   A BIG-IP administrator is reviewing the interface status page and sees that a trunk member interface is showing a status of 'up' but the 'Active' column shows 'No'. The trunk has four members, and the other three are showing 'Active: Yes'. The administrator notices that the interface with 'Active: No' is not receiving any traffic. What is the most likely reason for this state?

   • AThe interface has been administratively disabled from the trunk.
   • BThe trunk hashing algorithm is not selecting this interface for any current traffic flows.
   • CThe interface is not assigned to any VLAN.
   • DThe interface is experiencing errors and has been automatically excluded from the trunk.

   An administrator is configuring a new BIG-IP device and needs to connect it to a switch. The administrator wants to ensure that the interface is automatically configured for the highest possible speed and duplex. What should the administrator do?

   • ASet the interface to 10 Gbps full duplex to future-proof the connection.
   • BLeave the interface speed and duplex settings at their default 'auto' values.
   • CConfigure the interface as a trunk member to increase bandwidth.
   • DManually set the interface to 1 Gbps full duplex.

   An administrator is troubleshooting intermittent connectivity issues on a BIG-IP system. The interface connected to the upstream router shows a status of 'up' but the administrator observes frequent 'link down' and 'link up' events in the system log. The switch port and cable have been replaced, and the issue persists. What is the most likely cause of this flapping behavior?

   • AA duplex mismatch between the BIG-IP interface and the upstream router.
   • BThe interface is configured with a higher MTU than the router supports.
   • CThe interface is part of a trunk that is experiencing a failover event.
   • DThe VLAN assigned to the interface is not present on the upstream router.

   A BIG-IP administrator notices that a specific interface is showing 'up' but is experiencing a high rate of input errors on the interface counters. The administrator suspects a duplex mismatch. What should the administrator do to confirm this suspicion?

   • AVerify that the interface is a member of the correct trunk.
   • BCheck the VLAN configuration on the interface.
   • CReview the system logs for TMM error messages.
   • DCheck the negotiated speed and duplex settings on both the BIG-IP and the connected switch port.
