GCP PCA · Question 40 · Domain 2: Managing and Provisioning a Solution Infrastructure

You need to connect your on-premises data center to Google Cloud. You are evaluating Cloud VPN and Cloud Interconnect. Which TWO statements are correct when comparing these services? (Select TWO)

Answer options:

A.

Cloud VPN provides a dedicated physical connection to Google's network.

B.

Dedicated Interconnect provides higher bandwidth and lower latency than Cloud VPN.

C.

Cloud VPN cannot be used for production workloads.

D.

Cloud Interconnect automatically encrypts all traffic using IPsec by default.

E.

Cloud VPN is generally faster to provision and set up than Dedicated Interconnect.

How to approach this question

Compare VPN (internet-based, fast setup, lower bandwidth) with Interconnect (physical link, slow setup, high bandwidth, low latency).

Full Answer

B,E
Cloud VPN uses IPsec to encrypt traffic over the public internet. It is fast to provision but subject to internet latency. Dedicated Interconnect is a physical connection between your on-prem network and Google's edge. It offers massive bandwidth (up to 100 Gbps) and consistent low latency, but takes time to physically provision. Note that Interconnect traffic is not encrypted by default.

Common mistakes

Assuming Interconnect is encrypted by default (D). Because it's a private physical link, GCP doesn't encrypt it by default. You must add encryption if compliance requires it.
