An EMC Avamar backup administrator must configure root-to-root Disaster Recovery (DR)
replication from two single-node servers to a single, larger multi-node server, and is asking
for DR methods in the event of a failure of one of the single-node servers. What advice do
you give this administrator to protect the data on the single-node servers?

A.
The DR full copy replication method is one-to-one, so the administrator will either
need a target single-node server for each source-single node, or will need to switch to
standard replication.

B.
The multi-node server can accept DR full copy from both single-node servers, but
can only stand in for one of the single-node servers.

C.
The standard bi-directional replication method between the single-nodes and the
multi-node will allow the multi-node to stand in for both of the two single-nodes.

D.
A third single-node will need to be purchased and dedicated to both of the existing
single-nodes for DR protection.
