B) The DNS service is used to translate host names to IP addresses via forward lookups and translate IP addresses to host names via reverse lookups. DNS is architected as a hierarchy of worldwide domain servers. Local DNS servers provide name resolution and possibly host names for local clients. These local DNS servers connect to DNS servers higher in the DNS hierarchy to resolve both unknown host names and host local domain names.
C) Any account password reset process won't change any keychain passwords. Therefore, the user's keychains won't automatically open when the user logs in with her new password. The user will have to manually change her keychain passwords using the Keychain Access utility.

home folder at ~/Library/Mail/V2/MailData/Envelope Index. Spotlight plug-ins can be
located in any ofthe Library folders in a folder named Spotlight.
