You are troubleshooting an issue which is causing full-sized packets entering the MPLS cloud be dropped. You have discovered that one of the switches in the MPLS core is not a Cisco switch, but otherwise the MPLS MTU size is set to 1508 bytes on the routers.Based on this information, which of these may be the reason the packets are being dropped?（）

A. The switch on you MPLS core that was not produced by Cisco does not support oversized packets

B. No switches support oversized packets

C. By definition, the maximum MTU is 1500 bytes

D. As MPLS VPN labeling increases the size of the packet by 8 bytes, the IP MTU should have been changed to 1508
