Google Cloud Router

• Cloud Router is a fully distributed and managed service that programs custom dynamic routes and scales with the network traffic.
• Cloud Router works with both legacy networks and VPC networks.
• Cloud Router isn’t a connectivity option, but a service that works over Cloud VPN or Interconnect connections to provide dynamic routing by using the Border Gateway Protocol (BGP) for the VPC networks.
• Cloud Router isn’t supported for Direct Peering or Carrier Peering connections.
• Cloud Router isn’t a physical device that might cause a bottleneck, and it can’t be used by itself.
• Cloud Router is required or recommended in the following cases:
  • Required for Cloud NAT
  • Required for Cloud Interconnect and HA VPN
  • A recommended configuration option for Classic VPN.
• Cloud Router helps dynamically exchange routes between the Google Cloud network and the on-premises network.
• Cloud Router peers with the on-premises VPN gateway or router to provide dynamic routing and exchanges topology information through BGP.
• Cloud Router frees you from maintaining static routes
• Google Cloud recommends creating two Cloud Routers in each region for a Cloud Interconnect for 99.99% availability.
• Cloud Router supports following dynamic routing mode
  • Regional routing mode – provides visibility to resources only in the defined region.
  • Global routing mode – provides visibility to resources in all regions

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• GCP services are updated everyday and both the answers and questions might be outdated soon, so research accordingly.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.
