Worked example. The correct answer is already marked and every option is explained below, so there is nothing to select here. To answer questions yourself, start the free trial.
A security operations team is investigating suspicious lateral movement within a Google Cloud VPC. The incident response policy requires capturing and analyzing raw packet payloads (Layer 3 through Layer 7)—including full application data—from specific production Compute Engine instances hosting sensitive database workloads.
The capture architecture must meet the following requirements:
Which solution should the team implement?
Google Cloud Packet Mirroring clones full Layer 3 through Layer 7 network traffic (both ingress and egress) directly from the virtual machine's virtual network interface (vNIC) at the Andromeda virtualization layer. It sends an exact copy of the traffic out-of-band to an internal passthrough Network Load Balancer without modifying, slowing down, or terminating the production packet stream.
--is-mirroring-collector. The load balancer distributes the mirrored traffic across an autoscaled backend instance group of collector appliances.This architecture provides enterprise-grade, native network packet capture. It completely decouples security monitoring from production traffic flow, ensuring forensic-level packet visibility with automatic failover and scalability.
