What are two benefits of using a single OSPF area network design? (Choose two.)

A single area can actually be more CPU intensive because all routers must maintain the complete LSDB for the entire network with no summarization boundaries; multi-area design reduces per-router SPF scope.

In a multi-area OSPF design, ABRs generate Type 3 Summary LSAs and Type 4/5 LSAs for external routes between areas. With a single area, no inter-area summarization or external LSA forwarding between areas occurs, reducing LSA types to only Type 1 and Type 2 within the single area.

Virtual links are a workaround required when a non-backbone area cannot directly connect to area 0 in a multi-area design. A single-area design has only area 0, so every router is already in the backbone and virtual links are never needed.

LSA response times are not inherently faster in a single area; in fact, a larger single area may increase SPF computation time due to a larger topology database.

The number of OSPF neighbor adjacencies is determined by network topology and interface types (broadcast vs. point-to-point), not by the number of areas used.
