The answer is 30 days, as Google Cloud projects have a 30-day soft-delete recovery window after deletion. This is because when a project is deleted, it enters a soft-delete state where all resources and configurations are preserved but inaccessible, allowing administrators to restore the project using the `gcloud projects undelete` command or the Cloud Resource Manager API within that period. On the Google Associate Cloud Engineer exam, this concept tests your understanding of project lifecycle management and recovery procedures, often appearing as a straightforward question where the trap is confusing the 7-day window for some other services or assuming permanent deletion occurs immediately. A common memory tip is to think of the 30-day window as a full month of grace, similar to a credit card refund period, ensuring you have ample time to catch accidental deletions. Remember: 30 days to undelete, not 7 or 14.
Google ACE Setting up a cloud solution environment Practice Question
This ACE practice question tests your understanding of setting up 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.
A project was accidentally deleted. A GCP administrator realizes the mistake 3 days later. What is the maximum time window in which the project can be restored?
24 hours — projects are permanently deleted after one day
Why wrong: GCP provides a 30-day recovery window, not 24 hours.
B
7 days — projects enter a one-week soft-delete period
Why wrong: The soft-delete period is 30 days, not 7 days.
C
30 days — projects can be restored using `gcloud projects undelete` within this window
Deleted projects remain recoverable for 30 days. `gcloud projects undelete [PROJECT_ID]` or the Console's Resource Manager page can restore the project during this period.
D
Projects are permanently deleted immediately and cannot be recovered
Why wrong: GCP's 30-day grace period specifically exists to protect against accidental deletion.

Correct answer & explanation
✓
30 days — projects can be restored using `gcloud projects undelete` within this window
Option C is correct because Google Cloud projects have a 30-day soft-delete period after deletion. During this window, the project can be recovered using the `gcloud projects undelete` command or the Cloud Resource Manager API, restoring all associated resources and configurations.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
24 hours — projects are permanently deleted after one day
Why it's wrong here
GCP provides a 30-day recovery window, not 24 hours.
✗
7 days — projects enter a one-week soft-delete period
Why it's wrong here
The soft-delete period is 30 days, not 7 days.
✓
30 days — projects can be restored using `gcloud projects undelete` within this window
Why this is correct
Deleted projects remain recoverable for 30 days. `gcloud projects undelete [PROJECT_ID]` or the Console's Resource Manager page can restore the project during this period.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse the 30-day project soft-delete period with shorter retention windows for other GCP services (like 7-day backup retention for Cloud SQL or 24-hour snapshot deletion), leading them to underestimate the recovery window.
Detailed technical explanation
How to think about this question
When a project is deleted, the Cloud Resource Manager marks it as 'DELETE_REQUESTED' and begins a 30-day countdown. During this period, the project's resources (e.g., Compute Engine instances, Cloud Storage buckets) are not immediately destroyed but become inaccessible to prevent accidental data loss. After 30 days, the project and its resources are permanently purged and cannot be recovered. The `gcloud projects undelete` command sends a request to the `projects.undelete` API method, which restores the project's lifecycle state to 'ACTIVE'.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
