This ACE practice question tests your understanding of a security team needs an inventory of all compute…. 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 security team needs an inventory of all Compute Engine VM instances across all projects in their GCP organization, including instance names, zones, and status, without logging into each project individually. Which service provides this?

A security team needs an inventory of all Compute Engine VM instances across all projects in their GCP organization, including instance names, zones, and status, without logging into each project individually. Which service provides this?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Distractor review

BigQuery information_schema views for GCP compute resources

BigQuery information_schema contains metadata about BigQuery datasets — not GCP Compute Engine instances.

B

Distractor review

Cloud Monitoring — use the metric explorer to list all VM instances

Cloud Monitoring tracks metrics (CPU, memory) — it doesn't provide a resource inventory query interface across projects.

C

Best answer

Cloud Asset Inventory with an organization-scoped asset search

`gcloud asset search-all-resources --scope=organizations/[ORG_ID] --asset-types=compute.googleapis.com/Instance` returns all VMs across all projects in the organization.

D

Distractor review

Cloud Resource Manager — list all projects and then query each for VMs

Resource Manager manages projects but doesn't provide cross-project resource inventory — querying each project individually is exactly what Asset Inventory avoids.

Common exam trap

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.

Technical deep dive

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.

FAQ

Questions learners often ask

What does this ACE question test?

Static NAT maps one inside address to one outside address.

What is the correct answer to this question?

The correct answer is: Cloud Asset Inventory with an organization-scoped asset search — Cloud Asset Inventory provides a full inventory of GCP resources across an organization or folder, queryable via API or `gcloud asset search-all-resources`. It eliminates the need to query each project individually and supports searching by resource type, location, and metadata.

What should I do if I get this ACE question wrong?

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 ACE NAT questions on configuration and troubleshooting.
