Differences Between Exchange Server 2003 Standard and Enterprise Editions

Exchange Server 2003 comes in two editions, Standard Edition and Enterprise Edition. As the 70-284 exam involves objectives that include clustering, a feature not supported by Standard Edition, candidates should try to gain experience on the Enterprise Edition software. Candidates should also be aware of the basic differences between the two editions. The differences between the Standard and the Enterprise Editions are laid out in Table 2.1.
