Practice Test 1 | Google Cloud Certified Professional Cloud Network Engineer | Dumps | Mock Test
A company has its on-premises network connected to its Google Cloud network using Dedicated Interconnect. One of the engineers noticed the VM’s in the GCP VPC could not be reached from the on-premises network. You have been called to troubleshoot the connectivity issue.
Which of the following steps should you take?
A. Check that your Border Gateway Protocol (BGP) session is active
B. Set the MTU size to 2000 on the on-premises router
C. Ensure there are overlaps between the routes advertised by your on-premises router and the Google Cloud network ranges
D. Confirm that your on-premises device is advertising and receiving routes
E. Confirm the VMs have monitoring agent installed in them
Correct Answers: A and D
- Option A is correct. Dedicated Interconnect uses BGP, so checking the BGP session is a valid step in troubleshooting the issue.
- Option B is incorrect. The correct MTU size to be specified is either 1440 or 1500.
- Option C is incorrect. There should be no overlaps between your on-premises route advertisements and Google Cloud network ranges.
- Option D is correct. Confirming that the on-premises route is advertising and receiving routes is a key step. This indicates that the Cloud Router and on-premises router know how to reach each other.
- Option E is incorrect. Monitoring agents have no impact on the hybrid connectivity between the networks.
