Your company has a main office and a branch office.
You plan to implement a failover cluster named Cluster1 to host an application named Appl.
The data of App1 will replicate to all of the nodes in Cluster1.
Cluster1 will contain two servers.
The servers will be configured as shown in the following table.

The cluster nodes will not use shared storage.
The branch office contains two file servers named Server3 and Server4.
You need to ensure that App1 fails over automatically to another server if a single node in Cluster1 fails.
What should you do? More than one answer choice may achieve the goal. Select the BEST answer.

A.
Add Server1, Server2, and Server3 to a Network Load Balancing (NLB) cluster.

B.
Add Server3 as a file share witness for Cluster1.

C.
Add Server3 and Server4 to a new failover cluster named Cluster2. Install App1 on Cluster2.

D.
Add Server3 as a node in Cluster1.

Explanation:
Notes:
We have a two-node cluster. We can either use a quorum disk, a witness file share, or an additional node to still maintain a majority for the operation of the cluster
in case of failure of a single node. A witness file share on a “witness location” is compared with an additional node in the branch office, the better Solution.
