Free Google Professional Cloud Network Engineer Actual Exam Questions - Question 10 Discussion
Virtual Private Cloud (VPC) and on-premises network. Traffic over the connection has recently
increased from 1 gigabit per second (Gbps) to 4 Gbps, and you notice that packets are being dropped.
You need to configure your VPN connection to Google Cloud to support 4 Gbps. What should you do?
B/D? Adding another Cloud Router (B) might help manage routing better and support more tunnels, but the real bottleneck is usually the tunnel bandwidth itself. Since each tunnel maxes out around 1.5-2 Gbps, just adding routers won’t solve packet drops at 4 Gbps. So setting up a second active/passive pair of tunnels (D) would let you split the traffic across multiple tunnels, effectively scaling the VPN capacity. The MTU change (C) won’t increase bandwidth, and ASN (A) seems unrelated to throughput limits.
Maybe B works too since adding another Cloud Router can balance the load better, but that alone might not fix the tunnel bandwidth limit. Still, it’s a solid way to handle more overall traffic from the VPC side.
It’s D because each tunnel caps around 1.5-2 Gbps, so adding another set of tunnels is the practical way to boost total throughput beyond 4 Gbps. Just increasing router capacity won’t help alone.
Maybe B makes sense to handle more traffic by scaling Cloud Router capacity.
It’s D, adding a second tunnel set increases capacity.
