NEW QUESTION # 12
An engineer Is implementing a data migration scenario for a customer who has multiple FC LUNs across multiple third-party SAN arrays. The engineer wants to use Foreign LUN Import (FLI) for the migration.
What is a requirement on the destination NetApp ONTAP cluster for FLI?
- A. At least one FC port in initiator mode
- B. At least one FC port in target mode
- C. A valid NetApp XCP license
- D. A valid SnapMirror license
Answer: B
Explanation:
When using Foreign LUN Import (FLI) for migrating LUNs from third-party SAN arrays to a NetApp ONTAP system, one of the requirements is to have at least one Fibre Channel (FC) port configured in target mode on the destination NetApp ONTAP cluster. This configuration is necessary to facilitate the migration process as the target mode port will accept and manage incoming data from the source SAN arrays.
For additional details, refer to:
* NetApp Documentation on FLI
NEW QUESTION # 13
A customer has a two-node NetApp ONTAP cluster that Is hosting FC LUNs for 64 SAN hosts. An administrator is tasked to add 40 more hosts to the environment.
What two actions would the administrator need to take to avoid potential performance problems with the environment? (Choose two.)
- A. Configure additional SAN LIFs.
- B. Configure additional FC ports on existing hosts.
- C. Configure a higher queue depth on the target ports.
- D. Configure additional FC target ports.
Answer: A,D
Explanation:
When adding 40 more hosts to a two-node NetApp ONTAP cluster that is already hosting 64 SAN hosts, the following actions are necessary to avoid potential performance problems:
* Configure additional FC target ports: Increasing the number of Fibre Channel (FC) target ports on the storage nodes will help distribute the I/O load more evenly, reducing the risk of bottlenecks.
* Configure additional SAN LIFs: Adding more SAN Logical Interfaces (LIFs) will ensure that the increased number of hosts can connect efficiently, improving load balancing and path management.
These actions help maintain optimal performance and prevent congestion in the SAN environment.

* NetApp SAN Host Configuration Overview
* NetApp Best Practices for SAN (NetApp) (NetApp)
NEW QUESTION # 14
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.)
- A. Create an igroup with the ESXi hosts' WWNNs.
- B. Create an igroup with the ESXi hosts' WWPNs.
- C. Map the LUNs to the igroup.
- D. Configure CHAP authentication.
Answer: B,C
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 # 15
What are two benefits of implementing VLANs for NVMe/TCP configurations? (Choose two.)
- A. Reduced number of IPspaces
- B. Reduced number of broadcast domains
- C. Increased security
- D. Increased resiliency
Answer: C,D
Explanation:
Implementing VLANs for NVMe/TCP configurations provides several benefits, two of which are increased resiliency and increased security:
* Increased Resiliency: VLANs help segment the network traffic, reducing the risk of a single point of failure. By isolating NVMe/TCP traffic into specific VLANs, network issues can be contained within a VLAN, preventing them from affecting other parts of the network. This isolation ensures that disruptions are minimized and network resiliency is enhanced.
* Increased Security: VLANs provide an added layer of security by segregating traffic. This segregation ensures that NVMe/TCP traffic is isolated from other types of traffic, reducing the risk of unauthorized access or data breaches. VLANs help in enforcing stricter access controls and monitoring, thereby increasing the overall security of the network.
For more information on the benefits of VLANs in NVMe/TCP configurations, you can refer to NetApp's technical resources:
* Implementing and Configuring Modern SANs with NVMe-oF (NetApp).
* SAN Configuration Best Practices (NetApp Community).
NEW QUESTION # 16
A customer wants to enable CHAP authentication on their iSCSI sessions.
Which command should be used to set up the appropriate security policies and passwords?
- A. security login create
- B. igroup initiator modify
- C. vserver iscsi security create
- D. security certificate create
Answer: C
Explanation:
To enable CHAP (Challenge-Handshake Authentication Protocol) authentication on iSCSI sessions, the command vserver iscsi security create should be used. This command sets up the necessary security policies and passwords required for CHAP authentication, ensuring secure access to iSCSI targets.
For more details, refer to:
* NetApp Documentation on iSCSI Configuration (NetApp).
NEW QUESTION # 17
A customer has data in a LUN on an existing third-party SAN storage system that will be migrated to a new NetApp AFF A400 all-flash MetroCluster system. The host connected to the LUN is a Windows Server 2019 system.
In this scenario, which two methods are supported? (Choose two.)
- A. Foreign LUN Import in online mode
- B. SnapMirror Business Continuity
- C. Foreign LUN Import in offline mode
- D. Client-side copy of the data
Answer: A,C
Explanation:
To migrate data from a LUN on an existing third-party SAN storage system to a new NetApp AFF A400 all-flash MetroCluster system, the supported methods include:
* Foreign LUN Import in online mode: This method allows for data migration without significant downtime, enabling the system to continue serving data while the migration process is ongoing.
* Foreign LUN Import in offline mode: This method involves taking the LUN offline during the migration process, which may be necessary in certain scenarios to ensure data integrity.
For more details, refer to:
* NetApp Documentation on Foreign LUN Import
* NetApp Community on LUN Import Methods
NEW QUESTION # 18
When using tagged VLANs on Cisco Nexus switches for NVMe over TCP, which two changes must be made to enable jumbo frames? (Choose two.)
- A. Modify the appropriate broadcast domain in NetApp ONTAP software to use an MTU of 9216.
- B. Modify the Cisco Nexus switches to use an MTU of 9216.
- C. Modify the Cisco Nexus switches to use an MTU of 9000.
- D. Modify the appropriate broadcast domain in NetApp ONTAP software to use an MTU of 9000.
Answer: A,B
Explanation:
For enabling jumbo frames on Cisco Nexus switches for NVMe over TCP with tagged VLANs, the following changes are required:
* Modify the Cisco Nexus switches to use an MTU of 9216: Setting the MTU to 9216 ensures that the network can handle jumbo frames, reducing the number of packets needed for large data transfers and thus improving performance.
* Modify the appropriate broadcast domain in NetApp ONTAP software to use an MTU of 9216:
This setting must match the network configuration to ensure end-to-end support for jumbo frames, which is essential for optimizing performance in NVMe over TCP environments.
For additional information, refer to:
* NetApp Documentation on NVMe over TCP
* Cisco Documentation on Jumbo Frames

A storage administrator wants to increase security and optimize performance in a recently implemented SAN deployment.
What should the storage administrator configure to ensure initiator restriction to certain LIFs?
- A. Subnets
- B. Access list
- C. Network route
- D. Broadcast domain.
Answer: B
Explanation:
To increase security and optimize performance in a SAN deployment, configuring an access list is essential.
Access lists restrict initiator access to specific LIFs, ensuring that only authorized hosts can connect to the storage system. This helps in enhancing security by preventing unauthorized access and optimizes performance by controlling and managing the paths used for storage access.
