You should know some basics about a few of the hardware platforms Cisco offers for remote access. Specifically, you need to know the information in Table 2.3 for the Cisco 800, 1600, 1700, 2500, 2600, 3600, 3700, AS5000, and 7200. Knowing how many and which interface types are available on each hardware platform will help you select the correct router for each of the different environments. Table 2.3.
