Question #2
An administrator is setting up a NetApp ONTAP AFF system for both NVMe/TCP and iSCSI.
Which task is required for SAN configuration?
- A . Configure CHAP authentication.
- B . Configure DH-HMAC-CHAP authentication.
- C . Configure LIFs.
- D . Configure IPsec.
Correct Answer: C
C
Explanation:
When setting up a NetApp ONTAP AFF system for both NVMe/TCP and iSCSI, a critical task required for SAN configuration is to configure Logical Interfaces (LIFs). LIFs are necessary for network connectivity and are used by both NVMe/TCP and iSCSI protocols to communicate between the storage system and the host.
The configuration of LIFs involves creating and managing these interfaces to ensure they are correctly mapped and available for use by the respective protocols. This step is essential for the SAN setup to function properly.
For more detailed steps on configuring LIFs, you can refer to NetApp’s documentation:

Question #3
What are two benefits of implementing VLANs for NVMe/TCP configurations? (Choose two.)
- A . Increased resiliency
- B . Reduced number of broadcast domains
- C . Increased security
- D . Reduced number of IPspaces
Correct Answer: AC
AC
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.

Question #4
A customer wants to configure an NVMe protocol-based NetApp ONTAP based storage system in a SAN environment.
What is used to configure the list of hosts?
- A . igroup
- B . Namespace
- C . Subsystem
- D . LUN
Correct Answer: C
C
Explanation:
When configuring an NVMe protocol-based NetApp ONTAP storage system in a SAN environment, a subsystem is used to configure the list of hosts. A subsystem in the NVMe context is an entity that groups NVMe namespaces (storage units) and presents them to the connected hosts. The hosts access these namespaces through the subsystem, allowing for efficient management and configuration of NVMe resources.
This configuration ensures that the appropriate hosts have access to the necessary namespaces for storage operations. This approach is critical in NVMe SAN environments to maintain high performance and manageability.

Question #7
What configuration must be applied for NVMe/FC?
- A . Create multiple initiator zones and multiple target zones.
- B . Configure igroup and IQN mapping.
- C . Enable NPV on all fabric switches.
- D . Enable NPIV on all fabric switches.
Correct Answer: D
D
Explanation:
When configuring NVMe/FC (NVMe over Fibre Channel), it is necessary to enable N_Port ID Virtualization (NPIV) on all fabric switches. NPIV allows multiple Fibre Channel initiators to share a single physical Fibre Channel port, which is crucial for NVMe/FC environments where efficient utilization of available ports is needed.
NPIV support enables the creation of virtual ports, which can significantly optimize the configuration and management of Fibre Channel fabrics, thus supporting NVMe/FC operations.

Question #8
A storage administrator has just completed an ISCSI implementation in a customer environment running VMware and needs to validate that the entire network path supports jumbo frames.
Which action should be taken?
- A . Ping from the host with fragmentation.
- B . Check the VMkernel adapter settings.
- C . Ping from the host without fragmentation.
- D . Check the broadcast domain settings.
Correct Answer: A
A
Explanation:
To validate that the entire network path supports jumbo frames after an iSCSI implementation, you should perform a ping test from the host with fragmentation.
This involves using the ping command with specific options to test jumbo frame support:
ping -M do -s 8972 <target_IP>
In this command:
-M do ensures the packets are not fragmented.
-s 8972 sets the packet size to 8972 bytes (9000 bytes MTU minus 28 bytes for the ICMP header). By confirming that the large packets are successfully transmitted without fragmentation, you can validate that the network path, including switches and adapters, supports jumbo frames.

Question #9
An administrator installs a new NetApp ONTAP system in a customer’s SAN environment. The customer wants to confirm that ALUA correctly changes the path states between Active/Optimized and Active/Nonoptimized.
Which event causes ALUA to change the path states?
- A . Shut down all FC LIFs on the HA partner node.
- B . Move the containing volume to the HA partner node.
- C . Shut down one FC LIF.
- D . Disconnect one FC cable on the node hosting the LUN.
Correct Answer: A
A
Explanation:
ALUA (Asymmetric Logical Unit Access) is a protocol used in SAN environments to manage paths between a host and its storage. It enables the host to recognize and manage paths to the LUNs more efficiently by designating paths as either "Active/Optimized" or "Active/Nonoptimized". A significant event, such as shutting down all FC LIFs on the HA partner node, will trigger ALUA to change the path states. This action effectively causes the storage paths to transition from the HA partner node to the local node, switching the path states from Active/Nonoptimized to Active/Optimized on the paths that remain active.

Question #10
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 . A valid SnapMirror license
- B . At least one FC port in initiator mode

Question #16
A LUN Is displaying 90% used space in the NetApp ONTAP CLI, but a Windows Server shows only 10% used space.
What is the first step to take to address this issue?
- A . Enable automatic resizing.
- B . Disable automatic resizing.
- C . Disable space allocation.
- D . Enable space allocation.
Correct Answer: D
D
Explanation:
When a LUN shows 90% used space in the NetApp ONTAP CLI but a Windows Server shows only 10% used space, the discrepancy is often due to how space allocation is handled between the two systems. Enabling space allocation ensures that the ONTAP system accurately reflects the actual space usage as reported by the host system, in this case, the Windows Server. This adjustment allows ONTAP to reclaim and manage space more effectively, aligning the reported usage between the ONTAP system and the host.
