Cloud VPN securely connects your peer enterprise network to your Google Cloud Virtual Private Cloud network through an encrypted IPsec connection over the public internet. This connection type allows internal resources to communicate securely across environments without exposing data traffic to external interception threats. Cloud VPN tunnels establish rapid, reliable communication links that support hybrid cloud architecture strategies seamlessly. Network administrators can deploy high-availability VPN configurations with dynamic routing features using BGP to ensure uninterrupted connectivity during routine maintenance or unexpected link disruptions effectively.

Question 128

Which service enforces Zero Trust access to internal apps?

1. Cloud Armor
2. Identity-Aware Proxy
3. VPC Service Controls
4. Cloud NAT

Correct Answer: 2

Explanation

Identity-Aware Proxy protects web applications by verifying user identity and device security posture before granting access to internal corporate tools. Instead of relying on traditional perimeter-based security or corporate VPNs, IAP establishes an application-level access control layer. It evaluates context parameters such as user credentials, group memberships, and endpoint security compliance dynamically for every incoming request. If an access attempt meets security policies, IAP permits connection; otherwise, it blocks unauthorized traffic. This Zero Trust security architecture significantly reduces the corporate attack surface and prevents lateral movement threats.

Question 129

Which tool provides automated optimization recommendations?

1. Cloud Monitoring
2. Cost Table
3. Recommender
