Q1Domain Verified
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?
CNAME records
SRV records
TXT records
AAAA records
Q2Domain Verified
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?
Optimization of end-user experience by directing users to the geographically closest and lowest-latency healthy endpoint.
Simplicity of implementation and minimal operational overhead.
Guaranteed distribution of traffic across all available endpoints, regardless of user location.
Enhanced security by obfuscating the true IP addresses of backend servers.
Q3Domain Verified
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?
Users will receive DNS resolution errors until the DNS cache for the primary data center's IP address expires.
Users will be seamlessly redirected to the next available healthy data center with minimal disruption.
The DNS load balancer will automatically trigger a failover to a secondary IP address without any user-side impact.
Users will experience prolonged connection timeouts as DNS caches expire slowly.
