Final answer:
A Node Majority quorum configuration can sustain the loss of just under one-half of the cluster nodes, as it requires more than half of the nodes to be online to maintain cluster operations. A) Node Majority
Step-by-step explanation:
The type of quorum configuration that can sustain the loss of one-half of the cluster nodes (rounded up), minus one, is A) Node Majority.
In a Node Majority configuration, the cluster can continue to function as long as more than half of the cluster nodes are online which provides resilience to node failures. Each node gets one vote, and the majority of votes determines the availability of the cluster. A Node and Disk Majority or a Node and File Share Majority would require an additional witness (disk or file share) for a vote, which is not necessary if you want the cluster to withstand the loss of just under half of its nodes.
