- Encryption: enabled
- Deduplication and Compression: enabled
- vSAN Capacity Utilization: 60%
✑ Each vSAN node has the following configuration:
- VMware vSphere ESXi version: 6.5 Update 3
- CPU: 2 processors, 20 cores
- RAM: 768GB RAM.
- Disk: 2 Cache SSDs and 6 Capacity SSDs
- Network: 4 x 10GbE
Which three recommendations should the consultant make to ensure all data remains protected in the event of a vSAN failure? (Choose three.)

  • A. The Full data migration maintenance mode option must be chosen to protect the data during the upgrade.
  • B. The Ensure accessibility, migration maintenance mode option must be chosen to protect the data during the upgrade.
  • C. The upgrade process should be completed using host upgrade baselines in VMware vSphere Lifecycle Manager (vLCM).
  • D. The vSAN nodes should be upgraded to vSphere ESXi 7.0 U1.
  • E. The upgrade process should be completed using images in VMware vSphere Lifecycle Manager (vLCM).
