Cloud Technology and Services →mediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is Amazon Aurora. This is the correct choice because Aurora is a fully managed, MySQL-compatible relational database that delivers up to 5x the performance of standard MySQL by using a distributed, fault-tolerant storage subsystem that auto-scales and self-heals, while remaining fully compatible with existing MySQL drivers and tools so no application changes are needed. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of the key differentiators between managed database services—specifically, Aurora’s performance boost and seamless MySQL compatibility are often contrasted with RDS MySQL, which lacks that 5x performance claim. A common trap is choosing Amazon RDS for MySQL, but RDS does not offer the same performance multiplier; Aurora is the only service that explicitly promises up to 5x throughput. Memory tip: think “Aurora = 5x MySQL” — the name itself suggests a bright, fast upgrade over standard MySQL.

CLF-C02 Cloud Technology and Services Practice Question

This CLF-C02 practice question tests your understanding of cloud technology and services. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 runs a MySQL database and wants to migrate to a cloud-native relational database that is fully managed, provides up to 5x the performance of standard MySQL, offers automated backups with point-in-time recovery, and is compatible with MySQL drivers and tools without application changes. Which AWS service meets these requirements?

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

✓

Amazon Aurora

Amazon Aurora is a fully managed, MySQL-compatible relational database that delivers up to 5x the performance of standard MySQL, provides automated backups with point-in-time recovery, and is designed to work with existing MySQL drivers and tools without requiring application changes. This makes it the ideal choice for migrating a MySQL database to a cloud-native, high-performance relational database service.

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.

  • ✗

    Amazon RDS for MySQL

    Why it's wrong here

    RDS for MySQL is a managed MySQL service that matches standard MySQL performance. Aurora is MySQL-compatible but provides significantly higher performance (up to 5x) for the same hardware footprint.

  • ✗

    Amazon DynamoDB

    Why it's wrong here

    DynamoDB is a NoSQL key-value database. It is not MySQL-compatible and would require significant application rewriting to migrate a relational MySQL workload.

  • ✓

    Amazon Aurora

    Why this is correct

    Aurora is AWS's cloud-native relational database that is fully compatible with MySQL and PostgreSQL. It provides up to 5x the performance of standard MySQL, automated backups, and continuous replication to six copies across three AZs.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Amazon Redshift

    Why it's wrong here

    Redshift is a data warehouse for analytical workloads. It is not MySQL-compatible and is not designed for OLTP transactional workloads.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may confuse Amazon RDS for MySQL with Aurora, overlooking the specific performance multiplier (up to 5x) and the cloud-native architecture that distinguishes Aurora from standard MySQL on RDS.

Detailed technical explanation

How to think about this question

Aurora achieves its performance advantage through a distributed, SSD-backed storage subsystem that separates compute and storage, allowing for faster replication and automatic failover. It also uses a 6-way replication across three Availability Zones and a quorum-based write model, which enables consistent, low-latency commits. In real-world scenarios, Aurora can handle high-traffic OLTP workloads that would overwhelm standard MySQL, making it a common choice for SaaS applications requiring both high throughput and MySQL compatibility.

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.

TExam Day Tips

  • 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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
