問題文
Two aggregation switches are configured as a vPC pair, and a server below them is cabled to both. What does this arrangement achieve for the server?
選択肢
- The two switches elect one of themselves to answer, and the server forwards over one uplink while the other waits as a spare.
- The two switches present themselves to the server as one partner, and the server can therefore use both of its uplinks at the same time.
- The two switches share one forwarding table and one control process, and the server sees one device with twice the number of ports.
- The two switches synchronize their entire configuration with each other, and the server can be moved to either switch without any change to its uplinks.
