Refer to the exhibit.
Which three statements about the exhibit are true? (Choose three.)
A. The differentiating characteristic of the Cisco Nexus 1000V Series is that it does not run Spanning Tree Protocol. This characteristic may seem to be a significant departure from other Ethernet switches, which might potentially cause catastrophic network loops. However, in reality, the Cisco Nexus 1000V Series implements a simple and effective loop-prevention strategy that does not require Spanning Tree Protocol.
B. Because the Cisco Nexus 1000V Series does not participate in Spanning Tree Protocol, it does not respond to BPDU packets, nor does it generate them. BPDU packets that are received by Cisco Nexus 1000V Series Switches are dropped.
C. The Cisco Nexus 1000V Series uses a simple technique to prevent loops. Like a physical Ethernet switch, the Cisco Nexus 1000V Series Switch performs source and destination MAC address lookups to make forwarding decisions. The VEM applies loop-prevention logic to every incoming packet on Ethernet interfaces.
D. The Cisco Nexus 1000V Series uses a simple technique to prevent loops. Like any logical Ethernet switch, the Cisco Nexus 1000V Series Switch performs source and destination MAC address lookups to make forwarding decisions. The VEM applies loop-prevention logic to every incoming packet on Ethernet interfaces.
E. Because the Cisco Nexus 1000V Series participates in Spanning Tree Protocol, it responds to BPDU packets, and it generate them. BPDU packets that are received by Cisco Nexus 1000V Series Switches are dropped.
