Which two solutions would alleviate the QFull errors and performance problems? (Choose two.)
- A. Reduce FC HBA gueue depth on the hosts.
- B. Remove Selective LUN Mapping (SIM) from the 4-node FAS9000 cluster.
- C. Download the latest FC HBA driver, firmware, and BIOS, and deploy them on the hosts.

質問 16
An administrator is configuring a SAN-only cluster. The data room that houses four AFF A220 controllers is small and not able to house the DS224C shelves. The administrator proposes to rack the shelves in a separate room that is 40 meters away from the controllers.
In this situation, how would you properly cable the controllers to the shelves?
- A. Use multimode active copper cables.
- B. Use multimode active optical cables.
- C. Use multimode passive copper cables.

質問 17
In an NVMe/FC environment, the host cannot discover the namespace on the AFF system. Referring to the exhibit, what is the problem?
- A. The NVMe service is not running on the SVM
- B. The host MPIO drivers are not installed
- C. NVMe is not supported on the FC adapter
- D. The NQN is not correct
正解: D
解説:
We would not be able to run that command if NVMe is not enabled
NVMe is supported on the same SVM along with FC protocol
The multipath tool on NVMe is called ANA
NQN needs to be correctly declared on the subsystem to map the new NVMe resources
質問 18

- A. Add a converged network adapter (CNA)
- B. Select the "enable multi-path" checkbox on the ISCSI software initiator
- C. Add an Ethernet network adapter
- D. Enable MPIO by selecting the option in the MPIO properties administrative application
正解: B,D

質問 20
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. Use existing zoning on fabric switches
- B. Enable NVMe/FC on the existing FC SVM
- C. Create new zoning on fabric switches
- D. Upgrade your FC switches from 16GB to 32GB
正解: A,B
解説:
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.

質問 21
You need to move a LUN non-disruptively from an AFF A200 HA pair to an AFF A700 HA pair within the same 4-node cluster using the steps shown below.
1. Scan the host OS to discover all paths to the LUN.
2. Execute the lun move command to move the LUN to the AFF A/00 HA pair.
3. Remove the AFF A200 HA pair from the reporting-nodes list.
4. Add the AFF A700 HA pair to the reporting-nodes list.
What is the correct sequence in performing, these steps?
- A. 4, 3. 2. 1
- B. 3, 2, 1,4
- C. 4. 1, 2, 3
- D. 1, 2, 3. 4
正解: C
質問 22
You are in the testing phase of a newly deployed NVMe over Fibre Channel (NVMe/FC) SAM environment using Asynchronous Namespace Access (ANA). You are unable to successfully fail over a workload.
In this scenario, which action should you perform?
- A. Verify that the host operating system version supports ANA.
- B. Verify that the NVMe/FC host utilities kit is installed for ANA.
- C. Verify that multi-initiator zoning is configured on the FC switches.
- D. Verify that the DM-Multipath driver is configured for ANA.
正解: D
質問 23
You want to move a SAN LIF and preserve its configuration information and avoid rezoning the switch fabric. In this scenario, which two steps must be performed to fulfill this goal? (Choose two)
- A. Move the SAN LIF to another node in a cluster on existing storage virtual machine (SVMs)
- B. Keep the SAN LIF online before it is moved
- C. Move the SAN LIF to another node in a cluster on a different storage virtual machine (SVMs)
- D. Take the SAN LIF offline before it is moved
正解: A,D
解説:
Moving SAN LIFs
If a node needs to be taken offline, you can move a SAN LIF to preserve its configuration information, such as its WWPN, and avoid rezoning the switch fabric. Because a SAN LIF must be taken offline before it is moved, host traffic must rely on host multipathing software to provide nondisruptive access to the LUN. You can move SAN LIFs to any node in a cluster, but you cannot move the SAN LIFs between storage virtual machines (SVMs).

質問 24
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. The Mode system only serves FC LUNs to a Windows 2012Rs server cluster that needs to remain connected after migration Referring to the scenario, which method would be used for the LUN migration.
- A. Foreign LUN import (FLI)
- B. 7-Mode Transition Tool (7MIT)
- C. Unified Host Utility Kit

質問 25
An administrator is asked to provision a SAN environment in which host applications can monitor LUN space and performance space reclamation.
Which LUN type would satisfy these requirements?
- A. SCSI thick provisioned LUN
- B. SCSI thin provisioned LUN
- C. NetApp thin provisioned volume
- D. NetApp thick provisioned volume
正解: B
解説:
Automatic host-side space management with SCSI thinly provisioned LUNs
If your host supports SCSI thin provisioning, you can enable the space-allocation option in ONTAP to turn on automatic host-side space management.

質問 27
You are configuring FC ports on front-end SAN switches for a 4-node Metrocluster configuration across two data centers. You need to ensure that each data center serves FC LUNs when an FC port goes offline in one data center. In this scenario, which front end switch setting must be modified to avoid overlap when a new port comes online?
- A. WWPN reject
- B. ANA mapped
- C. NPIV enabled
- D. WWNN reject
- E. NPIV reject
正解: C
解説:
Best practice: NPIV is required for FC LIFs to operate correctly. Before creating FC LIFs, make sure that any fabrics attached to an ONTAP system have NPIV enabled.
