質問 101
An administrator is configuring their existing Ethernet network switches to provide ISCSI LUNs to several servers. The network switches are also used for other traffic from various hosts. In this scenario, which statement is true?
- A. Configure the MTU size to be larger on the switch and storage than on the host.
- B. Netapp recommends using the same LIFs for NFS and ISCSI traffic
- C. Increase the ratio of access ports to trunk ports to 2:1
- D. Use multiple VLANs to isolate traffic from other network traffic
正解: D
解説:
VLANs offer specific benefits, such as increased security and improved network reliability that you might want to leverage in iSCSI.

質問 102
You have an 8-node AFF A400 ONTAP 9.8 cluster that is serving FC and ISCSI LUNs. You have three SVMs for FC and one SVM for ISCSI, each for separate VMware VSphere clusters. The VMware clusters are on separate, non-routable, networks. You are asked to set up SnapCenter software for backups of the Virtual machine datastores. What is the minimum management LIF count that is needed to satisfy this requirement?
- A. eight
- B. four
- C. two
- D. one
正解: B
解説:
You need to configure an SVM management LIF to link it with snapcenter... every SVM will need 1 management LIF minimun and we have 4 SVM You can find more information on this link:

質問 105
As a system administrator, you perform a routine check of available storage space on your FAS2750. You notice that the vol_1 volume is approaching 100% capacity. The volume is configured with the space guarantee set to volume and the LUN reservation is disabled. You want to free up space in the volume without increasing its size.
Which action would accomplish this task?
- A. Increase the aggregate size.
- B. Increase the Snapshot Reserve.
- C. Increase the size of the LUN.
- D. Use deduplication.
正解: A
質問 106
You have a 4-node FAS8200 A300 cluster that are using ONTAP 9.3 default settings. For faster performance, you move a volume with LUNs from a node on the FAS8200 to a node on the AFF A300. You determine that your SAN host is still using all active/optimized FC paths to the FAS8300 HA pair.
What do you need to troubleshoot to move all active/optimized FC paths to the AFF A300 HA pair?
- A. reporting nodes list
- B. host MPIO and ALUA
- C. igroup WWPNs
- D. LUN mapping
正解: A
質問 107
While changing the network connections on your ONTAP cluster from twinax to fiber, the ports experience network connectivity issues. You want to verify which speeds the ports support and ensure that you have supported transceivers. In this scenario which two actions would accomplish this task (choose two)
- A. Use hardware universe to determine the supported port speeds
- B. Use the interoperability matrix tool to determine the supported port speeds
- C. Use the interoperability matrix tool to determine the supported transceivers
- D. Use hardware universe to determine the supported transceivers
正解: A,D
解説:
Hardware universe will show information about port speeds and transceiver compatbility You can find more information on this link:
