SOA-C02 Networking and Content Delivery Practice Question

This SOA-C02 practice question tests your understanding of networking and content delivery. 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 deliver video content to users worldwide. The content is stored in an S3 bucket. The SysOps administrator notices that users in some geographic regions experience high latency when loading the video. The administrator wants to improve the performance for these users without changing the existing infrastructure. The CloudFront distribution is configured with the default cache behavior. What is the MOST cost-effective solution to reduce latency for users in those regions?

A
Increase the cache TTL for the content.
Why wrong: TTL does not affect latency for cache misses.
B
Change the CloudFront distribution's price class to include all edge locations.
Using all edge locations reduces latency.
C
Add additional S3 buckets in different regions and configure multiple origins.
Why wrong: Multiple origins can help but increase cost and complexity.
D
Use multiple CloudFront distributions for different geographic regions.
Why wrong: Increases cost and management overhead.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Change the CloudFront distribution's price class to include all edge locations.

Option B is correct because CloudFront's Price Class All includes all edge locations worldwide, reducing latency for users in all regions without changing the existing infrastructure. Option A is wrong because increasing cache TTL does not reduce latency for initial requests; it only increases the time content stays cached. Option C is wrong because adding more S3 buckets in different regions and configuring multiple origins increases complexity and cost, and is not the most cost-effective solution. Option D is wrong because using multiple CloudFront distributions increases cost and management overhead, and is not necessary when a single distribution with Price Class All can cover all regions.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.

Detailed technical explanation

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.

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.
