A BIG-IP Administrator needs to have a BIG-IP linked to two upstream switches for resilience of the external network. The network engineer who is going to configure the switch instructs the BIG-IP Administrator to configure interface binding with LACP. Which configuration should the administrator use? (Choose one answer)

A. A virtual server with an LACP profile and the switches’ management IPs as pool members.
B. A virtual server with an LACP profile and the interfaces connected to the switches as pool members.
C. A Trunk listing the allowed VLAN IDs and MAC addresses configured on the switches.
D. A Trunk containing an interface connected to each switch.

Based on the requirement to connect a BIG-IP device to two upstream switches for external network resilience and the instruction to use Link Aggregation Control Protocol (LACP) for interface binding, the correct configuration is to create a trunk that aggregates the interfaces connected to those switches.
D. A Trunk containing an interface connected to each switch.
LACP (Link Aggregation Control Protocol - IEEE 802.3ad): This protocol allows the BIG-IP to combine multiple physical ports into a single logical link (Trunk/LAG) to increase bandwidth and provide redundancy.
Resilience (Two Upstream Switches): To connect to two different switches, those switches must be configured with a technology like Virtual Port Channel (vPC) or Multichassis Link Aggregation (MLAG/mLACP) to appear as a single logical peer to the BIG-IP.
Configuration: The administrator should navigate to Network > Trunks, create a new trunk, add the interfaces connected to the upstream switches, and enable LACP.
