My moneys on it'll be the ICND (Interconnecting Cisco Network Devices) as it's a sensible starting point for someone with knowledge of networking but maybe not cisco's kit. It's a nice mixture of lessons and hands on with the kit (labs) and supposedly teaches all you need to pass the CCNA.
But a week (5 days) is a long time in training circles, all of the below are 5 day courses from most training companies;
BSCI - Building Scalable Cisco Internetworks
BCMSN - Cisco Multilayer Switched Networks
BCRAN - Building Cisco Remote Access Networks
CIT - Cisco Internetwork Troubleshooting
ARCH - Designing Cisco Network Service Architectures
SND - Securing Cisco Network Devices
SNRS - Securing Networks with Cisco Routers and Switches
SNPA - Securing Networks with PIX and ASA v4.0
As a rule the documentation you get from training companies is really good, and becomes a useful long term reference.
Just back at work this week after a week doing the SNPA course, which is good fun and I would recommend it to anyone wanting to get a handle on the Pix or ASA products, or studying towards one of the cisco security qualifications.
