NEW QUESTION 1

A customer is required to encrypt iSCSI traffic across their public network. In this scenario, which method will accomplish this task?

• A. dot1q
• B. IPsec
• C. NVMe
• D. CHAP

Answer: B

NEW QUESTION 2


Which two storage efficiencies have been enabled on the NVMe namespace that is shown in the exhibit? (Choose two.)

• A. deduplication
• B. compaction
• C. compression
• D. thin provisioning

Answer: B

NEW QUESTION 3

A customer is deploying a SAN cluster of A700 nodes and wants to ensure that the SAN cluster will maintain a quorum in the event of a rack level power failure. Which two statements are true in this scenario? (choose two.)

• A. Six nodes are required
• B. Four nodes are required
• C. Three racks are required
• D. Two racks are required

Answer: AC

Explanation:
The quorum rule states that to make changes to the configuration in our cluster, we need to have more than half of the nodes available. This prevents configuration conflicts if we lose connectivity between the nodes in our cluster.
So, if we have only 2 racks and 4 nodes we could never get more than half of the nodes available if one of those racks power fails.
We need 6 nodes separated on 3 racks, so we can have more than half of the nodes available if one of those racks power fails.

NEW QUESTION 4

You have finished deploying a Netapp AFF All SAN Array Cluster and want to test the persistent ports feature. In this scenario, how would you accomplish this task?

• A. Perform a takeover of a node
• B. Disconnect an FCP initiator port
• C. Disconnect an FCP target port
• D. Disable a SAN LIF

Answer: A

Explanation:
If we don't have OnCommand Insight, then we should not pull out a cable as test because it won't be detected properly.
Doing a planned takeover will meet the requirements asked. Table Description automatically generated

NEW QUESTION 8

You have a 4-node cluster with a FAS8200 HA pair and an AFF A300 HA pair. You need to migrate a LUN from a FAS8200 node to an AFF A300 node for faster performance.
Which method will non-disruptively migrate the LUN to the AFF A300 while retaining snapshots of the LUN on the FAS8200?

• A. You move the LUN.
• B. You relocate the aggregate.
• C. You move the volume.
• D. You copy the LUN.

Answer: D

NEW QUESTION 9

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.

NEW QUESTION 11

Which statement is correct regarding virtual machine alignment on VMware ESX?

• A. RDM LUNs do NOT suffer from alignment problems because they are accessed directly by VMs.
• B. A VMFS LUN with a LUN type of VMware, will always have properly aligned VMs.
• C. Alignment issues can occur on any protocol including FCP, iSCSI, FCoE, and NFS
• D. msinfo32 or mbrscan can be run for the ESX service console to check for proper alignment of VMs.

Answer: C

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

NEW QUESTION 13

You are testing FCP paths failures on a 2-node Netapp AFF All SAN Array and verify that persistent ports are correctly enabled. Before testing, a host sees four optimized paths to a LUN. You perform a
node takeover and re-check the host.
Which statement is true after the node takeover?

• A. The host sees four optimized paths to the LUN
• B. The host sees two non-optimized paths and two dead paths to the LUN
• C. The host sees two optimized paths and two non-optimized paths to the LUN
• D. The host sees two optimized paths and two dead paths to the LUN

Answer: A

Explanation:
Support for persistent ports
Beginning in ONTAP 9.8, persistent ports are enabled by default on All SAN Arrays (ASAs) that are configured to use the FC protocol. Persistent ports are only available for FC and require zone
membership identified by World Wide Port Name (WWPN).
Persistent ports reduce the impact of takeovers by creating a shadow LIF on the corresponding physical port of the HA partner. When a node is taken over, the shadow LIF on the partner node assumes the
identity of the original LIF, including the WWPNe. Before the status of path to the taken over node is changed to faulty, the shadow LIF appears as an Active/Optimized path to the host MPIO stack, and I/O is
shifted. This reduces I/O disruption because the host always sees the same number of paths to the target, even during storage failover operations.

NEW QUESTION 16

During maintenance of an AFF A250 node, you want to move the SAN LIFs that are members of a port set. In this scenario, which two statements are true? (choose two)

• A. You must disable SLM for the node that hosts the LIF
• B. You need to disable the zoning of the LIF WWPN
• C. The LIF must be removed from the port set
• D. You must take the SAN LIF offline

Answer: CD

Explanation:
If the LIF is a member of a port set, the LIF must have been removed from the port set before the LIF can be moved to a different node.
