PCNE Implementing a Virtual Private Cloud Practice Question
An engineer is troubleshooting high latency in a VPC and suspects packet drops. Which VPC feature should they enable to get detailed information about network traffic?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
VPC Flow Logs
VPC Flow Logs capture information about IP traffic going to and from network interfaces. They help diagnose packet drops and latency issues. Cloud NAT logging provides logs about NAT connections, not general traffic. Packet Mirroring is for capturing and inspecting traffic for analysis, not for logging. Traffic Director is a service mesh control plane, not a traffic logging tool.

Cloud NAT logging
Why it's wrong here
Cloud NAT logging records NAT connections, but does not provide detailed network traffic information for troubleshooting packet drops.
- ✓
VPC Flow Logs
Why this is correct
VPC Flow Logs capture IP traffic metadata, enabling diagnosis of packet drops and latency issues.
- ✗
Packet Mirroring
Why it's wrong here
Packet Mirroring copies traffic for deep inspection, but is not a logging feature for troubleshooting latency.
- ✗
Traffic Director
Why it's wrong here
Traffic Director is a traffic management control plane for service mesh, not a network traffic logging tool.
