TCP Load Distribution
NAT can be used for TCP load distribution. This works in a form that is somewhat reversed from other translations. In the other three uses of NAT, the sender uses a nonlegitimate source address in a packet destined for the outside world. In contrast, load distribution takes advantage of the NAT function by allowing a site to advertise an address but when you send a packet to the advertised address, it is rerouted to another set of addresses. Load distribution occurs, for example, when a large...

Scenario 2 You Do Not Have a CCNA Certification
Why don't you have the certification The prerequisite for the CCNP certification is to be certified as a CCNA, so you really should pursue your CCNA certification before tackling the CCNP certification. Beginning with the Remote Access exam gives you a skewed view of what is needed for the Cisco Professional certification track. That being said, if you must pursue the certifications out of order, follow the spirit of the book. Read each chapter and then do the quiz at the front of the chapter...
Assembling and Cabling the WAN Components
The CCNP Remote Access Exam requires you to have an in-depth understanding of various WAN technologies. This chapter focuses on the cabling requirements of various technologies. Although individual WAN topologies can require specific cabling variances and Frame Relay implementations require little or no variance from implementations of High-Level Data Link Control (HDLC), the physical cabling is virtually identical. However, other technologies can have different requirements depending on the...
