The correct answer is a daily full backup combined with transaction log backups every 5 minutes. This strategy works because transaction logs record every individual database change as it happens, allowing you to restore the full backup and then replay each log up to the exact moment before a failure, achieving point-in-time recovery within the required five-minute window. On the CompTIA Cloud+ CV0-004 exam, this scenario tests your understanding of recovery point objectives (RPO) and the difference between full, differential, and log-based backups—a common trap is choosing daily full backups alone, which lose all transactions after the backup completes. Remember the mnemonic “Full for foundation, logs for precision” to recall that full backups provide the base restore point while frequent transaction logs deliver the fine-grained recovery needed for continuously updated databases.
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.
An administrator is configuring a backup policy for a critical application database. The policy must allow point-in-time recovery up to the last 5 minutes. The database is updated continuously throughout the day. Which of the following backup strategies BEST meets the requirement?

Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Daily full backups plus transaction log backups every 5 minutes.
Option C is correct because a combination of full daily backups and transaction log backups allows point-in-time recovery. Option A is wrong because snapshots are not transaction-consistent. Option B is wrong because daily full backups alone lose transactions. Option D is wrong because weekly full backups are too infrequent.
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.
✗
Weekly full backups with daily differential backups.
Why it's wrong here
Differential backups are cumulative and do not allow point-in-time recovery.
✗
Hourly snapshots of the virtual machine.
Why it's wrong here
Snapshots capture state but may not be transaction-consistent and lack granularity.
✓
Daily full backups plus transaction log backups every 5 minutes.
Why this is correct
Transaction logs enable recovery to any point within the last 5 minutes.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Daily full backups of the database.
Why it's wrong here
Daily backups would lose up to 24 hours of data.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
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 CV0-004 NAT questions on configuration and troubleshooting.
