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.
