Quick Answer
The answer is AWS Shield Advanced, AWS WAF, and AWS Firewall Manager. These three services work together to detect and protect against DDoS attacks by providing layered defense: AWS Shield Advanced offers always-on detection and cost protection against large volumetric attacks, AWS WAF filters malicious web traffic at the application layer using custom rules, and AWS Firewall Manager centrally enforces those WAF rules and Shield protections across an organization’s accounts. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this question tests your understanding of the AWS shared responsibility model for DDoS mitigation, often appearing as a multi-select item where common traps include confusing logging services like VPC Flow Logs or configuration tools like AWS Config with active protection mechanisms. A useful memory tip is to think of the three layers as “Shield for scale, WAF for web, Firewall Manager for governance”—each addresses a distinct attack vector, and only these three provide direct detection and active protection against DDoS threats.
This ANS-C01 practice question tests your understanding of network security, compliance and governance. 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.
Which THREE services can be used to detect and protect against DDoS attacks? (Choose THREE.)
AWS Firewall Manager
Centrally manages DDoS protection rules.
AWS Config
Why wrong: Tracks configuration changes, not DDoS.
AWS Shield Advanced
Provides DDoS protection.
AWS WAF
Filters malicious web traffic.
VPC Flow Logs
Why wrong: Only logs traffic, does not protect.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
AWS Firewall Manager
Options A, B, and C are correct. AWS Shield Advanced provides DDoS protection, AWS WAF filters web traffic, and AWS Firewall Manager centrally manages rules. Option D is wrong because VPC Flow Logs only log traffic. Option E is wrong because AWS Config tracks configuration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
