[All Professional Cloud Network Engineer Questions]

You are deploying your infrastructure in the us-central1 region. Your on-premises data center is located in New York City, and the Google Cloud region closest to New York City is us-east4. Your Cloud Interconnect is located in Ashburn, Virginia (VA), United States. You need to use Cloud Interconnect to connect your application infrastructure with backend systems in your data center location. You do not expect the application bandwidth to exceed 500 Mbps. You want to minimize latency and cost. What should you do?

A. Create a Cloud Router and VLAN attachments in the us-east4 region attached to your physical Interconnect in Ashburn, VEnable global routing in your VPC. Set the bandwidth on the VLAN attachments to 500 Mbps.
B. Create a Cloud Router and VLAN attachments in the us-east4 region attached to your physical Interconnect in Ashburn, VA. Enable global routing in your VPC.
C. Create a Cloud Router in the us-central1 region and VLAN attachments in the us-east4 region attached to your physical Interconnect in Ashburn, VA. Enable global routing in your VPC.
D. Create a Cloud Router and VLAN attachments in the us-central1 region attached to your physical Interconnect in Ashburn, VA.

Selected Answer: B

A) Setting bandwidth is not the required configuration step to enable routing between regions. Also, specifying 500 Mbps adds no real value unless you're configuring a Partner Interconnect with a specific provisioning model — and even then, this can be adjusted later. C) Incorrect because the Cloud Router must be in the same region as the VLAN attachments — you cannot create a Cloud Router in us-central1 and attach it to a VLAN in us-east4. D) Also incorrect because Ashburn is in us-east4, and placing the Cloud Router and VLAN in us-central1 won’t work — you must create them in the same region as the Interconnect.

Selected Answer: B

Option B is correct option A: explanation why B is better answer then A. It is mostly correct but unnecessarily mentions setting the VLAN bandwidth explicitly in the answer. This does not change the network design or impact latency/cost significantly.
