The correct answer is D. Cisco distribution switches send untagged standard BPDUs to HP switch in VLAN 1, which the HP switch forwards to the other distribution switch, preventing a loop. The HP switch drops all tagged data frames. See the full explanation below for the reasoning.
Question
You want to add HP edge switches to a company's Cisco network. Distribution Cisco switches are set as the Rapid PVST+ root and secondary root. You connect HP A-Series switches that are running their factory default configuration to the two Cisco distribution switches. What will happen?
Options
- AIf you connect the edge-switch with a redundant link to both distribution switches, you create a loop and a broadcast storm on the Cisco network.
- BCisco distribution switches send tagged PVST+ BPDUs to the HP switch. Because 802.1q is not yet configured on HP switch uplinks, the PVST+ BPDUs are dropped. A loop occurs.
- CCisco distribution switches send untagged standard BPDUs to the HP switch in VLAN 1, and in response the HP switch blocks one of the uplinks on all VLANs, preventing a loop.
- DCisco distribution switches send untagged standard BPDUs to HP switch in VLAN 1, which the HP switch forwards to the other distribution switch, preventing a loop. The HP switch drops all tagged data frames.
