質問 # 17
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?
正解：C
解説：
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 ).
質問 # 18
An administrator has a two-node NetApp ONTAP cluster that is hosting FC LUNs for 90 SAN hosts. The hosts are experiencing occasional performance problems and receiving QFULL responses from the cluster nodes.
Which action would resolve this issue?
正解：B
解説：
A QFULL response indicates that the storage controller's FC target-port command queue has reached its supported capacity and cannot accept additional SCSI commands. With 90 hosts generating I/O, excessive fan- in to the existing target ports can exhaust available queue resources. Configuring additional FC target ports allows host connections and queued commands to be distributed across more storage-side target resources, reducing pressure on each individual target port. Increasing initiator queue depth would worsen the condition because hosts could submit more outstanding commands. Similarly, increasing target-port queue depth is not the appropriate administrator-controlled remedy presented here because the physical target adapter has defined queue limits. NetApp recommends planning host fan-in carefully to avoid QFULL conditions.
Relevant topics include FC queue depth, target-port fan-in, QFULL responses, SAN scalability, and FC target- port design
質問 # 19
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
質問 # 20
A customer Is setting up a two-node cluster to serve (SCSI LUNs. How many interfaces should be created?
正解：B
解説：
For a two-node cluster serving iSCSI LUNs, it is recommended to create two iSCSI LIFs per node. This configuration provides redundancy and load balancing, ensuring that each node can handle failover scenarios effectively and maintain high availability for the iSCSI connections.
For more details, see:
* NetApp Documentation on iSCSI LIF Configuration
質問 # 21
An administrator creates a new SVM for SAN connectivity on their two-node cluster. The customer needs a redundant configuration at the node layer and fabric layer.
How many LIFs, at minimum, should the administrator create for the SVM?
正解：D
解説：
For a redundant two-node FC SAN configuration, NetApp requires two FC LIFs per node when redundancy must exist across both the node and fabric layers. Each node should have connectivity to both independent fabrics, normally through one FC LIF per fabric. With two controller nodes, this results in four SAN LIFs in total. Although ONTAP can technically support a minimum of one FC LIF per node for an SVM, that would provide only two LIFs and would not satisfy the stated requirement for redundant node-layer and fabric-layer connectivity. NetApp ' s FC SVM configuration guidance specifically states that two LIFs per node and two fabrics provide this redundancy. Relevant SAN ONTAP topics include FC SVM configuration, SAN LIF design, dual-fabric architecture, multipathing, node redundancy, and high availability.
