CCNA 4 - Final Exam (A)

1. A network administrator is asked to design a system to allow simultaneous access to the Internet for 250 users. The ISP for this network can only supply five public IPs. What can be used to accomplish this task? • routable translation • dynamic translation • static translation • port address translation 2. The LAN attached to the Ethernet interface of the Raleigh router shown in the graphic is addressed with private IP addresses. If one public IP is assigned to the company, which commands could be used in a configuration that allows all devices with private IPs in this network to access the Internet? (Choose two.) • ip nat inside source list 1 interface serial0 overload • ip nat outside source list 1 interface serial0 overload • ip nat inside serial0 • ip nat inside source list 1 pool Raleigh overload • ip nat inside Raleigh overload • ip inside nat source list 1 interface serial0 Raleigh 3. The command output shown in the graphic was taken from a Cisco 806 broadband router. Which k

What value in the address field of a Frame Relay header identifies the destination of the frame? • CIR • DE • DLCI • ISDN • FRAD • PVC 3. The serial PPP link between the Left and Right routers is configured as shown in the diagram. Which configuration issue explains why the link is unable to establish a PPP session? • The IP addresses must be on different subnets. • The usernames are misconfigured. • The passwords must be different for the CHAP authentication. • The clock rate must be 56000. • The clock rate is configured on the wrong end of the link. • Interface serial 0/0 on Left must connect to interface serial 0/1 on Right. 4.
