NEW QUESTION 1

An administrator is configuring their existing Ethernet network switches to provide ISCSI LUNs to several servers. The network switches are also used for other traffic from various hosts. In this scenario,
which statement is true?

• A. Increase the ratio of access ports to trunk ports to 2:1
• B. Configure the MTU size to be larger on the switch and storage than on the host.
• C. Use multiple VLANs to isolate traffic from other network traffic
• D. Netapp recommends using the same LIFs for NFS and ISCSI traffic

Answer: C

Explanation:
VLANs offer specific benefits, such as increased security and improved network reliability that you might want to leverage in iSCSI.

NEW QUESTION 2

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 a mode of CNA

• C. Configure the ports 0e and 0f as status admin up
• D. Configure the ports 0e and 0f as status admin down

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.

• B. Add new LIFs on unused ports.
• C. Add new LIFs on the used ports.
• D. Reduce the queue depth on the used ports.

Answer: B

NEW QUESTION 6

A company has 20 ESX hosts. Ten of the hosts are connected using FC, and the rest are connected over iSCSI. The FC host HBA queue depth is set to 32, and the iSCSI LUN queue depth is set to 64. The FC hosts are now experiencing random connectivity issues.
In this scenario, what would be the reason for the disconnects?

• A. The FC host has a lower queue depth.
• B. According to the IMT, unsupported HBA firmware is in use.
• C. All of the hosts are part of the same cluster.
• D. The queue depth is not consistent across the cluster.

Answer: A

NEW QUESTION 7

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. Port sets
• B. HBA queue depth
• C. Selective LUN mapping
• D. Asymmetric namespace

Answer: A

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.
