Listeners that correspond to nonfloating self lP addresses are stored in which configuration file?
The correct answer is D. /config/BIG-IP_local.conf. On BIG-IP, non-floating self IP addresses and their associated listeners are stored in /config/BIG-IP_local.conf, which holds node-specific configuration that is not synchronized across a device group.

Why each option
On BIG-IP, non-floating self IP addresses and their associated listeners are stored in /config/BIG-IP_local.conf, which holds node-specific configuration that is not synchronized across a device group.
/config/BIG-IP.conf holds the main shared configuration such as virtual servers, pools, and profiles, not node-specific non-floating self IP listeners.
/config/BIG-IP_base.conf stores base-level network settings like VLANs and the management interface configuration, not listener entries for non-floating self IPs.
/config/gtm/wideip.conf is specific to GTM wide IP objects such as wide IPs and pools, not BIG-IP listener or self IP configuration.
The file /config/BIG-IP_local.conf is reserved for configuration specific to the local node and is not synchronized to peer devices in a device group. Non-floating self IP addresses belong to individual nodes rather than the cluster, so their associated listeners are stored here to prevent them from being pushed to other devices.
