- A
Cloud NAT logs
Why wrong: NAT logs show connections but are less granular; VPC Flow Logs are better.
- B
VPC Flow Logs
Shows source/destination IPs, ports, protocols for all network flows.
- C
Compute Engine serial port output
Why wrong: Serial output shows OS-level messages but not network traffic.
- D
Cloud Audit Logs (Data Access)
Logs data access to services like BigQuery or Cloud Storage, showing if data was read.
- E
Cloud DNS logging
Shows DNS queries made by the VM, which may reveal exfiltration domains.

PCSE Practice Question: Managing Operations in a Cloud Solution Environment
This PCSE practice question tests your understanding of managing operations in a cloud solution environment. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A security engineer is investigating a potential data exfiltration incident. They suspect that a compromised VM is sending sensitive data to an external IP. Which three data sources should they examine to trace the exfiltration? (Choose three.)
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 network metadata, DNS queries can show domain lookups, and Cloud Audit Logs (Data Access) can log data access events. Cloud NAT logs show outbound connections but are not as detailed for exfiltration. Compute Engine serial port output shows console logs but not network traffic.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Trap categories for this question
Command / output trap
NAT logs show connections but are less granular; VPC Flow Logs are better.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
