ABlocks Tx unicast, allows Rx unicast, blocks Tx BUM, allows Rx BUM

BAllows Tx unicast, allows Rx unicast, blocks Tx BUM, allows Rx BUM

CBlocks Tx unicast, blocks Rx unicast, blocks Tx BUM, blocks Rx BUM

DAllows Tx unicast, blocks Rx unicast, allows Tx BUM, blocks Rx BUM

Show Answer

Correct Answer: A

A non-designated forwarder (non-DF) in a single-active Ethernet segment blocks Tx unicast, allows Rx unicast, blocks Tx BUM, and allows Rx BUM. This prevents traffic duplication and ensures that only the DF forwards traffic to and from the CE.

Question No. 2

In the exhibit, VPWS 4 enables communications between CEI and CE2. Which of the following statements regarding the operation of VPWS 4 is FALSE?
