正解：A
質問 3：
What is NVRAM used forwhen a node performs a takeover?
A. The NVRAM contains only the metadata operations that were pending to the node that was taken over.
B. The NVRAM contains all the outstanding read operations that were pending to the node that was taken over.
C. The NVRAM contains all the outstanding write operations that were pending to the node that was taken over.
D. The NVRAM contains only the Snapshot copies that were pending to the node that was taken over.
正解：B
質問 4：
An administrator notices that the clustered Data ONTAP 8.2.3 controllers are less responsive than normal. You use On Command Performance Manager but do not see obvious problems, yet, this particular issue is constant. Users are starting to complain.
Which tool would you use to collect data to help diagnose this issue?
A. Performance Archive
B. Perfstat
C. Auto Support
D. Perfmon
正解：D
質問 5：
Exhibit:
Round-robin DNS has been configured for all data LIFs belonging to SVM1. There is a data LIF on every node of that 4-node cluster.
The administrator has reports from users of sporadic user access issues when accessing CIFS shares on SVM1. The administrator determines that one out of four attempts result in a "path not found error" message. The administrator believes that the issue is network related.
Referring to the exhibit, which statement is correct?
A. There is an issue with node clusterB-04's port e0d, causing "lif3" to be down.
B. "lif3" and "lif-4" are on different ports as "lif1" and "lif2".
C. "lif3" has been administratively configured down.
D. There are no issues found and all data LIFs are in a healthy status.
