GCP ACE · Question 18 · Domain 2.4: Planning and configuring network resources

Your enterprise needs to connect its on-premises data center to a Google Cloud VPC. The connection must support a guaranteed bandwidth of 10 Gbps and must not traverse the public internet for security reasons.

Which TWO statements about fulfilling this requirement are correct? (Select TWO)

Answer options:

A.

You should use HA VPN with multiple tunnels to achieve 10 Gbps.

B.

You should use Dedicated Interconnect.

C.

Cloud VPN cannot be used because it traverses the public internet.

D.

You should use Partner Interconnect to get a direct 10 Gbps line from Google.

E.

You must configure Cloud NAT to allow the on-premises servers to reach the VPC.

How to approach this question

Identify the hybrid connectivity option that provides high bandwidth (10 Gbps) and avoids the public internet.

Full Answer

You should use Dedicated Interconnect., Cloud VPN cannot be used because it traverses the public internet.
Dedicated Interconnect provides direct physical connections between your on-premises network and Google's network. It does not traverse the public internet and is available in 10 Gbps or 100 Gbps capacities. Cloud VPN cannot be used because, although encrypted, the traffic travels over the public internet.

Common mistakes

Thinking HA VPN is sufficient because it can scale bandwidth, while ignoring the 'must not traverse public internet' constraint.
