Network Appliance Implementation Engineer - SAN ONTAP Exam 認定 NS0-521 試験問題 (Q25-Q30):

質問 # 25
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. Configure CHAP authentication.
  • B. Map the LUNs to the igroup.
  • C. Create an igroup with the ESXi hosts' WWNNs.
  • D. Create an igroup with the ESXi hosts' WWPNs.

正解:B、D

解説:
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

質問 # 26
A storage administrator recently implemented ISCSI SAN in a customer environment. Which two actions should be done to ensure the best performance? (Choose two.)

  • A. Configure Jumbo frames In the entire data path.
  • B. Connect host and storage ports to the same switches.
  • C. Decrease the default queue depth on the host to eight.
  • D. Zone the host by using the host WWPNs.

正解:A、B

解説:
To ensure the best performance in an iSCSI SAN implementation:
* Connect host and storage ports to the same switches: This minimizes latency and maximizes the efficiency of data paths by ensuring direct connections within the same network segment.
* Configure Jumbo frames in the entire data path: Setting a larger Maximum Transmission Unit (MTU) size reduces the overhead for processing each packet, thus improving overall network performance. Ensuring Jumbo frames are configured end-to-end in the data path is crucial for optimal
* performance.
For further details, check:
* NetApp Best Practices for iSCSI
* NetApp Community Discussion on iSCSI Performance

質問 # 27
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. vserver iscsi security create
  • B. security login create
  • C. igroup initiator modify
  • D. security certificate create

正解:A

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 # 28
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. Broadcast domain.
  • C. Access list
  • D. Network route

正解:C

解説:
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.
For additional details, you can refer to:
* NetApp SAN Administration Guide

質問 # 29
What Is modified when moving a LUN between different HA pairs in the same SVM to prevent loss of connectivity?

  • A. reporting nodes
    Cigroup
  • B. port name
  • C. LUN mapping

正解:A

解説:
When moving a LUN between different HA pairs in the same SVM to prevent loss of connectivity, the reporting nodes must be modified. The reporting nodes configuration ensures that the initiator paths are properly updated to reflect the new physical location of the LUN. This prevents disruptions in connectivity by maintaining the correct pathing information for the host systems accessing the LUN.
For more details, refer to:
* NetApp Documentation on LUN Management
