What is the meaning of the term dynamic as displayed in the output of the show frame-relay map command shown? Inverse ARP is a technique by which dynamic mappings are constructed in a network, allowing a device such as a router to locate the logical network address and associate it with a permanent virtual circuit PVC.
Question 7 Which of the following describes the roles of devices in a WAN? Choose three. A modem modulates outgoing digital signals from a computer or other digital device to analog signals for a conventional copper twisted pair telephone line and demodulates the incoming analog signal and converts it to a digital signal for the digital device.
Therefore a modem terminates an analog local loop is correct. Question 8 How should a router that is being used in a Frame Relay network be configured to avoid split horizon issues from preventing routing updates?
A: Configure a separate sub-interface for each PVC with a unique DLCI and subnet assigned to the sub-interface B: Configure each Frame Relay circuit as a point-to-point line to support multicast and broadcast traffic C: Configure many sub-interfaces on the same subnet D: Configure a single sub-interface to establish multiple PVC connections to multiple remote router interfaces Correct Answer: A Explanation Look at the figure below: In the figure, router R1 has two point-to-point subinterfaces.
The s0. Each subinterface is on a different subnet. A: VLAN support.
