An administrator is unable to discover a Nutanix-hosted iSCSI block device allocated to a bare- metal host. What is causing this issue?

Question

Options

• AJumbo frames has not been configured on the switch
• BExternal client access has not been enabled for the host
• CNetwork segmentation has not been enabled
• DExternal host IP address is not in the Filesystem Whitelist

• A
  5% (2)
• B
  3% (1)
• C
  8% (3)
• D
  85% (33)

Explanation

When Nutanix Volumes (iSCSI) is used to present block storage to a bare-metal host, the host's IP address must be explicitly added to the whitelist (client access list) associated with the Volume Group. Without this, the iSCSI target will not respond to discovery requests from that host, making the block device invisible to the initiator. Option B ('External client access has not been enabled') is closely related but refers to a broader setting, while D specifically identifies that the host IP is absent from the whitelist - the precise configuration required for per-host access control. Option A (jumbo frames) affects performance but not discoverability. Option C (network segmentation) is a Flow feature unrelated to iSCSI target access.
