• BFalse

• B

Explanation

Option B is correct because the statement contains a factual error about key management: EVS (Elastic Volume Service) encryption keys are NOT managed by Huawei Cloud itself. Instead, keys are managed by the user through Huawei Cloud's Key Management Service (KMS), meaning the customer retains control over their own Customer Master Keys (CMKs). While it is true that EVS supports strong encryption and that the process can be transparent to applications, attributing key ownership to Huawei Cloud misrepresents the security model. Option A is wrong because accepting the full statement as true would mean accepting that Huawei Cloud holds custody of user encryption keys, which contradicts the customer-controlled key management design of KMS.

Memory tip: Whenever a cloud encryption question claims the provider manages the keys, treat it as a red flag. In modern cloud security, key management is kept with the customer via a dedicated KMS - "your data, your keys" is the governing principle, not "provider holds the keys."
