This DEA-C01 practice question tests your understanding of data store management. 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 using Amazon RDS for MySQL and wants to automate backups for point-in-time recovery. Which TWO actions should be taken? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable automated backups with a retention period.
Options B and D are correct. Automated backups are enabled by default, and the retention period can be set up to 35 days. Option A is wrong because manual snapshots are not automated. Option C is wrong because Multi-AZ is for high availability, not backups. Option E is wrong because AWS Backup is an optional service but not required; RDS native backups suffice.
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.
✓
Enable automated backups with a retention period.
Why this is correct
Automated backups provide point-in-time recovery and are enabled by default.
Related concept
Static NAT maps one inside address to one outside address.
✗
Use AWS Backup to schedule backups.
Why it's wrong here
AWS Backup is an alternative but not necessary; RDS native automated backups already exist.
✓
Set the backup retention period to the desired number of days.
Why this is correct
Retention period determines how long automated backups are kept.
Related concept
Static NAT maps one inside address to one outside address.
✗
Enable Multi-AZ deployment.
Why it's wrong here
Multi-AZ provides failover, not backups.
✗
Take manual snapshots daily.
Why it's wrong here
Manual snapshots are not automated; they require manual intervention.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
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 DEA-C01 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Enable automated backups with a retention period. — Options B and D are correct. Automated backups are enabled by default, and the retention period can be set up to 35 days. Option A is wrong because manual snapshots are not automated. Option C is wrong because Multi-AZ is for high availability, not backups. Option E is wrong because AWS Backup is an optional service but not required; RDS native backups suffice.
