Quick Answer
The answer is Cloud Logging with log sinks. This service is correct because log sinks allow you to route audit logs from multiple source projects to a centralized destination, such as a Cloud Storage bucket or BigQuery dataset in a separate project, fulfilling the security policy requirement for log aggregation. On the Google Professional Cloud Security Engineer exam, this concept tests your understanding of centralized monitoring and compliance controls, often appearing in scenarios where you must separate log storage from operational workloads to prevent tampering. A common trap is confusing log sinks with Cloud Monitoring, which handles metrics and alerting, not log routing, or with Security Command Center, which focuses on findings and compliance posture. Remember the memory tip: “Sinks send logs, sinks sink logs” — if you need to move logs out of a project, think of a sink as the plumbing that drains them to a central location.
This PCSE practice question tests your understanding of managing operations in a cloud solution environment. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
An organization's security policy requires that all audit logs be stored in a separate project for centralized monitoring. Which Google Cloud service should be used to aggregate logs from multiple projects?
Cloud Monitoring
Why wrong: Cloud Monitoring is used for metrics and dashboards, not for aggregating log data.
Cloud Audit Logs
Why wrong: Cloud Audit Logs are a category of logs, not a service for aggregation.
Security Command Center
Why wrong: Security Command Center provides security findings and posture, not log aggregation.
Cloud Logging with log sinks
Log sinks can aggregate logs from multiple projects to a centralized destination.

Correct answer & explanation
Cloud Logging with log sinks
Option C is correct because Cloud Logging log sinks can be configured to route logs from multiple projects to a common destination like a Cloud Storage bucket or BigQuery dataset in a separate project. Option A is for metrics and alerting, not log aggregation. Option B is a type of log, not a service. Option D is for security findings and compliance, not log aggregation.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Cloud Monitoring
Why it's wrong here
Cloud Monitoring is used for metrics and dashboards, not for aggregating log data.
Cloud Audit Logs
Why it's wrong here
Cloud Audit Logs are a category of logs, not a service for aggregation.
Security Command Center
Why it's wrong here
Security Command Center provides security findings and posture, not log aggregation.
Cloud Logging with log sinks
Why this is correct
Log sinks can aggregate logs from multiple projects to a centralized destination.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
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
Security Command Center provides security findings and posture, not log aggregation.
Detailed technical explanation
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.
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
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PCSE NAT questions on configuration and troubleshooting.
