This CCSP practice question tests your understanding of cloud security operations. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 has a disaster recovery (DR) plan that includes failing over to a secondary cloud region. The plan was tested six months ago and worked, but since then significant infrastructure changes have been made. Which of the following should the company do to ensure the DR plan remains effective?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Conduct a tabletop exercise now, followed by a partial failover test of critical applications.
Option B is correct because iterative tabletop exercises and partial failovers validate changes without full disruption. Option A is wrong because one annual test is insufficient given the changes. Option C is wrong because documentation updates without testing are risky. Option D is wrong because automating fails reduces human error but still requires validation.
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.
✗
Wait until the next annual DR test to verify the changes.
Why it's wrong here
Delaying testing for a year could leave the organization unprotected.
✗
Automate the entire failover process to eliminate human error.
Why it's wrong here
Automation is good but still needs testing to ensure it works with the changes.
✗
Update the DR documentation to reflect the changes and assume the plan still works.
Why it's wrong here
Documentation alone does not verify actual functionality.
✓
Conduct a tabletop exercise now, followed by a partial failover test of critical applications.
Why this is correct
Tabletop and partial failover identify gaps quickly and are less disruptive.
Related concept
Static NAT maps one inside address to one outside address.
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 security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
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 CCSP NAT questions on configuration and troubleshooting.
