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

You have a two node Netapp ONTAP cluster that is hosting FC LUNs for 90 SAN hosts. The hosts are experiencing occasional performance problems and receiving QFULL responses from the cluster
nodes. Which action would solve this issue?

• A. Increase the queue depth on the target ports
• B. Configure additional FC target ports
• C. Increase the queue depth on the initiator ports
• D. Configure additional FC ports on the hosts

Answer: B

Explanation:
Adding more FC initiators on host will not solve this bottle-neck situation, we can try to increase the queue depth but we need the number of hosts and the number of target ports to calculate it correctly.
We need to add more FC target ports on our storage to keep the load balanced and distributed You can find more information on this link

NEW QUESTION 5

You have a Netapp ONTAP cluster and are configuring ISCSI for some new hosts . You want to ensure that ISCSI connectivity can survive physical network failures.
In this scenario, which two features would help fulfill this requirement? (choose two)

• A. Broadcast domains
• B. Failover groups
• C. MPIO
• D. Interface groups

Answer: CD

Explanation:
Broadcast Domains are used to segment and create failover groups automatically... Broadcast Domain do not guarantee redundancy on ISCSI because failover groups are not used on ISCSI.

NEW QUESTION 6

When booting your NetApp storage system for the first time the system fails to boot.
What should you do first to address this problem?

• A. You turn off your storage system and disk shelves, and then turn on the disk shelve
• B. You then check the quick reference card that came with the disk shelf for information about LED responses.
• C. You re-download the boot image to the compact flash card, then reboot the system.
• D. You look for a description of the problem on the LCD and consol
• E. You then follow the instructions, if provided, on the LCD and console.
• F. You verify disk shelf compatibility and check the disk shelf IDs to verify that the disk shelf 1 (for DS14 series) must be connected to your system.

Answer: C

NEW QUESTION 9


A customer is using both FC and NVMe in a cluster. The customer needs to do some work on AFF_1. Referring to the exhibit, what will happen?

• A. The NVMe namespaces on AFF_2 will be available after takeover of AFF_1.
• B. The FC LUNs that use cluster interconnect to access the LUNs on AFF_1 will be unavailable after failover.
• C. The FC LUNs on node AFF_2 will be unavailable after failover of AFF_1.
• D. The NVMe namespaces on AFF_1 will be unavailable after takeover by AFF_2.

Answer: C

NEW QUESTION 10

A customer wants to move its iSCSI SAN data from the edge locations into the cloud for data analytics, while keeping the ability to access modify the data.
Which two combined solutions meet the customer's requirements in this scenario? (Choose two.)

• A. Use Microsoft Azure compute resources to access the near cloud AFF SnapMirror data for analytics.
• B. Deploy ONTAP Cloud at edge locations find use SnapVault to move the data into an AFF on-premises data center.
• C. Deploy ONTAP Select at edge locations and use SnapMirror to move the data to AFF near cloud with the NetApp Private Storage (NPS) service.
• D. Use Amazon Web Services (AWS) compute resources to access ONTAP Select data at the edge office locations for analytics.

Answer: AD

NEW QUESTION 11


You have a LUN owned by Node 01 and mapped using the default Selective LUN Map (SLM) configuration. You want to enable your host to access this LUN and facilitate future maintenance.
Which best-practice zone configuration accomplishes this task?

• A. Zone 1: HBA 0, LIF_1, LIF_3, LIF_5 and LIF_7 Zone 2: HBA 1, LIF_2, LIF_4, LIF_6 and LIF_8
• B. Zone 1: HBA 0, HBA 1, LIF_1, LIF_2, LIF_3, LIF_4, LIF_5, LIF_6, LIF_7, LIF_8
• C. Zone 1: HBA 0, LIF_1, LIF_3 Zone 2: HBA 1, LIF_2, LIF_4

NEW QUESTION 12

Referring to the exhibit, which two actions would you perform to ensure that each host has valid multipathing? (choose two)

• A. Verify that the VLANs are properly configured on the switches
• B. Verify that the VLANs are properly configured on the ONTAP cluster
• C. Verify that ALUA is enabled on the switches
• D. Verify that ISCSI service is started on the ONTAP cluster

Answer: AB

Explanation:
Iscsi is already started, we can not run those commands successfully if the protocol is not started ALUA is enabled on hosts, It is not enabled on switches
VLANs are configured on the Netapp and switches, they need to be properly configured on both sides to work correctly
