The answer is to generate a signed URL and use an HTTP PUT request from the application. This approach is correct because a signed URL provides time-limited, permissioned access to a specific Cloud Storage object, allowing the legacy app to upload files directly via a standard HTTP request without needing any SDK, library, or additional software installed on the on-premises server. On the Google Professional Cloud Developer exam, this scenario tests your understanding of secure, agentless upload methods for environments with strict installation restrictions; a common trap is assuming the gcloud CLI or Cloud Storage FUSE is available, but both require software that cannot be installed per the prompt. Remember the key constraint: no new software means you must rely on HTTP alone, and signed URLs are the only native Cloud Storage feature that enables this. Memory tip: think “Signed URL = No install, just PUT.”
PCD Integrating Google Cloud services Practice Question
This PCD practice question tests your understanding of integrating google cloud services. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 developer is integrating a legacy on-premises application with Cloud Storage. The application generates files that must be uploaded to a bucket. The developer cannot install any additional software on the on-premises server. Which approach should the developer use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Generate a signed URL and use an HTTP PUT request from the application.
Option C is correct because using a signed URL allows the application to upload files directly via HTTP without needing a Google Cloud SDK or library. Option A is wrong because the gcloud CLI may not be installed. Option B is wrong because Cloud Storage FUSE requires a FUSE driver installation. Option D is wrong because Cloud Functions is an additional service, not a direct upload method.
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.
✗
Use the gcloud CLI to copy files to the bucket.
Why it's wrong here
The gcloud CLI requires installation, which is not allowed.
✓
Generate a signed URL and use an HTTP PUT request from the application.
Why this is correct
A signed URL provides time-limited access to upload objects without additional software.
Related concept
Read the scenario before looking for a memorised answer.
✗
Mount the bucket using Cloud Storage FUSE.
Why it's wrong here
FUSE requires client software installation.
✗
Deploy a Cloud Function that accepts file uploads and writes to the bucket.
Why it's wrong here
This adds complexity and requires the application to send data to the function, not directly to storage.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

TExam Day Tips
→Underline the problem statement mentally.
→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 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.
