GCDL Practice Question: A startup's web application is being targeted by…
This GCDL practice question tests your understanding of a startup's web application is being targeted by…. 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 startup's web application is being targeted by a denial-of-service attack that is flooding its servers with millions of fake requests per second. Which Google Cloud product provides automatic DDoS protection for the application?
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
Best answer
Cloud Armor, which provides DDoS protection and WAF capabilities to detect and mitigate volumetric attacks against the application
Cloud Armor is Google Cloud's DDoS mitigation and WAF service. It integrates with Google's global load balancers to absorb volumetric attacks at the edge before they reach backend servers. Its Adaptive Protection feature automatically detects and responds to DDoS patterns in real time.
B
Distractor review
Cloud Monitoring, by alerting the team so they can manually scale up servers to absorb the attack
Cloud Monitoring detects and alerts but doesn't mitigate attacks. Manual scaling in response to a multi-million RPS attack is too slow. Automatic DDoS mitigation at the network edge (Cloud Armor) is required.
C
Distractor review
Cloud IAM, by revoking permissions for the IP addresses generating attack traffic
Cloud IAM controls access to Google Cloud resources through authentication and authorization. It operates on authenticated principals, not arbitrary external IP addresses. It cannot block DDoS attack traffic.
D
Distractor review
Cloud Storage, by distributing the static content of the application across multiple storage regions
Cloud Storage serves static content but provides no DDoS protection mechanism against attack traffic targeting the application.
Common exam trap
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.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
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.

FAQ
Questions learners often ask
What does this GCDL question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Cloud Armor, which provides DDoS protection and WAF capabilities to detect and mitigate volumetric attacks against the application — Google Cloud Armor provides DDoS protection and web application firewall capabilities. For applications behind Google Cloud's global load balancers, Google also provides infrastructure-level DDoS protection automatically. Cloud Armor adds adaptive protection that detects and mitigates volumetric DDoS attacks, layer 7 attacks, and common web exploits.
What should I do if I get this GCDL question wrong?
Identify which GCDL exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
