- A
gcloud projects activate new-project; gcloud config list
Why wrong: `gcloud projects activate` is not a valid command. Use `gcloud config set project`.
- B
gcloud config set project new-project; gcloud config list
`gcloud config set project` updates the active project and `gcloud config list` confirms the new setting — a clean, targeted approach.
- C
gcloud auth login --project=new-project; gcloud config list
Why wrong: `--project` is not a valid flag for `gcloud auth login`. Authentication and project selection are separate concerns.
- D
export GCLOUD_PROJECT=new-project; gcloud config list
Why wrong: The environment variable is `GOOGLE_CLOUD_PROJECT` or `CLOUDSDK_CORE_PROJECT` — not `GCLOUD_PROJECT`. Even the correct variable name only works for some SDK calls.
Quick Answer
The answer is to run `gcloud config set project new-project` followed by `gcloud config list`. This is correct because `gcloud config set project` updates the active project property in your local CLI configuration, directly changing the target for all subsequent gcloud commands, while `gcloud config list` then displays the full current configuration, including the newly set project, to verify the switch. On the Google Associate Cloud Engineer exam, this tests your understanding of how gcloud manages configuration properties and the importance of verifying changes before proceeding with resource operations. A common trap is assuming the project changes automatically after a single command or forgetting to verify, leading to accidental work in the wrong project. Remember the two-step mantra: "Set it, then list it" — set the project first, then list the config to confirm the switch stuck.
Google ACE Setting up a cloud solution environment Practice Question
This ACE practice question tests your understanding of setting up a cloud solution environment. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
During a gcloud CLI session, a developer runs `gcloud config list` and sees the output shows `project = old-project`. They need to work in `new-project`. Which sequence of commands correctly switches projects and verifies the change?
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
gcloud config set project new-project; gcloud config list
Option B is correct because `gcloud config set project new-project` updates the active project in the local CLI configuration, and `gcloud config list` then displays the current configuration, confirming the change. This is the standard method to switch the working project for subsequent gcloud commands.
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.
- ✗
gcloud projects activate new-project; gcloud config list
Why it's wrong here
`gcloud projects activate` is not a valid command. Use `gcloud config set project`.
- ✓
gcloud config set project new-project; gcloud config list
Why this is correct
`gcloud config set project` updates the active project and `gcloud config list` confirms the new setting — a clean, targeted approach.

Read the scenario before looking for a memorised answer.
- ✗
gcloud auth login --project=new-project; gcloud config list
Why it's wrong here
`--project` is not a valid flag for `gcloud auth login`. Authentication and project selection are separate concerns.
- ✗
export GCLOUD_PROJECT=new-project; gcloud config list
Why it's wrong here
The environment variable is `GOOGLE_CLOUD_PROJECT` or `CLOUDSDK_CORE_PROJECT` — not `GCLOUD_PROJECT`. Even the correct variable name only works for some SDK calls.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the distinction between environment variables and configuration file settings, trapping candidates who think setting `GCLOUD_PROJECT` will update the output of `gcloud config list`.
Trap categories for this question
Command / output trap
`gcloud projects activate` is not a valid command. Use `gcloud config set project`.
Detailed technical explanation
How to think about this question
The `gcloud config set` command modifies the `~/.config/gcloud/configurations/config_default` file (or an active named configuration), which is the persistent source of truth for the active project. The `GCLOUD_PROJECT` environment variable takes precedence over the config file for API calls, but `gcloud config list` explicitly reads the config file, not environment variables, making option D ineffective for verification. Understanding this precedence is critical when scripting or using CI/CD pipelines where environment variables might be set.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
