What is one key benefit of hybrid deployment of Exchange?

A key benefit of a hybrid deployment of Exchange is that it allows organizations to transition to the cloud while maintaining their on-premises infrastructure. This hybrid model offers flexibility and scalability, enabling businesses to gradually move their email services and workloads to the cloud without losing the control and functionality of their existing on-premises Exchange environment.

Organizations can optimize their operations and align with cloud services while still having the option to run certain workloads locally, which can be beneficial for compliance, data security, or specific operational requirements. This approach facilitates a smooth transition, minimizes disruption to users, and allows IT departments to manage resources more effectively during the migration process.

The other choices do not accurately capture the main advantages of a hybrid deployment; for instance, reducing licensing costs or providing temporary solutions for email storage does not reflect the strategic benefits of hybrid architecture. Disabling features from on-premises Exchange runs counter to the hybrid approach, which integrates both environments rather than limiting functionality.
