質問 # 513
(What is the main function of a dynamic routing protocol?)
- A. Generate a routing table.
- B. Manage routers.
- C. Generate an IP address.
- D. Control the status of router interfaces.
正解：A
解説：
* Dynamic Routing Protocol Purpose:A dynamic routing protocol's primary function is to dynamically generate and maintain routing tables by learning and sharing routing information between routers in real time. This ensures efficient path selection and adaptation to network changes.
* Analysis of Options:
* Option A: "Generate an IP address" is unrelated to routing protocols; IP address assignment is handled by DHCP or manual configuration.
* Option B: "Manage routers" is inaccurate, as dynamic routing protocols do not manage router hardware or administrative tasks.
* Option C: "Generate a routing table" is correct because routing protocols dynamically compute and update routing tables based on network topology changes.
* Option D: "Control the status of router interfaces" refers to interface management, which is not a function of dynamic routing protocols.
* Correct answer:The main function of a dynamic routing protocol is C (Generate a routing table).

質問 # 516
On the network shown in the figure, the router receives a data packet with the destination IP address 11.0.12.1 from Host A.
After the packet is forwarded by the router, which of the following are the destination MAC address and destination IP address of the data packet?
- A. MAC-B, 11.0.12.1
- B. MAC-C, 11.0.12.1
- C. MAC-D, 10.0.12.2
- D. MAC-D, 11.0.12.1
正解：A
解説：
Comprehensive Explanation: When Router A forwards the packet to Router B, the destination IP address (11.0.12.1) remains unchanged as it is still meant for Host B. However, the destination MAC address changes to MAC-B, which belongs to Host B, since MAC addresses are only used for local network hops
