A company has two departments. Both departments own several EC2 instances. Department A has a requirement to backup EBS volumes every 12 hours and the administrator has set up a Data Lifecycle Policy in DLM for their instances. Department B requires a similar Data Lifecycle Policy as well for their instances. However they prefer the schedule to run every 24 hours. The administrator has noticed that 2 EBS volumes are owned by both the departments at the same time. How can the administrator setup the Data Lifecycle Policy for the Department B?

A. Add a tag for EBS volumes that Department B has owned. Set up a Data Lifecycle Policy based on the tag. For the EBS volumes owned by two departments, snapshots will be taken every 12 hours and 24 hours

B. Add a tag for EBS volumes that Department B has owned. Set up a Data Lifecycle Policy based on the tag. For the EBS volumes owned by two departments, snapshots will not be taken, as there is a schedule conflict between two policies. However other EBS volumes are not affected.

C. Add a tag for EBS volumes that Department B has owned. Set up a Data Lifecycle Policy based on the tag. For the EBS volumes owned by two departments, snapshots will be taken every 12 hours as 12 hours schedule takes priority

D. Add a tag for EBS volumes that Department B has owned except the EBS volumes owned by two departments. Set up a Data Lifecycle Policy based on this tag. For the EBS volumes owned by two departments, snapshots are taken every 12 hours due to the policy of Department A
