Which NICs are present on a physical Infoblox appliance?

• A. IPMI, LAN1, LAN2, MGMT, HA
• B. IPMI, LAN1, LAN2, MGMT
• C. IPMI, LAN1, MGMT, HA
• D. LAN1, LAN2, MGMT, HA

Answer: (A)

Understand that a physical Infoblox appliance exposes five NICs: IPMI for out-of-band chassis management, LAN1 and LAN2 as the primary data networks, MGMT as a dedicated management network, and an HA interface used for high-availability communication between nodes. The best answer includes all of them because each NIC serves a distinct role essential to managing, operating, and keeping the appliance reliable in an HA deployment. If any one of these is missing, you’d lose an important capability: IPMI lets you manage the device even if the OS is down, LAN1/LAN2 provide the main network paths, MGMT gives a separate management channel, and HA supports heartbeat and coordination between appliances.
