Question 46 Discussion

The network architecture for a BIG-IP consists of an external and internal VLAN with two interfaces connected to the upstream switch. The design requires fault tolerance in the case that one of the interfaces is down. Which deployment architecture meets these requirements? (Choose one answer)

  • A. One network trunk with both VLANs and LACP enabled, and both VLANs configured as untagged
  • B. Two network trunks each with one VLAN and LACP enabled, and both VLANs configured as tagged
  • C. Two network trunks each with one VLAN and LACP disabled, and one VLAN configured as tagged and one VLAN configured as untagged
  • D. One network trunk with both VLANs and LACP enabled, and both VLANs configured as tagged

Using a single LACP trunk with both VLANs tagged ensures link redundancy and proper VLAN separation across both interfaces.

A Self IP in BIG-IP is an IP address assigned to the device itself on a particular network segment, which allows the BIG-IP to communicate with other devices (nodes, pools, gateways) on that network.

When you configure a Self IP, you must specify where it “lives” physically or logically on the device. That is done by associating it with a VLAN or a Trunk.

A. Interface ❌ – You don’t assign a Self IP directly to a physical interface. Interfaces can be part of a VLAN or a Trunk, and the Self IP attaches to that logical grouping.

B. Route ❌ – Routes define where traffic goes, not where the IP resides.

C. Trunk ❌ – A Self IP can be on a Trunk, but only indirectly. You actually assign the Self IP to a VLAN, and the VLAN may use a Trunk underneath.

D. VLAN ✅ – Correct.

When configuring a Self IP, you must assign it to a VLAN (or an interface indirectly through VLAN/Trunk).

✅ Correct Answer:

D. VLAN

Tip to remember:

“Self IP → VLAN. VLAN may use an Interface or Trunk underneath, but the Self IP always attaches to the VLAN.”
