When tunneling data through multiple branch sites, one primary limitation is the strain it places on data center resources. This strain occurs because tunneling, especially with protocols such as GRE or IPsec, requires additional processing power and bandwidth from the central data center to manage the encapsulation, de-encapsulation, and encryption processes involved in sending data through tunnels. As more branches connect and transmit traffic simultaneously, the demand on the data center's resources can escalate significantly. This can lead to bottlenecks, reduced performance, and increased latency, impacting the overall efficiency of the network.

In contrast, enhanced data security, improved bandwidth utilization, and reduced latency are typically advantages or goals associated with proper tunneling implementations, rather than limitations. Enhanced security comes from encapsulating and encrypting the data, improved bandwidth utilization can occur with proper traffic management, and reduced latency is often sought through direct connections. However, the overhead introduced by the tunneling process itself can compromise these potential benefits if the data center cannot handle the increased load effectively.
