[All Professional Cloud Network Engineer Questions]

You have configured a service on Google Cloud that connects to an on-premises service via a Dedicated Interconnect. Users are reporting recent connectivity issues. You need to determine whether the traffic is being dropped because of firewall rules or a routing decision. What should you do?

AUse the Network Intelligence Center Connectivity Tests to test the connectivity between the VPC and the on-premises network.

BUse Network Intelligence Center Network Topology to check the traffic flow, and replay the traffic from the time period when the connectivity issue occurred.

CConfigure VPC Flow Logs. Review the logs by filtering on the source and destination.

DConfigure a Compute Engine instance on the same VPC as the service running on Google Cloud to run a traceroute targeted at the on-premises service.

Wait, can we really use Connectivity Tests for this? Sounds too easy!

D seems a bit overkill for this situation, right?

I remember doing a traceroute in a lab exercise, and it seemed helpful for diagnosing routing issues. But I’m not sure if it’s the best option here compared to the others.

I recall that VPC Flow Logs can be useful for troubleshooting, but I wonder if they would give enough detail to pinpoint the issue. It might take some time to sift through the logs.

I'm not entirely sure, but I feel like checking the Network Topology might help visualize where the traffic is going. It seems like a logical step to understand the flow.

I think using the Network Intelligence Center Connectivity Tests could be a good start to check if the connection is actually working. I remember it being mentioned in a practice scenario.

I think the best approach here is to set up a Compute Engine instance on the same VPC as the service and run a traceroute to the on-premises service. That should give me a clear view of the network path and any potential routing issues.

Hmm, I'm not sure which option to go with here. I might try configuring VPC Flow Logs and reviewing the logs to see if I can spot any issues with the traffic.

This looks like a tricky one. I think I'll start by using the Network Intelligence Center Connectivity Tests to check the connection between the VPC and the on-premises network.

Okay, I've got a plan. I'll use the Network Intelligence Center Network Topology to check the traffic flow and replay the traffic from the time the issue occurred. That should help me pinpoint where the problem is.

The key thing for a DWDM light source is maintaining a stable output wavelength, so I'm confident that A is the correct answer here.

I've got a good feeling about the USD 5 trillion per day option. That sounds about right for the scale of the global forex market. I'll go with that unless I can think of a compelling reason to choose something else.

Hmm, this seems like a straightforward question about where to verify the status of a specific link on a BIG-IP device. I'll need to think through the different configuration areas to determine the best place to look.

I can't remember if we generally negotiate risk transfers for medium likelihood ones. That sounds risky enough to negotiate, but is it worth it?
