Which of the following BYOD deployment options uses an open SSID for provisioning employee devices and a secure SSID for already provisioned employee device access?

The correct choice is based on the dual SSID deployment model, which effectively separates the provisioning phase from the secure network access phase for employee devices. In this model, an open SSID is provided specifically for the initial setup and provisioning of Bring Your Own Device (BYOD) employee devices. This allows devices to connect easily without requiring credentials, facilitating a smooth onboarding process.

Once the provisioning is complete, employees' devices transition to a secure SSID, which enforces authentication and encryption to protect the data on the network. The secure SSID ensures that only authenticated and compliant devices can access sensitive resources, enhancing overall network security while maintaining user convenience during the provisioning process.

In contrast, the other options do not align with this particular deployment strategy. The guest SSID deployment typically serves visitors and provides limited access, while the single SSID deployment often does not differentiate between provisioned and unprovisioned devices. Open SSID deployment refers to a less secure method without restriction and does not involve a secure network for authenticated users. Thus, the dual SSID deployment model uniquely addresses the requirement for both provisioning and secure access effectively.
