Homework Help: Questions and Answers: Which router service enables remote administration of the router through a modem or auxiliary port?
A. DHCP
B. PAD
C. CDP
D. BOOTP
Answer:
First, let’s understand the question: We need to identify a service that enables remote router administration, specifically through a modem or auxiliary port.
Given Options: Step by Step Answering
a) DHCP (Dynamic Host Configuration Protocol)
- This protocol is used to dynamically assign IP addresses to devices on a network. It does not involve remote administration of routers through modem or auxiliary ports.
b) PAD (Packet Assembler/Disassembler)
- PAD is used for enabling remote administration of network devices. It allows for remote terminal access to the router through auxiliary or modem ports, which is commonly used in remote network management.
c) CDP (Cisco Discovery Protocol)
- This is a Cisco proprietary protocol used to share information about directly connected Cisco devices. It does not provide remote administration capabilities.
d) BOOTP (Bootstrap Protocol)
- This is a network protocol used for obtaining an IP address from a server during the boot process. It is similar to DHCP but does not have the functionality for remote router administration.
Final Answer
Based on the above analysis, the correct answer is:
b) PAD (Packet Assembler/Disassembler)
This option is correct because it provides the capability for remote terminal access via a modem or auxiliary port, which is a common setup for managing routers in remote locations.
