The section of the exam on installing SharePoint 2010 has been known to stump some candidates. Although a basic SharePoint 2010 installation is fairly straightforward, Microsoft has been known to ask questions about scripting installations and about analyzing three different types of logs (ULS logs, installation error logs, and event logs) to troubleshoot installation problems.
Although not specifically addressed within the exam objectives, some candidates have reported seeing questions related to IIS 7, DNS, the Active Directory, and SQL Server. It is worth noting that the SQL Server Reporting Services are mentioned in the exam objectives.
Another area that seems to give candidates problems is authentication providers. Most candidates are probably familiar with the more common authentication types such as NTLM, Kerberos, and forms-based authentication. However, don’t be surprised to see a question or two on Active Directory Federation.
