The correct answer is to use a lifecycle policy to transition logs to archive storage after 90 days and delete after three years. This is the most cost-effective solution because lifecycle policies automate the movement of data to cheaper storage tiers—such as cold or archive storage—based on age, reducing costs while ensuring compliance with retention requirements. On the CompTIA Cloud+ CV0-004 exam, this concept tests your understanding of cloud storage optimization and compliance automation, often appearing in scenario-based questions where you must balance regulatory mandates with budget constraints. A common trap is choosing hot storage for the full duration, which is unnecessarily expensive, or manual compression, which lacks scalability. Remember the memory tip: “Transition to cold, delete when old” to quickly recall that lifecycle policies automate cost-effective log retention for compliance without manual intervention.
CV0-004 Operations and Support Practice Question
This CV0-004 practice question tests your understanding of operations and support. 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 cloud administrator needs to ensure that application logs are retained for three years to comply with regulatory requirements. Which of the following is the MOST cost-effective solution?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a lifecycle policy to transition logs to archive storage after 90 days and delete after three years
Option B is correct because setting a lifecycle policy to transition logs to cold storage after a period and then delete after three years reduces cost. Option A is wrong because storing all logs in hot storage for three years is expensive. Option C is wrong because preventing log rotation would not help with cost and may cause storage issues. Option D is wrong because compressing old logs manually is less efficient than automated lifecycle.
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.
✗
Configure log rotation so only the last 30 days of logs are kept in the instance
Why it's wrong here
This violates compliance requirement of three-year retention.
✗
Store all logs in block storage for three years
Why it's wrong here
Block storage is expensive for long-term retention.
✓
Use a lifecycle policy to transition logs to archive storage after 90 days and delete after three years
Why this is correct
Lifecycle policies automate tiering to cost-effective storage.

Read the scenario before looking for a memorised answer.
✗
Compress old logs manually and store them in a separate volume
Why it's wrong here
Manual process is inefficient and does not leverage automated storage tiers.
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 practitioner preparing for the CV0-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
