Encrypting data at rest ensures that the data stored on the SAN is protected from unauthorized access, even if the storage medium is compromised or stolen. This is a critical step to secure sensitive information and mitigate the risk of data breaches.
To ensure data on the SAN (Storage Area Network) is not compromised if it is leaked, the server administrator should:
B. Encrypt the data at rest
Encrypting the data at rest ensures that even if the data is accessed or leaked, it remains unreadable without the appropriate decryption key. This provides a layer of security against unauthorized access to the data stored on the SAN.

B. To ensure data on the SAN is not compromised if it is leaked, a server administrator should encrypt the data at rest. This means that the data is encrypted while it is stored on the SAN. This way, even if the data is accessed or copied without authorization, it will be unreadable without the encryption key.
Encrypting the data that is leaving the SAN or encrypting all network traffic can help protect data while it is in transit, but it does not necessarily protect the data if it is leaked from the SAN. Encrypting the host servers may also be a good security practice, but it does not directly address the issue of data leakage from the SAN.
I concur with answer B. I see answer D achieving the need for SAN traffic being encrypted. Why have A and D as D would take care of said traffic? The encryption of data at rest is what we are looking for.
Best Guess is A, Encrypt all data leaving the SAN. Data can leave through local transfer (USB drive) a network vulnerability from outsider/insider, . So data needs to be encrypted at rest, but also possibly in transit. But if you can encrypt "all data that leaves SAN" then that would cover everything... all these questions seem very ambiguous......
SAN is a network, the whole idea of this approach is for multiple devices to be able to access a shared filesystem, not DAS,, which is the Storage device attached to a server that SAN can use to share a filesystem across multiple devices on the network
Data Loss(breach) Prevention Method:
1; Encrypt all "SAN" network traffic..
2; Another approach is to Encrypt Data at Rest on the Storage Array of drives.
They both go together like peanut butter and jelly for a perfect sandwich (Data Breach Protection on SAN).
