Course 10231B was lacking in a few areas. I won't go into deep detail, but suffice it to say you need to make sure you're well versed on operational strategy, business continuity and high availability, cross-farm service application sharing (UPS, MMS, BCS, SSS, and WAS), cross-domain trusts and multi-farm solutions, and the ports various communications occur over (WFE to App server, SQL, Service App, HTTPs, and so on). Also, the live course skipped the module on SharePoint Online since it has changed some and the instructor and/or training provider thought it would not be on the exam, but there were a couple of questions about SharePoint Online including solutions that are split, having some content on SPO and in-house/on-premise farm.
Anyhow, if you're looking to take the exam, or just increase your level of understanding of how to administer and architect SharePoint 2010, the course is worthwhile if you can use your organization's vouchers for it. However, at this point, you have to weigh whether to pursue 2010 certifications, or wait until SharePoint 2013 is officially released and exams for it become available. In either case, happy learning and good luck on your exams.
