Question: In a 3GPP IP-based service network, what is the primary goal of hiding network topology from other operators, as related to S-CSCFs (Serving-Call Session Control Functions)?
Option 1: To conceal the number and capabilities of S-CSCFs for competitive advantage.
Option 2: To enhance the security of user data transmission between networks.
Option 3: To facilitate easier interoperability with other operators' networks.
Option 4: To reduce the computational load on I-CSCF/IBCF (Interrogating-Call Session Control Function/Interworking Border Control Function).
Explanation: Hiding network topology, including details about S-CSCFs, is crucial for operators to protect sensitive business information from competitors. This is directly related to maintaining a competitive advantage by not disclosing the operational capabilities and structure of their network.
