I agree with Justa. Deduplication should reduce the load on the host CPU, not increase it. Maybe the exam writer needs to update their knowledge on the topic.

I also believe that statement D is incorrect. Deduplication actually offloads the CPU by reducing the amount of data that needs to be processed.

Hmm, this is a tricky one. I'm pretty sure that statement D is incorrect, as both source-end and target-end deduplication actually improve host CPU performance by reducing the amount of data that needs to be transferred.
