How clients handle the DNS – requests to the failed servers?..

Answer / Mayur Kumar Jaiswal

Clients typically handle requests to failed servers using various techniques such as: 1. Timeouts: If a server fails to respond within a certain time, the client retries the request or moves on to another available server. 2. Load balancers: In a load-balanced environment, requests are automatically routed to healthy servers based on their availability and load. 3. DNS failover: Some DNS systems support health checks for servers and redirect traffic away from failed servers by updating the corresponding DNS records. 4. Service discovery tools: Services like etcd or Consul help clients discover and connect to available servers in a dynamic environment.
