質問 7：
An alert about RX errors on eth2 on a node is reported in the cluster. The administrator logs in to the CVM in question, checks the ping_* files in the data/logs/syststats folder, and notices intermittent ping loss.
The node in question has the following network configuration:

Which action should be used to troubleshoot without disrupting the VMs running on this node?
A. Check the port on the switch side for any errors
B. Remove eth3 from br0-up and monitor for new alerts
C. Replace the cable from eth2 to the switch
D. Enable balance-s1b on br0-up and monitor if a problem persists
正解：A

質問 8：
An administrator deploys Exchange on a Nutanix cluster. The administrator creates two containers with RF2 configuration:

Which changes to Storage Optimization should be used on the Exchange container to enhance I/O performance?
A. Inline compression and Deduplication
B. No data reduction
C. Inline compression and EC-X
D. Post process Deduplication only
正解：B

質問 9：
