The first and most obvious reason to take the CCIE Routing and Switching written exam is that it is the first step toward obtaining the CCIE Routing and Switching certification. Also, you cannot schedule a CCIE lab exam until you pass the appropriate written exam. In short, if you want all the professional benefits of a CCIE Routing and Switching certification, you start by passing the written exam.
The benefits of getting a CCIE certification are varied, but here are just a few of the reasons: ■ Better pay
■ Better career advancement/new job
■ Applies to certain minimum requirements for Cisco Channel Partners, making you more valuable to Channel Partners
■ Better movement through the problem-resolution process when calling the Cisco TAC ■ Prestige

The other big reason to take the CCIE Routing and Switching written exam is that it recertifies an individual’s associate-, professional-, and expert-level Cisco certifications. In other words, passing any CCIE written exam recertifies that person’s CCNA, CCNP, CCIP, CCSP, CCDP, and so on. (Recertification requirements do change, so please verify the requirements at Cisco.com.)
The CCIE Routing and Switching Written Exam 350-001
The CCIE Routing and Switching written exam, at least as of the time of publication, consists of a 2-hour exam administered at a proctored exam facility affiliated either with Pearson VUE (http://www.VUE.com/cisco) or Thomson Prometric (http://www.2test.com). The exam typically includes approximately 100 multiple-choice questions, with no simulation questions currently on the written exam. Because the written exam is typically followed at some point by an attempt at passing the lab exam, Cisco has little motivation to add simulator questions to any of the CCIE written exams.
As with most exams of any kind, everyone wants to know what is on the exam. Cisco provides general guidance as to topics on the exam in the CCIE Routing and Switching written exam blueprint, the most recent copy of which can be accessed at http://www.cisco.com/go/ccie. Cisco changes both the written and lab blueprints over time, and with CCIE, Cisco seldom, if ever, changes the exam number. (Cisco changes the exam numbers of the associate- and professional- level certifications when it makes major changes to what is covered on those exams.) Knowing that the content will change over time, this book includes Appendix B, “CCIE Exam Updates.” This appendix will include coverage of any newly added topics to the CCIE Routing and Switching written exam. When Cisco changes the blueprint, the authors will add content to cover the new topics at http://www.ciscopress.com/title/1587201410, with that content also being available to all readers who have bought the earlier edition of the book. For future printings, Cisco Press will put that new content into Appendix B.
The CCIE Routing and Switching written exam blueprint, as of the time of publication, is as follows: I. General Networking Theory
A. OSI Models
B. General Routing Concepts C. Standards
D. Protocol Mechanics E. Commands
II. Bridging and LAN Switching A. Transparent
B. LAN Switching C. MLS
D. Data Link Layer E. Ethernet
F. Catalyst IOS Configuration Commands III. IP A. Addressing B. Services C. Applications D. Transport E. IPv6 F. Network Management IV. IP Routing A. OSPF B. BGP C. EIGRP
D. Route filtering and Policy Routing E. DDR
F. RIPv2
G. The use of ‘show’ and ‘debug’ commands V. QoS A. Traffic classification B. Congestion management C. Congestion avoidance VI. WAN A. Frame Relay B. Physical Layer C. Leased Line Protocols VII. IP Multicast A. IGMP/CGMP B. Addressing C. Distribution Trees D. PIM-SM Mechanics E. Rendezvous Points F. RPF
xxxiv VIII. Security A. Access Lists B. LAN security C. Device Security/Access D. Spoofing
IX. Enterprise Wireless Mobility A. Standards B. Hardware C. SWAN D. RF Troubleshooting E. VoWLAN F. Products
The blueprint tells you what major topics to study, and which not to study by implication. However, the blueprint does not provide many details about the scope and depth covered for each topic. For example, the blueprint lists BGP, without any details. While the lack of details on the depth and breadth of coverage may be a little frustrating, the positive perspective is that the lab can cover far more details—so it is never a bad idea to study too many details for the written exam, because the extra topics are probably topics that could be on the lab exam anyway.
Knowing what topics Cisco does not list in the blueprint is also useful, particularly topics that Cisco has removed from earlier blueprints. For example, Cisco announced the removal of ISDN/DDR, IS-IS, ATM, and SONET from the written exam blueprint during the summer if 2005, making it a reasonable strategy to simply not study those topics today. Also, there is a possibility that MPLS might be added back to the exam—check http://www.cisco.com/go/ccie for the latest information regarding MPLS or any other new or deleted blueprint topics.
