Google Cloud Peering

Direct Peering

• Direct Peering establishes a direct peering connection between the on-premises network and Google’s edge network and exchanges high-throughput cloud traffic.
• Direct Peering provides a direct path from the on-premises network to Google services, including Google Cloud products that can be exposed through one or more public IP addresses.
• Traffic from Google’s network to the on-premises network also takes that direct path, including traffic from VPC networks in the projects.
• Google Cloud customers must request that direct egress pricing be enabled for each of the projects after they have established Direct Peering with Google
• Direct Peering exists outside of Google Cloud.
• Direct Peering doesn’t produce any custom routes in a VPC network
• Direct Peering does not provide any SLA
• Direct peering helps reduce Internet egress rates to on-premises network from GCP resources

Carrier Peering

• Carrier Peering helps access Google applications, such as Google Workspace, by using a service provider to obtain enterprise-grade network services that connect your infrastructure to Google.
• Carrier Peering exists outside of Google Cloud
• Carrier Peering doesn’t produce any custom routes in a VPC network
• Direct Peering does not provide any SLA

Peering Requirements

• Publicly routable ASN
• Publicly routable address space (at least one /24 of IPv4 and/or one /48 of IPv6 space)
• ASN record completed in PeeringDB
• 24×7 NOC contact
• Presence at one or more internet exchanges or private peering interconnection facilities listed for Google in PeeringDB
• Up to date Maintainer, ASN, AS-SET, and Route/Route6 objects in an internet routing registry (IRR) used by Google

GCP Certification Exam Practice Questions

• Questions are collected from Internet and the answers are marked as per my knowledge and understanding (which might differ with yours).
• GCP services are updated everyday and both the answers and questions might be outdated soon, so research accordingly.
• GCP exam questions are not updated to keep up the pace with GCP updates, so even if the underlying feature has changed the question might not be updated
• Open to further feedback, discussion and correction.
