate and significant consequence for end-users attempting to access the application?
