DOP-C02 Incident and Event Response Practice Question
This DOP-C02 practice question tests your understanding of incident and event response. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 uses Amazon RDS for MySQL and has enabled automated backups. The database administrator accidentally deleted a critical row from a table. The deletion occurred 15 minutes ago. What is the fastest way to recover the lost data?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Perform a Point-in-Time Restore to a time just before the deletion.
Option C is correct because Point-in-Time Restore (PITR) allows restoring to any time within the backup retention period, down to the second. Option A is wrong because a manual snapshot from before the deletion would need to be created, which is slower. Option B is wrong because the binlog contains changes, but replaying requires manual effort and is not the fastest AWS-native method. Option D is wrong because RDS does not have a native 'undo' feature.
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.
✓
Perform a Point-in-Time Restore to a time just before the deletion.
Why this is correct
Fastest AWS-native method to recover to a specific point.
Related concept
Static NAT maps one inside address to one outside address.
✗
Use the RDS console to undo the last transaction.
Why it's wrong here
No such feature exists.
✗
Use the binary log to replay transactions before the deletion.
Why it's wrong here
Requires manual binlog parsing; not the fastest.
✗
Create a manual snapshot of the current instance and restore it.
Why it's wrong here
Manual snapshot includes the deletion; not fast.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
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 DOP-C02 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Perform a Point-in-Time Restore to a time just before the deletion. — Option C is correct because Point-in-Time Restore (PITR) allows restoring to any time within the backup retention period, down to the second. Option A is wrong because a manual snapshot from before the deletion would need to be created, which is slower. Option B is wrong because the binlog contains changes, but replaying requires manual effort and is not the fastest AWS-native method. Option D is wrong because RDS does not have a native 'undo' feature.
