PCSE Practice Question: Managing Operations in a Cloud Solution Environment
A security team wants to analyze VPC Flow Logs to investigate a potential data exfiltration incident. The logs are currently stored in Cloud Logging. What is the MOST efficient method to query and visualize the network traffic patterns?
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
✓
Use Log Analytics in Cloud Logging with SQL queries
Log Analytics (powered by BigQuery) in Cloud Logging provides SQL-based analysis directly on logs without needing to export.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use Log Analytics in Cloud Logging with SQL queries
Why this is correct
Log Analytics allows SQL queries on logs stored in Logging buckets, enabling analysis without export.
- ✗
Enable VPC Flow Logs on a new VM and capture traffic
Why it's wrong here
This would not help analyze historical logs.
- ✗
Export logs to Cloud Storage and analyze with a local tool
Why it's wrong here
Exporting to Cloud Storage adds latency and requires manual analysis.
- ✗
Create a log sink to BigQuery and use BigQuery for analysis
Why it's wrong here
Creating a log sink to BigQuery introduces latency from the streaming buffer and requires manual SQL queries, lacking the built-in, real-time querying and dashboarding capabilities of the correct option that directly analyses logs in Cloud Logging. It is tempting because BigQuery excels at large-scale, ad-hoc analytical queries on structured data and would be ideal if the team needed long-term retention and complex joins across multiple datasets.
