Difficulty: Easy
Correct Answer: All of the above
Explanation:
Introduction:
Organizations rely on networks to support diverse workflows—from moving files and running transactions to interactive terminal access and messaging. This question asks whether the typical scope of data communications support is narrow or comprehensive across these areas.
Given Data / Assumptions:
Concept / Approach:
Modern enterprise networks are multi-service platforms. They enable bulk transfers (file/backup), transactional workloads (OLTP, web transactions), structured data access (databases), legacy/remote terminal sessions, and asynchronous messaging (email, voice messages). Therefore, a realistic scope encompasses all the listed categories.
Step-by-Step Solution:
Verification / Alternative check:
Enterprise reference architectures (campus/core/data center) explicitly plan for file/DB traffic, transactional systems, email, and voice/video collaboration, confirming wide scope.
Why Other Options Are Wrong:
Common Pitfalls:
Equating “data communications” with only file transfer; overlooking interactive and transactional traffic.
Final Answer:
All of the above.
