Google ACE Planning and configuring a cloud solution Practice Question
This ACE practice question tests your understanding of planning and configuring a cloud solution. 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.
Exhibit
Refer to the exhibit.
$ gsutil ls -L gs://my-bucket/logs/
...
Objects:
gs://my-bucket/logs/2023-01-01.log:
Storage class: ARCHIVE
Content-Type: text/plain
gs://my-bucket/logs/2023-01-02.log:
Storage class: ARCHIVE
Content-Type: text/plain
Total: 2 objects, 250 MB
The company wants to change the storage class of these log files to Nearline to reduce costs while still retaining the ability to access them without restoration fees. Which command should be used?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
Option B is correct because the `gsutil rewrite` command is specifically designed to change the storage class of existing objects without incurring restoration fees. It rewrites the object metadata to the new storage class (Nearline) while keeping the object in place, and the operation does not require retrieving the object from cold storage, so no restoration charges apply.
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.
✗
gsutil cp -s NEARLINE gs://my-bucket/logs/*.log
Why it's wrong here
cp creates copies; it does not change the original object's storage class.
mv moves objects but does not change storage class; it actually copies then deletes.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse `gsutil rewrite` with `gsutil cp` or `gsutil mv`, assuming any command with `-s` can change storage class, but only `rewrite` avoids restoration fees by modifying the object in place without creating a new copy.
Detailed technical explanation
How to think about this question
The `gsutil rewrite` command works by performing a server-side rewrite of the object, which updates the storage class metadata without downloading and re-uploading the data. This is critical for objects in Nearline or Coldline storage classes, as a standard copy or move operation would trigger a retrieval (restoration) charge. The command uses the same underlying API as `gsutil cp` but with the `-s` flag to specify the target storage class, and it avoids the need for a temporary copy by rewriting the object in place.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.

What is the correct answer to this question?
The correct answer is: gsutil rewrite -s NEARLINE gs://my-bucket/logs/*.log — Option B is correct because the `gsutil rewrite` command is specifically designed to change the storage class of existing objects without incurring restoration fees. It rewrites the object metadata to the new storage class (Nearline) while keeping the object in place, and the operation does not require retrieving the object from cold storage, so no restoration charges apply.
