In Huawei FusionCompute, which function needs to be enabled to enable virtual machines to migrate between CNA hosts with different CPU models?

Question

Options

• ACluster IMC strategy
• BCluster HANA optimization
• CSet/0 ring adaptation
• DCluster Guest NUMAB policy

• A
  73% (11)
• B
  13% (2)
• C
  7% (1)
• D
  7% (1)

Explanation

Cluster IMC (Instruction Migration Compatibility) strategy masks CPU feature flags at the cluster level, presenting VMs with a common baseline instruction set regardless of the underlying physical CPU model. This allows live migration between CNA hosts with different CPU generations because the VM never "sees" instructions that may not exist on the destination host.

Why the distractors are wrong:

• B (HANA optimization) tunes VM performance for SAP HANA database workloads - it has nothing to do with CPU compatibility across hosts.
• C (Set/0 ring adaptation) relates to CPU privilege ring levels (kernel vs. user mode isolation), not cross-model migration compatibility.
• D (Guest NUMA policy) controls how VM memory is allocated relative to NUMA topology for performance - it does not address CPU instruction set differences.

Memory tip: Think of IMC as "I Must be Compatible" - when your cluster has mixed CPU models, enable IMC so every VM sees a compatible, lowest-common-denominator CPU, making migration safe across the cluster.
