F5 Networks F5CAB2 Exam - Topic 5 Question 11 Discussion

A Traffic Group is a collection of related configuration objects that fail over together from one BIG-IP device to another. Only 'floating' objects can be members of a traffic group.

Virtual Addresses (C): A virtual address (the IP part of a Virtual Server) is a floating object. It is assigned to a traffic group so that the entire IP moves to the standby unit during a failover.

Floating Self IPs (E): These are used as gateways for backend servers or SNAT addresses. By associating them with a traffic group, they remain reachable by the backend network regardless of which BIG-IP is currently active.

Why other options are incorrect:

iRules (A): iRules are configuration logic files; they are synchronized across devices but are not 'hosted' by a traffic group.

VLANs (D): VLANs are local to the hardware interfaces/trunks of each specific device and do not fail over.
