The correct answer is A. Traffic is potentially dropped between the client and the destination. When SVI 10 is shut down on agg-sw1 (the VSX active gateway), traffic destined for the default gateway will not be able to use that SVI. Unless "VSX active forwarding" is enabled, the other VSX peer (agg-sw2) will not start forwarding traffic for that SVI, so packets are likely…
Question
Refer to the exhibit. After an initial setup of CX 8325 VSX configuration, the active gateway is set up for SVI 10. For testing purposes, SVI 10 on the sw-agg1 is shut down while traffic from the client connected to Edge-1 is initiated towards the default route. What is the expected behavior while performing this test?
Exhibit
Options
- ATraffic is potentially dropped between the client and the destination.
- BTraffic is forwarded over the ISL without the risk of dropped packets.
- CTraffic is unaffected and a 50ns failover time is expected for agg-sw2 to start traffic forwarding.
- DTraffic is dropped and vsx-sync will disable SVI10 on agg-sw2 automatically.

Explanation
When SVI 10 is shut down on agg-sw1 (the VSX active gateway), traffic destined for the default gateway will not be able to use that SVI. Unless "VSX active forwarding" is enabled, the other VSX peer (agg-sw2) will not start forwarding traffic for that SVI, so packets are likely dropped. The default failover is not seamless unless you enable active-forwarding or use a redundancy feature for SVI gateways.
