Core Knowledge Questions Removed for CCIE R&S and Voice Lab Exams

Cisco removed the Core Knowledge Questions section from the CCIE R&S and Voice Lab exams.

This sections STILL exist on CCIE Service Provider, CCIE Security, CCIE Storage Networking and  CCIE Wireless Lab.

Please find below the official announcement and the reasons regarding this section removal from R&S and Voice lab exams:

With more than six months of exam results now available, Cisco is able to report that the troubleshooting components of the CCIE R&S v4.0 and CCIE Voice v3.0 lab exams are performing well in validating expert level networking skills.  Considering these results, Cisco has decided to eliminate the Core Knowledge questions from the current CCIE R&S v4.0 and CCIE Voice v3.0 Lab Exams.  Beginning on May 10, 2010, CCIE R&S and CCIE Voice Lab Exams, in all global locations, will no longer include the four open-ended Core Knowledge questions.  The total lab time will remain eight hours.  For the CCIE R&S Lab Exam, this means candidates will begin with the two-hour Troubleshooting section, followed by a six-hour Configuration section.  For CCIE Voice, candidates will have the full eight hours to complete the integrated exam.  At this time, only the R&S and Voice tracks will be eliminating the Core Knowledge questions.

CRS-1: Cisco’s huge router reaches five-year milestone

Cisco introduced the CRS-1 (Carrier Routing System) on May 25, 2004, as its first multichassis core router platform. The numbers were impressive: Fully configured, the system would have 72 racks of network interface modules and eight racks of interconnecting “fabric” modules, all acting as a single router with 92Tb per second (Tbps) of capacity. In the four-year development of the CRS-1, Cisco even created a new version of its IOS (Internetwork Operating System) software, called IOS XR. The new OS shared elements with the traditional IOS, including its venerable command-line interface, but had a modular architecture for high availability.

Five years later, Cisco’s predictions of high-definition online video and ever-growing demand for Internet capacity have come true, and big carriers including AT&T, Verizon Wireless, China Telecom, Telstra, Comcast and BT Group all have deployed CRS-1s, according to Cisco. But the rising tide has lifted rival Juniper Networks’ core routers even more than Cisco’s, and China’s Huawei Technologies is making inroads in the lower end of the market, according to one analyst.

The CRS-1 came in the wake of Juniper Networks’ T Series routers and TX Matrix interconnection system, another big multichassis platform for the core of carrier networks. It also emerged after several startups, including Caspian Networks and Procket Networks, had tried to jump into the big-money business of supplying the biggest routers on the Internet amid a historic telecommunication crash. Shortly after introducing the CRS-1, Cisco announced it was buying Procket’s assets.
