The picture above is a lookalike of basic topology of this class.
CIERS1 and 2 is a five successive days for each class. It cost you about 1million yen(which is about $10,000).
CIERS1 has a some reviews of technology with a thick textbook so that was not a tough class, but CIERS2.
In the CIERS2, you have to take up to five respective assessments include configuration and troubleshooting. Those assessments have the highest difficulty to solve and your brain will get exhausted after finishing five days of assessments.
After eight hours of assessment, you should review what you did for the day, since those routers and switches for the class is located at cisco, USA. You do not have to review, but you should. You know what it means.
Actual topology has Cat 3560 on SW1 through SW4. GNS3 can only simulate routers so I substitute switching module to make similar topology.
Project is located at the public dropbox. Download it as you need. After download it, you should locate your own IOS in the IOS folder. You may need to rewrite the .net file, it depends on which IOS you own.
