6. You are designing your high-availability solution. Because of the importance of
the database system you are required to have more than one independent
backup server running at all times. Which high-availability solution fits these
requirements?
A. Database mirroring
B. Log shipping
C. Clustering
D. Replication
Answers B and D are correct. Only log shipping and replication allow for
multiple independent backup servers. Database Mirroring can have only a
single backup server. Clustering does not allow for any independent backup
servers because of the shared storage requirement.
