Full question →mediummultiple choiceObjective-mapped
A company uses Amazon S3 to store raw data files for a data analytics platform. The company requires that files remain immediately accessible for the first 30 days after upload. After 30 days, files must be automatically moved to a lower-cost storage class for archival access. After 7 years, files must be automatically deleted. The company wants to implement this data management strategy with minimal ongoing effort. Which AWS S3 feature should the company use?
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
S3 Lifecycle policies
This is correct. S3 Lifecycle policies allow you to define rules for transitioning objects to other storage classes after a specified number of days and for expiring (deleting) objects after a set period. This automates the company's data management requirements.
B
Distractor review
S3 Intelligent-Tiering
S3 Intelligent-Tiering automatically moves data between access tiers (frequent, infrequent, archive) based on changing access patterns, but it does not support fixed time-based transitions or automatic deletion after a specific date. It cannot enforce the 30-day and 7-year rules required.
C
Distractor review
S3 Object Lock
S3 Object Lock is used to prevent objects from being deleted or overwritten for a fixed period of time. It does not automate transitions to other storage classes or provide scheduled deletion.
D
Distractor review
S3 Versioning
S3 Versioning preserves multiple versions of an object to protect against accidental overwrites and deletions. It does not automate moving data between storage classes or deleting objects based on age.
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: S3 Lifecycle policies — Amazon S3 Lifecycle policies allow you to define rules that automatically transition objects to a different storage class (e.g., from S3 Standard to S3 Glacier Deep Archive) and also expire (delete) objects after a specified period. This enables automated, cost-effective data management without manual intervention. S3 Intelligent-Tiering automatically moves data between access tiers based on changing usage patterns, but it does not support fixed time-based transitions or deletion rules. S3 Object Lock prevents objects from being deleted or overwritten for a fixed period; it does not automate transitions. S3 Versioning protects against accidental overwrites by preserving multiple versions of an object, but it does not automate lifecycle transitions or deletions.
