Full question →mediummultiple choiceObjective-mapped
A company stores product images in an Amazon S3 bucket. New images are accessed frequently for the first 30 days, but access drops sharply after that. The company wants to automatically optimize storage costs by moving data between access tiers without any manual intervention or upfront lifecycle policy setup. Which Amazon S3 storage class should the company use to meet these requirements?
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
Amazon S3 Intelligent-Tiering
Correct. S3 Intelligent-Tiering automatically moves objects between frequent and infrequent access tiers based on changing access patterns, achieving cost optimization without manual lifecycle policies.
B
Distractor review
Amazon S3 Standard
Incorrect. S3 Standard is designed for frequently accessed data. It does not automatically transition objects to lower-cost tiers, so costs remain high for data that is rarely accessed after the initial period.
C
Distractor review
Amazon S3 One Zone-Infrequent Access
Incorrect. S3 One Zone-IA is suitable for infrequently accessed data but lacks automatic tiering. Objects must be explicitly moved using lifecycle policies. Additionally, it stores data in a single Availability Zone, which may not meet durability requirements for product images.
D
Distractor review
Amazon S3 Glacier Deep Archive
Incorrect. S3 Glacier Deep Archive is the lowest-cost storage class for long-term archival data with retrieval times of 12 hours or more. It is not designed for data that may be accessed frequently or for automatic tiering based on changing access patterns.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

Question 1
A developer needs to launch a test server for a new application prototype. The developer logs into the AWS Management Console, selects an Amazon EC2 instance type, configures the security group, and starts the instance. The instance is running within two minutes, and the developer did not need to submit a formal request to the company's IT procurement team or wait for approval from a cloud administrator. Which essential characteristic of cloud computing does this scenario best demonstrate?
Question 2
A solutions architect is planning a new web application on AWS. The workload will include 3 Amazon EC2 instances (t3.medium) running 24/7, an Application Load Balancer, and an Amazon RDS for MySQL db.t3.small database. The architect needs to estimate the monthly cost for the first year, considering different purchasing options (On-Demand, 1-year All Upfront Reserved Instance, and Compute Savings Plan). Which AWS tool should the architect use to create this estimate?
Question 3
A company's development team frequently needs temporary test environments. A developer can log into the AWS Management Console, select an Amazon EC2 instance type, configure storage, and launch the instance within minutes without any interaction with the IT infrastructure team. This capability is an example of which essential characteristic of cloud computing?
Question 4
A company's finance team needs to analyze AWS spending in detail. They require a report that includes hourly cost data for each AWS service, each individual resource (e.g., a specific EC2 instance), and any cost allocation tags applied. The team plans to export this data to an Amazon S3 bucket and then import it into a custom business intelligence (BI) analytics dashboard. Which AWS tool should the finance team use to generate this level of detailed cost data?
Question 5
A company uses AWS for its development environment. The finance team wants to set a monthly budget of $10,000. They want to receive an email notification when the actual costs reach 80% of the budget ($8,000) and again when costs exceed the budget. The team needs a managed AWS service that can automatically send these alerts without requiring custom code or third-party tools. Which AWS service should the team use?
Question 6
A company uses AWS Organizations to manage multiple accounts. The security team needs to enforce a policy that restricts SSH access (port 22) from the internet (0.0.0.0/0) in all VPCs across all accounts. The team wants to centrally define the allowed rules and automatically apply them to newly created VPCs and security groups, while also automatically remediating any existing non-compliant security groups. Which AWS service should the team use?
FAQ
Questions learners often ask
What does this CLF-C02 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Amazon S3 Intelligent-Tiering — Amazon S3 Intelligent-Tiering is designed for data with unknown or changing access patterns. It automatically moves objects between three access tiers: Frequent Access, Infrequent Access, and Archive Instant Access, optimizing storage costs without requiring manual lifecycle rules. S3 Standard does not automatically reduce costs for infrequently accessed data. S3 One Zone-IA is for infrequently accessed data but requires explicit lifecycle rules and does not automatically move data between tiers. S3 Glacier Deep Archive is the lowest-cost storage class but is intended for long-term archival data that is rarely accessed and has retrieval times of hours; it is not suitable for automatic cost optimization across varying access patterns.
