Do Creative Commons licenses affect exceptions and limitations to copyright, such as fair dealing and fair use?
No, and this is one way in which CC licenses are different from some other public licenses. The laws of all jurisdictions allow some uses of copyrighted material without permission of the creator, and may include uses such as quotation, current-affairs reporting, or parody in some jurisdictions. These exceptions vary depending on the jurisdiction, though many jurisdictions adhere closely to exceptions and limitations contained in international treaties, such as the Berne Convention. Fair use and fair dealing are two exceptions to copyright that may be relevant to your use of a CC licensed work.
