Why might a DNS client choose recursive navigation rather than iterative navigation? What is the
relevance of the recursive navigation option to concurrency within a name server?
What will be an ideal response?
A DNS client may choose recursive navigation simply because it is too basic to perform iterative navigation.
A server that performs recursive navigation must await a reply from another server before replying to the
client. It is preferable for a server to deal with several outstanding client requests at one time rather than
holding off other requests until each one is completed, so that clients are not unduly held up. The server will,
in general, refer resolution to several other servers rather than just one, so client requests will be satisfied in
parallel to some extent.
