NEW QUESTION 130
A customer wants to deploy NVMe/FC along with an existing FC SAN fabric using ONTAP 9.8. In this scenario, which two actions are correct? (choose two)
- A. Enable NVMe/FC on the existing FC SVM
- B. Upgrade your FC switches from 16GB to 32GB
- C. Create new zoning on fabric switches
- D. Use existing zoning on fabric switches
Answer: A,D
Explanation:
Because NVMe/FC simply swaps command sets from SCSI to NVMe, it is an easy transition to make. NVMe/FC uses the same FC transport and therefore the same hardware from the host, through the switch and all the way to the NVMe/FC target port on the storage array. Thus, NVMe/FC implementations can use existing FC infrastructure, including HBAs, switches, zones, targets, and cabling.

NEW QUESTION 131
An administrator is planning a hardware refresh and data migration from a Data ONTAP 7.3 system to new AFF A3-00 cluster that is using ONTAP 9.0.

Answer: D
NEW QUESTION 132
You have a 100GB volume with the space guarantee set to volume, This volume contains two space reserved 20 GB LUNs. Both LUNs are at 50% use. You then create a snapshot copy of the volume. No modifications were performed since the snapshot copy was completed, and all actions were performed using the CLI. In this scenario, how much free space does the volume have?
- A. 40 GB
- B. 20 GB
- C. 80 GB
- D. 60 GB
Answer: D
Explanation:
Both LUN created are inheriting the space reserved parameter from its volume parent, so both LUNs are thick provisioned using 20 GB each one of them and the snapshots have not increased because there has not been any changes since their creation
100GB - 20 GB - 20GB
