Which deployment option is designed so Cisco cannot decrypt customer data?

• A. End-to-end Encrypted Deployment
• B. Hybrid Data Security
• C. Private Key Encapsulation
• D. Secure Cloud Isolation

Answer: (B)

The essential idea here is who controls the keys that unlock your data. Hybrid Data Security is built so the encryption keys are owned and managed by the customer, not Cisco. Data stays encrypted in transit and at rest, and Cisco only ever handles ciphertext; without the customer’s keys, they cannot decrypt the plaintext. This arrangement gives true protection against the service provider accessing your content, which is why it’s the best fit for a deployment designed so Cisco cannot decrypt customer data. End-to-end encryption sounds like it would achieve the same, but in practice some cloud services need to process data inside the provider’s environment to offer features like search or indexing, which can involve decrypting or handling plaintext at some stage. Private Key Encapsulation is a cryptographic technique rather than a deployment model for this guarantee, and Secure Cloud Isolation focuses on separating workloads rather than ensuring the provider cannot decrypt data if keys are accessible.
