NEW QUESTION # 12
A customer Is setting up a four-node NetApp AFF cluster for use with NVMe/TCP and wants to use automatic host discovery.
Which protocol is used for the discovery of controllers?
Answer: D
Explanation:
For automatic host discovery in a four-node NetApp AFF cluster using NVMe/TCP, the protocol used is mDNS (Multicast DNS). mDNS allows for the discovery of controllers and other networked devices without the need for a centralized DNS server, simplifying the setup process in environments that support NVMe over TCP.
For further information, refer to:
* NetApp Documentation on NVMe/TCP
* NetApp Community on Host Discovery
NEW QUESTION # 13
An SVM is created for FCP traffic. LUNs must be created to share with ESXi hosts for datastores. Which two items must be configured after the LUN is created, for this to happen? (Choose two.)
Answer: C,D
Explanation:
For configuring LUNs to share with ESXi hosts for datastores in an SVM created for FCP traffic, the following steps are necessary after creating the LUN:
* Create an igroup with the ESXi hosts ' WWPNs: This step involves defining an initiator group that includes the WWPNs of the ESXi hosts that need access to the LUN.
* Map the LUNs to the igroup: This step assigns the LUN to the created igroup, allowing the ESXi hosts to access the LUN.
For further details, refer to:
* NetApp Documentation on LUN and igroup Configuration
NEW QUESTION # 14
An administrator provisions several LUNs on a four-node NetApp AFF cluster using default settings. Each AFF node has four FC LIFs. The configuration is modified to limit the target paths to two LIFs per node.
Which NetApp ONTAP command will verify initiator group visibility for each LIF?
Answer: C
Explanation:
The configuration described is a portset use case. NetApp states that portsets can be bound to igroups to restrict which SAN LIFs an initiator can use to access mapped LUNs, which is especially useful when a node has more than two LIFs and access must be limited to a subset. The lun portset show command displays each portset together with its protocol, Port Names representing participating LIFs, and the igroups bound to that portset. That output directly verifies which igroup has visibility through which LIFs. lun mapping show primarily displays LUN-to-igroup mappings and SLM reporting nodes; it does not provide the same direct LIF membership view. Therefore, the supplied V9.02 answer D requires correction to C. Relevant SAN ONTAP topics are portsets, igroup binding, LIF path restriction, SLM, and SAN path visibility.
NEW QUESTION # 15
A customer has created an SVM for their SAN workloads. They now want to configure the SVM to use NVMe/FC. Which two steps are needed to accomplish this task? (Choose two.)
Answer: C,D
Explanation:
To configure an SVM to use NVMe/FC, the following steps are necessary:
* Add the FC protocol: This step involves enabling the Fibre Channel protocol on the SVM, which is required to support NVMe over Fibre Channel.
* Create an NVMe/FC LIF: Logical Interfaces (LIFs) must be created to handle NVMe traffic over the Fibre Channel network. These LIFs enable the NVMe namespace access to the host systems.
These steps ensure that the SVM is correctly set up to use NVMe/FC, allowing for efficient and high- performance access to NVMe storage.

NEW QUESTION # 16
A customer has a 10GB volume with an 8GB LUN that is using 7GB. The snapshot policy is hourly and retains 48 snapshots. After a ransomware attack that encrypts all files on the LUN, the customer notices that all snapshots are gone.
What could cause this behavior?
Answer: B
Explanation:
The likely cause for the disappearance of all snapshots after a ransomware attack that encrypted all files on the LUN is the Snapshot autodelete feature. When the volume becomes full due to the encryption, the autodelete feature removes older snapshots to free up space, preventing the volume from running out of space and ensuring write operations can continue.
For more information, see:
* NetApp Documentation on Snapshot Autodelete
* NetApp Community Discussion on Snapshot Deletion
