   A company is deploying a BIG-IP device in a data center to handle traffic for a high-volume web application. The network team wants to increase the available bandwidth between the BIG-IP and the upstream switch, and they also want to provide redundancy in case a physical link fails. They have four 1 Gbps interfaces available on the BIG-IP and four corresponding ports on the switch. The switch supports 802.3ad link aggregation. What should the administrator configure on the BIG-IP to meet these requirements?

   • AAssign each interface to a separate VLAN and use policy-based routing to load-balance traffic.
   • BConfigure a self-IP on each interface and rely on ECMP routing to distribute traffic.
   • CUse a single interface and increase the MTU to improve throughput.
   • DCreate a trunk with the four interfaces as members and enable LACP.

   When a VLAN is associated with a trunk, how is untagged traffic handled?

   • AUntagged traffic is dropped by the trunk
   • BUntagged traffic is distributed across all VLANs associated with the trunk
   • CUntagged traffic is automatically tagged with the first VLAN ID in the trunk
   • DUntagged traffic is assigned to the VLAN that is configured as untagged on the trunk

   A company is deploying a BIG-IP device in a high-availability pair. They have a limited number of interfaces available: two 10 Gbps interfaces for the external network and two 10 Gbps interfaces for the internal network. The network team wants to maximize bandwidth and redundancy for both networks. The switch supports LACP. What is the best configuration to achieve this?

   • ACreate a single trunk with all four interfaces and assign it to both external and internal VLANs.
   • BUse one interface for external and one for internal, and keep the other two as spare.
   • CCreate two trunks: one with the two external interfaces and one with the two internal interfaces, both with LACP enabled.
   • DCreate a trunk with the two external interfaces and use the internal interfaces as separate untagged interfaces.

   A BIG-IP administrator is monitoring a trunk and notices that the traffic distribution is uneven across the member interfaces. One interface is carrying significantly more traffic than the others. What is the most likely cause of this imbalance?

   • AThe trunk's distribution algorithm is not suitable for the traffic pattern.
   • BOne of the member interfaces is down.
   • CThe LACP mode is set to passive.
   • DThe trunk is not associated with any VLAN.

   A BIG-IP administrator is monitoring a trunk and notices that the trunk status is 'up', but the traffic is not passing through the trunk as expected. The trunk is associated with a VLAN, and the self-IP is configured. What should the administrator check next?

   • ACheck the LACP mode on the switch.
   • BVerify that the VLAN is correctly associated with the trunk and that the trunk is a member of the VLAN.
   • CReboot the BIG-IP device.
   • DCheck the routing table to see if the self-IP is reachable.
