Exam NCP-MCI v6.10 topic 2 question 28 discussion

Actual exam question from Nutanix's NCP-MCI v6.10

Question #: 28
Topic #: 2

An administrator is managing a 4-node cluster, based on intermixed hardware as follows:
• Two G5 Nodes, 2 CPUs 12 Cores, 1 SSD 1.92 TB, 2 HHDs 4 TB
• Two G7 Nodes, 2 CPUs 16 Cores, 2 SSD 1.92 TB, 4 HDDs, 4 TB
G5 Nodes are going out of support and need to be replaced. This cluster will be decommissioned from production and used for Disaster Recovery purposes with 1 hour RPO.
What is the supported configuration when swapping G5 nodes without compromising performance?

A. New node must have at least 2 SSDs.
B. New node must be G7 or G8.
C. New node must have 2 CPUs with 12 cores.
D. New node must be hybrid.

Selected Answer: A

A. New node must have at least 2 SSDs. Reason: Your cluster is hybrid today and the remaining nodes (G7) each have 2× SSD for cache/oplog. To stay supported and avoid a performance dip when you replace the G5s, the replacement nodes should match the SSD count (≥2 SSDs) so read/write caching and hot-tier capacity aren’t the bottleneck. D (must be hybrid): true for support (don’t mix all-flash with hybrid), but by itself it doesn’t address performance parity. You could add a 1-SSD hybrid node and be supported, but you’d likely throttle performance. B/C: exact generation or CPU core counts don’t have to match for support; they’re not the key constraint here.
