質問 # 11
Which level of data protection can be configured across sites in a VxRail Stretched Cluster1?
- A. RAID 1/0
- B. RAID 1
- C. RAID 5
- D. RAID 6
正解：B
解説：
In a VxRail Stretched Cluster, RAID 1 can be configured across sites to provide data protection. RAID 1 (mirroring) ensures that data is replicated across two sites, providing high availability and data redundancy in case one site fails. This configuration helps maintain continuous operations and data integrity in a multi-site deployment.
質問 # 12
What is the maximum number of nodes supported in a VxRail cluster with 1 GbE networking?
