Google Cloud Professional Cloud Network Engineer — Question 138

You have an HA VPN connection with two tunnels running in active/passive mode between your 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?

Answer options

• A. Configure the remote autonomous system number (ASN) to 4096.
• B. Configure a second Cloud Router to scale bandwidth in and out of the VPC.
• C. Configure the maximum transmission unit (MTU) to its highest supported value.
• D. Configure a second set of active/passive VPN tunnels.

Correct answer: D

Explanation

The correct answer is D because adding a second set of active/passive VPN tunnels will effectively double the available bandwidth, accommodating the increased traffic. Options A, B, and C do not directly address the need for additional bandwidth and would not resolve the packet loss issue caused by exceeding the current capacity.
