An administrator is managing a 4-node cluster with different hardware generations: Two G5 Nodes → 2 CPUs (12 cores), 1 SSD (1.92 TB), 2 HDDs (4 TB). Two G7 Nodes → 2 CPUs (16 cores), 2 SSDs (1.92 TB), 4 HDDs (4 TB). The cluster will be decommissioned from production and used for Disaster Recovery (DR) purposes with an RPO of 1 hour. What is the best approach when replacing G5 nodes without impacting performance?

I don’t think it’s C. A lines up better since Nutanix clusters push for balanced SSD resources per node to avoid performance issues, especially in DR with a low RPO. Matching the G7's 2 SSDs ensures you’re not creating a bottleneck. Pretty sure from exam reports this is what they're looking for.

I get why people are picking D, but I'd say A makes more sense for DR. Matching SSD count is key so you don't end up with storage bottlenecks on those new nodes. D is a trap option because hybrid type alone isn't enough to guarantee balanced performance.

C or A? I get why people say D because the cluster's already hybrid, but for DR with a tight RPO, having at least 2 SSDs (like A) would really help match G7 node performance. Pretty sure storage speed matters more here than just the type. Open to hearing if anyone has real-world experience proving otherwise.

Option D seems right to me, since the existing nodes are hybrid, so keeping the new node hybrid should maintain cluster consistency. But if the "best" means matching just storage speed and not type, would you still pick D? If DR required all-flash for some reason instead of hybrid that could change my answer.
