Final answer:
The provided scenario does not explicitly mention Dewgood's IT infrastructure limitations but suggests potential issues with overreliance on technology and vulnerabilities to system failure or security risks.
Step-by-step explanation:
The key limitation in Dewgood's current IT infrastructure, as described in the scenario, is not explicitly mentioned in the provided information. However, based on the provided information, we can infer that the overreliance on technology and the infrastructure's susceptibility to total system failure or security risks such as data breaches or technological malfunctions could be potential limitations.
These risks highlight the importance of reliable backups, robust security protocols, and contingency planning to safeguard against disasters or systematic attacks.
