質問 # 77
A customer has a legacy NetApp E-Series array serving FC LUNs. The customer purchases a new four-node NetApp AFF All SAN Array (ASA) C-Series replacement. The customer needs to migrate data from the E- Series array to AFF using native storage features.
Which NetApp technology meets this requirement?
正解：D
解説：
Foreign LUN Import (FLI) is ONTAP ' s native block-level migration technology for importing SAN LUN data from an external source array into native ONTAP LUNs. FLI operates at the storage layer rather than requiring host file-copy utilities and supports controlled migration workflows across heterogeneous SAN environments. ONTAP initiator ports access the source array ' s target ports through the FC fabric, after which an import relationship is established between the source LUN and the destination ONTAP LUN. SyncMirror is used for synchronous plex mirroring within MetroCluster architecture, while SnapMirror and BlueXP replication are ONTAP replication technologies and do not provide this foreign-array LUN import workflow.
The precise source-array/model combination must also be validated against NetApp interoperability requirements. Relevant topics include FLI discovery, FC zoning, foreign LUNs, import relationships, and migration validation.
質問 # 78
When using SnapMirror active sync between two clusters, which NetApp service orchestrates failover in case the primary storage system fails?
正解：D
解説：
ONTAP Mediator provides the quorum and health information required for automated failover in a SnapMirror active sync configuration. It operates as an independent third party that monitors communication with both participating ONTAP clusters and provides information that enables ONTAP to determine whether the primary system is unavailable. During an automatic unplanned failover, ONTAP uses Mediator-assisted quorum information before allowing the surviving cluster to serve the protected workload. The Mediator does not carry application data and is not equivalent to MetroCluster Tiebreaker. Active IQ provides monitoring and analytics, while SANtricity manages E-Series storage. NetApp requires a properly configured Mediator for automated failover functionality in applicable SnapMirror active sync configurations. Relevant SAN ONTAP topics include SnapMirror active sync, ONTAP Mediator, quorum, automated unplanned failover, and synchronous replication.
質問 # 79
A customer is deploying an IP-based SAN on a NetApp AFF All SAN Array (ASA) system. A solution should be used that will increase security and improve reliability.
What is a network best practice for IP-based SAN when implementing AFF ASA infrastructure solutions?
正解：B
解説：
Separate VLANs are a recommended design practice for IP-based SAN traffic because they provide logical network segmentation and enable independent broadcast domains. ONTAP VLANs can separate storage traffic by function or network path even when the underlying physical switching infrastructure is shared. For SAN redundancy, NetApp also recommends separate Ethernet networks and multiple paths so that failure of one network does not eliminate storage connectivity. VLAN separation additionally limits unnecessary broadcast-domain exposure and provides clearer operational boundaries for iSCSI or NVMe/TCP traffic. An MTU of 1500 is supported but does not inherently provide the requested security and reliability improvement, while simply using routed networking is not the relevant SAN best practice. Therefore, separate VLANs provide the appropriate segmentation and path-isolation characteristics for an AFF ASA IP SAN design.
質問 # 80
When using FCP, what is the minimum number of FC switches needed to redundantly attach three ESXi hosts?
正解：A
解説：
When using Fibre Channel Protocol (FCP), the minimum number of FC switches needed to redundantly attach three ESXi hosts is 2. This setup ensures that each host has multiple paths to the storage, providing high availability and fault tolerance. Each ESXi host should be connected to both switches, allowing for continuous operation even if one switch fails.

* NetApp Documentation on FC Switch Configurations
* NetApp Community Discussion on Redundant FC Setup
質問 # 81
An administrator is configuring ISCSI on an SVM and requires that all network traffic Is encrypted. What must be done to satisfy this requirement?
正解：A
解説：
To ensure that all network traffic is encrypted for iSCSI on an SVM, configuring IPsec is required. IPsec (Internet Protocol Security) provides end-to-end encryption for IP traffic, ensuring that data transmitted over the network is secure.
For more details, refer to:
* NetApp Documentation on Configuring IPsec
