In short an interesting title, exclusively written for the Cisco Network Academy students, who are preparing for the Cisco CCNA 640-802 Certification exam. The author Allan Johnson takes a very broad look at practical way to make you understand the concepts in 31 days in a very concise way. He has emphasized on concepts and terminologies used in Cisco CCNA 640-802 Certification exam in an interesting way which definitely helps you to summarize your learning.
Although the title "31 days before your CCNA Exam" aims at Cisco Network Academy students, but it can be used for the Cisco CCNA 640-802 Certification aspirers who does self study.
The author Allan Johnson divided the title suiting in to 31 chapters, which are so concise you can finish each chapter in an hour. The cream of the title "31 days before your CCNA Exam" is the section called "Exam day and post exam information" which gives the CCNA Certification aspirers guidelines on what to expect after the completion of exam as well as what they should do if they fail to pass the exam on first attempt. One more section that I really liked is "CCNA Skills review and practice" which helps you to practice the CCNA skills which includes most of the CCNA 640-802 exam configurations skills in one topology, which covers topics like VLAN configuration, frame-relay configuration, inter vlan routing, EIGRP,VTP, port security , STP. You can practice those topologies either on Cisco Packet Tracer or GNS3 graphical network simulator.
Overall the title "31 days before your CCNA Exam" is a true gem, but cannot be a only source for passing CCNA 640-802 exam, this title is good for the some one who is looking for quick reference on CCNA 640-802 exam topics in an well organized way. I thank Cisco Press and Jamie in particular for providing me the copy of "31 days before your CCNA Exam"
