A BIG-IP administrator is troubleshooting a trunk that is experiencing intermittent packet loss. The trunk has four member interfaces, and the trunk status shows 'up'. The administrator suspects that one of the member interfaces is flapping. What is the best way to confirm this?

Monitor the trunk statistics over time to see if the traffic distribution changes and if any member shows a high error rate.

Restart the BIG-IP device to clear any temporary issues.

Replace all the network cables connected to the trunk.

Check the routing table to see if the trunk's self-IP is still reachable.

A BIG-IP device is configured with a trunk that carries VLAN 100 (untagged) and VLAN 200 (tagged). The administrator notices that traffic from VLAN 200 is not being processed correctly. What is the most likely cause of this issue?

The trunk is not configured to allow tagged traffic for VLAN 200.

The trunk's LACP mode is set to passive.

The trunk is set to untagged for both VLANs.

The trunk's media type is incorrect.

Which benefit does a BIG-IP trunk provide beyond what a single physical interface can offer?

It increases the maximum throughput beyond the capacity of one interface

It enables the BIG-IP to route between VLANs without a default gateway

It allows multiple VLANs to share the same physical cable

It provides a separate management plane for administrative access

A BIG-IP administrator notices that a trunk on the device is showing degraded performance. The trunk has four member interfaces, and the administrator suspects that one of the links is not functioning correctly. What is the most direct way to verify the status of each member interface in the trunk?

Check the trunk statistics in the BIG-IP configuration utility to see the traffic distribution across each member.

Examine the VLAN configuration to ensure the trunk is assigned to the correct VLANs.

Review the routing table to see if the trunk's self-IP is reachable.

Run a packet capture on the trunk interface to analyze traffic patterns.
