Question 57
A SaaS company's new service currently is being provided through four servers. The company's end users are having connection issues, which is affecting about 25% of the connections. Which of the following is most likely the root cause of this issue?
Correct Answer: A
Comprehensive and Detailed Explanation From Exact Extract: Round-robin DNS is a simplistic form of load balancing that does not perform health checks. If one of the four servers is down, DNS will still resolve its IP to 25% of users, resulting in failed connections. This matches the symptom of 25% failure rate - 1 out of 4. Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide - under "Load Balancing Techniques and Availability": "Round-robin DNS distributes requests without regard for health status. Without external health checks, failed servers will continue to receive traffic, leading to partial service disruptions." Other options: * B. The percentages do not align with a 25% failure rate. * C. Least-connection algorithms usually have integrated health checks. * D. If health checks are active, the load balancer would not forward requests to a failed server.
