Describe a shortcoming of using DNS for load balancing of Web servers.
What will be an ideal response?
A shortcoming of using DNS for load balancing is that it relies on multiple Web servers, each with its own IP address. Then, because Web clients save recently resolved addresses, the next time a client wants to access the same (Web) server, it will check its cache, skipping the DNS and the round robin.
