An enterprise organization is scaling hybrid connectivity between its on-premises data center and a Google Cloud Virtual Private Cloud (VPC) network. The current throughput requirements exceed the capacity of a single High Availability (HA) VPN gateway (250,000 packets per second per tunnel). The network security team must design an expanded VPN architecture that meets the following criteria: Increases aggregate bandwidth by utilizing multiple HA VPN gateways Ensures automatic failover and maintains the 99.99% availability Service Level Agreement (SLA) Avoids severe bandwidth throttling or asymmetric traffic degradation during a partial tunnel failure Which architectural design should the team implement?

Deploy multiple HA VPN gateways configured in an active/active routing topology across all gateways, advertise identical prefixes with equal BGP MED values across all active tunnels, and match the corresponding gateway interfaces.: What an Active/Active Multi-Gateway HA VPN Architecture Is An active/active multi-gateway HA VPN architecture connects multiple Google Cloud HA VPN gateways to redundant on-premises peer VPN appliances. By configuring each tunnel pair in an active/active dynamic routing configuration over BGP with equal Multi-Exit Discriminator (MED) base priorities, Google Cloud distributes traffic across all active tunnels using Equal-Cost Multi-Path (ECMP) hashing. How It Meets the Requirements Scales aggregate bandwidth: Adding multiple HA VPN gateways and tunnel pairs overcomes the single-tunnel throughput limit of 250,000 packets per second, aggregating capacity across all established active paths. Maintains 99.99% availability SLA: The architecture satisfies Google Cloud SLA topology requirements by properly matching physical/logical interfaces across HA VPN gateways and peer devices. Prevents bandwidth degradation on partial failure: In an active/active configuration across multiple gateways, if a single tunnel fails, BGP withdraws that specific path while traffic immediately re-balances across the remaining healthy active tunnels without waiting for total gateway failure. Key Advantages and Capabilities ECMP load distribution: Dynamically shares traffic across multiple interfaces and tunnels simultaneously. Deterministic failover: Leverages dynamic BGP and optional Bidirectional Forwarding Detection (BFD) to detect tunnel breakage and withdraw failed next-hop routes in sub-minute intervals. Horizontal scalability: Allows incremental addition of HA VPN gateway pairs to scale throughput linearly as workload demands grow. High availability SLA adherence: Guarantees Google Cloud 99.99% uptime compliance by maintaining interface parity. Why This Is Optimal Unlike multi-gateway active/passive configurations—which suffer from failover deadlocks where standby tunnels remain unused until all active tunnels across all gateways fail—an active/active setup across multiple gateways ensures all provisioned bandwidth is actively utilized while maintaining graceful degradation during link failures.

An enterprise organization is deploying High Availability (HA) VPN over Cloud Interconnect to meet strict compliance mandates for data-in-transit encryption between its on-premises data center and a Google Cloud VPC network. The underlying Dedicated Interconnect connection is fully operational, and the BGP session for the Interconnect Cloud Router is established. However, the HA VPN tunnels fail to establish (IKE negotiation fails), and the on-premises VPN device cannot reach or detect the Google Cloud HA VPN gateway endpoints. Which action should the security engineer take to resolve this issue?

Designing and configuring private connectivity and encryption between data centers and VPC network (e.g., HA VPN, Cloud Interconnect).

A financial enterprise requires a secure, high-bandwidth connection between its on-premises data center and a Google Cloud VPC network. Compliance regulations mandate that all data in transit must be encrypted using IPsec tunnels, and the architecture must guarantee a 99.99% availability Service Level Agreement (SLA) with automated dynamic route propagation via BGP. Which configuration should the network security engineer implement to satisfy these requirements?

Designing and configuring private connectivity and encryption between data centers and VPC network (e.g., HA VPN, Cloud Interconnect).

An enterprise hosts an e-commerce platform behind an external Application Load Balancer with an attached Google Cloud Armor security policy. The security engineering team has the following access and threat protection requirements for a backend service: Allow corporate administrators connecting from the CIDR range 198.51.100.0/24 to access administrative endpoints matching request.path.matches('/admin/.') without being blocked by general WAF inspection. Block all other external clients attempting to access any endpoints under /admin/.. Inspect all non-admin public traffic against preconfigured WAF rules for SQL injection (sqli-v33-stable) and Cross-Site Scripting (xss-v33-stable), denying matched exploits. Allow all remaining legitimate customer traffic. How should the Cloud Armor security policy rules and priorities be configured to enforce these requirements correctly?

Configuring web application firewalls (e.g., Google Cloud Armor).

An enterprise integrates an external Identity Provider (IdP) with Google Cloud Identity for Single Sign-On (SSO) and enforces OS Login organization-wide for all Compute Engine instances. A security audit discovers that when departing employees are disabled in the external IdP, they can still establish SSH sessions to Linux VMs via OS Login. How should the security team automate user lifecycle management to immediately revoke both Google Cloud console and OS Login SSH access upon employee departure?

Administering user accounts and groups programmatically.

An enterprise uses Cloud Identity to govern administrative access to Google Cloud projects hosting mission-critical workloads. A recent internal red-team assessment demonstrated that threat actors could execute adversary-in-the-middle (AitM) reverse-proxy phishing attacks to intercept session cookies and bypass standard multi-factor authentication methods, such as SMS codes and mobile authenticator push prompts. The security architect must enforce an authentication policy for all privileged administrators that eliminates credential harvesting and AitM relay attacks. Which 2-Step Verification (2SV) configuration should the architect implement?

Configuring and enforcing 2-step verification.
