NEW QUESTION 75
You want to ensure maximum performance of iSCSI LUNs on an AFF A220.
In this scenario, which two actions will accomplish this task? (Choose two.)
- A. Enable flow control.
- B. Enable jumbo frames.
- C. Disable flow control.
- D. Configure virtual LAN (VLAN).
Answer: A,B
NEW QUESTION 76
You have deployed an AFF 400 systems for ISCSI workloads and want to ensure maximum performance to the hosts.
In this scenario, which two steps should be configured? (Choose two)
- A. Enable Jumbo frames on the IPspace
- B. Enable Jumbo frames on the LIF
- C. Enable Jumbo frames on the broadcast domain
- D. Enable Jumbo frames on the network switch
Answer: C,D
Explanation:
Changing the Network port settings at the broadcast domain level will change all ports in that broadcast domain sequentially, or one at the time. This will only cause a disruption if the port is a single point of failure.
Enable jumbo frames (typically MTU of 9000).All devices in the data path, including initiators, targets, and switches, must support jumbo frames. Otherwise, enabling jumbo frames actually reduces network performance substantially.

NEW QUESTION 78
A customer has a 4-node cluster consisting of a FAS8020 system and an AFF A220 that is running ISCSI workloads across two separate SVMs. The FAS8020 system is reaching end of support, so they add a new AFF A400 system to migrate workloads off the FAS8020 system. The customer wants to migrate data off the FAS8020 aggregate n1_aggr1 on SVM2 to the AFF A400 aggregate n5_aggr1 on SVM1.
- A. Aggregate reallocation
- B. Volume reallocation
- C. Volume rehost
- D. Volume move
Answer: C
Explanation:
Moving a Volume will only work if you are doing it within the same SVM
Volume Reallocation is used when you add new disks to an aggregate and you need to redistribute the data Aggregate Reallocation can be used only when you are moving data from an AFF filer to another AFF filer Rehosting a volume from one SVM to another SVM Volume rehost enables you to reassign NAS or SAN volumes from one storage virtual machine (SVM, formerly known as Vserver) to another SVM without requiring a SnapMirror copy. The volume rehost procedures depend upon the protocol type and the volume type. Volume rehost is a disruptive operation for data access and volume management.

NEW QUESTION 83
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 84
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)
- A. All LIFs from the SVM are connected to a single Ethernet switch
- B. Each SVM in an ISCSI configuration must have a minimum of one LIF per node
- C. Each SVM in an ISCSI configuration must have a minimum of two LIFs per node
- D. Each node in an ISCSI configuration must be connected to a minimum of two ethernet switches
Answer: C,D
Explanation:
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.
