- A
Deploy a Cloud Function that listens on the Pub/Sub topic and uses Compute Engine API to modify the VM's network tags and update firewall rules
Cloud Functions can automate remediation based on SCC findings.
- B
Create a Security Health Analytics scan to detect similar threats
Why wrong: Security Health Analytics scans for misconfigurations, not for responding to existing threats.
- C
Set up a log sink to export Admin Activity logs to BigQuery
Why wrong: This is for analysis, not real-time automated response.
- D
Enable VPC Flow Logs for the affected VM's subnet
Why wrong: VPC Flow Logs provide network monitoring but do not trigger automated responses.
- E
Create a Pub/Sub topic and subscribe SCC findings to it using a notification config
SCC can stream findings to Pub/Sub for real-time processing.
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. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 financial services company uses Security Command Center (SCC) Premium tier to monitor its GCP environment. The security team wants to automatically respond to high-severity threat findings, such as 'Cryptomining' from Event Threat Detection. The response should include isolating the affected VM by removing its external IP and applying a firewall rule to block egress traffic. Which two steps should the team implement? (Choose two.)
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
Deploy a Cloud Function that listens on the Pub/Sub topic and uses Compute Engine API to modify the VM's network tags and update firewall rules
SCC can be integrated with Pub/Sub to send real-time notifications for findings, and Cloud Functions can execute automated remediation actions like modifying VM network tags or applying firewall rules.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.

Common exam traps
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
How this comes up in practice
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.
