Question 3 of 48

Two connected VPC networks use different MTU values. A VM in the larger-MTU network sends large UDP packets with the DF bit set to a VM in the smaller-MTU network. Which design consideration is correct?

AGoogle Cloud fragments the packets automatically inside the VPC
BGoogle Cloud drops oversized packets and relies on PMTUD with ICMP or ICMPv6 feedback
CThe packets always pass because peered VPC traffic ignores MTU mismatches
DChanging only the sender VM NIC MTU above the VPC MTU avoids the problem
