A company has combined multiple Web servers into one AIX LPAR with a single physical network connection. How can AIX be configured with multiple IP addresses on the same physical connection?

Question

Accepted Answer

C. Add the additional IP addresses as aliases to the network connection. AIX allows IP aliasing on a network adapter such as en0 so that multiple IP addresses share the same physical connection. This is configured via 'ifconfig en0 alias ' or through SMIT, and each alias binds an additional address to the same physical adapter without requiring additional hardware.

Answer

A. Add the additional IP addresses as aliases in DNS. Adding aliases in DNS only affects name resolution and does not assign IP addresses to the actual network interface, so inbound traffic would not reach the adapter correctly.

Answer

B. Add the IP addresses to the primary hostname line in /etc/hosts. The /etc/hosts file provides static hostname-to-IP mappings for local lookup only and has no effect on which IP addresses are actually configured on network interfaces.

Answer

D. Assign the IP addresses to virtual Ethernet adapters and map them to the physical network connection. Virtual Ethernet adapters are used in AIX VIO Server environments to share physical adapters across LPARs, which is unrelated to assigning multiple IPs on a single adapter in a non-virtualized single-LPAR context.
