Q. Discuss the advantages as well as disadvantages of caching name translations for computers located in remote domains.
Answer: There is a performance benefit to caching name translations for computers located in remote domains: repeated resolution of the similar name from different computers located in the local domain could be performed locally without requiring a remote name lookup operation. The drawback is that there could be inconsistencies in the name translations when updates are made in the mapping of names to IP addresses. These reliability problems could be solved by invalidating translations which would need state to be managed regarding which computers are caching a certain translation and as well would require a number of invalidation messages or by using leases whereby the caching entity invalidates a translation after a certain period of time.
The latter approach needs less state and no invalidation messages but might suffer from temporary inconsistencies.
