An administrator is trying to configure a multiple-hop Cisco MDS switch and is receiving the error shown in the exhibit.
In this scenario, which action will solve this problem?

1. A. Configure the physical link of interface ext17 as an F_Port.
2. B. Configure the external interface to a different virtual SAN (VSAN) on both ends.
3. C. Connect the external link to a Cisco MDS switch.
4. D. Turn N_Port ID virtualization (NPIV) off.

Correct Answer: C

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?

1. A. SCSI thick provisioned LUN
2. B. SCSI thin provisioned LUN
3. C. NetApp thin provisioned volume
4. D. NetApp thick provisioned volume

Correct Answer: B
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.

You are configuring a Windows Server 2019 system to attach to an ISCSI presented LUN. There are multiple physical paths from the Windows Server to the Netapp Cluster. Which two changes are required
to the Windows Server to enable multipath? (choose two)

1. A. Add an Ethernet network adapter
2. B. Select the “enable multi-path” checkbox on the ISCSI software initiator
3. C. Add a converged network adapter (CNA)
4. D. Enable MPIO by selecting the option in the MPIO properties administrative application

Correct Answer: BD
Select Enable multi-path, select Automatically restore this connection when the computer starts or Add this connection to the list of Favorite Targets, and then click Advanced

You are a system administrator and responsible for a Netapp AFF A800 2-node ONTAP 9.8 cluster that is used only for SAN. Your SAN uses FC and FCoE on the same Cisco switches. You want to add
NVMe from the ONTAP controller to the same Cisco fabric. Which two statements are correct in this scenario? (choose two)

1. A. The same SVM can serve both the FC and the FCoE protocols
2. B. The same SVM cannot serve both the FC and the NVMe protocols
3. C. FCoE and NVMe can share the same physical port
4. D. FC and NVMe can share the same 32 GB physical port

Correct Answer: AD
FC and FC-NVMe can share the same 32 Gb physical port
The same SVM can serve both FC and NVMe protocols using the same physical infraestructure wiith different LIFs
FCoE and NVMe can NOT share the same infraestructure, they go trough different physical hardware

You are installing an AFF A250 system with ONTAP 9.8 software. Your customer asks you about the recommended LIF configuration for the ISCSI protocol. In this scenario, which two statements are correct
(choose two)

1. A. Each node in an ISCSI configuration must be connected to a minimum of two ethernet switches
2. B. All LIFs from the SVM are connected to a single Ethernet switch
3. C. Each SVM in an ISCSI configuration must have a minimum of two LIFs per node
4. D. Each SVM in an ISCSI configuration must have a minimum of one LIF per node

Correct Answer: AC
It is recommended that all SVMs in ISCSI configurations have a minimum of two LIF's per node in separate Ethernet networks for redundancy and MPIO across multiple paths.
