Tunneling offers several advantages, particularly in the context of virtual private networks (VPNs). While many choices present legitimate benefits associated with tunneling, one of the most notable advantages is its ability to provide a more cost-effective solution compared to alternative methods such as MPLS (Multiprotocol Label Switching) or point-to-point (P2P) connections.

By encapsulating packets within a secure tunnel, organizations can leverage existing infrastructure, such as the public internet, to connect remote users or sites without needing dedicated links. This reduces overall costs because organizations do not have to invest in expensive leased lines or specialized equipment to establish secure connections. The use of tunneling protocols allows for flexibility in network design and can lead to significant savings without compromising the quality of the data transfer.

The other options present benefits that might be associated with tunneling, but they are not uniquely or primarily tied to the concept of tunneling itself. For instance, while increased security is an essential feature of VPNs utilizing tunneling protocols, it is not solely a benefit of tunneling but rather a defining characteristic of secure remote access technologies overall. Similarly, avoidance of network congestion is more about network management practices than the tunneling itself, and guaranteed data delivery is typically not a feature
