NEW QUESTION 32
You are asked to serve iSCSI LUNs in an existing SVM on your AFF A220 using ONTAP 9.5. You verified that the iSCSI license is configured on your cluster and that the iSCSI protocol is enabled.
Referring to the exhibit, what is needed to allow hosts to log into the iSCSI target?
- A. Create new igroups with the host IQNs.
- B. Map LUNs to the igroups.
- C. Add iSCSI to the data protocol of the existing LIFs.

Answer: B
NEW QUESTION 33
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 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.

- B. Add an additional switch between the hosts and cluster.
- C. Add new LIFs on the used ports.
- D. Add new LIFs on unused ports.
Answer: D

Answer: B,C,D
NEW QUESTION 36
Click the Exhibit button.
A 4-node cluster was expanded with two news nodes (Nodes 5 and 6). You are now attempting to set up four FC LUNs on the two new nodes that use the ps2 igroup name, although FC ping works. LUNs on the previous four nodes are discoverable, but the four new LUNs on the new controllers are not discoverable.
Referring to the exhibit, what is the problem?
- A. The portset must be configured to reflect Nodes 5 and 6.
- B. Igroup ps2 has the portset configured with the LIFs.
- C. Selective LUN Mapping (SLM) is not configured for this HA pair.
- D. The zones between the hosts and LIFs are from node-05 and node-06.
Answer: A
NEW QUESTION 37
You want to connect a NetApp AFF A700 to a 32 Gb FC switch. The ports need to connect at 32 Gb speed.

- B. The AFF A700 includes FC ports natively on the controller.
- C. You need to purchase a two-port or four-port unified I/O module that enables FC and Ethernet connectivity.
- D. The AFF A700 includes an additional FC I/O module that is already populated in each controller.
Answer: C
NEW QUESTION 38
