The correct answer is to use an S3 Lifecycle Policy to transition logs to S3 Glacier after 30 days. This approach works because the S3 Lifecycle Policy automates both the storage class transition and the eventual deletion of objects, so once the 30-day retention period expires, the logs are moved to Glacier for cost-effective long-term storage without any manual scripting or additional services. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding of how to handle SAP HANA database logs backup with minimal operational overhead, specifically avoiding complex solutions like AWS Backup (which targets EC2 instances, not log files) or CloudWatch Logs (which lacks native automatic deletion after a fixed retention period). A common trap is overcomplicating the answer with manual lifecycle rules or scripts when a simple S3 Lifecycle Policy directly meets the requirement. Memory tip: think “S3 Lifecycle = set it and forget it” for log retention.
PAS-C01 Operations and Maintenance Practice Question
This PAS-C01 practice question tests your understanding of operations and maintenance. 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 is running an SAP HANA database on an AWS EC2 instance. The system administrator needs to ensure that the database logs are automatically backed up to Amazon S3 and retained for 30 days. Which combination of AWS services can achieve this with minimal operational overhead?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use an S3 Lifecycle Policy to transition logs to S3 Glacier after 30 days.
Option B is correct because it uses a Lifecycle Policy to transition logs to S3 Glacier after 30 days, meeting the retention requirement with minimal overhead. Option A involves manual scripting and lifecycle rules that don't automatically delete logs after 30 days. Option C uses CloudWatch Logs but doesn't automatically delete logs after 30 days. Option D uses AWS Backup, which is for EC2 backups, not log files.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use Amazon CloudWatch Logs with a retention policy of 30 days.
Why it's wrong here
CloudWatch Logs can expire after 30 days but is not specifically for HANA logs.
✓
Use an S3 Lifecycle Policy to transition logs to S3 Glacier after 30 days.
Why this is correct
Glacier is cost-effective for long-term retention and the policy can delete after 30 days.
Related concept
Static NAT maps one inside address to one outside address.
✗
Use an S3 Lifecycle Policy to transition logs to S3 Standard-IA after 30 days.
Why it's wrong here
This retains logs indefinitely, not just 30 days.
✗
Use AWS Backup to schedule backups of the EC2 instance.
Why it's wrong here
AWS Backup backs up the entire instance, not just logs.
Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PAS-C01 NAT questions on configuration and troubleshooting.
