Google Professional Cloud Network Engineer Exam - Topic 2 Question 15 Discussion

Actual exam question for Google's Professional Cloud Network Engineer exam
Question #: 15
Topic #: 2
[All Professional Cloud Network Engineer Questions]

Your software team is developing an on-premises web application that requires direct connectivity to Compute Engine Instances in GCP using the RFC 1918 address space. You want to choose a connectivity solution from your on-premises environment to GCP, given these specifications:

Your ISP is a Google Partner Interconnect provider.

Your on-premises VPN device's internet uplink and downlink speeds are 10 Gbps.

A test VPN connection between your on-premises gateway and GCP is performing at a maximum speed of 500 Mbps due to packet losses.

Most of the data transfer will be from GCP to the on-premises environment.

The application can burst up to 1.5 Gbps during peak transfers over the Interconnect.

Cost and the complexity of the solution should be minimal.

How should you provision the connectivity solution?

Show Suggested Answer Hide Answer
Suggested Answer: A

Direct Interconnect will be too expensive and also an overkill for this requirement. Managing multiple tunnels that too with packet loss consideration is complex also. Whereas partner interconnect fits the bill with providing required bandwidth but not super expensive also once setup not too complex too manage.

Network compression? Not sure that will solve the speed issue.

Multiple VPN tunnels could help with those packet losses.

Surprised that the VPN speed is only 500 Mbps, that's pretty low!

I disagree, Dedicated Interconnect could offer better performance.

Partner Interconnect seems like the best option here.

Network compression sounds interesting, but I wonder if it would really help with the speed limitations we’re facing right now.

I feel like the Dedicated Interconnect option might be overkill for our needs, especially since cost is a concern.

I'm not entirely sure, but I think using multiple VPN tunnels could help with the packet loss issue we saw in the test connection.

I remember studying about Partner Interconnect and how it can provide better performance than a VPN, especially with our ISP being a Google Partner.

Hmm, I'm not too sure about this one. I'll need to think it through a bit more. Maybe I can eliminate some of the options first.

I'm pretty sure the answer is C. The Windows universal forwarder should only be able to send logs to a Windows platform Splunk indexer, right?

I'm not totally sure, but I'm leaning towards Fibonacci estimation. That sounds like the right technique for this scenario.

I'm pretty sure the final step is Implementation, since that's when the contingency plan is actually put into action.

This looks like a tricky depreciation and tax question. I'll need to carefully work through the calculations to determine the net cash investment.

I've got this! It's a traditional browser-based application, since it's not designed to work well on mobile devices.
