Which two technologies enable multilayer segmentation?

B (Segment Routing): Allows traffic engineering and micro-segmentation across networks by steering traffic based on policies and labels.

D (Firewalls): Provide Layer 4-7 segmentation and security enforcement between segments.

Why other options are incorrect:

A: Policy-based routing influences forwarding, but is not a segmentation technology.

C: Data plane markings support QoS but do not create segmentation boundaries.

E: Filter lists are used in routing policy, not for full network segmentation.
