Remote Access
The CCDP exam requires you to have an in-depth understanding of remote access
technology. Remote access is essential to any network today, when there are more ways to
access a network than ever before. The CCDP candidate must constantly keep up with new
technology in this area but stay familiar with older technologies as well.
This chapter discusses older technologies, including ISDN. Newer technologies such as
cable and DSL will be briefly mentioned, and some of the Cisco features used with ISDN,
including IP unnumbered, will be discussed.
