Google Professional Cloud Network Engineer Exam - Topic 2 Question 90 Discussion

Actual exam question for Google's Professional Cloud Network Engineer exam

Question #: 90
Topic #: 2

[All Professional Cloud Network Engineer Questions]

You are increasing your usage of Cloud VPN between on-premises and GCP, and you want to support more traffic than a single tunnel can handle. You want to increase the available bandwidth using Cloud VPN.

What should you do?

ADouble the MTU on your on-premises VPN gateway from 1460 bytes to 2920 bytes.

BCreate two VPN tunnels on the same Cloud VPN gateway that point to the same destination VPN gateway IP address.

CAdd a second on-premises VPN gateway with a different public IP address. Create a second tunnel on the existing Cloud VPN gateway that forwards the same IP range, but points at the new on-premises gateway IP.

DAdd a second Cloud VPN gateway in a different region than the existing VPN gateway. Create a new tunnel on the second Cloud VPN gateway that forwards the same IP range, but points to the existing on-premises VPN gateway IP address.

D seems like overkill for just increasing bandwidth.

Wait, doubling the MTU? That sounds risky!

A definitely won't help with bandwidth, just saying.

I think C could work too, but not sure if it's necessary.

B is the way to go for more bandwidth!

I feel like option D could work too, especially if the second gateway is in a different region. It might help with redundancy as well.

I practiced a similar question where adding a second gateway was the solution. Option C sounds familiar, but I’m not completely confident.

I'm not entirely sure, but doubling the MTU seems risky. I think it could cause fragmentation issues.

I remember something about creating multiple tunnels to increase bandwidth, so maybe option B is the right choice?

Option B seems like the simplest approach - just create two tunnels pointing to the same on-premises gateway. That should give me the bandwidth boost I need without too much additional complexity.

Hmm, I'm a bit confused about the differences between the multiple tunnel options. I'll need to think through the implications of each one carefully before deciding.

This looks like a straightforward question about increasing bandwidth for a Cloud VPN connection. I think the key is to create multiple tunnels, so I'm leaning towards options B or C.

I'm not sure about doubling the MTU on the on-premises gateway. That could cause compatibility issues, so I'm hesitant to go with option A. The multiple tunnel approaches seem safer.

Hmm, I'm a bit unsure about this one. The options seem to cover a range of different activities, so I'll need to think carefully about which two are most appropriate for the first Sprint.

Ah, the age-old conundrum of bandwidth vs. complexity. Maybe we could just send the data through a wormhole instead?

Why don't we just duct tape the on-premises VPN gateway and call it a day? I'm sure that would work just as well!

Option D looks interesting, but I'm not sure if adding a second Cloud VPN gateway in a different region is really necessary for this use case. Might be overkill.

Option C seems like a good choice. Adding a second on-premises VPN gateway and creating a new tunnel on the existing Cloud VPN gateway could provide more flexibility and redundancy.

And creating a new tunnel on the existing Cloud VPN gateway would increase available bandwidth.

I think option B is the way to go. Creating two VPN tunnels on the same Cloud VPN gateway is a simple and effective solution to increase the available bandwidth.
