Cisco Networking Academy CCNA Exploration Lab and Study Guide books
Cisco Press publishes several books for each Cisco Networking Academy course. For CCNA, Cisco separates the course material into four semesters. Cisco also has two curricula for CCNA, one of which is called CCNA Exploration. This particular curriculum includes a lab guide for each semester. Designed to be used in class, the books can be useful for self-study as well.
