NEW QUESTION 26
Your customer asks you to configure a newly installed FAS8300 for an FC host connection.
Referring to the exhibit, which step accomplishes this task?
- A. Configure the ports 0e and 0f as status admin up
- B. Configure the ports 0e and 0f as type of target
- C. Configure the ports 0e and 0f as status admin down
- D. Configure the ports 0e and 0f as a mode of CNA
Answer: B
Explanation:
To change the port type from initiator to target you need to take the port offline The ports need to be on target mode to present LUNs to the hosts.

NEW QUESTION 37
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 LIF
- B. Enable Jumbo frames on the IPspace
- C. Enable Jumbo frames on the network switch
- D. Enable Jumbo frames on the broadcast domain
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 41
You are configuring a VMware sphere host for FC access to a Netapp ONTAP cluster. In this scenario, which two tasks does Netapp recommend performing on the Vsphere host? (choose two)
- A. Set the queue depth on the host to 8
- B. Zone the host by using the host WWNNs
- C. Update the HBA driver
- D. Use the Netapp Virtual Storage Console to configure the host settings
Answer: C,D
Explanation:
Zoning the host using WWNNs is not recommended. Netapp always recommends to use WWPN to zone correctly.
We can not stablish a queue depth value because we don't have the amount of ports and hosts to calculate the recommended queue depth Installing VSC and updating the HBA driver are best practices recommended by Netapp You can find more information on this link:

You verify that your Windows 2016 host reports 200 GB free on lun1. However, lun1 shows 0 bytes free on the storage cluster.
What should you do to solve this problem?
- A. Change the LUN -space-reserve parameter to enabled.
- B. Change the LUN -space-allocation parameter to enabled.
- C. Rescan the LUN disk in your Windows host so that it will notify NetApp about the free space.

Answer: C
NEW QUESTION 48
You have a 4-node cluster with an AFF A300 HA pair and a FAS8200 HA pair. You plan on using the default storage efficiency settings. With inline data compaction, you estimate that you can save 6% of storage space. AFF A300 volumes that use under 5000 IOPS are moved to a FAS8200 using the volume move command.
In this scenario, what happens to the data after the volume is moved? (Choose two.)
- A. The existing data is not compacted.
- B. The existing data is compacted.
- C. The new written data is not compacted.
- D. The new written data is compacted.
Answer: C
NEW QUESTION 49
You are designing a new 4-node AFF A400 SAN cluster with 20 ISCSI hosts. Each AFF A400 node will have four data LIFs. Each ISCSI host needs to access every LUN over two LIFs per node on every SAN node.
In this scenario, which Netapp SAN feature enable this connectivity?
- A. Asymmetric namespace
- B. Port sets
- C. Selective LUN mapping
- D. HBA queue depth
Answer: B
Explanation:
SLM will choose 4 LIFs per node, being 8 LIF total (owner and HA partner), enabling portsets will help to limit the ports per node... that way we can stablish only 2 LIF per node.
Creating port sets and binding igroups to port sets
In addition to using Selective LUN Map (SLM), you can create a port set and bind the port set to an igroup to further limit which LIFs can be used by an initiator to access a LUN. If you do not bind a port set to an igroup, then all of the initiators in the igroup can access mapped LUNs through all of the LIFs on the node owning the LUN and the owning node's HA partner.
