You create an availability group named HaContoso that has replicas named Server01/HA, Server02/HA, and
Server03/HA.
Currently, Server01l/HA is the primary replica.
You need to ensure that the following requirements are met:
Backup operations occur on Server02/HA.
If Server02/HA is unavailable, backup operations occur on Server03/HA.
Backup operations do not occur on Server01/HA.
How should you configure HaContoso?
A.
Set the backup preference of HaContoso to Prefer Secondary.
Set the backup priority of Server02/HA to 20.
Set the backup priority of Server03/HA to 10.
B.
Set the backup preference of HaContoso to Secondaryonly.
Set the backup priority of Server02/HA to 20.
Set the backup priority of Server03/HA to 10.
C.
Set the backup preference of HaContoso to Secondaryonly.
Set the backup priority of Server02/HA to 10.
Set the backup priority of Server03/HA to 20.
D.
Set the exclude replica of Server01/HA to true.
Set the backup priority of Server02/HA to 10.
Set the backup priority of Server03/HA to 20.

if you use Secondaryonly backups will be done only on the secondary replica.
Imagine the secondary replica fails? => no backups
so A is correct because in case of failure it will go to the 3rd replica to take a backup

No. Correct answer is B.

“Prefer Secondary
Specifies that backups should occur on a secondary replica except when the primary replica is the only replica online. In that case, the backup should occur on the primary replica.”
But the requirement is “Backup operations do not occur on Server01/HA.”
So choose “Secondaryonly” which is B.

The two candidates are : “A” & “B”
“A”(Secondary Prefer) is false because, in case of Replica02 and Replica03 are offline the backup will occur on the Primary which is not good ([…]Backup operations do not occur on Server01/HA[…])
“B” is the Correct Answer
