Q1. - (Topic 2)
What is considered when selection LS mirror copy? (choose three)

Q9. - (Topic 2)
Which statement is true about a SnapMirror destination vserver?

B. It must be in the same cluster as the source Vserver
C. It must be created with the same language type as the source Vserver.
D. It must have a different storage efficiency policy than the source Vserver.
Answer: C
Explanation:
Training material: Clustered_Data_ONTAP_82_Data_Protection_Guide How volume SnapMirror works with deduplication You can use volume SnapMirror to replicate a deduplicated volume regardless of size of the volume and logical data in the volume. When using volume SnapMirror with deduplication, you must consider the following information: You can enable deduplication on the source system, the destination system, or both systems.
The shared blocks are transferred only once. Therefore, deduplication also reduces the use of network bandwidth. When the volume SnapMirror relationship is broken, the default deduplication schedule is applied at the destination storage system. When configuring volume SnapMirror and deduplication, you should coordinate the deduplication scheduleand the volume SnapMirror schedule. You should start volume SnapMirror transfers of a deduplicated volume after the deduplication operation is complete. This schedule prevents the sending of undeduplicated data and additional temporary metadata files over the network. If the temporary metadata files in the source volume are locked in Snapshot copies, these files consume extra space in the source and destination volumes.
Q10. - (Topic 3)
Which are types of failover groups? (choose all that apply)
A. System-defined
B. User-defined
C. Next Available
D. Priority
E. Clusterwide
Answer: A,B,E
Explanation: Types of failover groups
Failover groups for LIFs can be system-defined or user-defined.
Additionally, a failover group called clusterwide exists and is maintained automatically.
Failover groups are of the following types:
System-defined failover groups: Failover groups that automatically manage LIF failover
targets on a per-LIF basis.
This is the default failover group for data LIFs in the cluster.
For example, when the value of the failover-group option is system-defined, the system will
automatically manage the LIF failover targets for that LIF, based on the home node or port
of the LIF.
Note: All the network ports should be assigned correct port roles, and all the network ports
of the same role should be in the same subnet.
User-defined failover groups: Customized failover groups that can be created when the
system-defined failover groups do not meet your requirements.
For a system with ports of the same role connected to multiple subnets, each LIF requires
a user-defined failover group with a failover group for each subnet.
You can create a failover group consisting of all 10-GbE ports that enables LIFs to fail over
only to the high-bandwidth ports.
Clusterwide failover group: Failover group that consists of all the data ports in the cluster.
This is the default failover group for the cluster-management LIFs only.
For example, when the value of the failover-group option is cluster-wide, every data port in
the cluster will be defined as the failover targets for that LIF."
