Mongodb Ismaster Topology Await Admin

Client issues a MongoDB ismaster / hello handshake command targeting the admin database while including topologyVersion tracking fields and maxAwaitTimeMS, indicating use of modern streaming topology monitoring semantics. The request is used to determine server role, replica-set state, and topology change notifications within the administrative namespace. This primitive reflects advanced deployment reconnaissance and cluster-state discovery activity typically performed by automated drivers, monitoring tooling, or pre-exploitation scanning frameworks validating MongoDB exposure and configuration.
