NCP-BC practice question 1 of 25

When designing a Disaster Recovery strategy to an NC2 cluster using MST, which technical limitation impacts the Recovery Plan and workload compatibility?

Answer options

A: The "Zero Compute" configuration requires manual restoration of workloads (automated failover is not supported), and MST currently only protects AHV VMs. Correct answer

B: To ensure resilience on NC2, both MST DR and "Cluster Protect" features must be configured simultaneously on the same cluster.

C: Automated failover is natively supported in the "Zero Compute" configuration but strictly requires configuring an external IPAM to manage and reassign IP addresses.

D: The "Pilot Light" configuration allows to select multiple on-premise clusters as sources within a single protection policy to automate the failover of AHV and ESXi VMs.

Correct Answer:

A. The "Zero Compute" configuration requires manual restoration of workloads (automated failover is not supported), and MST currently only protects AHV VMs.

Explanation

The Zero Compute configuration in NC2 DR maintains only storage resources without active compute, requiring manual intervention to restore workloads during failover. MST (Migrate, Synchronize, and Transform) is specifically designed for AHV-based workloads and doesn't support ESXi VMs, creating a significant workload compatibility limitation when designing DR strategies for heterogeneous environments.

Why Incorrect

B. MST DR and Cluster Protect are independent features that don't require simultaneous configuration.
C. Zero Compute by definition cannot support automated failover due to lack of compute resources.
D. Protection policies typically establish one-to-one relationships between source and target clusters.
