Networking in Google Cloud: Hybrid Connectivity & Network Management 

Q1. What is the purpose of a Cloud Router and why does that matter?

• It implements a dynamic VPN that allows topology to be discovered and shared automatically, which reduces manual static route maintenance.
• It connects VPN on one side to Direct Peering on the other, which is faster than VPN alone.
• A Cloud Router enables you to perform round-robin switching over multiple VPNs so that you can combine the bandwidth and get better throughput than is actually offered by the Internet.
• It is a hardware router, provided by Google but hosted in GCP.

Q2. Which GCP Interconnect service requires a connection in a GCP colocation facility and provides 10 Gbps per link?

• Carrier Peering
• Dedicated Interconnect
• Direct Peering
• Cloud VPN
• Partner Interconnect

Q3. If you cannot meet Google’s peering requirements, which network connection service should you choose to connect to Google Workspace and YouTube?

• Dedicated Interconnect
• Partner Interconnect
• Direct Peering
• Carrier Peering

Networking Pricing and Billing

Q1. Which of the following GCP network traffic types incurs a charge?

• Egress to the same zone through internal IP addresses

• Ensures that one resource is created before another
• Allows you to hard-code properties for your resources

Q3. What does Google Cloud Platform Marketplace offer?
