The correct answer is Operational costs. This option is least likely to be a common problem because distributed IT architectures more often create governance, coordination and communication challenges rather than being primarily driven by uncontrollable operational cost issues.

Distributed architectures frequently use managed services, automation and elastic scaling which can make operational spending more predictable or more efficient. For that reason Operational costs are less commonly the dominant problem compared with difficulties around people and process.

Policy and oversight is incorrect because decentralization increases the need for clear governance, standards and compliance. Without consistent policy and oversight different teams can drift into divergent practices that introduce risk.

Coordinating activities across teams is incorrect because distributed systems raise dependencies and sequencing issues that require careful coordination of deployments and changes across multiple teams. Coordination overhead is a common operational pain point.

Inter-team communications is incorrect because more distributed ownership and more services create additional handoffs and context gaps. Effective communication is therefore frequently a significant challenge for organizations with distributed IT.
