Encryption Algorithms- Objective question?
You are architecting a document storage system for next season's fashion designs. The system must support many different encryption algorithms to secure those documents. Security of the documents is the highest priority of the system. What are two valid concerns in this situation?
(Choose two.)
A. The most scalable solution is to use public key encryption for all encryption.
B. The system software must be able to be updated without decrypting all the files in the
system.
C. A single API should be used for all encryption algorithms allowing them to be used
interchangeably.
D. Each encryption algorithm should be deployed to its own server to keep deployment and
configuration simple.
E. Documents in the system can be stored unencrypted if the storage servers are properly
secured behind a firewall and DMZ.
Answer: B, C
Why answer A is not correct? Isn't this a concern, or it is interpreted as a idea. I think authors can have better understanding to explain this.
