Recall & Review

beginner

What is Cloud VPN in Google Cloud?

Cloud VPN is a service that securely connects your on-premises network to your Google Cloud Virtual Private Cloud (VPC) network using an encrypted tunnel over the public internet.

beginner

Why use Cloud VPN for hybrid connectivity?

Cloud VPN allows secure communication between your local data center and cloud resources, enabling a hybrid cloud setup where workloads can communicate safely across environments.

intermediate

What are the two main types of Cloud VPN in GCP?

The two types are Classic VPN and HA VPN. Classic VPN supports single tunnels, while HA VPN provides high availability with multiple tunnels and automatic failover.

intermediate

What is the role of IKE in Cloud VPN?

IKE (Internet Key Exchange) is a protocol used to set up a secure, authenticated communication channel between the two VPN endpoints before data is sent.

beginner

How does Cloud VPN ensure data security over the internet?

Cloud VPN encrypts data packets using IPsec protocols, which protect data confidentiality and integrity while it travels over the public internet.

What does Cloud VPN connect?

A Two on-premises data centers only

B Two Google Cloud projects only

C Your on-premises network to Google Cloud VPC

D Google Cloud to public internet without encryption

Cloud VPN securely connects your on-premises network to your Google Cloud VPC network.

Which Cloud VPN type offers high availability with automatic failover?

A HA VPN

C OpenVPN

D SSL VPN

HA VPN provides high availability with multiple tunnels and automatic failover.

What protocol does Cloud VPN use to encrypt data?

A HTTP

B IPsec

C FTP

D SMTP
