seems that D Create Cloud Routers For Partner Interconnect, all Cloud Routers must have a local ASN of 16550. source: https://cloud.google.com/network-connectivity/docs/interconnect/tutorials/partner-creating-9999-availability

100% for sure, I did it last month

The correct answer is B. Use a 2-byte private ASN 64512-65535. Here's why: Private ASNs are used for internal networks and are not routable on the public internet. This is ideal for connecting your on-premises network to your Google Cloud VPC. Public ASNs are used for networks that are publicly routable. You wouldn't want to use a public ASN for your internal connection. Specifically, the recommended private ASN range for Cloud Router in this scenario is 64512-65535.

D is correct because for Partner Interconnect, all Cloud Routers must have a local ASN of 16550, which is a public Google ASN. Option D suggests using a public Google ASN of 16550, which is the correct approach. Options A and B suggest using private ASNs, which is not recommended. Option C suggests using a public Google ASN of 15169, which is not valid for Partner Interconnect.

• D. Use a public Google ASN ***** 16550. Create Cloud Routers Create two Cloud Routers, one in each region. For Partner Interconnect, all Cloud Routers must have a local ASN of 16550.

D is right

D is right Create two Cloud Routers, one in each region. For Partner Interconnect, all Cloud Routers must have a local ASN of 16550.

Yes D it is on GC side, B you can pick for the other end.
