In Internet edge topology where is the best place to put NTP server so users can easily access to it?
The correct answer is B. Internal network. In an Internet edge topology, the network is typically segmented into: external DMZ (publicly accessible, facing the internet), internal/private network (trusted internal zone), and private DMZ (semi-trusted zone for internal-facing services).

Explanation
In an Internet edge topology, the network is typically segmented into: external DMZ (publicly accessible, facing the internet), internal/private network (trusted internal zone), and private DMZ (semi-trusted zone for internal-facing services). Placing the NTP server in the Internal Network (B) ensures it is directly reachable by internal users without requiring traffic to traverse DMZ boundaries or firewall rules designed for external access. The internal network has low latency, high trust, and no exposure to external threats, making it the optimal location for a service like NTP that internal users need reliable, constant access to. An External DMZ placement would expose NTP to the internet unnecessarily. A Private DMZ adds complexity without benefit for a purely internal service.
