In the exhibit, a chassis cluster is deployed in active/active mode. This chassis cluster control and fabric links are connected through 100 Mbps WAN connections. During peak data usage times the chassis cluster becomes disabled even though the rate of new connections through the cluster is relatively low.
What is the problem?
A.
Control and fabric link WAN connections are not supported through a non-Ethernet-based technology. VPLS must be used instead
B.
Control link heartbeats are being lost during peak data usage times. The WAN connection that supports the control link must be upgraded to support greater bandwidth.
C.
Fabric link probes are being lost during peak data usage times. The WAN connection that supports the fabric link must be upgraded to support greater bandwidth
D.
Latency across a WAN connection will always exceed the recommended 100 ms limit. The chassis cluster will always enter the disabled state during peak data usage.
