RCDD · Question #49
When designing a connection to an outlying building you decide to choose a physical ring. Your primary reason for considering a physical ring is:
The correct answer is E. The physical ring provides a redundant cable path for disaster recovery. A physical ring topology is chosen primarily because it creates two independent cable paths between buildings, ensuring network availability if one path fails.

Why each option
A physical ring topology is chosen primarily because it creates two independent cable paths between buildings, ensuring network availability if one path fails.
Existing pathway access is a practical installation convenience, not a technical justification specific to ring topology.
A physical ring is more complex to install than a simple point-to-point run, so ease of installation is not a valid reason to choose it.
Campus suitability is too vague a reason and does not identify any technical advantage that a ring topology specifically provides.
A physical ring requires more cable than a direct point-to-point run, making it generally less cost-effective rather than more.
A physical ring runs cable in a loop so that two separate physical paths exist between endpoints. If one segment is cut or damaged, traffic can be rerouted through the alternate path, providing redundancy and supporting disaster recovery objectives.
