Question: When designing DCN (Data Communication Network) architectures for telecommunication management, what is the primary consideration for selecting communications channels (e.g., dedicated lines, circuit-switched networks, packet networks)?
Option 1: Maximizing network security through encryption
Option 2: Balancing availability and network delay while minimizing cost
Option 3: Ensuring compatibility with legacy system protocols
Option 4: Prioritizing the use of open-source technology for flexibility
Explanation: In telecommunication management, DCN architectures must be carefully planned to ensure they meet performance and financial objectives. The correct answer reflects this by highlighting the importance of balancing two critical network performance metrics (availability and delay) with operational expenditure (cost), which is a key consideration in telecommunications infrastructure planning.
