Explanation
B is correct because writing CDRs (Call Detail Records) to a database is not a responsibility of the CDR Server itself - that function belongs to a separate component, typically a billing system, mediation layer, or dedicated database writer module. The CDR Server's actual role is to collect, process, and forward/distribute CDRs to downstream systems.
Why A is wrong: While it may seem logical that a "CDR Server" would handle all CDR-related tasks including database writes, this confuses the server's collection/routing role with the persistence layer's responsibility. In telecom architectures, these concerns are deliberately separated to allow scalability and flexibility.
Memory tip: Think of the CDR Server as a post office - it receives, sorts, and routes packages (CDRs), but it doesn't store them long-term. The warehouse (database/billing system) is a separate entity that does the actual storing. The server routes; another system writes.
