Which technology does the use of bi-directional BPDUs on all ports in the topology support?
A & B is a stupid option, bridge assurance runs in RSTP or MST
A quick summary of the features:
UDLD – Uni-Directional Link Detection puts unidirectional links into blocking state and prevents forwarding loops.
BPDU Guard – disables ports that receive a BPDU frame; useful for edge ports that should never be connected to another switch.
Loop Guard – Protects against ports where the link becomes unidirectional. It operates differently than the UDLD function.
Root Guard – Prevents a port from becoming a root port or a blocked port.
EtherChannel Guard – Prevents inconsistent configuration of EtherChannel that creates loops between two switches.
Bridge Priority – Defines the root bridge in an STP domain.
