DOP-C02 Incident and Event Response Practice Question
This DOP-C02 practice question tests your understanding of incident and event response. 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.
A company uses Amazon CloudFront to distribute content globally. Users in certain geographic regions report slow load times. Which TWO configurations can improve performance for these users? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement Lambda@Edge to optimize content delivery.
Option A is correct because CloudFront edge locations cache content closer to users. Option C is correct because Lambda@Edge can perform custom processing at edge locations, such as URL rewriting or A/B testing, which can optimize content delivery. Option B is wrong because S3 Transfer Acceleration speeds up uploads, not downloads. Option D is wrong because a Network Load Balancer is for TCP/UDP traffic, not HTTP/HTTPS content. Option E is wrong because ElastiCache is for database caching, not CDN.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
